Solving Print Quality Problems
Problem |
| Solution |
Background scatter | Background scatter results from bits of toner 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 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 “Paper Specifications” on page A.2. |
| • | If characters are improperly formed and producing a wavy |
|
| effect, the scanner unit may need service. Verify that it |
|
| also occurs on a demo page by pressing the Demo button |
|
| on the control panel when the printer is ready. For service, |
|
| contact a service representative. |
|

Page skew | • Check the paper type and quality. See “Paper | |
|
| Specifications” on page A.2. |
| • Insure the paper or other media is loaded correctly and the | |
|
| guides are not too tight or too loose against the paper |
|
| stack. |
