Xerox DocuColor 252 (DC250) random cyan spots
I've seen a couple of threads on the subject here, but none have solved the problem so far.
A customer has a DocuColor 252. He gets random cyan spots on every other print or so. I have attached an example.
So far I have changed drum, then developer, then toner, and all filters. Changing developer helped for a very short while (200 prints or so), but then the problem came back.
Not sure what else to look for. Developer and/or drum drive maybe?
Did you replace the Developer Housing and Developer Charge (Powder)? If you only changed 1 you will need to replace both to be on the safe side. When the developer was replaced did you input the new numbers into the machine for the ATC sensors? Check Developer housing to make sure that the cover is flush on both sides and has 3 slots inserted into frame. Has to go in on an angle. Both sides have to be snapped in over the rounded edge to make a complete seal. If not make sure you input those numbers in there.
Next check the dust shield inside the machine by pulling out the drum drawer and cover from light, pull out the fuser drawer out and then push in both "stops" on each side and pull further. Small hole in middle of rail. Clean the rear of this drawer, build up on the 2nd BTR connectors. Open the IBT drawer, BE VERY CAREFUL REMOVING THE IBT IF YOU CHOSE TO. (You have to extend fuser drawer as noted above)
Inside the machine on the right hand side between the drum drawer and fuser drawer there is a black plastic cover. There maybe a build up of toner on there. Get down on the floor to get your hands up into the machine to clean with rag or vacuum if needed. If you cant you will have to remove the fuser drawer. I would suggest that if you chose to remove the Drum, Fuser and IBT assy drawers you may as well clean the ROS fans, entire cavity in that area. Better safe than sorry on this one. If that does not work and you are still dropping toner. See below.
Check and run the Toner Dispense motors to make sure they are not clogged up shooting toner when it unclogs. Clean entire drum tray to include the metal support brackets are free of toner. Error codes in the 093 range would be in history if any had issues.
99% of the time replacing the Developer Housing and Charge (Powder) has solved this issue. If you have picked this up on a new contract, spend 1 hour and clean the machine to save yourself alot of time down the road for CQ issues for dust related issues. NO GENERIC TONERS, DRUMS on this machine.
