Image formation troubleshooting
| Check the toner cartridge |
| Image formation defects are many times the result of toner cartridge problems. If there is any doubt, |
| always replace the toner cartridge before troubleshooting image defects. |
| Use the following check list to ensure that the toner cartridge is still operable. |
| l Ensure that the toner cartridge is seated properly in the cavity. |
| l Inspect the toner cartridge for remaining toner. |
| l Check the expiration date of the toner cartridge (stamped on the cartridge box). |
| l Check the toner cartridge to see if it has been disassembled or refilled. |
|
|
Note | The full weight of the toner cartridge is 26.1 oz (730 grams), and its empty weight is 22.7 oz. (640 |
| grams). |
| l Inspect the cartridge for leaking toner through worn seals. (If the drum has been manually |
| |
| rotated it may have caused internal damage and toner spills may result). |
| l Check the surface of the photosensitive drum in the cartridge to see if it has been damaged or |
| scratched. Touching the drum will contaminate the photosensitive surface and may cause |
| spotting and defects during printing. |
| l Blurred areas on the page may indicate that the drum has been exposed to light for too long. This |
| causes permanent damage to the photosensitive drum. Replace the cartridge. |
