Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a printing device that performs printing on a plurality of types of continuous paper, and detects the paper type of the continuous paper while feeding out the continuous paper, and performs error control of the printing device that performs print control according to the detected paper type The present invention relates to a method, a program, and a printing apparatus.
[0002]
[Prior art]
Conventionally, a label sheet in which a plurality of labels are arranged at a predetermined interval on a long mount, a marked sheet in which a mark is attached to a long sheet at a predetermined interval, and a long plain sheet. 2. Description of the Related Art Printing apparatuses that perform printing on a plurality of types of continuous paper such as certain plain paper are known. This type of printing apparatus stores the continuous paper in a wound state, periodically detects the paper type of the continuous paper fed from the paper storage unit, and determines the paper type based on the detection result. The printing control is performed accordingly (see, for example, Patent Document 1).

[0004]
By the way, a printing apparatus capable of printing on such a plurality of types of continuous paper and containing the continuous paper in an exposed state without being contained in the cartridge detects which continuous paper is contained. Therefore, it is necessary to feed out continuous paper (when continuous paper is stored in a cartridge, the paper type can be specified by detecting the cartridge, and thus it is often unnecessary to feed out continuous paper). For this reason, if the paper type is detected every time the paper is replaced, such as when the continuous paper has been used up (when the paper has run out), the continuous paper is fed out each time, resulting in wasted paper. It will end up.
[0005]
In order to solve this problem, the detected paper type is stored, and the continuous paper is replaced until the paper type is updated (set) by the user. There is known a method of performing print control suitable for the continuous paper without detecting it (without feeding the continuous paper).
[0006]
In this case, if different paper types are accommodated, the detection result does not match the stored paper type and an error occurs. However, for error recovery (recovery), for example, error recovery as shown in FIG. Operation was necessary. That is, after an error occurs, the power is turned off by the user (S101), and the cover of the paper storage unit is opened (S102). Subsequently, when the power is turned on while the paper feed switch is pressed (S103), the error recovery mode is set. In the error recovery mode, the original paper feed function of the switch for paper feed is lost. When the switch is pressed six times (S104) and the lid is closed by the user (S105), the paper feed is started. The paper type is updated based on the detection result detected during paper feeding (S106). As described above, the error recovery operation requires a complicated operation in which an error recovery cannot be erroneously performed by a normal operation.
[0007]
[Problems to be solved by the invention]
However, such an error recovery operation is not a problem when the frequency of replacement with different continuous sheets is small, but it is a very troublesome operation for a user with a high frequency of replacement.
[0008]
In view of the above-described problems, the present invention can print on a plurality of types of continuous paper, and when performing print control based on the detection result of the continuous paper, minimize waste of paper for detection. An object of the present invention is to provide a printing apparatus error recovery method, a program, and a printing apparatus that can easily perform error recovery.
[0009]
[Means for Solving the Problems]
An error recovery method for a printing apparatus according to the present invention includes a label sheet in which a plurality of labels are arranged at a predetermined interval on a long mount, and a mark with a mark added to the long sheet at a predetermined interval.

A paper type update process is included, in which continuous paper is fed out to detect the paper type as the body is closed, and the stored paper type is updated based on the detection result.
[0010]
Further, the printing apparatus of the present invention includes a label sheet in which a plurality of labels are arranged on a long mount with a predetermined interval, and a marked sheet in which a mark is attached to the long sheet at a predetermined interval. In a printing apparatus that performs printing on a plurality of types of continuous paper including at least one of plain paper that is a long plain paper, a paper storage unit that stores the continuous paper in a wound state; A cover that covers the paper storage unit, a paper type detection unit that periodically detects the paper type of the continuous paper that is fed out while feeding the continuous paper, and print control that performs print control according to the detected paper type And a paper type storage unit that continuously stores the detected paper type until the paper type is updated, and a determination unit that determines whether or not the detected paper type matches the stored paper type Matches the paper type If it is determined that there is no error, and / or if it is determined that it is difficult to continue printing, error notification means for performing error notification, and error recovery for performing error recovery by opening and closing the lid by the user after the error notification of the error notification means The error recovery means includes a paper type update means for detecting the paper type by the paper type detection means after the lid is closed and updating the paper type stored in the paper type storage means. It is characterized by.
[0011]
According to these configurations, since print control is performed according to the detected paper type, it is possible to perform print control suitable for the stored continuous paper without the user's trouble of paper setting. Further, since the detected paper type is continuously stored until the paper type is updated, it is not necessary to detect the continuous paper every time the paper is replaced such as when the paper is out. Therefore, paper is not unnecessarily wasted. In addition, after the error notification, the user can perform error recovery by opening and closing the lid, and in this case, in order to detect and update the paper type, the user performs an operation for paper type update (paper setting). Do not need. That is, since error recovery and paper setting can be performed easily and quickly, user convenience can be greatly improved.
[0012]
In this case, when the paper type is updated to the label paper or the marked paper in the paper type update step, the error recovery step preferably includes a cueing step for cueing continuous paper.
[0013]
In this case, when the paper type is updated to the label paper or the marked paper by the paper type updating means, the error recovery means preferably includes a cueing means for cueing continuous paper.
[0014]
According to these configurations, when the paper type is updated to the label paper or the marked paper, the continuous paper is continuously cued, so that the user starts printing from an appropriate position when using any continuous paper. be able to. In addition, since the cueing is completed when the error is recovered, the printing operation can be resumed immediately after the cueing.
