Xerox 7760 DN paper jam in the fuser

[karnos666]

Hey Guys,

I'm out of ideas so maybe someone can help me with this.

Randomly we are getting paper jams in the fuser. We already replaced fuser and transfer assembly and that didnt help. We have a contract with Xerox but because we were using remanufactured toner they said that was the toner (apparently different temperature of fusing) and now we need to replace the developer housing, developer and toner dispenser because the whole printer is "contaminated".

What is also interesting is that on a heavier paper we dont have these jams (28lbs) but just on the normal ones 20lbs.

I also already replaced all of the imaging units, toners to original ones and tried to clean the printer a little bit.

Lastly Xerox said that replacing all of these parts would cost 2k, this printer is already 8 years old and has about 120k printouts so maybe if I really need to replace these parts, it's not worth it and I just buy another refurbished unit (anyone knows from where?)

Hi, Yeah well, they B/sing to you. Change the Developers - OK, not a housings, mention to them that changing developer procedure require removing old developer material , ask them to read their own service manual... toner dispensers just need to be vacuumed not replaced. I can do the job for you by the way, where are you located?
The main reason why cardstock goes trough and paper does not is because it has a stronger body and less prone to stick and wrap around the heat roller as thin media would. Technically, if melting point is a problem, make a file with 4 CMYK boxes taking entire sheet and run several hundred of those using a cardstock (put a old fuser back) with OEM toners installed, while print, machine will use majority of generic toner in the system replacing it with original...

UnlimitedBT,

Thanks for the reply.

How much would that procedure cost? Also we are located in Chicago IL so i think it will be a little bit hard for you to travel here (I see you are from NY), but you tell me.

So you think that I should first start with the old fuser and cardstock, print around 200-300 pages with CYMK and see if that will resolve the problem. If not we need to replace developer.

Now so I understand it correctly, to replace developer we take developer housing, clean it up and refill it with a new developer or there is something more into it?

Also can you supply me with the parts# that needs to be ordered/replaced? I tried to find some of the parts on sites like precisionroller, or uninetimaging, or ebay but I wasn't able to find anything that i would think it would work (maybe you have other suppliers that you could recommend).

Also here is my email address: pkornas@gmail.com please contact me directly if you have any additional things that you would like to talk about.

Hi, Noooo I will not travel to Chicago for a service call, sorry . Yes you had understand me correctly, to change a developer, a tech would need to take a DV unit out, clean it, put a fresh developer in it. That is precisely why I said that Xerox is scamming you, there is no need to change the unit unless it is worn-out which has nothing to do with removing generic toner out of the system. It is kind of intensive to get DV units out, I hope you're familiar with procedure... Also, i think there should be a DV initialize/calibration done in "service mode" after replacing developer material. If you haven't done it before - don't go for it. Run plan A (print few hundred sheets) if will not help - seek for a professional help. PrecionRoller would be my #1 choice, you can call them and explain what you need - they should be able to help you with part number and part itself.

As far as exactly what you should need: set of CMYK developers, Special vacuum cleaner for toner (3M makes it) and experience, this is not a machine to start learning basics of Copier/Printer service field. Say, for example, DV unit has a TDC concentration sensor - if you directly vacuum it - it will most likely go bad, than even if you can figure out and manage to disassemble and assemble this machine back, there will more issues because you had created them, at that point you're will be $400-500 down in developers you had just poored in.... You get the picture..
