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.) |

|
|
|
|
| service representative to clean the inside of |
|
|
|
|
| |
|
|
|
|
| the machine. |
|

|
|
|
| • | 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. |

| Condition | Suggested solutions |
|
| |
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.) |
|
|
| • | If characters are improperly formed and |
|
|
|
| producing a wavy effect, the scanner unit |
|
|
|
| may need service. Contact a service |
|
|
|
| representative. |

|
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. |
|
|
|
|
|
|
|
|
|
|
Curl or wave | • | Ensure that the paper is loaded properly. |
| • | Check the paper type and quality. Both high |
|
| temperature and humidity can cause paper |
|
| curl. (See "Specifications on print media" on |
|
| page 4.2.) |
| • Turn the stack of paper over in the tray. Also | |
|
| try rotating the paper 180° in the tray. |