[0015]
In these cases, in the paper type detection step, it is preferable to detect the paper type based on the transmitted and received light levels of the light irradiated on the continuous paper.
[0016]
In these cases, the paper type detection means further includes a transmission type optical sensor for detecting the transmission / reception level of the light applied to the continuous paper, and a reflection type optical sensor for detecting the reflection / reception level of the light applied to the continuous paper. Preferably, the paper type is detected based on the transmitted light reception level and the reflected light reception level.
[0017]
According to these configurations, it is possible to reliably detect the paper type with a simple configuration in which the continuous paper is irradiated with light and the paper type is detected based on the transmitted / received light reception level and the reflected light reception level.
[0018]
In this case, in the determination step, it is determined that the paper is out when the transmitted / received light level is higher than the reference value and the reflected light reception level is lower than the reference value. In the error notification step, the paper is out of paper in the determination step. If it is determined, it is preferable to perform error notification.
[0019]
In this case, the determining means determines that the sheet is out of paper when the transmitted light receiving level is higher than the reference value and the reflected light receiving level is lower than the reference value, and the error notifying means is determined by the determining means. When it is determined that the paper is out, it is preferable to perform error notification.
[0020]
According to these configurations, it is possible to instantaneously determine whether the paper is out, regardless of the paper type. Therefore, error notification can be performed promptly.
[0021]
In this case, in the error notification step, it is preferable that the error notification when it is determined that the sheet is out of paper and the other error notifications are differentiated and notified.
[0022]
Further, in this case, it is preferable that the error notification means differentiates and notifies the error notification when it is determined that the paper has run out and other error notifications.
[0023]
According to these configurations, since the error notification when it is determined that the paper is out is differentiated from other error notifications, the user can instantly perform the error without checking the continuous paper stored in the printing apparatus. Can be grasped (at least whether or not there is a paper out error).
[0024]
In these cases, it is preferable to store the paper type in the nonvolatile memory in the paper type storage step.
[0025]
In these cases, it is preferable that the paper type storage means is constituted by a nonvolatile memory.
[0026]
According to these configurations, since the paper type is stored in the nonvolatile memory, it is not necessary to detect the paper type when the same type of continuous paper is used even after the power is turned off. Accordingly, it is possible to further reduce paper waste.
[0027]
In these cases, in the error recovery process, it is preferable to perform error recovery with only opening and closing of the lid body without requiring the power key on / off operation.
[0028]
Further, in these cases, a power key for instructing power supply is further provided, and the error recovery means does not require an on / off operation of the power key, and an error occurs when the lid is opened and closed only once. It is preferable to perform a return.
[0029]
According to these configurations, since the power key does not need to be turned on / off at the time of error recovery, various setting information is not lost. Further, the user can perform error recovery more quickly by a simple operation of opening and closing the lid once.
[0030]
A program according to the present invention is characterized by causing each step in the error recovery method for a printing apparatus according to any one of the above to be executed.
[0031]
According to this configuration, it is possible to print on a plurality of types of continuous paper, and in a printing apparatus that performs print control based on the detection result of the continuous paper, easily while minimizing waste of paper for detection. A program that can perform error recovery can be provided.
[0032]
DETAILED DESCRIPTION OF THE INVENTION

The printing apparatus of the present embodiment is capable of printing on a plurality of types of continuous paper and is configured to perform print control according to the detected paper type. In this case, since the detected paper type is continuously stored until the paper type is updated (reset), it is not necessary to detect the continuous paper every time the paper is replaced, such as when the paper is out. As a result, waste of paper for paper detection can be eliminated. In addition, after error notification, the user can easily and quickly return the error and update the paper type by opening and closing the lid, so there is no need for special operation for paper setting by the user, greatly improving usability. Can be made. In view of this, a printing apparatus connected to a host computer and performing printing based on print data and control data transmitted from the host computer will be described as an example.
[0033]
FIG. 1 is a perspective view of a printing apparatus according to an embodiment of the present invention in a vertically placed state, FIG. 2 is a perspective view of a state in which a lid of the printing apparatus is opened, and FIG. 3 is a horizontally placed printing apparatus. FIG. 4 is a sectional view showing a state in which the lid of the printing apparatus is opened. As shown in these drawings, the printing apparatus 10 according to the present embodiment is used in two postures, that is, a vertical posture in which the printed continuous paper P (roll paper) is discharged from the front surface and a horizontal posture in which the continuous paper P is discharged from the upper surface. Although it is possible, the following description will be based on the horizontal orientation.
[0034]
The printing apparatus 10 includes a casing 11 having an upper opening, and a lid 12 that covers the upper opening so that the upper opening can be opened and closed. By opening the lid 12, the continuous paper P can be replaced and the inside can be maintained. Inspection is possible. The continuous paper P is stored in the paper storage unit 25 inside the printing apparatus directly (in an exposed state) without being stored in a case such as a cartridge in a wound state. Further, the leading end side of the continuous paper P fed out from the paper storage unit 25 is guided out of the housing from the paper discharge port 14 via the transport path 13.
