Abstract

<P>PROBLEM TO BE SOLVED: To reduce disordered recording caused by wrong attachment of a tank in an inkjet recorder in which ink tanks independent for every ink color can be replaced separately. <P>SOLUTION: It is judged whether all of the tanks are set at regular positions after the tank replacement. When the tanks are not set at the regular positions, a recovery process according to a time while the wrong attachment state continues is carried out. Practically, when the tanks are set at the regular positions within a predetermined time even if the wrong attachment is generated, a normal suction recovery operation is carried out. When the predetermined time or more passes in the wrong attachment state, a suction recovery operation stronger than the normal suction recovery operation is carried out. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an ink jet recording apparatus that performs recording by discharging ink, and more particularly to a tank replacement sequence in which a plurality of ink tanks can be freely attached and detached.

  2. Description of the Related Art A recording apparatus equipped with an ink jet recording head (hereinafter referred to as an ink jet recording apparatus) that performs recording on recording paper by discharging ink from ejection ports (nozzles) arranged on a recording element is a high-density and high-speed recording operation. Is possible.

  The ink jet recording apparatus has a configuration corresponding to a specific function, a specification form, and the like of a system to which the apparatus is applied. In general, an ink jet recording apparatus includes a carriage on which a recording head and an ink tank are mounted, a transport unit that transports recording paper, and a control unit for controlling them.

  Then, the recording head for ejecting ink droplets from a plurality of ejection openings is serially scanned in the direction (main scanning direction) orthogonal to the recording paper transport direction (sub-scanning direction), while the recording paper is set to the recording width during non-recording. Intermittent conveyance (pitch feed) is performed with an equal amount. By using a recording head in which a large number of nozzles for ejecting ink are arranged in a straight line in the sub-scanning direction, the recording head scans the recording paper once, thereby recording with a width corresponding to the number of nozzles.

  The ink jet recording apparatus is low in running cost, can be made compact, and can easily cope with color image recording using multicolor ink. In particular, a line-type recording apparatus using a line-type recording unit in which a large number of ejection openings are arranged in the width direction of the recording paper can further increase the recording speed.

  For the above reasons, the ink jet recording apparatus is used as an output unit of an information processing system, for example, a printer as an output terminal of a copying machine, a facsimile, an electronic typewriter, a word processor, a workstation, or the like. It is also used as a handy or portable printer provided in personal computers, host computers, optical disk devices, video devices and the like.

  As an energy generating means for generating energy for ejecting ink, that is, a recording element of an ink jet recording apparatus, an electromechanical transducer such as a piezo element is used to generate heat by irradiating an electromagnetic wave such as a laser. There are those that discharge droplets by the action of, and those that heat the liquid by an electrothermal conversion element having a heating resistor.

  Among them, an ink jet recording type recording head that discharges liquid using thermal energy can perform high-resolution recording because the liquid discharge ports can be arranged at high density.

  An ink tank for supplying ink to the recording head is generally configured by an ink absorber, a container for inserting the ink absorber, and a lid member for sealing the container.

  The recording head includes a chip type integrated with such an ink tank and a recording head detachably coupled to the ink tank. In order to reduce the running cost, the ink tank replacement type is advantageous. The tank replacement type is a type that replaces a black tank with black ink and a color tank with three colors of yellow, magenta, and cyan, or each ink of black, yellow, magenta, and cyan. There are types that replace the tank. Recently, there are also tanks containing magenta and cyan inks with low density when performing photographic printing. The type in which the ink tank is replaced for each color has an advantage that the running cost can be suppressed because only the lost ink can be replaced.

  However, with the type that replaces the ink tank for each color, when the user replaces the tank due to running out of ink, if the wrong ink color tank is installed, recording is not performed with the correct ink color. Malfunctions.

  For this reason, a technique for preventing printing disturbance due to erroneous mounting of a tank has been proposed.

As one of the technologies, the ink color of the installed tank is discriminated, and when it is different from the tank that should be installed, a technology that performs special processing different from the case when a normal tank is installed is widely known. Yes. For example, Patent Document 1 discloses a technique for discriminating an ink color by irradiating a mounted ink tank with three types of light of red, green, and blue to determine a mounted tank type. Yes. Japanese Patent Application Laid-Open No. 2004-228561 describes a technique for detecting a tank type by installing different prisms for each ink color in a tank and optically detecting the prisms. Japanese Patent Application Laid-Open No. 2004-228561 describes a technique for determining a tank type by providing a storage element in an ink tank and reading tank type information recorded in the storage element with a recording apparatus main body.
JP 2001-88322 A Japanese Patent Laid-Open No. 2004-1282 JP 2005-119228 A

  When the tank is actually mounted incorrectly, different inks are mixed in the ink tank and the print head joint, resulting in color mixing. For this reason, even if a user who has noticed an incorrect installation after installing the wrong tank replaces it with a regular tank, the mixed color ink remains in the joint. A defect occurs in the result. In particular, when a mismounted tank is left unattended for a long time, the mixed color ink diffuses, and the influence of printing disturbance due to the mixed color ink becomes serious.

