Fujitsu DL3860 platen-gap error: Troubleshooting guide
The Fujitsu DL3860 platen-gap error occurs when the printer's distance sensor fails to detect the correct platen position. This often happens when the paper thickness lever does not match the inserted media thickness. Properly configuring this lever usually clears the message immediately.
Common causes
- 1Incorrect paper thickness lever setting.
- 2Dust accumulation on the platen sensor.
- 3Mechanical misalignment of the carriage.
- 4Gear wear due to heavy usage.
