Troubleshooting
Solving Problems with Image Position or Content

If the Print is Distorted or Unintelligible
n The interface cable between your computer and the printer could be faulty. Try
another cable to see if the problem is corrected.
n If you have connected your computer to the parallel port on the printer, make
sure you are using a genuine HP parallel interface cable.
n If the front-panel graphics language setting is Automatic (the default), try the
other settings:
(PostScript for a PostScript file, HP-GL/2 for an HP-GL/2 file etc.) and send the
file again.
n Depending on the software, drivers and RIPs you are using with your printer,
there will be different solutions to solving this problem. Refer to the Vendor’s
User Documentation for details.
If One Image Overlays Another on the Same Sheet
n The I/O Setup / I/O Timeout setting may be too long. From the front-panel menu
decrease the setting and print again.
If Pen Settings Seem to have No Effect
n Either you have changed them in Pen settings / Define palette but forgotten to
select that palette in Pen settings / Palette,
n or you expected the software-driven pen settings but in the front-panel Pen
settings / Palette is not set to Software.
If the Printer Produces a Black and White Print When You
Expected a Color Print
n Check the front-panel Color/Mono setting, and the equivalent setting in your
software.
