If ink ejection failure or non-ejection occurs due to nozzle clogging due to dust such as paper scraps or air bubbles entering the nozzle, recording will not be performed properly.
そこで、このようなインクの吐出不良、不吐出の状態を
正常に回復するための回復機構を設けた構造の記録装置
が提案されている。Therefore, a recording apparatus has been proposed that is provided with a recovery mechanism for normally recovering from such a state of ink ejection failure or non-ejection.

内のインクを排出する構造のものが知られている。In an inkjet recording device with such a structure,
The ink inside the nozzle is suctioned under high pressure or extruded from the inside to discharge thickened ink, dust, air bubbles, etc. out of the nozzle along with the ink, thereby restoring ejection.For example, For example, a suction cap connected to a pump is fitted onto the nozzle tip,
There is known a structure in which a pump is driven to suck ink with negative pressure and discharge the ink inside the nozzle.

It is. Here, 1 is an ink cartridge that stores an ink bag 2, a waste liquid reservoir 3 is integrated with the ink cartridge 1, and a replaceable waste liquid absorber (not shown) is stored in the waste liquid reservoir 3. . 4 is an inkjet recording head, 5 is a cap portion of a recovery device that is pressed against the ejection surface of the recovery recording head 4 at the home position, and 6 is a recovery system including a suction pump (not shown) and the like.

Ink is supplied to the recording head 4 from the recording head 4, and during the recovery operation, the cap portion 5 of the recovery system 6 is pressed against the ejection surface of the recording head as shown in the figure, and the ink sucked from the recording head 4 by the drive of the recovery system 6 is The liquid is collected in the waste liquid reservoir 3 together with garbage and the like.
しかしながら、このような従来の廃液溜めを具えた液体

りする虞れがある。However, in such a conventional liquid jet recording device equipped with a waste liquid reservoir, when replacing the recording ink or regular inspection of the device, it is necessary to replace the waste liquid absorber or replace the loaded waste liquid absorber. If the ejection recovery operation is performed many times before replacing the waste liquid reservoir and an amount of ink exceeding the waste liquid reservoir capacity is discharged, the waste liquid reservoir will be damaged and the ink inside will overflow, causing damage to the inside of the device. If the ink is conductive, there is a risk that the ink may short-circuit the electrical circuit within the device and damage the electrical circuit.
特に、最近は装置の小型化に伴って廃液溜めの容量も小
さくなっているため、上述したような不都合が生じる可
能性はますます高い。In particular, as devices have become smaller in size, the capacity of waste liquid reservoirs has also become smaller, so the possibility of the above-mentioned inconvenience occurring is increasing.
また、このような問題点はインクジェット記録装置に限

The waste liquid reservoir 9 has an enclosed shape to prevent spillage due to vibration or movement, has a vapor release hole 11 in the upper part, and is made of, for example, a corrosion-resistant metal material. Preferably, as shown in FIG. 2, the waste liquid reservoir 9 is made so that the metal receiver can be separated into a tray portion 9A and a cover portion 9B made of plastic, etc.
In order to remove or receive ink scum deposited and solidified on A, the dish part 9A itself and the cover part 9B can be easily replaced individually.

６に一連の回復動作を行わせるためのドライバである。The control circuit 12 has a CPU function and serves as a recording device.
In addition to OM and RAM, it has a counter 14 and a timer 15, and in addition to controlling the recording operation by the recording head 4, it guides the recording head 4 to the home position based on predetermined conditions and presses the recovery system 6 to perform recovery operation. It can be controlled to perform. Further, the heater 10 of the waste liquid reservoir 9 is controlled on/off according to the procedure described later. 16 is a driver for causing the recovery system 6 to perform a series of recovery operations.

For example, the heater 10 is turned on for a predetermined period of time to evaporate the ink solvent in the waste liquid reservoir 9.

