| Solving Print Quality Problems |
Problem | Solution |
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 page 4.3. If this does not improve the print quality, |
| install a new toner cartridge. |
| • The paper may not meet paper specifications (for |
| example, the paper is too moist or too rough). See “Paper |
| Specifications” on page 6.3. |
| • If the entire page is light, the print resolution setting is too |
| light or the Toner Save mode is on. Adjust the print |
| resolution and the Toner Save mode in the printer |
| properties. For details, see Software User Guide. |
•A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. See “Cleaning the Inside” on page 4.6.
•The surface of the LSU part inside the machine may be dirty. Clean the LSU. See “Cleaning the Inside” on page 4.6. Contact a service representative.
Toner specs | • The paper may not meet specifications (for example, the |
| paper is too moist or too rough). See “Paper |
| Specifications” on page 6.3. |
| • The transfer roller may be dirty. See “Cleaning the Inside” |
| on page 4.6. |
| • The paper path may need cleaning. See “Cleaning the |
| Inside” on page 4.6. |
Dropouts | If faded areas, generally rounded, occur randomly on the |
| page: |
| • A single sheet of paper may be defective. Try reprinting |
| the job. |
| • The moisture content of the paper is uneven or the paper |
| has moist spots on its surface. Try a different brand of |
| paper. See “Paper Specifications” on page 6.3. |
| • The paper lot is bad. The manufacturing processes can |
| cause 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.