  For this reason, when tank mismounting occurs, it is necessary not only to notify the user that the tank is mismounted but to attach a regular tank, and also to properly perform a cleaning operation to remove mixed color ink. .

  However, Patent Document 1 refers to notification to the user such as sounding a buzzer or the like in the case of incorrect mounting, but there is no description regarding the subsequent recovery operation. Further, Patent Document 3 does not disclose any specific recovery operation after erroneous mounting.

  On the other hand, in Patent Document 2, it is necessary to quickly remove mixed-color ink after detection of erroneous mounting to prevent diffusion of mixed-color ink, and a configuration that always performs suction recovery after detection of erroneous mounting is disclosed. Has been. According to this technique, it is possible to prevent the diffusion of mixed color inks, but since suction recovery is always performed after erroneous mounting, a large amount of ink may be wasted. In particular, when the user immediately notices a wrong installation and installs a regular tank, even if there is little diffusion of mixed-color ink and there is no need to suck out a large amount of ink, the waste of ink is wasted because the suction recovery operation is performed. Will increase.

  The present invention has been made to solve the above-described problems of the prior art, and even when an ink tank is erroneously installed, the amount of ink wasted due to the recovery operation is not increased so much. An object of the present invention is to provide an ink jet recording apparatus capable of suppressing image deterioration due to mixed color inks.

  The present invention for solving the above problems is an inkjet recording apparatus capable of individually replacing a plurality of independent ink tanks for each ink type, a tank mounting portion for mounting the plurality of ink tanks, and after tank replacement, A determination unit that determines whether or not the ink tank of the tank mounting unit is mounted at a normal position, and a recovery that discharges ink from the recording head connected to the ink tank based on a determination result by the determination unit Recovery means for performing an operation, and the recovery means accompanies the recovery operation when the ink tank is not mounted at a regular position as compared to when the ink tank is mounted at a regular position. It is characterized by increasing the amount of ink.

  Further, the present invention provides an ink jet recording apparatus capable of individually replacing a plurality of independent ink tanks for each ink type, a tank mounting portion for mounting the plurality of ink tanks, and a tank mounting portion after the tank replacement. A determination unit that determines whether or not the mounted ink tank is erroneously mounted; a measurement unit that measures a time during which the erroneous mounting is continued when it is determined that the erroneous mounting is present; and a measurement by the measuring unit Recovery means for executing a recovery operation for discharging ink from the recording head connected to the ink tank based on the time to be recovered, and the recovery means is configured to perform the recovery operation based on the time measured by the measurement means. The content of is different.

  According to the present invention, even when the ink tank is erroneously attached, image deterioration due to the mixed color ink can be suppressed without increasing the amount of wasted ink accompanying the recovery operation.

(First embodiment)
A first embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a recording apparatus applicable to the first embodiment of the present invention, and FIG. 2 is a block diagram showing a main part of the recording apparatus shown in FIG. First, the basic configuration of the recording apparatus of the present embodiment will be described. As shown in FIGS. 1 and 2, the recording apparatus of the present embodiment is an ink jet recording apparatus, and its basic configuration itself is almost the same as that of a conventional ink jet recording apparatus. That is, a recording head 15 of an ink jet recording system that performs recording by discharging ink as a recording material onto a recording medium 9 such as recording paper, and each color (in this embodiment, cyan, magenta, yellow, black) (In this embodiment, four) ink cartridges 2a to 2d for supplying ink of the four colors. In the present embodiment, the recording head 15 also serves as a carriage, and the driving force of the driving motor 5 is transmitted by the driving belt 6 to the recording head 15 and the ink cartridges (hereinafter also referred to as “ink tanks”) 2 a to 2 d. Thus, the reciprocating scanning can be performed integrally along the guide rail 4. Each of the ink cartridges 2a to 2d can be attached to and detached from the recording head 15 independently.

