SC 367 MP-C2500

[ABS tect]

I have a 2500 that keeps giving me a 367 code. The copy quality for the yellow is all over the place, but mostly very light. I have already switched the PCU because that is what the manual prompts, however the copy quality is still very poor. Sometimes it is full and other times it is barely even there. After switching the PCU, the code stayed off for a while and then came back. The manual talks about the TD sensor and drawer connector. Can anyone give me some advice on what the drawer connector is? Since this is the second PCU i am hesitant to say it is the PCU, but that is what most things point to.

I'm hesitant to says it's the PCU too.
So you haven't swapped the developer unit - which is where the TD sensor actually is? That sure sounds like the problem to me.

I just brought a yellow pcu unit from a machine in our shop and the copy quality was perfect. I put it in this 2500 and ran an auto color calibration right away and the yellow was almost completely white, none at all????????

The drawer connector is what the PCU plugs into, I know it is a weird name to give it.

These machines have really easy to break connectors, if you push the PCU in the wrong angle or if you mod a drum without filling down the corner, you can push out the connector. It is not an easy connector to get to.

Have you checked Vt?

I think you hit the nail on the head! And to make it even worse you can't order that connector.

I agree with this too. Now that it's confirmed that a completely different dev/ pcu assembly behaves the same way.

The drawer connector looks to be in place. The first acc the yellow was basically white, after a few forced toner supplies, it got a little better, after repeating this process of forced toner supplies the yellow eventually got up to perfect copy quality, however it will not stay at that place. Wouldn't it not work in general or get better if what you have been saying was the case?

Probably not. If the quality was only fine after you forced it a few times, that most likely means the TD sensor isn't doing it's job adjusting toner levels automatically during normal machine operation, and reason for that is usually a bad connection.
The connector may look like it is in place, but have you tried physically moving it around? Sometimes the wires on the back of the connector can create the illusion of the connector being in place after all.

Did you change just the PCU, drum unit, or the entire PCDU, drum and development unit? If you only replaced the drum unit, you might have left the connector at the front between the two units loose.

Re: SC 367 MP-C2500

I changed the whole thing, developer section as well as the drum.

Try to remove a laser unit and remove metal plate that's on top of it (just the plate,nothing else)

Tell us whether that worked or not when you can, please.
