Troubleshooting. Image Problems. Regular intervals
Image problems may appear at regular intervals that depend on the circumference of certain components. The following diagram shows the possible symptoms (black or white dots at regular intervals).
| Unit | Parts | Interval * |
|---|---|---|
| PCDU | Drum | 95mm |
| Development Roller | 34mm | |
| Cleaning Roller | 30mm | |
| Charge Roller | 30mm | |
| Image Transfer | Image Transfer Belt | 750mm |
| Paper Transfer | Transfer Roller | 60mm |
| Fusing | Fusing Belt | 95mm |
* The interval may vary depending on the temperature and paper slippage.
Each LED head has 26 LED chips on board, and each chip has a line of LEDs 8mm in length. If a vertical line 8mm in width appears on the image parallel to the direction of paper feed, it may be caused by a broken LED chip. Exchange the LED head with one of the other colors to troubleshoot the symptom.
