Troubleshooting. Image Quality Problems
| Problem | Cause / Solution |
|---|---|
| Blurred or too light | • AIO is out of toner. Refill or replace the AIO. • The polygon mirror of the laser unit is dirty. • Adjust the image density. • Paper is damp. Use paper that has been stored properly. • If you enable [Toner Saving], printing is generally less dense. User Tools > System Settings >Toner Saving: Off Printer Driver > Print Quality > Toner Saving: Off • Toner is almost depleted. Replace the print cartridge. • Condensation may have collected. If rapid change in temperature or humidity occurs, use this machine only after it has acclimatized. |
| Dirty or too dark | • Drum life ended. Replace the AIO. • Image density is too high. Adjust the image density. • Toner on the printed surface is not dry. Do not touch printed surfaces immediately after copying. Remove freshly printed sheets one by one, taking care not to touch printed areas. • The exposure glass or ADF is dirty. |
| Dirty background | • Drum life ended or waste toner tank full. Replace the AIO. • Adjust with “Charge Bias” in the Maintenance Mode. |
| Vertical black lines | • The stripper pawls of the fusing unit are dirty. • The exposure glass or ADF is dirty. • Replace the print cartridge. |
| Vertical White lines | • The exposure glass or ADF is dirty. • Toner is almost depleted. Replace the print cartridge. |
| Horizontal black lines | Humidity level surrounding the machine may be too low. Refer to "Dark lines in halftone areas at 75mm Intervals". |
| A moire pattern is produced. | The original probably has heavily lined or dotted areas. Switching the setting for image quality between [Photo] and [Mixed] may eliminate the moire pattern. |
| Insufficient fusing | Check the levers for printing on envelopes inside the rear cover. Pull up the levers. |
| Dark lines in halftone area | Might appear at 75 mm intervals when the machine is operating in a room where the humidity is very low. (The low humidity causes variation in light sensitivity across the surface of the drum.) Selecting [On] for [Low Humidity Mode] under [System Settings] (User Tools) may help to prevent these lines from appearing. When the humidity mode setting is enabled, the drum is rotated slightly every 15 minutes. This keeps the light sensitivity constant across the entire surface of the drum. |