[0035]
The printing apparatus 10 is connected to a host computer 100 (see FIG. 8) via a connector or the like, and performs printing control in accordance with a printing instruction from the host computer 100. That is, according to a print instruction from the host computer 100, the print head (thermal head) 15, the platen roller 16, and the cutter mechanism 17 arranged on the conveyance path 13 are appropriately driven, and the continuous paper P is discharged to the discharge port 14. The paper is conveyed (the continuous paper P is fed out), and characters (characters, symbols, etc.) and pictures are printed along with the conveyance. Then, the printing is completed, the continuous paper P is further conveyed, and when the rear end position of the printed portion reaches the cutting position of the cutter mechanism 17, it is cut and separated by the cutter mechanism 17, and a single sheet is cut from the paper discharge port 14. Provide to users as paper.
[0036]
In addition, a plurality of LEDs 41, 42, and 43 that display various errors in the printing apparatus 10 are provided on the top surface of the housing 11 (the front surface in the case of the vertical installation in FIG. 1). For example, when the paper stored in the paper storage unit 25 is used up (when the paper runs out), an error is notified by the paper out error LED 41, and the paper previously stored in the flash ROM 250 (see FIG. 8) is stored. When the type and the paper type detected by the paper type detection sensor 21 (see FIG. 5) are different (details will be described later), an error is notified by the paper difference error LED 42, and other errors that make it difficult to continue printing. When the error occurs, an error is notified by the other error LED 43.
[0037]
As a notification method, each LED 41, 42, 43 may be turned on or blinked. Further, a beep sound (electronic sound) or the like may be generated together with the display of the LEDs 41, 42, and 43 to notify the user of the error more effectively.
[0038]
By the way, as described above, the printing apparatus 10 of the present embodiment performs printing control suitable for the continuous paper P by detecting the paper type of the continuous paper P. This is performed by a paper type detection sensor 21 (a transmission / reflection optical sensor) disposed in the vicinity of the upstream side of the print head 15 in the transport path 13.
[0039]
FIG. 5 is an enlarged cross-sectional view of the paper type detection sensor 21. As shown in FIG. 5, the paper type detection sensor 21 is composed of front and back sensor units 21 a and 21 b that are opposed to each other with the conveyance path 13 interposed therebetween. Yes. The front side sensor unit 21a facing the front surface (printing surface) of the continuous paper P is provided on the printing apparatus main body side, and a light emitting element 22 for transmission is incorporated therein. The transmissive light-emitting element 22 is disposed to face the light-receiving element 23 and constitutes a transmissive optical sensor 31 with the transmissive light-emitting element 22 and the light-receiving element 23 as a pair. On the other hand, the back-side sensor unit 21b facing the back surface (non-printing surface) of the continuous paper P is provided on the lid 12 side, and includes a reflective light-emitting element 24 and a light-receiving element 23 incorporated therein, as a pair. A sensor 32 is configured.
[0040]
The light emitting element 22 for transmission and the light emitting element 24 for reflection are driven to emit light alternately at every paper feed pitch (1 dot), and the light receiving element 23 alternately outputs a transmitted light receiving level signal and a reflected light receiving level signal accordingly. To do. For example, when one dot is formed by four steps of the paper feed stepping motor 122 (see FIG. 8), the light emission elements 22 and 24 are alternately driven every four steps in synchronization with the drive pulse of the paper feed stepping motor 122. Is switched to.
[0041]
Next, an example of the continuous paper P applicable to the printing apparatus 10 of the present embodiment will be described with reference to FIG. FIG. 4A shows a plain paper P1 which is a long plain paper, and FIG. 4B shows a label 19 having a predetermined length L1 on a long mount 18 with a predetermined interval L2. A plurality of label sheets P2 are shown, and FIG. 10C shows a marked sheet P3 in which a mark (black mark) 20 having a mark length L3 is attached to one side of a long sheet at a predetermined interval L4. Is shown. Note that the printing surface (front surface) of each continuous paper P is the upper side in the drawing for the plain paper P1 and the label paper P2, and the lower side in the drawing for the marked paper P3.
[0042]
The printing apparatus 10 of the present embodiment can print on a plurality of types of continuous paper P including the continuous paper P shown here. Further, the longitudinal length L1 and the label interval L2 of the label 19 on the label paper P2, and the form, color, and arrangement position of the mark 20 on the marked paper P3 (in the drawing, the left side, the center, the right side, etc. ) And mark interval L4 can be arbitrarily set, and a plurality of continuous sheets P having different modes can be used.
[0043]
Here, with reference to FIG. 7, the transmission / reception level and reflection / reception level of each sheet when the above-described continuous sheet P is detected by the sheet type detection sensor 21 will be described. As shown in FIGS. 4A and 4B, when the marked paper P3 is used, the transmitted / received light level is L (lower) than the reference value (threshold value: described later) A regardless of the paper position. It becomes. Further, the reflected light reception level is H (higher) than the reference value (threshold value) B in the blank paper portion, and is L lower than the reference value B in the mark portion. Therefore, in the normal printing process using the marked paper P3, the reference position (marked portion) is determined based on the reflected light reception level without using the transmitted light reception level (used for paper out detection) and printed at a predetermined position. I do.
[0044]
On the other hand, when the label paper P2 is used, the transmitted / received light level is L lower than the reference value A in the label portion and H higher than the reference value A in the mount portion. Further, the reflected light reception level is higher than the reference value B regardless of the paper position. Therefore, in the normal printing process using the label paper P2, the reference position (mounting portion) is discriminated based on the transmitted light reception level without using the reflected light reception level (used for paper out determination), and printing is performed at a predetermined position. Do.
