Greetings, I have Ricoh MPC3502's that are losing color quality on the printing end only. Color copies on the same machine are fine. When you do a color calibration test pattern for both copying and printing, the copy color calibration test pattern is perfect. However, the printing color calibration test patterns are light right in the middle of the pattern. We have tried everything to fix this issue firmware updates PCU units, belts etc to no avail. We can correct the issue by simply doing a factory reset. Just wondering if anyone has an idea of what this might be and a better fix other than the factory reset.
