Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet type having a recording head mounted on a carriage and moving in the width direction of recording paper, and printing an image by ejecting ink droplets onto the recording paper in accordance with print data. The present invention relates to a recording apparatus, and more particularly, to a technique for managing ink in a recording head and an ink cartridge.

[0002]

2. Description of the Related Art Ink jet recording apparatuses have been used in many printings including color printing in recent years, since noise during printing is relatively small and small dots can be formed at a high density.

[0003] Such an ink jet recording apparatus is
An ink jet recording head that receives supply of ink from an ink cartridge, and a paper feeding unit that relatively moves the recording paper with respect to the recording head, and performs recording while moving the recording head on the carriage in the width direction of the recording paper. Recording is performed by discharging ink droplets onto the paper. On the carriage, a recording head that can eject black ink and each color ink of yellow, cyan, and magenta is mounted, and not only text printing with black ink but also full-color printing is performed by changing the ejection ratio of each ink. It is possible.

In the ink jet type recording head, the ink pressurized in the pressure generating chamber is ejected from a nozzle as ink droplets onto a recording sheet to perform printing, so that the ink viscosity increases due to the evaporation of the solvent from the nozzle opening. In addition, there is a problem that printing failure occurs due to solidification of ink, adhesion of dust, and mixing of air bubbles.

[0005] For this purpose, the ink jet recording apparatus is provided with a capping means for sealing the nozzle openings of the recording head during non-printing and a cleaning device for cleaning the nozzle plate as required. This capping means not only functions as a lid for preventing drying of the ink in the nozzle openings when printing is stopped, but also when the nozzle openings are clogged, the nozzle plate is sealed with a cap member, It also has a function of sucking ink from the nozzle openings by negative pressure from the suction pump to eliminate clogging due to solidification of the ink in the nozzle openings and ink ejection failure due to air bubbles entering the ink flow path.

[0006] Forcible suction and discharge of ink to eliminate clogging of the recording head and mixing of air bubbles into the ink flow path is usually called a cleaning operation, and printing is performed after a long period of suspension of the apparatus. This is executed when restarting or when the user operates the cleaning switch to eliminate the deterioration of the quality of the recorded image. After the ink droplets are ejected by negative pressure, cleaning made of an elastic plate such as rubber is performed. This is a process involving a wiping operation of the recording head surface by a member.

[0007] The recording head also has a function of applying a drive signal unrelated to printing to eject ink droplets. This function is usually called a flushing operation. This operation is performed at regular intervals in order to recover an irregular meniscus near the opening or to prevent clogging due to thickening of ink at a nozzle opening with a small discharge amount of ink droplets during printing.

[0008]

Incidentally, this kind of recording apparatus mainly for consumer use is configured such that an ink cartridge can be removably mounted on a carriage on which a recording head is mounted, from above the carriage. Therefore, the capacity of the ink cartridge is limited, and the volume must be relatively small. When the remaining amount of ink in the cartridge is reduced to, for example, about 1/3 or less, a polymer material constituting the outer shell of the cartridge,
The relative volatilization amount of the ink solvent from the air communication hole increases, and the viscosity of the ink itself in the cartridge sharply increases as shown in FIG. For this reason, there is a problem that a printing failure occurs within a short time despite the execution of the timer cleaning and the flushing performed after the power supply to the apparatus is turned on.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the purpose of, for example, selecting an appropriate amount of ink in accordance with the remaining amount of ink in an ink cartridge and other causes of thickening of ink. An object of the present invention is to provide an ink jet recording apparatus capable of guaranteeing a highly reliable printing operation by executing a discharging process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an ink jet recording apparatus according to the present invention will be described based on an embodiment shown in the drawings. FIG. 1 shows an overall configuration of a recording apparatus main body to which the present invention is applied. In the figure, reference numeral 1 denotes a carriage, which is configured to be guided by a guide member 4 and reciprocate in the axial direction of a platen 5 by a driving force from a carriage motor 3 via a timing belt 2. . On the surface of the carriage 1 facing the recording paper 6, a recording head 7 for black ink is mounted on the printing area side (left side in the figure), and a recording head 8 for color printing is mounted on the non-printing area side. In addition, it is configured such that ink droplets can be ejected to the recording paper 6 by receiving supply of ink from the black ink cartridge 9 and the color ink cartridge 10 mounted on the carriage 1.

