7.2.3 Print Quality Problems
If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See
the table below to clear the problem.
Light or faded print
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.
If this does not improve the print quality, install a new toner cartridge.
The paper may not meet paper specifications; for example, the paper is too moist or too
rough.
If the entire page is light, the print resolution setting is too low. Adjust the print resolution.
See the help screen of the printer driver.
A combination of faded or smeared defects may indicate that the toner cartridge needs
cleaning.
The surface of the LSU part inside the machine may be dirty. Clean the LSU.

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 a different brand of paper.
The paper lot is bad. The manufacturing processes can cause some areas to reject
toner. Try a different kind or brand of paper.
If these steps do not correct the problem, contact a service representative.

cartridge and install a new one.
