Need replacement process for paper feed roller in scanner compartment.


On the doc feeder there are 2 arms that go down into the machine. UNPLUG machine first. You squeeze them carefully and rock the doc feeder backward. It may take some manuevering,

Once you have separated the top half of doc feeder, you will see a wire harness going into the upper half, CAREFULLY unplug it. There are several screws holding down the cover over the bottom half, remove them and again carefully separate this cover from the main body.

Once this is done you should be able to replace the feed roller. One note, while you have it this far apart you ought to change the separaetor pad in the top half.


If this helps you, please log in a vote for me, thanx

Toshiba 2860.. auto doc feeder keeps jamming.. seems like one side is feeing and other had side isnt or something similar. Any ideasa?


In any doc feeder, the initial two feed rollers and one paper separator pad/roller handle most of the paper transportation. So usually if you have misfeeds, and the paper is not crumpling up, you have a problem with worn or dirty feed rollers. However, if the paper is getting crumpled up, you most likely have a physical obstruction blocking the paper path. My recommendation for when this happens is to take a thick piece of card stock and manually feed it through the paper path on the doc feeder, this usually acts to unclog any jammed paper bits or debris.

Getting a dark line on the copy pages. Need a new


Mite be a problem with your doc feeder. Are you using a doc feeder? If so raise up the doc feeder and place an orgnial on the big glass instead of feeding the orginal thur the docfeeder. Does the line disappear? If it does then the **** glass the small glass used by the docfeeder has a mark on it or dirt. Is your machine a printer also? Does the print have the mark/line on them also. Do any of your machine's internal reports have line on them Meter Read print outs etc.

Feeds document too far before it starts copying.


The doc feeder is a little finiky, try letting go of the doc as soon as the feeder detects a doc in place and not force it through the feed slot.

Doc Feed Problem


I would replace the Pick-up roller, Feed Belt, Sepearation roller, and torx Limiter for starters IF you cannot replace them, Clean them with warm water and soap, let them dry, and try the doc feeder, Most Multi feed problems are Torx limiter or clutch problems.
