Feeder misalignment When paper is being fed through the feeder, only the bottom 2/3 of the page is copied. Does anyone know how to adjust or reset the timer for copies through the feeder?

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.

first thsing to check is the side guides for the paper make sure they are set against the paper being fed through if not the paper will be pulled through at an angle and this can cause your problem you can alson get a slightly heavier paper and put that through to see if you have a jam..did you remove all the packing tags and paper protectors

Try cleaning the rollers inside the scanner including the glass inside and out with a soft damped cloth. Look also for a piece of paper, staple wires, paper clips or pencil lead jammed inside the rollers or somewhere in the corner.
Also, look for a foreign object or substance on the cold cathode tube light and clean it. Try also cleaning the mirror.

Go into the paper menu and set the multipurpose feeder paper size to letter. It will work if the paper size is set correctly for the MPF.

to fix misalign and paper jam problem, follow this steps.

Load one or two sheets of unused plain white full-size paper into the document feeder tray, and then press Start Copy Black to pull the pages through the automatic document feeder. The plain paper releases and absorbs residue from the rollers and separator pad.
NOTE: If the automatic document feeder does not pick up the plain paper, try cleaning the front roller. Wipe the roller with a soft lint-free cloth dampened with distilled water.

If the problem persists, or the automatic document feeder does not pick up the plain paper, clean the rollers and separator pad manually.

Follow the steps below to clean the rollers or separator pad.

1.Lift the cover of the automatic document feeder. This allows access to the rollers and the separator pad.
2.Lightly dampen a clean, lint-free cloth with distilled water, then squeeze any excess liquid from the cloth.
3.Use the damp cloth to wipe any residue off of the rollers or the separator pad.
4.Close the cover of the automatic document feeder.
This should solve the problem. Cheers!

Yep. remove and clean that small strip of glass on the left side of the machine. open the feeder, there are 2 phillips screws, that glass either has somthing on the top or bottom surface.
It makes it easire to clean when you remove it and place it on a white sheet of paper, that way even if it is a really small spot you can see it easier.
The lamp does not move when you use the doc feeder and a small spot on that glass will make line across the entire page.

Its most likely to be the pickup roller and separation pad which will need replacing. as a short term fix try cleaning them with some isopropyl alcohol

does the same occur when the manual paper feed path is used? has this problem has just "popped up" without notice or was it a gradual event?

Does it happen both off the copy glass & thru the document feeder or only off the document feeder. If both - check the side guides inside the cassette to make sure they are tight against the paper. If it only happens when using the feeder- the feeder tray needs to be adjusted. There is usually 2 screws under the document tray that when loosened allow for side to side adjustment. Moving the tray should solve the problem if it is only happening when you use the document feeder.

Are you sure you don't have a static problem locking the paper to the glass.