[0045]
When the plain paper P1 is used, the transmitted / received light level is lower than the reference value A and the reflected light received level is higher than the reference value B regardless of the paper position. Accordingly, in the normal printing process using the plain paper P1, any light reception level (transmission in the present embodiment) is used for paper out determination. Further, when the transmitted / received light level is H higher than the reference value A and the reflected light received level is L lower than the reference value B, it is determined that the sheet is out of paper (no paper) regardless of the type of paper.
[0046]
Here, the control configuration of the printing apparatus 10 will be described with reference to the control block diagram of FIG. The printing apparatus 10 includes a paper out error LED 41, a paper difference error LED 42, and other error LEDs 43, a display unit 110 that displays various errors, a paper storage unit 25 that stores continuous paper P, and a print head (thermal head). ) 15 and a paper feed unit 121 that conveys the continuous paper P by the paper feed motor 122, a printing unit 120 that performs printing on the continuous paper P based on print data transmitted from the host computer 100, and a paper cutter A cutting unit 130 (cutter mechanism 17) for cutting the rear end of the printed portion of the continuous paper P, and a lid detection sensor 142 for detecting opening and closing of the lid 12. A paper detection sensor 143 that detects loading or non-loading of continuous paper (roll paper) P stored in the paper storage unit 25; The sheet type detection sensor 21 including the over-type optical sensor 31 and the reflection-type optical sensor 32 has a detection unit 140 that performs various detections, a display driver 151, a head driver 152, and a motor driver 153 (feed motor driver 153a, cutter). The motor driver 153b) includes a drive unit 150 that drives each unit, and a control unit 200 that is connected to each unit and controls the entire printing apparatus 10.
[0047]
The control unit 200 includes a CPU 210, a ROM 220, a character generator ROM (CG-ROM) 230, a RAM 240, a flash ROM 250, and an input / output control device (hereinafter referred to as “IOC: Input Output Controller”) 260, which are connected to each other via an internal bus 270. Has been. The ROM 220 stores a control program block 221 for storing various programs to be processed by the CPU 210 in addition to a program for performing printing control according to the paper type, and detection results (transmission light reception level and reflection light reception level) of the paper type detection sensor 21. A control data block 222 for storing control data including a discrimination table (see FIG. 7B) for specifying the paper type according to the data and data relating to a threshold value set at the time of shipment of the printing apparatus 10; have. Further, the CG-ROM 230 stores font data of characters and symbols, and outputs the corresponding font data when code data specifying the character or the like is given. The CG-ROM 230 may be omitted depending on the processing capability of the host computer 100.
[0048]
The RAM 240 has a print data block 242 for storing print data transmitted from the host computer 100 in addition to various work area blocks 241 used as flags and the like, and is used as a work area for control processing.
[0049]
The flash ROM 250 stores a paper type data block 251 for storing data relating to the paper type specified based on the detection result detected by the paper type detection sensor 21, and a threshold value (setting) serving as a reference value for specifying the paper type. The threshold data block 252 for storing the threshold value (see FIG. 10) is stored, and is continuously stored until the paper type is updated. Of course, since it is the flash ROM 250, the stored data is not lost even if the power is turned on / off. The update of the paper type is executed with the user opening and closing the lid 12 as a trigger after the error notification by the LEDs 41, 42, and 43 of the display unit 110. The details will be described later. The flash ROM 250 shown here can be substituted for various nonvolatile memories. In other words, any storage medium may be used as long as it does not lose the data stored when the power is turned off.
[0050]
In the IOC 260, a logic circuit for supplementing the function of the CPU 210 and handling interface signals with various peripheral circuits is configured and configured by a gate array, a custom LSI, or the like. As a result, the IOC 260 takes the print data and control data from the host computer 100 as they are or processes them and imports them into the internal bus 270, and in conjunction with the CPU 210, outputs the data and control signals output from the CPU 210 to the internal bus 270. The data is output to the drive unit 150 as is or after being processed.
[0051]
With the above configuration, the CPU 210 inputs various signals and data from each unit in the host computer 100 and the printing apparatus 10 via the IOC 260 in accordance with the control program in the ROM 220, and the font data from the CG-ROM 230 and the RAM 240. Process and output various signals and data to each unit in the printing apparatus 10 via the IOC 250, thereby controlling the printing process and the error recovery process suitable for the paper type stored in the flash ROM 250. Etc.
[0052]
Next, error recovery processing of the printing apparatus 10 will be described with reference to FIG. As described above, when the printing apparatus 10 uses up all the sheets stored in the sheet storage unit 25, when the sheet type stored in the flash ROM 250 (see FIG. 8) differs from the detected sheet type, When an error that makes it difficult to continue printing occurs, an error is notified by the LEDs 41, 42, and 43. After the error is notified, the lid 12 can be opened and closed to recover (recover) the error.
[0053]
As shown in the flowchart of FIG. 9, when the user first opens and closes (closes after opening) the lid (cover) 12 in an error state (S1), the printing apparatus 10 is detected by the lid detection sensor 142. Is detected, and error recovery processing is performed (S2). In the error recovery process, two processes are performed: determination of out of paper and setting of a threshold value (first process), determination / update of paper type, and cueing (second process). In other words, the user only needs to open and close the lid body 12 once, and the error recovery can be performed easily and quickly.
