Gray background | If the amount of background shading becomes unacceptable, the | ||
|
|
| procedures below may fix the problem. |

| • Use lighter weight pages. See page 21. |
| AaBbCc |
| • Check the machine’s environment. Very dry (low humidity) or humid |
| AaBbCc |
| (higher than 80% RH) conditions can increase the amount of background |
|
| shading. | |

|
|
| • Check the paper type and quality. See page 21. |

Repetitive defects | If marks repeatedly appear on the printed side of the page at even intervals: | |||||
|
|
|
|
|
| • The toner cartridge may be damaged. If a repetitive mark occurs on the |
|
| AaBbCc |
|
| page, print a cleaning sheet several times to clean the cartridge. See | |
|
| AaBbCc |
|
|
| page 68. |
|
| AaBbCc |
|
| After the printout, if you still have the same problems, install a new toner | |
|
| AaBbCc |
|
|
| cartridge. See page 65. |
|
|
|
| • Parts of the machine may have toner on them. If the defects occur on the | ||
|
| AaBbCc |
|
| ||
|
|
|
|
|
| back of the page, the problem will likely correct itself after a few more |
|
|
|
|
|
| pages. |

Background scatter | Background scatter results from bits of toner distributed on the printed | |||||

| • 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 program or the printer |
|

|
|
| properties. |

Misformed characters | • If characters are improperly formed and producing hollow images, the | |||||
|
|
|
|
|
| paper stock may be too slick. Try a different paper. See page 21. |

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