[Misc] Ricoh mp5503 yellow disappear on printed job

[Pixtech Frameworks]

Hi All,

A customer ricoh mpc5503 yellow appears when colour pattern is printed, but printed or photocopy jobs, yellow disappears completely.
For example a job that has Red in it only Magenta appears. I have tried all I could know changing developer, opc drum, OEM toner, it seems not to work.

Does anyone knows what the issue is??

since it's on COPY only.. have you cleaned the optics?

then run color cali on the scanner

It disappears but on copy and print.

ok DID YOU CLEAN THE OPTICS AND CALIBRATE THE SCANNER?

Done that already.
I'll upload print and copy soon.

if print is not showing what good would that do? are print pages blank?

did you run scanner calibration? I don't see how you could IF prints aren't good

By "did you run scanner calibration?" Phil means User Tools - Maintenance - Auto Color Calibration. In order for the Copy portion to run properly the optics (platen glass, lamp reflector, lens face and all mirrors) must be clean. any dust or toner haze will cause a bad read of the pattern. Run the Copy portion first. That will adjust the scanner circuitry. Then run all Print portion.

With all models this should be done anytime you have light copy or print. With the Cxx03 models Ricoh put out an internal information letter recommending that it also be done every time firmware is updated.

Calibration has been done using maintenance method. Colors are complete, but still disappear when copy or print.

So you printed test pattern in service mode all came out OK then a print job should come out OK it's strange to get good test pattern and bad copy & prints. Please upload samples

That would also cause the yellow on the color test pattern to be missing as well. It is not.

I've done auto calibration, copy and printing. But when scanning it fails and tell me to start process again. Attached are original and photocopy for more clarification.

This amazes me that all colours came out ok on colour pattern in service mode.
Attached is the colour pattern.
