Where dev units changed?Originally Posted by Pixtech Frameworks
if you happen to forced toner to supply and still no effect... i would suggest to check your toner sub hopper perhaps coil are broken and can't supply.
good luck Sir.
fix the customer first then fix the machine... its simple and makes life more easy.
You NEED to change the dev units. That's what puts toner onto the drums.
Turdparty toner DESTROYS dev units.
You can change PCU'S all day long and you are just wasting money UNTIL dev units are replaced.

Exactly.
All that money they “saved” using cheap toner is now going to be buying new dev units.
turdparty toner only benefits one person.... the jackass that sold the toner.
Saturation of the colors are faint probably due to a wrong ID reading output, because ACC fails.
You must first solve the ACC problem before repl. developers, drums...
ACC is a ITB matter.
Did you replace the ITB cleaning unit?
Did you checked the ITB belt?
What is the image on the belt like? This will help determine which process is causing the problem
You appear to have no yellow on the page at all, could be PCDU, laser or transfer related, is the bias transfer roller for Y in correctly? Have you cleaned the laser slit glasses?
The colour registration is also out, have you cleaned the ID sensors? What is the life of the belt?
There are 10 types of people in this world, those who understand binary maths and those who don't
Just had a quick scan through the messages and don't think anyone mentioned this (and I'm fairly sure it happens on this model drums) but the plastic cover on the back of the PCU has that little metal plate inside it. If someone changes the PCU and does not fit that back on after there is no contact and you get very faint colours.
Not that I think it is this but pull out the ITB and check that all the red wires on the back of it are in good condition and silver metal connections are still there as normal. Only ever seen damage back there once but just something I have always remembered.
Obviously dev units have been mentioned, once you use fake toner that's it, doesn't matter if you put genuine toner in afterwards, those dev units are now infected and always wills be until they are replaced.
If you follow every piece of advice mentioned and update firmware clean everything replace parts etc The last thing to do...and most people here would hang me for saying this but memory clear could save you IF you know what you are doing.
The only reason I say that is because I have had MPC 2503 (same machine really) that had misaligned colours and I did everything under the sun to correct it but nothing worked, someone suggested clearing 1 part of the memory as long as I had the birth certificate, which I did. So I had nothing to lose as this machine was in my office, after typing all the data back in for about 30 minutes it worked perfectly. That 30 minutes of doing something which is an absolute last resort beat the hours I spent doing all the more obvious things. Only a trained engineer should ever attempt that though.
hi, check the following conditions:
1) you, or someone else before you, may have forgotten to mount the back cover to some pcu
2) check the plastic parts fixing the rollers behind the ITB, they could be broken or out of place, preventing the correct contact between roller-belt-pcu.
3) clean the id sensors and laser glasses
