Service Calibrations
HP Designjet 4000/4020 Printer Series Service Manual
Only scan the Calibration Pattern in the Printer that was used
to actually print it. Using the Calibration in a different Printer
could cause it to experience media advance problems. After
scanning the Calibration Pattern, it should be discarded.
When Loading the Calibration Pattern, use the Cutter blade on
the Print Platen to align the edge of the sheet. If you follow
this advise, you will prevent the cutter from cutting a section
of the Calibration Pattern, which could cause the Calibration
to fail.
13 Load the Calibration Pattern following the instructions on the Front Panel.
Once the Calibration Pattern is loaded correctly, the following message will
be displayed on the Front Panel. Press the Enter key to continue.
14 The Printer will scan the Calibration Pattern which could take several minutes.
Once the calibration is completed successfully, the following message will be
displayed on the Front Panel. Press the
Enter key to continue.
If the Paper Advance Calibration fails for any reason, a warning message
will appear on the Front Panel. In this case, try the following:
 Check that the Calibration Pattern was not incorrectly cut (trimming the
actual pattern) during the media load process. If this is the case, perform
the Paper Advance Calibration again from step 1.
 Perform a Line Sensor Calibration (⇒ Page 5-16) and then rescan the
Calibration pattern.
 Replace the Line Sensor ⇒ Page 8-31.
 If the problem continues, replace the Media-Axis Motor ⇒ Page 8-91.
After the Paper Advance Calibration has been performed
correctly, you MUST perform the Clean Drive Roller procedure.
If this is NOT done, the Printer will not perform correctly and
could cause Print Quality problems.
Before starting the Clean Drive Roller procedure, make sure
you first load the supplied media into the Printer.
