DIMPLE
AREA
Figure 3-2. Cartridge Dimple Region.
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 isopropyl alcohol.
