Printhead
Maintenance

Note:
Never shake, drop, or hit the ink cartridge. This can result in the formation of
bubbles near the ink firing chambers, which will result in poor print.

4.1.2 Interconnect Pad Cleaning
If needed, the interconnect pads on the ink pen can be cleaned with the same moistened
cloth or by using a moistened Q-Tip. However, it is important to ensure that the
interconnect pad is dry before reinserting the ink pen back into the printhead (otherwise an
electrical shortage may occur resulting in permanent damage).
4.1.3 Printhead
Purging
If the printhead is inactive for an extended period of time, ink may dry in the nozzles
forming “ink plugs”. This may result in missing lines of print. When this occurs, the
cartridges should first be wiped (
). Once this is done, the ink plugs can be
forced out or purged by printing test patterns at high resolutions (i.e. 660 DPI). This
process should be repeated until the missing lines are eliminated.
