You need to fix your saturation first before the sensors can read the patches correctly.

Re: Color problem ricoh mp c2050

i would pull fuser,all drums and transfer belt unit and clean the sensors below fuser unit and clean all laser slit glasses..
maybe run a forced toner and the try calibration

Re: Color problem ricoh mp c2050

All the above but sensors are below ITB.

First thing to do is properly clean the ID sensor assembly. I have that alone pull the color alignment back.

+1...don't be afraid of replacing the ID sensor board itself.

+2. I've replaced many ID sensors.

Re: Color problem ricoh mp c2050

Had same problem on many of these machines

1. clean the ID sensor board
2. clean the transfer belt rotation sensor on the belt (the encoder disc gets dirty sometimes)
3. Check laser Unit
4. perform calibration

Make sure the paper is dry
Clean scanner and laser optics (mirrors and ld shields)
Clean the ID sensors
Run a forced toner supply on cmy until you get a good solid fill
Run ACC
Then, if necessary, perform the line position adjustments
PDCU replacement may end up being required, although a good charge roller cleaning can do wonders sometimes.
Rock on.

i havent serviced one in a while.."PLASTICA MATICS"
did have to change the sensor brd but i think it was giving me a sc code Way back then

Check PM for PCDU, replace if needed, clean ID sensors.

new transfer group.in sp a b c failed

For starters if "C" fails - which is a rough adjustment, there is no point to do "B" and "A" which are finer adjustments.

+1 on all the comments regarding cleaning the whole optics setup (including the id sensors) and not forgetting the metal plate that sits on the ITB just above the id sensors as well.

Also inspect the itb belt condition. Look for visible dull bands in the id sensor path area, as that can also affect the ability of the id sensors to read the toner.

In sp mode you can also check the result of the id sensors, which if all was well would be "111". If you got a result other than that, it is possible to determine why the test failed. in the service manual values like for instance "2" or "5" will be described to tell you what to check, to resolve the problem.

Also, when last were the drums/dev units replaced - have they reached PM yield?