A capping device 13 is disposed in a non-printing area (right side in the figure) of the recording device. The capping device 13 includes a cap member 14 for sealing the recording head 7 for black ink, and a color ink. A cap member 15 for sealing the recording head 8 is mounted on the same slider. Each of the cap members 14 and 15 has a size capable of sealing the nozzle forming surfaces of the recording heads 7 and 8 in one space, and is provided in a pump unit 18 including two suction pumps 16 and 17 that can be driven independently. Connected via a tube.

With such a configuration, each cap member 1
4 and 15 receive the ink droplets facing the recording heads 7 and 8 with a certain gap at the time of flushing, and seal the nozzle forming surfaces of the recording heads 7 and 8 during the idle period of the apparatus. At the time of the ejection capacity recovery operation, the ink can be forcibly discharged from the recording heads 7 and 8 by receiving the supply of the negative pressure from the pump unit 18. In the vicinity of the capping device 13, a wiping member 19 made of an elastic plate such as rubber is disposed.
Is configured to perform a wiping operation of wiping the nozzle forming surface of the recording head when the... Reciprocates toward the capping device 13 side.

The carriage 1 is provided with cartridge detectors 11 and 12 for generating a detection signal when the black ink cartridge 9 and the color ink cartridge 10 are mounted.

FIG. 2 is a block diagram showing a configuration of a control circuit mounted in the above-described recording apparatus. In FIG. 2, the same reference numerals as those in FIG. 1 denote the same parts, and a description thereof will be omitted. The print control unit 20 generates bitmap data based on print data from the host computer, generates a drive signal by the head drive unit 21 based on the data, and causes the recording heads 7 and 8 to eject ink droplets. Things.

The pump driving means 22 is operated by the suction pump 1 based on the suction intensity, suction time, and suction interval drive signals calculated and generated by the cleaning control means 27 described later.
6 and 17 are driven. The power detection means 23 detects whether power is supplied to the apparatus via the power switch SW, and outputs a signal when the power is turned on / off.

Further, the pause timer 24 starts timing when the power is turned off, and stops the timing operation when the power is turned on, so that the recording heads 7 and 8 are continuously operated by the cap device 13. This is to detect the time when the device is sealed. In other words, the pause timer 24 constitutes a post-cleaning elapsed time measuring unit that substantially manages the elapsed time after the cleaning is performed.

The flushing control means 25 prevents the clogging after the carriage 1 is evacuated to the flushing position, usually the capping position by the print control means 20 when the printing operation is continued by the print timer 26 for a predetermined time. In order to eliminate clogging, control is performed so that a predetermined number of ink droplets are ejected from all nozzle openings of each of the recording heads 7 and 8.

The cleaning controller 27 counts a predetermined time when a signal is input from an externally operable cleaning switch CL, when a new ink cartridge 9 or 10 is mounted, or when the power is turned on. In the case where the recording heads 7 and 8 are sealed by the capping device 13, a signal is output to the pump driving means 22 to operate the pumps 16 and 17 for the time set in the suction timer 28. It is.

The ink consumption calculating means 29 reads out the ink consumption stored in a consumption storage means 30, which will be described later, when the power supply detecting means 23 detects that the power is turned on. It has a function of counting the number of ink droplets ejected by the flushing operation, and multiplying this by the amount of ink per droplet stored in the count setting means 31 to calculate the amount of ink. And
When the suction command is output to the pump driving unit 22, the operation is performed so that the amount of ink discharged from the recording heads 7 and 8 is integrated.

The ink consumption calculating means 29 stores the calculated ink consumption in the consumption storage means 30 when the power supply detecting means 23 detects the power-off command, and detects the ink cartridge attachment / detachment detecting means. When the replacement of the ink cartridges 9 and 10 is detected by the detection unit 32 and a signal is output from the reset unit 33, the data of the storage unit 30 is reset.

