Map Out Missing Jets
If the Prime Bars reveal blank lines after a Purge, the corre-
sponding jets should be mapped out. When all missing jets have
been substituted, printed output will appear as if all jets are
working.
You can map jets out temporarily (“soft bad jets”) or permanently
(“hard bad jets”). For instructions, see “AutoJet” on page 4-3 or
“Manual Jet Mapping” on page 4-18.
When AutoJet detects a missing jet, it attempts to replace it with
a working jet on the same or another printhead (in Production
and High Quality modes). In this way, printing occurs with all jets
for maximum quality.
Optionally, you can print a Jet-Out Lines pattern to see which
jets have been subsitituted.
1. From the control panel Front Page screen, press the Cali-
brate key.
The Calibrate menu appears.
2. Press Manual Calibrations .
The Manual Calibrations menu appears.
3. Press Print Jet-Out Lines.
The Jet-Out Lines pattern prints. Substituted jets are marked
with a black square.
