Printing quality problems
If the inside of the machine is dirty or paper has been loaded improperly, you may notice a reduction in print quality. See the table below to clear the problem.
| Condition | Suggested solutions |
|
| |
Light or faded print 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. If this does not improve the print quality, install a new toner cartridge.
• The paper may not meet paper specifications; for example, the paper may be too moist or rough. (Page 4.3)
•If the entire page is light, the print resolution setting is too low or the toner save mode is on. Adjust the print resolution and turn the toner save mode off. See the help screen of the printer driver and refer to Software section, respectively.
•A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning. Contact a service representative.
•The surface of the LSU part inside the machine may be dirty. Clean the LSU, contact a service representative.
Toner specks | • | The paper may not meet specifications; for |
|
| example, the paper may be too moist or |
|
| rough. (Page 4.3) |
| • | The transfer roller may be dirty. Clean the |
|
| inside of your machine. Contact a service |
|
| representative. |
| • | The paper path may need cleaning. Contact |
|
| a service representative. |
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. (Page 4.3)
• The paper lot is bad. The manufacturing processes can cause some areas to reject toner. Try a different kind or brand of paper.
•If these steps do not correct the problem, contact a service representative.

|
| machine may be dirty. Clean the LSU. |

Gray background | If the amount of background shading becomes | |
| unacceptable: | |
| • | Change to a lighter weight paper. (Page 4.3) |
| • | Check the environmental conditions: very |
|
| dry conditions (low humidity) or a high level |
|
| of humidity (higher than 80% RH) can |
|

|
| shading. |
