Print / Copy quality is very poor on RICOH MP-2554SP. (Corona Series)

[nadimtopsecret]

Dear All,
I'm facing a problem on Ricoh Aficio MP-2554SP (Corona). Copy or print quality is very poor, First I've replaced OPC drum, then developer. But problem not solved then I also replaced full PCDU unit and Laser unit also but after a few days problem appears again. Another thing is that, if I give force toner supply by entering SP mode, machine runs well 2-3 hours but again copy/print quality became poor .
In this regard please help me to solve this issue.

What's the meter? Could have a bad toner motor.

I don't have exactly this machine but i have mp3053 and i have the same problem on a mp9002
in my case was the td sensor and the id sensor and i changed on the 9002 the Electric Potential Sensor

On the 2554 open the side door and somewhere in the center you will find the id sensor try to clean it.
Check the values from the sticker with the qr code and reinput the value in sp mode SP3-331-061
play with the td sensor and id sensor settings to see the faulty one
for td check 3-031-001 if is 1: Success any other is faulty
for id 3-074-001 execute the id sensor check

+1 for this.
I've had to change the ID sensor for this model a few times now.

I didn't read anything in the original post about a Developer calibration being done either with the fresh Dev OR the entire unit

There's no calibration to be run on these.
From the manual:

"If you replace the PCDU, you do not need to perform SP 3-701. This is because the machinedetects a new unit automatically when you cycle the main power off/on, and performs the initial
adjustment automatically."

Even though it tells you to run SP 3-701 if you replace an individual pdc or dev.

This because you can put inside a used one just for test from other machine so it is not new just for the machine
