Note: If paper has been used which is not on the CognitiveTPG recommend paper list, resulting in a dirty printhead, the
printhead may require cleaning prior to switching back to CognitiveTPG recommended paper. See Chapter 5 for a list.
If non-recommended paper is used over an extended period, attempting to clean the printhead will have little effect
on print quality.
Do not try to clean within the printer except as noted in the A799 Service Guide, Chapter 4: Cleaning and
Maintenance.
