I had posted an inquiry earlier. At that point, we had replaced the fusing unit and drum, but were getting dirty copies just like before. Now a new wrinkle has developed. If we set it on color, we do not get the dirty copies. If we set it on rotate/sort (in black and white), we get clean copies as well. Both of these settings slow down the machine, so I suspect that speed has soemthing to do with it. Does anyone have a clue what is going on?

One or more of the drum units or the transfer belt cleaning blade is bad. Only way to tell is to remove each drum and check the surface for the toner "streaks". You can also pull out the transfer belt and check the surface for the streaks. It will be one or the other. Now if you streaks are of a particular color then that points more to the drum of that color.
Hi sir; No matter who told you to replace, the hot roller is the most possibility, the next item also last item you need to check is drum unit (drum cleaning blade,[replace it ], image transfer roller [clean up by alcohal] and drum [ depend condition ]).
Do you have the copier feature option installed? It is most likely just a loose connection on the interface between the main printer unit and scanner section. Turn off main power (red button), and re-seat the connector.
Which feeder? Is it in the document feeder or the paper tray?
Could need a pm to replace the drum, cleaning blade, and possibly developer to get rid of the dirty copy and/or the scanner section should be cleaned as well by cleaning the glass as well as the mirrors underneath the glass.
Hi , if you make a copy through the document feeder and there is a line it is on the mirrors , they need to be cleaned , but if you do a printout from your pc or a config psge from the copier , it could be only one of two thing , either your hotroller is getting worn (it normaly wares were the thermoster touches the roller )or tour pcu unit has made its hield and needs to be replaced , you can open the pcu to see if there is any dirt , but i would not recomend this as it is a very dirty job and if you are not experienced you will end up scratching the drum and you;ll end up having to change the pcu in anycase .
This Code relates to color gamma error in the Yellow development. Possible causes Low toner density in the Y toner,Toner supply Y mechanism problem( not supplying enough toner),Laser exposure problem, image transfer problem. My suggestion would be to ensure you have toner in the cartridge( but by this time it has depleted the developer), and you will need to replace the development unit and possibly the drum Unit. My best guess would be the development Unit.