[0054]
Here, the error recovery process will be described with reference to FIGS. As described above, as the error recovery process, the first process for determining the out of paper and setting the threshold value, and the second process for determining / updating the paper type and cueing are performed. The threshold value set in the first process is hereinafter referred to as “level value” in distinction from the threshold value (initial threshold value) stored at the time of shipment of the printing apparatus 10. The level values A and B set in the first process are reflected in paper type discrimination / update and cueing in the second process, and the paper discrimination result in the second process is reflected in the normal printing process. Further, the level value A is a discrimination reference value used for discrimination of the transmitted / received light level, and the level value B is a discrimination reference value used for discrimination of the reflection / reception level (see FIG. 7A).
[0055]
First, the procedure of the first process will be described with reference to the flowchart of FIG. When the first process starts, the transmitted light reception level, which is the output of the transmissive light receiving sensor 31, is input (S11), and it is determined whether or not the transmitted light reception level is equal to or lower than the threshold value A (initial threshold value A). (S12). When the transmitted / received light level is greater than the threshold value A (S12: No), the reflected / received light level that is the output of the reflective light receiving sensor 32 is input (S13), and the reflected / received light level is set to the threshold value B (initially It is determined whether or not it is equal to or less than the threshold value B) (S14). Here, when the reflected light reception level is equal to or lower than the threshold value B (S14: Yes), it is determined that the paper is out, and the paper out error LED 41 is turned on as paper out error processing (S15).
[0056]
On the other hand, if the transmitted light reception level is equal to or lower than the threshold value A (S12: Yes), paper feeding is started (S16), and it is confirmed that it is not the mount portion of the label paper P2, and the transmitted light reception level is acquired (S17). At the same time, it is confirmed that it is not the mark portion of the marked paper P3, and the reflected light reception level is acquired (S18). The confirmation that it is not the mount portion is performed on the condition that the transmitted and received light level does not change more than 1.5 times during a predetermined amount (L2 or more and L3 or more: see FIG. 6) of paper feeding. Confirmation that the mark portion is not a mark portion is performed on the condition that the reflected light reception level does not change more than 0.6 times during the predetermined amount of paper feeding.
[0057]
Thereafter, it is determined whether or not the acquisition of both light reception levels has been completed normally (S19). If an error is determined here (if the light reception level cannot be acquired normally (S19: Error)), an error is detected. As a process, the other error LED 43 is turned on (S20). If the transmitted light reception level other than the mount portion and / or the reflected light reception level other than the mark portion cannot be acquired (S19: No), each light reception level is acquired while continuing paper feeding. On the other hand, when both the received light levels are acquired normally (S19: Yes), 1.5 times the acquired transmitted / received light level is set as the level value A (S21), and 0.6 times the acquired reflected light received level is set. The level value B is set (S22). Thus, the level values A and B corresponding to the continuous paper P are set (updated) based on the light reception level of the continuous paper P currently stored. The set level value is stored in a threshold data block 252 (see FIG. 8) in the flash ROM 250.
[0058]
In the first process, in the error recovery process after the paper out error notification (S15), it is preferable to detect the loading of the continuous paper P by the paper detection sensor 143 (see FIG. 8) at the start of the process. In this case, when the loading of the continuous paper P is not detected, the out-of-paper error process can be performed again without determining the transmitted light reception level and the reflected light reception level. That is, according to this configuration, the processes of S11 to 14 can be omitted.
[0059]
Next, the procedure of the second process will be described with reference to the flowchart of FIG. When the second process is started, paper feeding is started (S31), and the transmitted / received light level is input (S32), and it is determined whether or not the transmitted / received light level is equal to or higher than the level value A (S33). If it is determined that the level is greater than or equal to the level value A (S33: Yes), the reflected light level is input (S34), and it is determined whether the reflected light level is equal to or lower than the level value B (S35). . If the value is equal to or lower than the level value B (S35: Yes), it is determined that the paper is out, and the paper out error LED 41 is turned on as paper out processing (S36), and the second processing (error recovery processing). Exit. In this case, the lid 12 is opened by the user, and after the continuous paper P is loaded, the lid 12 is closed, so that the error recovery process is executed again. On the other hand, if the reflected light reception level is greater than the level value B (S35: No), it is determined that the sheet is the label sheet P2, and the sheet type data block 251 (see FIG. 8) is updated (S37). After performing cueing (S38), the process is terminated.
[0060]
When it is determined that the transmitted light reception level is smaller than the level value A (S33: No), the reflected light reception level is input (S39), and it is determined whether the reflected light reception level is equal to or lower than the level value B (S40). ). If it is equal to or lower than the level value B (S40: Yes), it is determined that the sheet P3 is marked, the sheet type data block 251 is updated (S41), and the cueing for marked sheet (S42) is performed. After execution, the process is terminated.
[0061]
On the other hand, if the reflected light reception level is greater than the level value B (S40: No), it is determined whether or not the paper feed amount is a predetermined amount L (L1 or more and L4 or more) (S43). If it is determined that the feed amount is greater than or equal to the predetermined amount L (S43: Yes), it is determined that the sheet is plain paper P1, the paper type data block 251 is updated (S44), and processing is performed without performing cueing. Exit. If the paper feed amount does not reach the predetermined amount L (S43: No), the determination of each light reception level is repeated while continuing the paper feed, and if the light reception level changes, the change is made accordingly. While the continuous paper P is discriminated, the plain paper P1 is discriminated when the paper feed amount reaches the predetermined amount L without changing the light receiving level.
