I get a gray band on the printed page. I have cleaned the rollers and the machine several times. The band did get smaller and a bit darker after cleaning. Is this a common problem? Could it be the toner cartridge. Thanks Larry

the two places to look is transfer roller and the fuser unnit.
i think there is a problem with the transfer roller it is under the toner and it needs to be spring loaded. The paper passes between the toner an the transfer roller to charge the paper en let the toner stick to the paper and if it doesn't make correct contact then it wont work
Yes - surprisingly - we had the same problem, the gray stripe along the side of the page only showed up when the original was fed through the document feeder on top. Cleaned the small area of glass under the feeder repeatedly with no change to the resulting stripe, but then while cleaning the upper roller, above the area of glass where the scan lamp illuminates during the copying from the ADF, we found a small piece of paper adhering to the top roller in the paper path, cleaned it off, and no more band. We didn't see the bit of paper on the upper roller until we rolled it while cleaning. Still can't figure how that made a stripe....but hope this helps you.
hello does the grey line appear if you scan true the "upper" scanner.(set paper on top of printer and sscan it that way)? you should also clean the smal slim glass that is at the side of the big scanner glass. also try to remove all cartridges and tilt them side to side several times. then put them back and test your printer.
your problem could be one of many things first try stoping the copy half way in the machine. to do this open the front door and cheat the door switch with some folded up paper or use a flat screw driver to bypass the switch. make a copy and watch the paper when in goes into the drum and starts to come out like 3 inches pull the screw driver or paper out of the switch. carefully pull the paper out from the machine and see if the image is ok. if the marks are there the problem is with the drum. if the image is clear and there is no marks then open the left door on the copier and inspect the rollers in the heat unit. to do this open the left door the front door has to be open to do this. there is a little green lever on the right side pull this down and look at the 2 roller if you see marks on the top roller or dirt on the lower roller this is your problem. also check the miliage reading on the drum if there is a sticker and check the meter on the machine the drum is rated for 55,000 copies.
There are several things that can cause this. A worn toner cartridge and/or transfer roller can cause vertical smears, but it may also be a worn fuser assembly. The teflon coating on the fixing (heat) roller wears off, and leaves vertical streaks of varying widths on the pages. Sometimes you may see "ghost" images on the pages for the same reason. Open the back door of the printer, and hold down the exit guide on the fuser (carefull, it may be very hot). There are two long rollers, the lower one is black, the upper roller is either grey or shiny brown. That's the teflon coating. See if it's peeled or damaged. If so, replace the fuser assembly.
