Pay special attention when using large-character inkjet printers, because the inkjet printers are all large characters. For the instantaneous ejection of ink, it must be sufficient, and not too much, so the ink ejection requirements It must be higher. Not only the reason for inkjet, inkjet printers also have a variety of precautions in normal use.
Large character inkjet printer (DOD ) is basically made of ink, solvent, and cleaning agent. Replacement of large-character inkjet printer consumables: The nozzle of the inkjet printer is very small (40-70 microns in diameter), and the printed characters are required to dry quickly and have high adhesion, so the requirements for ink substitutes are extremely high.
Each process of the consumables production process has strict process and quality control, and the product is formed through original inspection, purification, batching, grinding, reaction, stabilization, three-stage filtration, filling, and inspection. Developed, continuously replenish the material lost in the ink during the operation of the laser printer and repair the structural damage caused by the circulation to the ink.
The use of low-quality consumables will cause the nozzle to be re-inserted, the ink droplets are poorly charged, the printing performance is poor, the ink filter and the ink circuit are reset, and the machine parts are rusted. Consumables of different manufacturers and models are generally not universal.
Causes and solutions for other failures of large character inkjet printers (DOD )
Large character inkjet printer (DOD ) supplier: During the actual use and maintenance of large character inkjet printers (DOD ), there will be ink supply, sometimes the ink line is present, sometimes not. It is generally considered that the nozzle is blocked, but the possible possibility is Because the ink supply solenoid valve is not working properly.
For example, the ink supply solenoid valve of the inkjet printer is long open, and some are long closed. If the ink supply solenoid valve of the printer is open for a long time, it is mainly whether the voltage is sufficient, whether the spring is too hard, and whether the iron core is a card. Treatment method: check the voltage, replace the spring and the iron core (if there are no accessories, you can reduce the spring by a small section, and then extend a part. The iron core is polished with a file until it is not stuck).
The long-closed ink supply solenoid valve is generally caused by too long rubber core and iron core jamming. Treatment method: shorten the rubber core and clean the iron core.