にする。FIG. 3A shows an example of the procedure of the control operation. In this example, the heater IO is driven depending on whether or not the ink has been discharged by the recovery system 6, and first step 51
In step S2, a non-ejection recovery signal is output to the recovery system 6 to determine whether or not a recovery operation has been performed. For example, after waiting for the operation to end, the process proceeds to step S2, where the heater 10 is turned on.
Make it. Then, in the next step S3, it is determined whether a preset time required for evaporation has elapsed, and after waiting for the predetermined time to elapse, the heater lO is turned off in step S4.
Make it.

In step 1, it is determined whether the recovery operation has been repeated a preset number of times, that is, the number of times at which the waste liquid reservoir 9 will not overflow. Proceeding to step S2, the heater 10 is turned on, and in the normal case,
This is based on the recognition that the waste liquid reservoir 9 will not become full due to the second-speed and second-speed recovery operations. Thus, in step S3,
It is determined whether enough time has elapsed to sufficiently evaporate the waste liquid discharged by the recovery operation for that number of times, and if the predetermined time has been delayed, the heater 10 is turned on in step S4.
Turn off.

タｌＯを“オフ”にする。The 30th shows yet another control operation procedure. In this example, a temperature detecting means (not shown) as a state detecting means is provided near the tray portion 9A of the receiver to control both the heating temperature and time, and step 51 is shown in FIG. 3B. Although it is the same as the example, in step S2, the temperature at which the waste liquid discharged after a predetermined number of recovery operations should be maintained and for how long it should be heated is read from the memory. Thus, in step S3, the heater IO is turned on, and in the next step S4, it is determined by the temperature detection means whether the detected temperature has reached a predetermined temperature, and after waiting for the predetermined temperature to be reached, the next step S5 Then, it is determined whether the heating time has reached a predetermined time. Then, when a predetermined period of time has elapsed, the process proceeds from step S5 to step S6, and the heater IO is turned off.
なお、以上の説明では、回復動作に関連してヒータのオ

してもよい。また、廃液溜めに、耐熱性のある液吸収体
を内装しておき、蒸発させる際にこの液吸収体を介して
蒸発させるようにすることもできるのは勿論である。In the above explanation, the on/off of the heater was controlled in connection with the recovery operation, but if a means for detecting the amount of waste liquid is provided in the waste liquid reservoir, a signal from the waste liquid detection means is used to detect, for example, the amount of waste liquid. When the amount of waste liquid reaches a predetermined amount, the heater is turned on and the heating is continued for a set time to sufficiently evaporate the amount of waste liquid. It is also possible to provide a means for detecting this, such as a humidity detecting means, so that the heater is turned off when the evaporation is completed. It is also possible, of course, to install a heat-resistant liquid absorber in the waste liquid reservoir so that the liquid can be evaporated through the liquid absorber during evaporation.
更にまた、ヒータを廃液溜めに独立して設ける代りに、

ることもできる。Furthermore, instead of installing a heater independently in the waste reservoir,
For example, heat may be supplied from a fixing heater disposed on a platen or the like as a heat source. Furthermore, by providing the waste liquid reservoir with a heater and a state detection means, the waste liquid reservoir can be made into a cartridge, thereby simplifying the configuration of the apparatus.

ければならなかったのが解消され、ランニングコストの
節減に大いに貢献することができる。As explained above, according to the present invention, the waste liquid reservoir that receives the recording waste discharged from the recovery system is provided with a heating means for evaporating the waste liquid. There is no need to pollute the surrounding area or damage the circuit due to wet fields, and to prevent this, a waste liquid sensor is installed in the waste liquid reservoir.
Even if the filling is detected, the need for frequent replacement will be eliminated, making a significant contribution to reducing running costs.
さらに制御手段により加熱手段の駆動を制御できるので
、不必要な加熱を防ぎ、装置に悪影響を与えず、効率の
よい廃液処理を行うことができる。Furthermore, since the driving of the heating means can be controlled by the control means, unnecessary heating can be prevented, and efficient waste liquid treatment can be performed without adversely affecting the apparatus.
