Symptom Action Any print quality problem The quality of the printed output is not acceptable.   Examples of
unacceptable output include light printing, streaks, splotches, random
deletions, blank pages, and so on.   See Appendix  D, “Print Quality
Problems” on page  179 for samples of print quality problems. Responses: 1.  Print a configuration page.   See “Printing the Printer Configuration Page” on page  13.   Verify that it has the same print quality problem.
If not, suspect a problem with your job. 2.  If printing is light, make sure QUALITY is not set to ECONO.   Also, try increasing the DENSITY setting to a higher value.   See
“Configuration (Config) Menu” on page  60. 3.  Make sure that the paper being used is fresh and dry and meets specifications.   See “Selecting Paper and Other Printable Material” on
page  20 for more information. 4.  Install a new toner cartridge.   Light prints may indicate that you need to replace the toner cartridge.   See “Changing the Toner Cartridge”
on page  92 for instructions on removing and replacing the toner
cartridge. If you cannot obtain a toner cartridge immediately, try the following: Ÿ   Remove the existing toner cartridge from the printer.
Ÿ   Grip it firmly, and turn it upside down a few times to spread the       toner evenly along the distribution channel.
Ÿ   Reinstall the toner cartridge. 5.  If the problem involves spots or streaks, print several test pages to clean out contamination. 6.  If the problem is with complex graphics or images and the message MRT COMPRESSION displays, try changing the PAGEPROT menu
item to ON.   This item can be individually set in specific data stream
menus (PCL Menu, PS Menu, or IPDS Menu.)   You may need more
memory SIMMs to invoke it.   See “Memory Requirements” on page  3
for information about memory requirements. 7.  If you have an EDGE-EDGE setting set to ON, set it to OFF. EDGE-EDGE can be found on the following menus: Ÿ   “PCL Menu” on page  65
Ÿ   “Coax Setup Menu” on page  78
Ÿ   “Twinax Setup Menu” on page  80
Ÿ   “IPDS Menu” on page  84 8.  If quality remains poor, consider calling for service and ask to install a new Usage Kit. 158 User’s Guide