[0062]
As described above, according to the present invention, the plain paper P1, the label paper P2, and the marked paper are used to determine the type of the continuous paper P based on the detection result (the transmitted light reception level and the reflected light reception level) of the paper type detection sensor 21. Although it corresponds to a plurality of types of continuous paper P including any one of P3, it is possible to perform an appropriate printing process according to the type of the paper without performing a setting change operation when changing the paper. As a result, it is possible not only to reduce the operation burden on the user, but also to avoid the occurrence of trouble due to setting errors or the like.
[0063]
In addition, when the transmitted light reception level is high and the reflected light reception level is high, it is determined that the label paper P2 is received. Therefore, the paper determination ends when the mount portion of the label paper P2 reaches the light reception level detection position. As a result, the time required for paper discrimination can be shortened and a quick error recovery process can be performed. Similarly, when the transmitted light receiving level is low and the reflected light receiving level is low, it is determined that the paper is marked P3. Therefore, the paper determination is completed when the mark portion of the marked paper P3 reaches the light receiving level detection position. As a result, the time required for paper discrimination can be shortened and quick error recovery processing can be performed.
[0064]
Further, when the continuous light P is conveyed by a predetermined amount L, when the state of the transmitted light reception level is low and the reflection light reception level is high, the label paper P2 and the marked paper are determined in order to determine that it is the plain paper P1. In addition to P3, plain paper P1 can be identified, and as a result, the versatility of the printing apparatus 10 can be enhanced. Further, since the predetermined amount L is larger than the label length L1 of the label paper P2 and larger than the inter-mark distance L4 of the marked paper P3, the label portion of the label paper P2 and the blank portion of the marked paper P3 are used as plain paper. There is no misunderstanding of P1. Further, when the transmitted light reception level is high and the reflected light reception level is low, it is determined that the paper is out, so it is possible to instantaneously determine the paper out state regardless of the type of paper. This makes it possible to quickly run out of paper.
[0065]
Further, as the first error recovery process, the level values A and B used for determining the level of the transmitted light reception level and the reflected light reception level after the lid is closed are set based on the light reception level of the set continuous paper P. The threshold values A and B can be updated. As a result, the level of the received light level can be accurately determined not only by the difference in type but also by using continuous paper P having different paper thickness, paper quality and the like.
[0066]
Further, when acquiring the transmission / reception level that becomes the reference of the level value A, it is confirmed that it is not the mount portion of the label paper P2, and when acquiring the reflection / reception level that becomes the reference of the level value B, the marked paper P3 is used. Therefore, it is possible to prevent level setting based on an inappropriate reference value and to accurately determine the level of the received light level.
[0067]
In the above example, the paper feed amount (predetermined amount L) for determining the paper type is larger than the label length L1 of the label paper P2 and larger than the inter-mark distance L4 of the marked paper P3. However, in this case, the user may select a plurality of types of paper feed amounts (predetermined amount L) from a plurality of candidates (for example, 16 [cm], 30 [cm], etc.) using a memory switch or the like. . According to this configuration, according to the user's needs, the paper feed amount can be shortened to increase the processing speed, or the paper feed amount can be lengthened to increase the processing accuracy.
[0068]
In this case, it is preferable to feed the paper several centimeters (for example, 2 [cm], etc.) longer than the set paper feed amount L. According to this configuration, the paper type can be detected more reliably.
[0069]
Next, a series of processing during normal printing will be described with reference to FIGS. FIG. 12 shows a processing procedure when the paper type is set to plain paper P1, and FIG. 13 shows a processing procedure when the paper type is set to label paper P2.
[0070]
First, a case where the paper type is set to plain paper P1 will be described. As shown in the flowchart of FIG. 12, when the power is turned on by the user, paper type data is acquired (S61). Here, the paper type stored in the paper type data block 251 of the flash ROM 250, that is, the previously set paper type (here, “plain paper”) is acquired. Here, when the continuous paper P is not stored in the paper storage unit 25, or when the continuous paper P is terminated by paper feeding or the like by printing, the printer is in an offline state (command cannot be transmitted) (S62). ). Accordingly, when the lid 12 is opened by the user (S63) and the continuous paper P is loaded (S64), and then the lid 12 is closed (S65), the user enters an online state and is accompanied by paper feeding. It is determined whether or not the sheet is out of paper (S66).
[0071]
Here, as in the error recovery process described above, it is determined whether the paper is out based on the transmitted light reception level and the reflected light reception level. If it is determined that the paper is out (S66: Yes), the paper out error LED 41 is turned on. Error recovery processing is executed (S67, see FIG. 9). On the other hand, if it is not out of paper (S66: No), the printer waits until print data is acquired from the host computer 100 (S68).
[0072]
When the print data is acquired from the host computer 100, printing is executed (S69), and the transmitted light reception level and the reflection light reception level are acquired periodically (every four steps of the paper feed stepping motor 122) to determine whether the paper is out ( S70). If it is determined that the paper is out (S70: Yes), the paper out error LED 41 is turned on and error recovery processing is executed (S67) as in the above case. On the other hand, if it is not out of paper (S70: No), it is determined based on the transmitted light reception level and the reflected light reception level whether it is other than plain paper P1 (whether it is label paper P2 or marked paper P3) (S71). ) If it is other than plain paper P1 (S71: Yes), the paper difference error LED 42 is turned on (S72), and error recovery processing is executed. On the other hand, if it is determined that the paper is plain paper P1 (S71: No), printing is continued (S69).
[0073]
As described above, when the plain paper P1 is set, the cueing process is not performed. Therefore, immediately after the lid 12 is closed, it is determined that the paper is out (S66), and the difference between papers (S71) is printed. This is performed in accordance with the execution (paper feed).