  Further, the recording apparatus main body 1 is provided with a conveying means 3 including a plurality of rollers for conveying the recording medium 9 and a recovery means 13 for improving the discharge state of the recording head 15. The recovery means 13 sucks and removes the wiper blade 8 for cleaning the front surface (ejection port surface) of the recording head 15 and the foreign matter such as solidified ink, bubbles, and dust existing in the ejection port (not shown) of the recording head 15. It has a suction means 7 including a pump and a cap for this purpose.

  During the recording operation, the conveyance means 3 intermittently conveys the recording medium 9 by a pitch corresponding to one line, and the recording head 15 ejects ink onto the recording medium 9 while scanning in a direction across the recording medium 9. Doing is repeated alternately. Thereby, recording on the recording medium 9 is performed. When recording is not being performed (particularly when the recording head 15 is in the standby position (home position)), the wiper blade 8 cleans the front surface (ejection port surface) of the recording head 15 at an appropriate timing. In addition, the suction unit 7 sucks and removes foreign matter, thickened ink, and the like from an ejection port (not shown) of the recording head 15, thereby maintaining the ink ejection performance of the recording head 15.

  As shown in FIG. 2, the control circuit unit 22 is built in the recording apparatus main body 1 including the transport unit 3 and the recovery unit 13. The control circuit unit 22 includes a CPU (Central Processing Unit) 10 that controls various operations of each unit of the recording apparatus including the transport unit 3, the recovery unit 13, and the recording head 15. A storage device 12 that is a semiconductor memory such as an EEPROM (Electrically Erasable Programmable Read Only Memory) and a flash memory that can rewrite information, and a ROM (Read Only Memory) 11 that is another storage device are included. The storage device 12, which is a semiconductor memory, can retain already stored data even when the recording apparatus main body 1 itself is turned off. In the present embodiment, information such as ink cartridge identification information and ink cartridge mounting history is stored. On the other hand, the ROM 11 stores various control procedures and data. In addition, in the recording apparatus main body 1, an ink cartridge detection unit 17 that is an optical sensor or a mechanical sensor that detects the presence or absence of an ink cartridge is provided, and is connected to the CPU 10.

  In the present embodiment, as shown in FIGS. 2 and 3, the storage element 18 is provided in the recording head 15. The ink cartridges 2a to 2d are provided with storage elements 21a to 21d. Each storage element 18, 21 a to 21 d is a non-volatile memory such as an EEPROM or a dielectric memory that can retain stored contents even when power is not supplied and is electrically rewritable. As illustrated in FIG. 3, the signal lines 16 a and 16 b reaching the CPU 10 of the control circuit unit 22 through the surface of the recording head 15 are connected to the storage elements 21 a to 21 d of the ink cartridges 2 a to 2 d. ing. On the other hand, in addition to the signal lines 16a and 16b, a signal line 16c reaching the CPU 10 of the control circuit unit 22 is connected to the storage element 18 of the recording head 15. The signal lines 16a and 16b are commonly connected to the storage elements 21a to 21d of the ink cartridges 2a to 2d and the storage element 18 of the recording head 15. Each of the ink cartridges 2a to 2d and the recording head 15 are electrically connected by a contact 28, and the recording head 15 and the control circuit unit 22 are electrically connected via a flexible cable 29, and each signal line 16a. ˜16c are configured.

  FIG. 4 shows a detailed configuration of the ink cartridges 2a to 2d of the present embodiment. Each of the ink cartridges 2a to 2d includes an ink storage portion (housing) 26 that stores ink that is a recording material, a latch lever 27 that is attached to the recording head 15, and storage elements 21a to 21d that store various types of information. is doing. When the ink cartridges 2a to 2d are mounted on the recording head 15, as schematically shown in FIG. 4B, the storage elements 21a to 21d are electrically connected to the contacts 28 provided on the recording head 15. Connected.

  The storage elements 21a to 21d of the ink cartridges 2a to 2d store identification information indicating the type of the ink cartridges 2a to 2d, identification information indicating the type and color of the ink stored therein, ink consumption information, and the like. Has been. Further, the expiration date, date of manufacture, total use amount, and the like of the ink are stored. The ink cartridges stored in the storage elements 21a to 21d of the ink cartridges 2a to 2d are stored in the CPU 10 of the control circuit unit 22 of the recording apparatus main body 1 via the signal lines 16a and 16b from the storage elements 21a to 21d. Information about each of 2a to 2d is transmitted. Of course, different information is stored for each of the storage elements 21a to 21d of the ink cartridges 2a to 2d. The CPU 10 can individually know the information of each of the ink cartridges 2a to 2d by reading the information transmitted through the signal lines 16a to 16d.

