Nozzle condition becomes poor due to the foreign substances stuck on
the surface of the Head.
Cleaning the head with Wiper is not performed efficiently and it cannot
remove the foreign substances stuck on the surface of the Head.
If the ink is not flowed down through the Cap, the head cleaning does
not work efficiently. As a result, the condition of head nozzle is not
improved by the head cleaning. If the head is not sealed by the cap, the
head will become dry and clogged.
Generally, we do not recommend to wipe the surface of Head with a
cleaning stick. Howerver, it's worth trying cleaning before replacing the
Head. Soak the cleaning stick in cleaning liquid fully, and then tap and
scrub the surface of Head with it.
When the machine keeps printing with ink cartridge almost empty, the
negative pressure delivered in the ink tube causes the improper ink
supplying and the head cannot fire the ink correctly.
If there is a bad communication between the Head and the Main Board,
the signal is not sent 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. And, the cable which has been conneted and
disconnected several times may have a damaged terminal.
If the Head is not capped correctly, the Head dries and it may cause the
Head nozzle clogging.
When air bubbles come inside the Ink line, the Head does not fire the
Ink temporarily. 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 disappear.
The Pump cannot deliver the ink properly. Therefore, the Head may not
fire the Ink.
The F1 Fuses are for C and M, the F2 Fuses are for Y and K, and the
F3 Fuses are for Lc and Lm. If the C and M Heads do not fire the Ink at
all, the F1 Fuse may be defective. If the Y and K Heads do not, the F2
Fuse may be defective. If the Lc and Lm Heads do not, the F3 Fuse
may be defective.
There might be a problem with the other devices on the Head Board if
the Fuses are not defective.
