Under most conditions, AutoJet jet substitution and the printer’s automated printhead service station keeps the printheads clean and operating without your intervention. Should operator cleaning of the printheads become necessary, the printer also provides several printhead-cleaning tools to accomplish this.

If you notice a decrease in print quality, one or more inkjets may be clogged. To check jet health and recover clogged jets, follow these procedures:

1.Purge

2.Print Prime Bars or Print Recover Jets Pattern

3.Map out missing jets with AutoJet or Manual Jet Mapping These procedures are explained in the following paragraphs.

The control panel displays a prompt asking you to enter the total width of the prime bar pattern you wish to print.
