HP 6p, 6MP manual Vertical Fade

Vertical Fade

If a vertical white streak or faded area appears on the page:

∙The toner supply is low. See page 4-4 to temporarily extend the toner cartridge life. If this does not improve the print quality, install a new toner cartridge.

∙The print density adjustment is too light. See page 4-2 to adjust print density.

∙EconoMode may be on. See page 4-4 to turn EconoMode off.

∙The internal mirror may need to be cleaned. See page 4-8 for the internal cleaning procedure.

∙The paper may not meet HP’s paper specifications (for example, too moist or too rough). See Appendix B for media specifications.

Dropouts

If faded-out areas, generally rounded, occur randomly on the page:

∙A single sheet of paper may be defective. Try reprinting the job.

∙The moisture content of the paper is uneven or the paper has moist spots on its surface. Try paper from a different source. See Appendix B for media specifications.

∙The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or brand of paper. See Appendix B for media specifications.

If these steps do not correct the problem, see an HP authorized dealer or service representative.

Vertical Lines

If black or white vertical streaks appear on the page:

∙The photosensitive drum inside the toner cartridge has probably been scratched. Install a new toner cartridge.

∙The internal mirror may need to be cleaned. See page 4-8 for the internal cleaning procedure.
