Re: Biz hub c425
I did a quick Google search, and according to Google there is no model bizhub C425. Could it be a bizhub C452?
That type of issue can occur if:
*the black laser slit glass is dirty
*the black laser optics are dirty
*poor black developing
*contaminated black primary charge
I could be more specific if I had a valid model number to work with. =^..^=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: Biz hub c425
Even though you mainly deal with Canon the least you could do it provide an accurate model #. Sorry I refuse to even try and help without some very basic information. Model #, Page count, Direction of paper, What you have done so far.....Not going to waste time anymore "interviewing" people who come here asking for help! It's bad enough I have to pull information from my customers all day not going to do it here.Comment

Re: Biz hub c452
A typo? The wrong model # is more than a typo. How about page count, direction of paper, what you have done so far, etc, etc?
Get off that low horse and provide correct information! It will help to get FREE accurate tech support on this forum instead of the same old guessing game!
Best of luck....Comment

Re: Biz hub c425
It's been a minute since I worked on a C452 so I may be getting it mixed up with the C451's but I do recall that sometimes the black developer can start to fail. This is usually indicated by a pooling of developer at the rear of the developing unit. I believe at one time there was a kit of seals you could order to fix the issue, but at this point I doubt they're available. I'd pull out the developer and see if that's what you're dealing with here. The images look like excess developer is spilling onto the print head. Not sure if that's the answer but hopefully it points you in the right direction.Comment

Re: Biz hub c425
The was a big problem with the C451 (C550 and C650 also) that you are thinking of. Not that it never happened on the C452 model line, as I have had some there as well, but it was a lot less likely to happen. Still, definitely a good idea to check anyway with the age of the machine.A Ricoh Service Tech for 7 year. A Konica Minolta Service Tech for 7 years. Now, KM service manager for 4 years.
My Ricoh knowledge is slowly dwindling away at this point. Many things have been lost to time...Comment
