Toner specks | • The paper may not meet specification, for |
| example, the paper may be too moist or rough |
| (See "Selecting print media" on page 2). |
| • The paper path may need cleaning (See |
| "Cleaning the inside" on page 1). |
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 "Selecting |
|
|
|
|
| print media" on page 2). |
|
|
|
|
| • The paper lot is bad. The manufacturing |
|
|
|
|
| processes can cause some areas to reject |
|
|
|
|
| |
|
|
|
|
| toner. Try a different kind or brand of paper. |
|
|
|
|
| • Change the printer option and try again. Go to |
|
|
|
|
| Printing Preferences, click Paper tab, and |
|
|
|
|
| set type to Thick (See "Opening printing |
|
|
|
|
| preferences" on page 2). |
|

|
|
|
|
| |
|
|
|
|
| paper falls to the inner devices within the |
|
|
|
|
| machine, which means the transfer belt may |
|
|
|
|
| be dirty. Clean the inside of your machine. |
|
|
|
|
| Contact a service representative. |
|
|
|

Black background If the amount of background shading becomes | ||||
|
|
|
| unacceptable: |
|
|
|
| • Change to a lighter weight paper (See |
|
|
|
| "Selecting print media" on page 2). |
|
|
|
| • Check the environmental conditions: very dry |
|
|
|
| (low humidity) or high humidity (higher than |
|
|
|
| 80% RH) conditions can increase the amount |
|
|
|
| of background shading. |
|
|
|
| • Remove the old toner cartridge and, install a |
|
|
|
| new one (See "Replacing the toner cartridge" |
|
|
|
| |
|
|
|
| on page 2). |
|
|
|
|
|
Toner smear | • Clean the inside of the machine (See "Cleaning | |||
|
|
|
| the inside" on page 1). |
|
|
|
| • Check the paper type and quality (See |
|
|
|
| "Selecting print media" on page 2). |
|
|
|
| • Remove the toner cartridge and then, install a |
|
|
|
| new one (See "Replacing the toner cartridge" |
|
|
|
| on page 2). |
|
|
|
|
|
|
|
|
|
|
Vertical repetitive | If marks repeatedly appear on the printed side of | |||
defects | the page at even intervals: | |||
|
|
|
| • The toner cartridge may be damaged. If a |
|
|
|
| repetitive mark occurs on the page, print a |
|
|
|
| cleaning sheet several times to clean the |
|
|
|
| cartridge. After the printout, if you still have the |
|
|
|
| same problems, remove the toner cartridge |
|
|
|
| and install a new one (See "Replacing the |
|
|
|
| toner cartridge" on page 2). |
|
|
|
| |
|
|
|
| • Parts of the machine may have toner on them. |
|
|
|
| If the defects occur on the back of the page, |
|
|
|
| the problem will likely correct itself after a few |
|
|
|
| more pages. |
|
|
|
| • The fusing assembly may be damaged. |
|
|
|
| Contact a service representative. |
Background | Background scatter results from bits of toner | |
scatter | randomly distributed on the printed page. | |
|
| • The paper may be too damp. Try printing with |
| A | a fresh ream 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.
