Checking the Platen
The gap test prints a table of printhead gap values measured across and
around the surface of the platen. From this table, you can verify platen
parallelism and identify flaws, such as lumps, dents, or cracks, in the
surface of the platen.
Before you run the test, make sure that paper is loaded in the printer. On
wide-carriage models, load paper that is at least 14 inches (35.5 cm)
wide. On narrow-carriage models, load paper that is at least 8.5 inches
(21.6 cm) wide.
Then, display the TEST parameter on the
Setup menu and select Gap.
When you release the Alt button, the printer will begin moving the carriage
to various locations across the platen. At each location, the printhead will
re-gap automatically. After measuring printhead gaps across the platen,
the printer will print out the gap values. Then, the platen will rotate slightly
and the process will repeat. After printing about 20 lines of gap values,
press the Ready button to terminate the test. The Setup menu will
reappear.
If there is a problem with platen parallelism, the printhead gap values in
each line will tend to increase or decrease linearly when read from left-
to-right. If there are flaws in the platen surface, there will be an excep-
tionally high or low gap value in the table. If you see these problems in
the test pattern, contact your Service Representative for assistance.