[0074]
Next, a case where the paper type is set to label paper P2 will be described. As shown in the flowchart of FIG. 13, when the power is turned on by the user, paper type data is acquired (S81). Here, the paper type (here, “label paper”) stored in the paper type data block 251 of the flash ROM 250 is acquired. Further, when the continuous paper P is not stored in the paper storage unit 25, or when the continuous paper P is finished by paper feeding by printing or the like, the paper-free offline is set (S82). Accordingly, when the lid 12 is opened by the user (S83) and the continuous paper P is loaded (S84), and then the lid 12 is closed (S85), the user enters an online state, and the head for the label paper (S86).
[0075]
Here, the transmitted light reception level and the reflected light reception level are acquired along with this cueing. As a result, when it is determined that the paper is out (S87: Yes), the paper out error LED 41 is turned on and the error recovery process is executed ( S88, see FIG. 9). On the other hand, if the sheet is not out (S87: No), it is the label paper P2 other than the label paper P2 (whether it is the marked paper P3 or the plain paper P1) or the level value is different based on the transmitted light reception level and the reflected light reception level. (S89), if it is determined that the label sheet P2 is different from the set label sheet P2 (S89: Yes), The paper difference error LED 42 is turned on (S94), and error recovery processing is executed. On the other hand, if it is determined that the label paper P2 is the same as the set label paper P2 (S89: No), the printer waits until print data is acquired from the host computer 100 (S90).
[0076]
When print data is acquired from the host computer 100, printing is executed (S91), and the transmitted light reception level and reflected light reception level are acquired periodically (every four steps of the paper feed stepping motor 122) to determine whether the paper is out. (S92). If it is determined that the paper is out (S92: Yes), the paper out error LED is turned on and error recovery processing is executed as in the above case. On the other hand, if it is determined that the sheet is not out of paper (S92: No), it is determined whether the label sheet P2 has a different layout (label length L1 and / or label length) based on the transmitted light reception level and reflected light reception level acquired during printing. Alternatively, it is determined whether or not the label interval L2 is different (S93). If the layout is different (S93: Yes), the paper difference error LED 42 is turned on (S94), and error recovery processing is executed. On the other hand, if the layout is not different (if it is determined that it is the same as the set label paper P2 (S93: No)), printing is continued (S91).
[0077]
As described above, when the label paper P2 is set, the cueing is performed immediately after the lid 12 is closed (S86), and accordingly, the paper runs out, the marked paper, the plain paper, or the level value is different. The label paper is discriminated (S87, S89). In addition, with the execution of printing (paper feeding), a label paper with a different layout is discriminated (S93).
[0078]
In the case of setting the marked paper P3, as in the above-described example of the label paper P2, the cueing is performed immediately after the lid 12 is closed. A plain paper or a label paper with a different level value is discriminated (in this case, the disc is discriminated based on the level value B). In addition, with the execution of printing (paper feeding), a sheet with a layout difference mark is determined.
[0079]
As described above, according to the first embodiment of the present invention, print control is performed according to the detected paper type, so that the user does not need to set paper and print control suitable for the stored continuous paper P is performed. It can be performed. Further, since the detected paper type is continuously stored until the paper type is updated, it is not necessary to detect the continuous paper P every time the paper is replaced such as when the paper is out. Therefore, the continuous paper P is not unnecessarily wasted. Further, after the error notification, the user can easily recover from the error by opening and closing the lid 12 once. Further, in this case, the paper type is updated by the user (paper type) in order to detect and update the paper type. Operation for setting) is not required. That is, since error recovery and paper setting can be performed easily and quickly, user convenience can be greatly improved.
[0080]
Next, error recovery processing according to the second embodiment of the present invention will be described with reference to FIG. In the error recovery process of the first embodiment (see S2 in FIG. 9), in the first process, a level value is set as a reference value for paper type discrimination, and the second process is performed using the level value. In this embodiment, the paper type is determined using the initial threshold value set at the time of shipment of the printing apparatus 10, and then used for determining the difference in paper. Set the level value. Further, by adopting a paper type discriminating step different from that in the first embodiment (refer to S32 to S44 in FIG. 11 for the paper type discriminating step in the first embodiment), various types of continuous paper P can be used. There is an effect that it can be accurately discriminated. Thus, differences from the first embodiment will be mainly described.
[0081]
In the error recovery process according to the present embodiment, as shown in the flowchart of FIG. 14, paper is fed (S201), and the received light level during transmitted light emission and the received light level during reflected light emission are acquired (S202). Here, when the transmitted light reception level is equal to or higher than the threshold value A (initial threshold value A) and the reflected light reception level is equal to or lower than the threshold value B (initial threshold value B) (S203: Yes), the paper is out. And the paper out error LED 41 is turned on as a paper out error process (S204).
[0082]
On the other hand, when the condition that “the transmitted light reception level is equal to or higher than the threshold value A and the reflected light reception level is equal to or less than the threshold value B” is not satisfied (S203: No), the transmitted light reception level is equal to or lower than the threshold value A and the reflected light reception. It is determined whether or not the level is equal to or lower than the threshold value B (S205). If this condition is satisfied (S205: Yes), it is determined that the sheet is marked paper P3 and the paper type data block 251 is updated. (S206), a level value B serving as a reference of the reflected light reception level is set (S207). At this time, the level value B is set to 0.6 times the reflected and received light level other than the mark portion after paper feed of the mark length L3 or more. Then, after setting the level value B, cueing for marked paper is performed (S208), and the process ends.
