Piezo printers adopt micro piezoelectric inkjet technology. The whole ink system is closely connected in order to ensure the sealing among cartridges, refill tube, printhead and damper. If there is a bad seal, many problems will appear, for example, printer is ink off, the printer can’t supply the ink, the printer can’t pump ink as normal, the ink comes back to damper etc. Printer can’t pump ink is a common bug, here are some reasons:
A. The position of the capping station is not good, you can try to debug the position of the capping station.
B. The deformation or aging of the capping station core, we recommend replace capping station core (pls pay attention to the maintenance and cleaning of the capping station core)
C. The ink pump does not work well, check the line to see if there is something wrong with the connection.
D. There is something wrong with the cable connection of printhead.
E. Printhead is damaged, we suggest replace a new one.
F. There is something wrong with the adjustment of the carriage frame and it’s possible that the position of the capping station is wrong.
