Dropouts | If faded areas, generally rounded, occur |
| randomly on the page: |
AaBbCc | • A single sheet of paper may be defective. |
AaBbCc | Try reprinting the job. |
• The moisture content of the paper is | |
AaBbCc | uneven or the paper has moist spots on its |
AaBbCc | surface. Try a different brand of paper. |
See "Selecting print media" on page 24. | |
AaBbCc | • The paper lot is bad. The manufacturing |
| processes can cause some areas to reject |
| toner. Try a different kind or brand of |
| paper. |
•Change the printer option and try again. Go to printer properties, click Paper tab, and set type to Thick Paper. Refer to the Software section for details.
If these steps do not correct the problem, contact a service representative.
White Spots | White spots appear on the page: |
•The paper is too rough and a lot of dirt from
the paper falls to the inner devices within the printer, which means the transfer belt may be dirty. Clean the inside of your printer. Contact a service representative.
• The paper path may need cleaning. Contact a service representative.
Vertical lines | If black vertical streaks appear on the page: |
•The drum inside the toner cartridge has probably been scratched. Remove the
toner cartridge and install a new one. See "Replacing the toner cartridge" on page 53.
If white vertical streaks appear on the page:
•The surface of the LSU part inside the
printer may be dirty. Clean the LSU, contact a service representative.
Color or Black | If the amount of background shading becomes |
background | unacceptable: |
•Change to a lighter weight paper.
See "Selecting print media" on page 24.
•Check the printer’s environment: very dry
(low humidity) or high humidity (higher than 80% RH) conditions can increase the amount of background shading.
•Remove the old toner cartridge and install
| a new one. See "Replacing the toner |
| cartridge" on page 53. |
Toner smear | • Clean the inside of the printer. |
| See "Cleaning the inside" on page 50. |
| • Check the paper type and quality. |
| See "Selecting print media" on page 24. |
| • Remove the toner cartridge and install a |
| new one. See "Replacing the toner |
| cartridge" on page 53. |
CONDITION | SUGGESTED SOLUTIONS |
Vertical repetitive | If marks repeatedly appear on the printed side |
defects | of the page at even intervals: |
| • The toner cartridge may be damaged. If a |
| repetitive mark occurs on the page, print a |
| cleaning sheet several times to clean the |
| cartridge. After the printout, if you still have |
| the same problems, remove the toner |
| cartridge and install a new one. |
| See "Replacing the toner cartridge" on |
| page 53. |
| • Parts of the printer 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.
A | • 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 the printer properties.
Misformed | • If characters are improperly formed and |
characters | producing hollow images, the paper stock |
| may be too slick. Try a different paper. |
| See "Selecting print media" on page 24. |
| • If characters are improperly formed and |
| producing a wavy effect, the scanner unit |
| may need service. For service, contact a |
| service representative. |
Page skew | • Ensure that the paper is loaded properly. |
AaBbCc | • Check the paper type and quality. |
See "Selecting print media" on page 24. | |
AaBbCc | • Ensure that the paper or other material is |
loaded correctly and the guides are not too | |
AaBbCc | tight or too loose against the paper stack. |
