AaBbCc

new toner cartridge of faded color.

• The paper may not meet paper specifications (for example,

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

job.

• The moisture content of the paper is uneven or the paper has

AaBbCc

moist spots on its surface. Try a different brand of paper. See

“Paper Specifications” on page D.4.

paper.
