| Background scatter results from bits of toner | |
|

| randomly distributed on the printed page. | |
Background | • | The paper may be too damp. Try printing | |||
| with a different batch of paper. Do not open | ||||
scatter |
| ||||
| packages of paper until necessary so that | ||||

|

|
|

|
|
|
| avoid printing over areas that have | |
|
|
|

|
|
|
| Printing on seams can cause problems. | |
|
|
|
| • | If background scatter covers the entire |

Misformed | • | If characters are improperly formed and | |||
characters |

|
|
|
| • | If characters are improperly formed and |
