Symptom Parallel attachment printing problems Action Make sure your printer driver is installed and connected to the correct port. Poor quality shading patterns Any print quality problem Blank pages, double sheet feeds Also, make sure you use properly shielded and grounded cables and connectors (IBM part number 63H2804 or its equivalent) that are no more than ten feet (3 meters) in length. Responses: 1. Make sure the QUALITY item in the Config Menu is set to REFINE. See "Configuration (Config) Menu" on page 102. Also make sure your printer driver or printer application specifies Edge Refinement. Values set in print jobs (either by the print application or the printer driver) override values you set at the printer. 2. Try increasing the print density if shading is too light. If shading is too dark, try decreasing print density. See "Adjusting Print Density" on page 30. 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 B. Print Quality Problems" on page 225 for a quality-check procedure and samples of print quality problems. Responses: 1. If all sheets are blank, the toner supply could be low without the toner sensor detecting it. Replace the toner cartridge. See "Changing the Toner Cartridge" on page 144 for instructions on removing and replacing the toner cartridge. 2. Random blank pages during a print job can be caused by multiple sheets of paper being fed through the machine simultaneously. Turn the paper over and feed from the other edge or reload the paper tray with fresh, dry paper. Fan the paper before loading it. If the problem still exists with the new toner cartridge installed, consider replacing the usage kit. See "Changing the Usage Kit" on page 152. Appendix A. Troubleshooting 221
