1. What is the cause of the failure of the printer's recovery tube?
The root cause is that the recycling sensor does not detect if there is ink in the recovery tube. The specific reasons may be:
The ink line is not in the right position, and the ink line is not injected into the recovery tube. Possible causes: a. The ink line position is not aligned; b. The nozzle is blocked
Inkjet machine recovery tube fault inspection and treatment method: check the ink line position, if the deviation is very strong (the ink line is not perpendicular to the nozzle plane, the angle is very large), indicating that the nozzle is blocked, the printer cleaning method after the nozzle is blocked; A little bit, you can adjust the ink line position.
Second, the recovery pipeline negative pressure (recovery power) is not enough, or too small
Possible causes: a. There is a leak in the recovery line. b. Recycling pipeline plugging. c. Recycling pump plugging or damage.
Inspection and treatment method: Remove the recovery filter and rinse it with the cleaning solution. See if you can flow out of the recovery tube. If it can't flow out, the pipeline is blocked. It can be rinsed from the side of the recovery tube. If it can flow out, install the recycling filter. Check all connections in the recovery line for leaks. If there is no air leak, the pump may be blocked or damaged. It is recommended to contact the printer supplier engineer for repair.
