Ink cartridges do not fire properly
Be sure that cartridges and the service station are cleaned periodically to maintain good
print quality. (See the Maintenance Guide.)
Cartridges may wear out after extended use. Try replacing the cartridge.
Store cartridges in a sealed container at room temperature when not in use for extended
periods of time.
Make sure the protective tape is removed from the cartridges.
Remove the cartridge and reinstall it, or clean the electrical contact on the cartridge and
carrier. Be sure it is clean and dry. Be sure the cartridge is seated properly. (See the
Quick Start Guide.)
Check that ink is being fed through the delivery lines. If necessary, use the NovaPrime to
pull ink out of the nozzle plate to remove trapped air bubbles.
Be sure the ink reservoirs are not empty.
Cartridges leaking
Check that reservoirs are not overfilled.
Ensure needle assembly is tightly fastened on top of cartridge.
Ensure lines are primed and filled with ink.
Various nozzles are clogged or stop firing
Repeat prime several times.
Remove, clean, and reinstall cartridge; repeat prime. Do not use alcohol on the jet area.
Clean service station; clean cartridge again; repeat prime.
Clean cartridge electrical contacts using a cotton swab moistened with water. Dry
contact. Repeat prime. Do not use acetone or any other harsh cleaner as this may cause
damage to the flex cable.
Nozzle may have failed. Replace cartridge. Check for nozzle clogs by using the
NovaPrime on the cartridge nozzle plate.
Check to see whether spray from printing has contaminated the flex contact. Remove
the cartridge and wipe the carriage flex and cartridge flex with a cotton swab moistened
with water.