The ink remaining amount judging means 34 calculates the ink remaining amount, which is the difference between the ink capacities of the cartridges 9 and 10 and the ink consumption calculated by the ink consumption calculating means 29, and sends it to the cleaning control means 27. A control signal is output and data relating to the remaining amount of ink is displayed on display means 35.
, And the remaining amount of ink is visually displayed.

Ink cartridge attachment / detachment detecting means 3
2 sends a signal to the elapsed time after cartridge replacement measuring means 36, and the measuring means 36
It manages the time elapsed since the replacement of the 10. Then, the data of the elapsed time is sent to the cleaning control means 27.

Next, the operation of the control circuit configured as described above and shown in FIG. 2 will be described with reference to the flowchart shown in FIG. First, in step S11, when it is determined that the power switch SW of the apparatus is turned on, in step S12, the cleaning control unit 27 detects a pause time based on data from the pause timer 24,
The pause timer 24 is reset, and the remaining ink levels of the cartridges 9 and 10 are detected based on the data from the remaining ink level determining means 34.

Subsequently, in step S13, the cleaning control unit 27 sends the suction amount corresponding to the remaining amount of ink in each of the ink cartridges 9, 10 and the number of ink droplets to be ejected by flushing to the suction timer 28 and the flushing control unit 25, respectively. The flushing control means 25 sets the amount of ink per ink droplet to be ejected at the time of flushing or printing at step S14.

If the pause time determined by the pause timer 24 exceeds the reference value in this state, step S
15, the suction amount set in the suction timer 28,
That is, the pumps 16 and 17 are operated by the pump driving means 22 based on the suction time. In this case, since the pause time is compared with the reference value and determined, it is possible to prevent a suction operation due to turning off and on the power switch SW in a short time due to an erroneous operation or the like, thereby preventing waste of ink and a decrease in throughput.

The pump driving means 22 corresponds to the remaining amount of ink in the ink cartridges 9 and 10, that is, when the remaining amount of ink is large as shown by the curve A in FIG. When the amount is small, a relatively large amount of ink is sucked from the recording heads 7 and 8.

In this case, when the remaining amount of the ink is low and the ink in the ink cartridge is thickened, the recording head 7 filled with the ink from the cartridge may be used.
The ink at the nozzle opening of No. 8 has further thickened, which is often unsuitable for printing. Alternatively, in many cases, a region that causes a defective ejection of ink droplets in a short time after the start of printing has progressed deep from the nozzle opening. Therefore, the ink cartridges 9 and 1 with less degree of thickening
By sucking a large amount of ink from 0 and discharging it, it is possible to save a decrease in the discharge function of the recording head.

When the ink suction operation is completed, the cleaning control unit 27 sends a flushing drive signal to the recording heads 7 and 8 by the flushing control unit 25.
The voltage is applied to the recording heads 7 and 8 according to the remaining amount of ink.
That is, as shown by the curve B in FIG. 4, the recording heads 7 and 8 transmit a small number of pulses when the amount of ink remaining in the ink cartridges 9 and 10 is large, and a large number of pulses when the amount of ink remaining is small. Is applied.

Note that the recording heads 7, 8
The driving signal to be applied is set at a high voltage level so that the pressure generating chamber can be strongly contracted and greatly contracted as compared with the driving signal at the time of printing. The amount of ink discharged from the recording heads 7 and 8 by the suction and flushing operations of the ink is calculated by the consumption amount calculating means 29.
And is stored in the consumption storage means 30.

If it is determined in step S16 that the printing has been started, the process proceeds to step S17.
The consumption calculating means 29 counts the total number of dots for one pass, and in step S18 multiplies this by the amount of ink per drop to calculate and add the amount of ink consumed by printing for one pass.

The printing operation continues for a predetermined time and the printing timer 2
When the time is up for 6, it is determined in step S19 that periodic flushing is necessary. In this case, the process proceeds to step S20, where the printing operation is interrupted, the carriage 1 is moved to the flushing position, and the flushing process is executed. Then, the ink amount is added and stored in the ink consumption amount storage unit 30.

