White Spots - Ricoh Pro C651EX Troubleshooting Manual

4.8.5 White Spots

Paper feed direction
Cause:
Paper dust on the guide board and transfer timing roller may stick to the paper and
produce white spots.
Some types of paper, such as recycled paper, roughly cut paper, and high-friction
coated paper produce a lot of paper dust, which will likely stick to the paper.
Solution:
Clean the paper feed path (dust catcher, transfer timing roller, guide board, and
paper feed roller) between the paper tray in use and the transfer unit's nip (where
the images are transferred from the intermediate transfer belt to the paper).
The paper feed paths between each paper tray and the nip are as follows:
