3-6 Maintenance
NovaJet 500/630/700 Series Service Manual
The cartridge dimple area can easily be contaminated by oils and dirt on
fingers and hands or ink spilled onto them. This causes the cartridges
to not receive some of the electrical signals for a proper firing of the jets.
This can be seen as a misfiring of the cartridge.
NOTE
Care should be used when handling the cartridges. Avoid
touching the cartridges on the dimple area or on the inkjet
holes on the bottom. The oils and dirt on fingers and
hands can contaminate the area and result in misfiring
of the inkjets.
Clean the cartridge dimple area by gently dabbing the area with a lint
free cloth or cotton swab saturated with NovaKlean™.
Be sure to clean the yellow cartridge because it is not readily apparent
that it is dirty. The yellow ink is hard to see and could be overlooked.
Follow this up by gently dabbing the jet plate area on the bottom of the
cartridge.
