hello everyone so I have this c203 im working on. I have replaced the image unit transfer belt for other reasons and im getting a weird problem internally when you print gradation adjustments it prints perfect no marks but when I print or copy the lead edge is almost as if it is being erased more noticeable on black and white the colors come out better but u can see a where it wants to black though is noticeable. I thought 2nd transfer roller but then why is halftones ect perfect.it cant be the ccd cause it has bad prints as well so I guess the question im asking is what does print an copy use that the internal prints don't. my other thought is do colors have a higher voltage transfer then black. If it does it would tell me it is possible that the 2nd transfer roller is the problem any suggestions or anything would help

Re: c203 wierd
Do you mean that the lead edge of the image seems to be shifted toward the trailing edge more than it should be?
Is it possible to upload some examples? -
Re: c203 wierd
ill upload images tomorrow at work if you were to look at them you would swear the black image unit was bad the image is there but there is a lot of white on I believe it is the lead edge as if the image did not transfer good but gradation and halftones ect are all perfect it only happens when you print or copyComment

Re: c203 wierd
i will try this on monday im gutting a c253 right now im pulling the boards ou of it to take with me i have some firmware tech support wants me to do (dont think it will work) but i was going to take the roller with me and change it first to see if problem goes away. i cant believe it would be it because the problem changes with orientation and the internal prints dont have any flaws but its a machine lol they do what they want when they want but yes 2nd transfer roller is getting replacedComment

Re: c203 wierd
You have the paper weight set properly?Color is not 4 times harder... it's 65,000 times harder.
They call it "TECH MODE" for a reason. I have manual's and firmware for ya, course... you are going to have to earn it.Comment

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: c203 wierd
Hi, where the back of the transfer roller sits into the frame when the door is closed, there is a metal plate, this gets pitted and causes a voltage drop at the roller, remove the contamination, this should solve your fault.Comment
