Air bubbles tend to go into the ink line by installing and uninstalling the
ink cartridge so many times. All the air bubbles inside the lines can be
removed by performing the powerful cleaning or removing the tube
from the damper and fixing the syringe with the entry of damper, then
pulling the ink until air bubbles disappears.

Cable
If there is a bad communication between the head and the main board,
the signal does not send properly and results in not working.
If the flexible cable is fixed at a slant, it may cause the bad electrical
contact or short-circuit. If you insert and remove the flexible cable
several times, it may break the terminal.
