How to Avoid Damage to the Printhead in the Printing Process of UV Printers

For inkjet printing equipment, the printhead is a critical factor in the maintenance of equipment and normal print output, and because of the price of foreign imports is not expensive, a little carelessness may cause damage to bear huge costs, so master the basic knowledge of UV printer printheads for production and processing benefit a lot.

Listed below are three common initiatives that directly or indirectly affect the state of the UV printer printheads.

A. Power supply

UV printer in the process of power, you may need to disassembly, installation, cleaning operations, for your safety and stability of the equipment, please first power off and then effective operation, do not operate in the normal work of a wide range of operations and replacements, will have an impact on the UV printer control and ink delivery system, indirectly leading to the stability of the UV printer printheads to reduce and block the head burning situation.

In the cleaning process, first power off and then carefully cleaned, do not splash ink cleaning fluid to the circuit board and precision electronic parts, so as not to cause a short circuit in the line endangering the UV printer printhead.

Second, UV ink and cleaning fluid

UV printers using UV ink and cleaning fluid is very “picky”, the quality of the ink easy to solidify the ink road to trigger a blocking crisis; different kinds of ink brands mixed will lead to poor print image effects, the impact of color difference does not meet the printing needs; poor quality cleaning fluid will not only clean the inkjet ink, but also long corrosion of the nozzle . So choose UV ink and cleaning fluid try to choose the manufacturer matching ink, after-sales maintenance to protect some.

Third, the cleaning method

UV printer as a more mature digital printing equipment, there is a set of maintenance UV printer nozzle cleaning system is generally sufficient, but sometimes need to manually clean the operation to complement play a full range of protective measures. UV printer automatic cleaning process, try to ensure that a day cleaning, do not frequent cleaning and prolonged stagnation, so as not to cause excessive corrosion and ink solidification phenomenon.

UV printer nozzle clogging manual cleaning process, do not use ultrasonic and high-pressure water gun cleaning method, will have a certain impact on the nozzle, it is recommended that the use of syringes slowly rinse, can minimize nozzle wear.

Here we recommend two UV printer printhead maintenance tips

① Try to choose the manufacturer’s original printheads, small-format UV9060 printers choose G5i or Epson XP600 printheads, large-format UV printers choose Ricoh G5 and other industrial printheads.

② UV printer installation training process, there are nozzle maintenance cleaning steps, you need to carefully understand and practice to extend the life of the nozzle.
