Vertical repetitive | If marks repeatedly appear on the printed side |
defects | of the page at even intervals: |
• The imaging unit may be damaged. If a repetitive mark occurs on the page, run a cleaning sheet through several times to clean the cartridge; contact a service representative. After the printout, if you still have the same problems, remove the imaging unit and then, install a new one. (Page 11.4)
•Parts of the machine may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after a few more pages.
•The fusing assembly may be damaged. Contact a service representative.
Background scatter Background scatter results from bits of toner randomly distributed on the printed page.
• The paper may be too damp. Try printing
with a different batch of paper. Do not open packages of paper until necessary so that
the paper does not absorb too much
moisture.
• If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams on the reverse side. Printing on seams can cause problems.
•If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or in printer properties.