[0083]
Further, when the condition that “the transmitted light reception level is equal to or lower than the threshold value A and the reflected light reception level is equal to or lower than the threshold value B” is not satisfied (S205: No), it is determined whether or not the transmitted light reception level is equal to or higher than the threshold value A. If it is determined (S209) and the condition is satisfied (S209: Yes), it is determined that the sheet is the label sheet P2, and the sheet type data block 251 is updated (S210). Is set (S211). At this time, the level value A is set to 1.5 times the transmission / reception level other than the length of the mount portion (label interval) L2 or more, that is, the transmitted / received level other than the mount portion. Then, after setting the level value A, cueing for label paper is performed (S212), and the process is terminated.
[0084]
If the transmitted light reception level is smaller than the threshold value A (S209: No), it is determined whether or not the paper feed amount is a predetermined amount L (L1 or more and L4 or more) (S213). If it is determined that the amount is equal to or greater than the predetermined amount L (S213: Yes), it is determined that the sheet is plain paper P1, the paper type data block 251 is updated (S214), and the cue and level values are set. End the process without doing it. If the paper feed amount does not reach the predetermined amount L (S213: No), the determination of both light reception levels is repeated while continuing the paper feed, and if the light reception level changes, the change is made accordingly. While the continuous paper P is discriminated, the plain paper P1 is discriminated when the paper feed amount reaches the predetermined amount L without changing the light receiving level.
[0085]
As described above, in this embodiment, the transmitted light reception level and the reflected light reception level are acquired at the same timing, and the paper type is determined based on them, so that the paper type can be accurately determined. For example, in the first embodiment (see FIG. 11), when the label paper P2 having a thick mount portion or a dark color of the mount portion is used, the transmitted / received light level does not exceed the level value A. May be. Further, in the first embodiment (first process), the paper out is determined based on the initial threshold value (see S11 to S15 in FIG. 10), so that the normal paper P1 having a small thickness (thin) is used. Then, since the transmitted light reception level is equal to or higher than the threshold value A and the reflected light reception level is equal to or lower than the threshold value B, there is a problem that it is determined that the sheet is out of paper.
[0086]
However, in the present embodiment, the transmitted light reception level and the reflected light reception level are acquired at the same timing, and the paper type is determined based on both the light reception levels. Therefore, it is possible to accurately determine the paper type and out of paper, and thus Various continuous sheets P (sheets having different thicknesses or colored mount parts or mark parts) can be used. Further, in the present embodiment, after specifying the paper type, in order to set a level value that is a reference value for paper difference discrimination, both level values A and B are set as in the first embodiment (FIG. 10). (See S21 and S22). Note that both the level values A and B are set after the plain paper update (S214), and even when the plain paper is set, the paper difference (see S71 in FIG. 12) is determined based on these two level values. May be.
[0087]
As described above, according to the second embodiment of the present invention, the paper type determination method is devised such that the transmitted light reception level and the reflected light reception level are acquired at the same timing, and the paper type is determined based on both light reception levels. As a result, various types of continuous paper P can be more accurately determined. Even when the plain paper P1 having a small thickness is used, it is not determined that the paper is out.
[0088]
In the first embodiment (see FIG. 11), as in the second embodiment, the paper type is determined based on the initial threshold value, and the level value A is set after the label paper update (S37). The level value B may be set after the marked sheet update (S41). According to this configuration, the first processing step shown in FIG. 10 can be omitted. As described above, it is possible to appropriately change the setting for the paper type determination step.
[0089]
As described above, according to the error recovery method, program, and printing apparatus of the printing apparatus of the present invention, the printing control is performed according to the detected paper type, so that the user does not need to set the paper and the stored continuous paper P is stored. Printing control suitable for the printer can be performed. In addition, since the detected paper type is continuously stored in the nonvolatile memory such as the flash ROM 250 until the paper type is updated (reset), continuous paper detection is performed every time the paper is replaced such as when the paper is out. There is no need to do. Therefore, paper is not unnecessarily wasted. In addition, after the error notification, the user can easily and quickly recover from the error by opening and closing the lid once, so that the user's usability can be greatly improved. In addition, since the power key does not need to be turned on / off at the time of error recovery, various setting information (for example, setting information such as print quality and printing speed) does not disappear.
[0090]
In addition, when the paper type is updated to the label paper P2 or the marked paper P3, the continuous paper P is cued following the update, so that the user starts printing from an appropriate position when using any continuous paper. can do. In addition, since the cueing is completed when the error is recovered, the printing operation can be resumed immediately after the cueing.
[0091]
In addition, since the error notification when it is determined that the paper is out, the error notification when it is determined that the paper is different, and other error notifications are notified by different LEDs, the user is continuously connected to the printing apparatus 10. Without checking the paper P, the contents of the error can be grasped instantly. Further, since any error can be easily restored by opening and closing the lid body 12, the usability can be further improved.
[0092]
Regardless of the above form, the sheet type detection method and error recovery processing procedure can be appropriately changed without departing from the present invention.
[0093]
【The invention's effect】
As described above, according to the error recovery method, program, and printing apparatus of the printing apparatus of the present invention, it is possible to print on a plurality of types of continuous paper, and when performing print control based on the detection result of the continuous paper, There are operations and effects that the error recovery can be performed easily and quickly while minimizing the waste of paper for detection.
