Figure 1.
Evaluating the Prime Pattern:
To print the Prime Pattern:
1. With media loaded, from the Main Menu select Utility
Menu/Prime Menu/Prime All. A test pattern prints.
2. If the printed results are unsatisfactory perform the
cartridge maintenance procedure.
To interpret the prime test pattern (Figure 1):
The prime 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 line form a “stair step” pattern. Clogged
jets appear as missing or misdirected lines in the “stair step”
pattern. Electrically defective jets appear as solid bars.
Electrically defective jets can be automatically compensated in
certain modes. The print modes for which compensation is
available are shown clearly above the Prime.
Note: At some point there may be too many defective jets to
compensate for. When this happens, replace the cartridge with
a new cartridge.
