Troubleshooting
All pages have a black vertical line.
The print head may need maintenance. Call Technical
Support.
Light patches of print appear on the image.
Make sure the paper does not have any dents or wrinkles. It
should lie flat, and it should not have a defective or uneven
surface coating. Use recommended paper, and make sure
it does not have any obvious deformities. The printer requires
smooth paper to work properly.
Check the setting of the density dial. If the setting is too low,
raise it. See page 30.
Clean the print head. Follow the instructions on page 37.
The top margin is incorrect.
Make sure the correct margins have been set in the
software application. If not, set the margins for the top and
bottom of the page.
Make sure you are not inserting the paper into the paper
input slot with excessive force. Always insert the paper gently.
NOTE:
PCL4 automatically assumes top and bottom
margins of approximately 0.25 inch. Although the
PocketJet printer is not limited to 0.25 inch margins,
the margins are necessary to maintain compatibility
with the PCL4 printer emulation.
The image for one page requires more or
fewer sheets than you expected.
Make sure the software application or printer driver has
been set to print the same size paper that you are loading
into the printer. If the application or printer driver has been
set to print legal-size paper and you insert letter-size paper,
the image will require two sheets. Adjust the application or
printer driver settings as needed, or reduce the print image
within your application to fit on a letter-size page.
If you are using DOS “PRINT” or “COPY” commands or a DOS
application that does not send PCL printer setup information
prior to the print job, check the settings of the DIP switches
that control the default paper size. See page 26.
