Medaka (White Spots) - Ricoh Pro C7500 Original Instructions Manual

Occurrence conditions:
• If the machine or toner has been left idle at high temperature (due to long vacation, etc.)
• If the machine has received strong impact
• When moving the machine
• When printing solid-fill images
• Due to the strong impact of the machine, the toner adhering to the PCDU drops into the developer
and becomes coagulated.
Solution:
1. Print a solid-fill image in each of 4 colors (cyan, magenta, black, and green) to determine
the color in which white spots appear.
• Because it is difficult to identify white spots on yellow, green is used instead of yellow.
2. Print 30 to 300 full-page, solid-fill A3 sheets for the color in which white spots appear.
3. Check to see if white spots has been resolved.