  Note that the four ink cartridges (ink tanks) 2a to 2d joined to the recording head 15 contain black, cyan, magenta, and yellow ink, respectively.

  Next, a characteristic tank replacement sequence of the present embodiment will be described in detail with reference to FIG. FIG. 5 is a flowchart showing the entire processing flow of the tank replacement sequence.

  When the user opens the cover of the main body in order to replace the tank, the cover open is detected by a cover open sensor provided in the main body (step S501). When the cover open is detected, the recording apparatus moves the carriage on which the ink tank is mounted to the tank replacement position (step S502). Thereafter, in order to replace the tank, the user removes the currently installed tank and installs a new tank (step S503).

  When the tank replacement operation by the user is completed and the cover is closed, the cover is detected by the sensor. Accompanying the detection of the cover close, information unique to each tank is read out for the ink tank mounted at that time. The unique information is, as described above, identification information indicating the type and color of ink stored, ink consumption information, and the like. Then, using the information unique to each tank, it is determined whether or not all the tanks are mounted at a predetermined position (regular position) (step S504). If it is determined in step S504 that the black, cyan, magenta, and yellow ink tanks 2a to 2d are mounted at the regular positions, it is determined that the ink tank replacement has been performed normally, and the process proceeds to step S505. . In step S505, a normal suction recovery operation (normal tank replacement suction recovery operation) is performed. That is, suction is performed by the suction recovery means in order to remove bubbles that may be mixed into the head when the tank is replaced. At this time, in order to surely prevent ink ejection failure due to air bubbles, an amount of ink substantially equal to the head flow path volume is sucked.

  On the other hand, if it is determined in step S504 that the ink tank is mounted at a position different from the predetermined position, that is, a tank other than the combination of 2a black, 2b cyan, 2c magenta, and 2d yellow. Is attached, the LED provided on the recording device is blinked to notify the user that an erroneous attachment has occurred (S506). Thereafter, the user notices the erroneous mounting and replaces the tank (S507). When the erroneous mounting tank is mounted at the proper position (S508), the process proceeds to step S509.

  In step S509, a specific suction recovery operation (tank replacement suction recovery operation after erroneous mounting) is performed when erroneous mounting occurs. In this recovery operation, it is necessary to suck a larger amount of ink than in the normal suction recovery operation as shown in step S505 in order to reliably remove mixed-color ink generated at the joint between the tank and the head due to erroneous mounting. . In the present embodiment, an ink amount that is about twice the head flow path volume is sucked.

  According to the above-described configuration, a stronger recovery operation is performed when there is an incorrect mounting compared to when there is no erroneous mounting. Specifically, the ink amount accompanying the recovery operation is increased. Therefore, even when erroneous mounting occurs, it is possible to reduce printing disturbance caused by the erroneous mounting.

  In the present embodiment, in the “normal tank replacement suction recovery operation” shown in step S505, an ink amount substantially equal to the head flow path volume is suctioned, and “tank replacement suction recovery after erroneous mounting” shown in step S509. In the “operation”, an ink amount of about twice the head flow path volume is sucked, but it is not limited to this value. What is important here is the technical idea that “when there is an erroneous installation, it is necessary to increase the amount of ink associated with the recovery operation when there is an erroneous installation”. The amount of ink that accompanies the recovery operation depends on the flow path structure of the head, and may be appropriately increased or decreased in accordance with the form to be applied.

  Furthermore, when the tank is replaced normally and the time when the tank has been removed is short (for example, within 1 minute), there is almost no foam mixing, so the suction recovery operation need not be performed. Therefore, measure the time when the tank was removed at the time of tank replacement, determine whether the measurement time exceeds the predetermined time, and complete the tank replacement normally within a short time that does not exceed the predetermined time In this case, it is not necessary to perform normal tank replacement suction recovery.

(Second Embodiment)
The overall configuration of the recording apparatus and the configuration for acquiring tank information are the same as those in the first embodiment, and are therefore omitted.

  The characteristic tank replacement sequence of this embodiment will be described in detail with reference to FIG. FIG. 6 is a flowchart showing the entire flow of the tank replacement sequence.

  When the user opens the cover of the main body in order to replace the tank, the cover open sensor is detected by a cover open sensor provided in the main body (step S601). When the cover open is detected, the recording apparatus moves the carriage on which the ink tank is mounted to the tank replacement position (step S602).

  In order to replace the tank, the user removes the currently installed tank and installs a new tank (step S603). At this time, a timer T is started to measure the time since the tank was installed. The recording device has an independent timer for each tank position, and can measure time for all four positions where the tank is mounted.

  When the user's replacement work is completed and the cover is closed, that is, when the cover is detected by the sensor, information on the mounted tank is acquired by the tank information acquisition function described above. Using the information thus acquired, it is determined whether or not all the tanks are mounted at a predetermined position (regular position) (step S605). If it is determined in step S605 that the black, cyan, magenta, and yellow ink tanks are mounted at the regular positions, it is determined that the tank has been replaced normally, and the process proceeds to step S606. In step S606, a normal tank replacement suction recovery operation is performed. That is, suction is performed by the suction recovery means in order to remove bubbles that may be mixed into the head when the tank is replaced. At this time, in order to surely prevent ink ejection failure due to air bubbles, an amount of ink substantially equal to the head flow path volume is sucked.

  On the other hand, if it is determined in step S605 that the tank is mounted at a position different from the predetermined position, that is, the tank is mounted in a combination other than the combination of 2a black, 2b cyan, 2c magenta, and 2d yellow. If yes, the process proceeds to step S607. In step S607, the LED provided in the recording apparatus is blinked to notify the user that an erroneous mounting has occurred. Thereafter, as described in and after step S607, the recovery process is changed according to the time until the user notices the erroneous mounting and removes the erroneous mounting tank.

(1) “When a misplaced tank is removed within N1 (seconds)”
Incorrect mounting results in mixed color ink at the head / tank joint. However, within N1 seconds, the diffusion of the mixed color ink in the head and the tank is slight. Therefore, the normal tank replacement recovery operation described in S606 can sufficiently recover. For this reason, the process proceeds to S606.

(2) “In the case of an erroneous mounting tank removed within N1 (seconds) and within N2 (seconds)”
Incorrect mounting results in mixed color ink at the head / tank joint. By being left for N1 (seconds) or longer, the mixed color ink is diffused in the head and the tank. For this reason, there is a possibility that the diffused mixed color ink cannot be completely removed by the suction amount in the normal tank replacement recovery operation. For this reason, in step S613, suction is performed with a larger suction amount than in the normal tank replacement recovery operation. In the present embodiment, the recovery is performed with a suction amount approximately twice the volume of the flow path.

(3) “When the incorrect mounting state continues for N2 (seconds) or longer”
Incorrect mounting results in mixed color ink at the head / tank joint. The mixed color ink diffuses in the head and the tank over time. Therefore, if the erroneous mounting state continues for a long time, the mixed color ink diffuses in a wide range in the head / tank, and cannot be recovered unless a huge amount of ink is sucked. Furthermore, when mixed color ink diffuses throughout the tank, it cannot be recovered no matter how much suction is performed. For this reason, when the erroneous mounting state continues for N2 (seconds) or longer, suction recovery is performed while the tank is erroneously mounted (S614). The intent is to remove the ink in the head together with the mixed color ink, and to fill the head with the fresh ink in the misplaced tank, thereby preventing the mixed color ink from diffusing into the tank.

  Thereafter, when the regular tank is attached by the user, the suction operation is performed again, and the ink in the regular tank is filled in the head.

  A flow in which the above operations (1) to (3) can be performed is described after S607 in FIG. In this embodiment, N1 is set to 20 (seconds) and N2 is set to 120 (seconds).

  According to the above configuration, even when the tank is erroneously mounted, the suction amount and the suction timing are appropriately set according to the time during which the erroneous mounting state continues. Accordingly, it is possible to reduce printing disturbance due to erroneously mixed color inks and to reduce ink waste.

  In addition, when the tank is replaced normally and the time when the tank is removed is short (for example, within 1 minute), there is almost no mixing of bubbles, so the suction recovery operation does not have to be performed. Therefore, measure the time when the tank was removed at the time of tank replacement, determine whether the measurement time exceeds the predetermined time, and complete the tank replacement normally within a short time that does not exceed the predetermined time In this case, it is not necessary to perform normal tank replacement suction recovery. However, when erroneous mounting occurs, even if the erroneous mounting time is short, a slight amount of mixed-color ink is generated, so it is necessary to perform suction recovery. Therefore, even in the “recording apparatus that does not perform normal tank replacement suction recovery when tank replacement is performed in a short time”, it is necessary to perform suction recovery when the determination in S612 is “Y”.

(Other embodiments)
In the first and second embodiments, the suction recovery operation has been described as an example of the recovery operation, but the present invention is not limited to this. In the present invention, the preliminary discharge operation may be executed as the recovery operation, or both the suction recovery operation and the suction recovery operation may be executed.
