Troubleshooting
226
Solution
Make sure the 2500-sheet paper
tray is fully inserted in the drawer.
Reduce the complexity of the print
job by eliminating the number and
size of fonts, the number and
complexity of images, and the
number of pages in the job.
Add printer memory or a hard disk
option.
Set Print Timeout to a higher value
from the Setup Menu.
If appears on the
Replace Toner
display, replace the toner cartridge.
Refer to the User's Reference or the
documentation that ships with your
supplies for detailed information.
If no message is displayed and you
just inserted a new toner cartridge,
the printer may be transporting toner
into the photoconductor cartridge.
The motor noises should cease in
three minutes or less.
Turn the printer off, wait about 10
seconds, and turn the printer back
on.
Turn the printer off and check the
connection between the option and
the printer. Refer to the Setup Guide
for complete installation instructions.
Your printer driver may not automat-
ically recognize that an option is
attached to your printer. Open the
driver and verify that all the printer
configuration settings are correct.
