Recently, a customer from one of our plastic packaging companies reported that ink leaks were often found in UV inkjet printers. Ask us how to deal with it? Today, we will share with you common reasons and solutions for ink leakage in high-resolution inkjet printers based on the experience of after-sales engineers.
The production line of this packaging company in Chengdu uses a three-nozzle UV inkjet printer, and ink leaks are the middle nozzle. The after-sales engineer found that ink leaked during the power outage, and the M3 wire on the front of the nozzle cover slipped; after replacing the nozzle solenoid valve and fixing the nozzle cover with Phillips screws on the side, the spray printing test was normal.
What are the common reasons for ink leakage from UV inkjet printer nozzles?
1. The solenoid valve of the sprinkler head is damaged;
2. The ink filter of the nozzle is not tightly sealed;
3. The ink pipes and filters are blocked due to the use of inferior ink;
4. Damage to the ink cartridge;
5. Caused by excessive ink addition;
6; The nozzle is damaged and causes leakage;
7. The fixing of the nozzle cover and nozzle becomes loose, causing ink leakage when the inkjet printer is working;
8. The machine negative pressure parameter is set incorrectly.
The inkjet printer needs to be maintained regularly. The inkjet printer is operating at high load for a long time and belongs to fragile production equipment. It is recommended to carry out regular cleaning and maintenance (if the company does not have a maintenance engineer, it is recommended to contact the manufacturer for after-sales). If ink leaks from the inkjet printer, it is recommended to promptly contact the supplier or manufacturer's after-sales service company to promptly handle the UV inkjet printer failure so as not to affect the inkjet quality and production plan.
