Table 8 (Page 5 of 7). Troubleshooting Problems: Symptoms and Actions
Symptom Action
Poor quality shading patterns Shading patterns in your printed images are of poor quality.
Response: Make sure the QUALITY item in the CONFIG MENU is not set
to REFINE. See “Configuration (Config) Menu” on page 51. Also make
sure your printer driver or printer application is not specifying Edge
Refinement. Values set in print jobs (either by the print application or the
printer driver) override values you set at the printer.
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 C, “Solving Print
Quality Problems” on page 235 for samples of print quality problems.
Responses:
1. Print a configuration page. See “Example 1 — Printing the Printer
Configuration Page” on page 32. 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 51.
3. Make sure that the paper being used is fresh and dry and meets
specifications. See “Selecting Paper and Other Printable Material” on
page 83 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 140 for instructions on removing and replacing the toner
cartridge.
If you cannot obtain a toner cartridge immediately, try the following:
Remove the existing toner cartridge from the printer.
Grip it firmly, and rock it side to side (but not upside down) a few
times to spread the toner evenly along the distribution channel.
Reinstall the toner cartridge.
5. If the problem involves spots or streaks, print several test pages to
clean out contamination. If this does not solve the problem, then go to
“Cleaning the Printer” on page 143 for information on cleaning excess
toner from the printer.
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 “Estimating Memory Requirements”
on page 199 for information about memory requirements.
7. Check the page count. See “Machine Information Menu” on page 80.
If you have printed over 350,000 pages, 700,000 pages, and so on,
you may want to consider installing a usage kit. See Appendix D,
“Installing the Usage Kit” on page 241. for more information.
