White spots caused by fingerprints
Cause:
Fingerprints stick on paper, which changes the electrical resistance of the paper and the quality of image
transfer changes, causing white spots.
Occurrence conditions
• Black halftone images (the quality of image transfer is easily changed)
• High temperature/humidity environment
Solution:
• Wear gloves.
After setting paper on the tray, discard the top and the bottom sheets of the paper.
• Do not touch the printed areas when loading the paper.
