Check the message window to see if the cassette you are
using needs more media.
Printer Will Not Duplex
If the error message
DUPLEXER ABSENT
appears in the message
window, make sure you have the optional duplexing assembly cor-
rectly installed by referring to chapter 6, “Printer Options,” in your
Ref-
erence
guide. If you have correctly installed the duplexing unit and
configured the printer from the front panel to duplex (Operator Con-
trol/Def.Duplex), but the printer continues printing simplex, you may
need additional memory allocated to the frame buffer. See chapter 3,
“Advanced Printer Features,” in this guide for additional information
on memory required for duplexing.
Print Quality Problems
Print quality problems are those related to the appearance of the
pages you print. Print quality problems include white lines on the
page, uneven blacks, and other print distortions.
First, refer to the appendix B, “Technical Specifications,” in your
Ref-
erence
guide for recommended media types. If you are using recom-
mended media and continue to have problems with the quality of your
printed pages, try this quick-check procedure:
1
Check the print density control lever on the inside of the
printer.
Change the setting and try printing another page. See chapter 5,
“Print Quality,” for information on setting the print density.
2
If the
TONER OUT
message is on, remove the toner cartridge
and gently rock it from side to side.
The toner can settle, and this procedure redistributes the toner.
Reinsert the cartridge and try printing again.

If the message remains on, replace the toner cartridge.
