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 machine, which means the transfer belt |
|
| may be dirty. Clean the inside of your |
|
| machine. 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 toner cartridge has probably been |
|
| scratched. Remove the toner cartridge and |
|
| install a new one. |
| If white vertical streaks appear on the page: | |
| • | Clean the inside of the machine. Contact a |
|
| service representative to clean the inside of |
|
| the machine. |
|
| |
Color or Black | If the amount of background shading becomes | |
background | unacceptable: | |
| • | Change to a lighter weight paper. (See |
|
| "Specifications on print media" on page 4.2.) |
| • | Check the environmental conditions: very |
|
| dry conditions (low humidity) or a high level |
|
| of humidity (higher than 80% RH) can |
|
| increase the amount of background |
|
| shading. |
| • | Remove the old toner cartridge, and then |
|
| install a new one. (See "Replacing the toner |
|
| cartridge" on page 6.4.) |
|
|
|
Toner smear | • | Clean the inside of the machine. Contact a |
|
| service representative to clean the inside of |
|
| the machine. |
| • | Check the paper type and quality. (See |
|
| "Specifications on print media" on page 4.2.) |
| • | Remove the paper transfer belt, and then |
|
| install a new one. (See "Replacing the toner |
|
| cartridge" on page 6.4.) |

| Suggested solutions |
|
| |
Vertical repetitive | If marks repeatedly appear on the printed side | |
defects | of the page at even intervals: | |
| • | Clean the inside of the machine. Contact a |
|
| service representative to clean the inside of |
|
| the machine. After cleaning the inside of the |
|
| machine, if you still have the same |
|
| problems, install a new toner cartridge of the |
|
| problem color. See "Replacing the toner |
|
| cartridge" on page 6.4. |
| • | 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. |
|
|
|
Misformed | • | If characters are improperly formed and |
characters |
| producing hollow images, the paper stock |
|
| may be too slick. Try different paper. (See |
|
| "Specifications on print media" on page 4.2.) |
|
|
|
Page skew | • | Ensure that the paper is loaded properly. |
| • | Check the paper type and quality. (See |
|
| "Specifications on print media" on page 4.2.) |
| • | Ensure that the paper or other material is |
|
| loaded correctly and the guides are not too |
|
| tight or too loose against the paper stack. |
