Light Print or Fade
If a vertical white streak or faded area appears on the page:
! The toner supply is low. You may be able to temporarily extend
the toner cartridge life. See Redistributing the Toner. If this does
not improve the print quality, install a new HP toner cartridge.
! The paper may not meet HP’s paper specifications (for example,
the paper is too moist or too rough). See Media Specifications.
! If the whole page is light, the print density adjustment is too light
or EconoMode may be on. Adjust the print density and
EconoMode within the software driver. See Using EconoMode or
Draft Printing. For non-Windows operating systems, this feature
is also available in HP Web JetAdmin.
Toner Specks
! The paper may not meet HP’s paper specifications (for example,
the paper is too moist or too rough). See Media Specifications.
! The transfer roller may be dirty. See Internal Cleaning Procedure.
! The paper path may need cleaning. See Engine Cleaning.
Dropouts
If faded 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 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 Media Specifications.
! The toner cartridge may be defective. See Vertical Repetitive
Defects.
! If these steps do not correct the problem, contact an HP-
authorized dealer or service representative. See HP Customer
Care (Service and Support) or Worldwide Sales and Service
Offices.
