Printhead Troubleshooting
NOTE: The Jet Test Page, which may be printed using the
Troubleshooting front panel menu and is automatically printed after
the Cleaning Page, contains a localized warning when printed on A4-
size paper. The warning message suggests that the page be re-printed
on wider (A-size) paper. This is because the outer-most jets are not
exercised when the print is made on A4-size media. However, the
warning should be ignored if the printer is not going to be used with
A-size paper. The outer-most jets are never used for A4 images, so there
is no penalty unless wider images are made.
Although printhead failures will occur, they will occur at significantly
lower rates than in the past. It is important that other parts of the
printer related to printhead operation and maintenance (cap/wipe/
purge assembly, vacuum module or tubing) be inspected and, if
necessary, replaced to avoid unnecessary printhead replacements and
service callbacks.
Table 3-1 provides the process for troubleshooting the printhead. As
you proceed through the “Action” steps listed in the table, please
check the appropriate boxes under “Look for” and “What next” to
document the troubleshooting process. If you must replace the
printhead, keep a filled-out copy of this table, with the defective
printhead and the Weak and Missing Jet stest print. The following
steps provide the details to accompany the table.
1. Check the 8-digit serial number of the printhead in the Service
Support menu or on the label on top of the printhead before
replacing it. Record the number on Line 2 of the checklist.
There are two numbers on the printhead; look at the 8-digit
number.
2. Check printhead drive voltage (Head Adjust). It is critical that
new printheads only be run at the factory default of 128. Often,
the Head Adjust has been raised on the old head to extend its
life. Adjusting it above 128 will cause the jets to fail on multi-
page jobs and increases customer ink usage.
3. Print Service Test Print 2: Weak and Missing Jets. Use this test
print to evaluate the cap/wipe/purge assembly and printhead
performance.
If you see ink mixing from one row to the next, (e.g.
Medium 46 to Clear 46) this indicates the cap/wipe/purge blade
may be damaged. If it is, install a new cap/wipe/purge
assembly.
If you see weak or missing jets, the problem could be
caused by the cap/wipe/purge assembly, the vacuum system
(tubing, air valve or pump), the printhead, or the printhead
data cable. To isolate the problem, begin by checking the