After the flushing process, it is determined in step S21 whether or not print data exists. If it is determined that print data does exist, the process returns to step S17, and the same steps as above are repeated to continue printing. .

If it is determined in step S21 that all the print data has been completed, the process proceeds to step S2.
Then, it is determined whether or not the power switch SW is operated and the power-off is commanded. If it is determined in step S22 that the power-off command has been issued, the cleaning control unit 27 starts the pause timer 24.

Then, in step S23, the carriage 1 is moved to the capping position and the recording heads 8, 9 are moved.
Is sealed with cap members 14 and 15 to execute power-off processing.

In the above-described control sequence, the thickened ink is discharged by using both the suction by the pump and the flushing in accordance with the remaining amount of ink in the ink cartridge. May be used depending on the length of the key. That is, in a short rest state after ink suction, the ejection capability of the recording head can be recovered by flushing. According to this, since a time-consuming step such as a capping operation is not performed, the throughput can be improved.

In addition to the above-described control mode, the amount of ink discharged may be controlled based on the elapsed time from the execution of the cleaning obtained by the pause timer 24. In other words, when the elapsed time after the cleaning (ink suction operation) is performed for a long time, the viscosity of the ink in the ink supply path from the cartridge and the ink in the recording head increases.

Therefore, by adjusting the amount of ink suction and / or flushing as the elapsed time increases, a relatively large amount of thickened ink in the ink supply path and the recording head can be removed. As a result, a reliable printing operation can be ensured thereafter.

Further, the ink discharge amount may be controlled based on the elapsed time after the replacement of the cartridge obtained by the elapsed time after the replacement of the cartridge 36. That is, when the elapsed time after the replacement of the cartridge is long, the viscosity of the ink in the cartridge increases. In addition, as described above, the ink at the nozzle openings of the recording heads 7 and 8 in which the ink is filled from this cartridge is further thickened, and the ink droplets are ejected in a short time after the start of printing. Is advanced from the nozzle opening to the depth.

Therefore, the ink suction amount and / or the flushing amount are adjusted so as to increase as the elapsed time after the replacement of the cartridge becomes longer, so that the ink from the cartridge having a relatively small degree of viscosity increase can be obtained. Can be exchanged, and a highly reliable printing operation can be similarly guaranteed thereafter.

Further, as described above,
The suction and flushing operations by the pump may be performed by using the data of the elapsed time after the cleaning and the elapsed time after the cartridge replacement alone, but the ink suction amount is determined by using the two data in combination. The flushing amount may be determined, or the three data may be combined and operated to perform the suction and flushing operations by the pump.

In the above control sequence, the total amount of ink to be discharged by flushing is controlled by the number of ink droplets.
It is apparent that the same effect is obtained even if the control is performed by adjusting the amount of ink constituting one ink droplet.

As shown in the above-described embodiment,
In an ink jet recording apparatus equipped with a black ink cartridge and a color ink cartridge, the remaining amount of ink, the amount of ink after cleaning, By managing the elapsed time and the elapsed time after replacement of the cartridge, it is possible to obtain a practically satisfactory discharge capacity recovery operation, thereby simplifying the configuration of the control system.

Further, in the above-described control sequence, description has been made by taking an example of a recording apparatus in which an ink cartridge is mounted on a carriage. However, the ink cartridge is housed in a box, and is connected to a recording head via a flow path such as a tube. Obviously, the same effect is achieved even when applied to a recording apparatus that supplies ink.

[0057]

As is clear from the above description, according to the ink jet recording apparatus of the present invention, data such as the remaining amount of ink, the elapsed time after cleaning, and the elapsed time after replacement of the cartridge are used. Since the ink discharge amount in the ink suction operation and the flushing operation from the recording head is controlled, the appropriate ink discharge amount can always be controlled in accordance with the degree of ink thickening, and the printing operation after processing is performed. Can be improved in reliability.

Further, since the amount of discharged ink is controlled in accordance with the degree of thickening of the ink, waste of the ink can be avoided and the burden such as running cost can be reduced.
