4-14 Manual Calibrations
If you have a calibration pattern from a recent print, you
can use it to calibrate the heads. Press
n (Cancel) and go to
the next step. Otherwise, press
B.
The printer prints a jet map test pattern for printheads 1-6.
◆ If a line segment is missing or broken, the jet listed in
the same column is out. In Fig. 4-21, jets 263 and 265 are
out.
◆ If a line segment is marked with a code letter, it has
already been detected by the software, so no further
action by you is required. This data, however, may be
requested by MacDermid ColorSpan Technical Services
(phone: 800-925-0563) to help diagnose printing
problems.
Note If this test auto-detects (marks with an E) that more
than twelve jets are missing on any one printhead,
the printhead may be improperly seated. Try reseat-
ing the printhead, and print another Jet Coverage
pattern.
7. When the calibration pattern has printed, the control panel
displays a menu with the following options:
◆ Report individual bad jets — enables you to report a
bad jet.
◆ Clear individual bad jets — enables you to clear (mark
as good) a jet.
◆ View current bad jets — lists the bad jets on a given
printhead.
