Print the Prime pattern as described in the next section, then align the
cartridges as described later in this guide.
Priming the ink cartridges
Before printing and at regular intervals during printing, the printer wipes the ink cartridge
jets at the service station. This function is user selectable during printing or between
prints. Still, ink cartridge jets can become clogged, especially with prolonged exposure to
the air or with disuse. Printing the Prime pattern helps to clear the jets and to check that
the ink cartridges fire properly. ENCAD recommends that you prime the cartridges daily
to ensure the best possible print quality.
The printer includes a feature called Open Jet Detection and Compensation. This feature
helps maintain optimal print quality and gives you the confidence to print long, unat-
tended jobs. During multi-pass printing, the printer will automatically compensate for jets
found to be electrically damaged. The only intervention needed is to verify that there are
no clogged jets and then choose which print mode is most appropriate for your needs.
This is by printing the Prime test pattern and then setting the print mode accordingly.
To prime the ink cartridges
1
With media loaded, press Utility/Prime.
A test pattern prints.
2
If the printed results are unsatisfactory, run the test several more times to
unclog the inkjet nozzles.
To interpret the Prime test pattern
The test pattern consists of bands of color for each cartridge and a sloping
line. Within the Prime test pattern, each jet is represented with a short
horizontal line. Together, these short horizontal lines form a "stair step"
pattern. Electrically defective jets appear as solid bars. Clogged jets appear
as gaps or misdirected lines in the "stair step" pattern. The print modes for
which compensation is available are shown clearly above the Prime.
