Nozzle clogs cannot be cleared
o
Is cleaning being performed regularly?
If lint or dust adheres to the area around the print head, caps (photo 1), wiper (photo 2), or flushing pad, nozzle clogs may occur
during printing. Moreover, if the lint or dust is left adhered, nozzle clogs cannot be cleared even after repeated head cleaning.
Also, as shown in photo (3), if a film of ink has adhered, capping fails, causing a printing failure.
Clean the affected area periodically.
See “Regular Cleaning” on page 137.
o
Replace consumables.
If the problem persists after
Head Cleaning
has been performed several times or regular cleaning has been performed, the
wipers or wiper cleaners may be worn or deteriorated. We recommend that you replace them when the following symptoms
are detected.
Wiper: The wiper edge remains rough even after stains were wiped off using the clean-room wipe. Otherwise, the wiper is
cracked.
Wiper cleaner: A film of ink has adhered to the rear surface of the absorbent section. See “Replacing the Wiper and Wiper
Cleaner” on page 168.
Flushing pad: Ink has adhered to the surface, and lint or dust cannot be removed. See “Replacing the Flushing Pad” on page
172.
