Solving Print Quality Problems
If the inside of the printer is dirty, or paper is improperly loaded, print quality maybe reduced. See the table below to troubleshoot the problem.

|
|
|
| Light or faded | If a vertical white streak or faded area appears on the page: | |||
|
| • The toner supply is low. You may be able to temporarily | |||
|
|
|
|
| extend the toner cartridge life. See “Redistributing Toner” on |
|
| AaBbCc |
|
| page 5.3. If this does not improve the print quality, install a |
|
| AaBbCc |
|
| new toner cartridge. |
|
|
|
| • The paper may not meet paper specifications (for example, | |
|
| AaBbCc |
|
| |
|
|
|
| the paper is too moist or too rough). See “Paper | |
|
| AaBbCc |
|
| Specifications” on page E.3. |

|
| • If the entire page is light, the print resolution setting is too |
|
|
|
|
| light or Toner Save Mode is on. Adjust the print resolution |
|
|
|
|
| |
|
|
|
|
| |
|
|
|
|
| and Toner Save Mode in the printer properties. See |
|
|
|
|
| page 4.22 and page 4.9 respectively. |
|
|
|
|
| • A combination of faded or smeared defects may indicate that |
|
|
|
|
| the toner cartridge needs cleaning. See “Cleaning the Inside” |
|
|
|
|
| on page 5.5. |
|
|
|
|
| • The surface of the LSU may be dirty. Clean the LSU. See |
|
|
|
|
| “Cleaning the Inside” on page 5.5. |
Toner specs | • The paper may not meet specifications (for example, the | |
AaBbCc | paper is too moist or too rough). See “Paper Specifications” | |
on page E.3. | ||
AaBbCc | • The transfer roller may be dirty. See “Cleaning the Inside” on | |
AaBbCc | page 5.5. | |
• The paper path may need cleaning. See “Cleaning the Inside” | ||
AaBbCc | ||
on page 5.5. | ||

Dropouts | If faded areas, generally rounded, occur randomly on the page: | |
AaBbCc | • A single sheet of paper may be defective. Try reprinting the | |
job. | ||
AaBbCc | • The moisture content of the paper is uneven or the paper has | |
AaBbCc | moist spots on its surface. Try a different brand of paper. See | |
“Paper Specifications” on page E.3. | ||
AaBbCc | • The paper lot is bad. The manufacturing processes can cause | |
AaBbCc | some areas to reject toner. Try a different kind or brand of | |
| paper. |
•The toner cartridge may be defective. See “Vertical repetitive defects” on the next page.
•If these steps do not correct the problems, contact a service representative.
