Ricoh DF2000 crunching originals

[Will]

Have a Ricoh DF2000 doc feeder that keeps damaging and jamming originals at the lead edge of the center of the sheet anywhere from 1/2 inch to 2 inches wide. It appears for some reason when the original is being feed down and around and across the floating white pressure guide plate (the book calls it a guide: exposure glass part #B386 3513) up into the exit guide assembly where it catches on the lip of the entrance
of that exit guide cover. For some reason the original is not being kept completely flat and sticks up in the middle, at the lead edge of the sheet about 1/8 to 1/2 inch causing it catch. When it catches it either nicks the lead edge or bends it over a 1/4" or bends it over and tears it. Sometimes if it catches enough of the lead edge it stops it and the sheet is prevented from feeding thru. It happens more consistently with the 11x17 originals then the 8.5x11 ones, but still does occasionally even with 8.5x11 especially when running the 11" side. Have tried adjusting the white pressure guide plate with more tension less tension and seems to make it a little better or worse, but can't seem to be able to totally eliminate the problem. Have even tried replacing
the guide and even the mylar strip that lays across the guide with no success. Any suggestions please.

Not familiar w/ the DF code 2000 but your originals may be plowing into the guide due to warpage on the copier top surround of the scan glass or the scan glass might be installed incorrectly. Some models have a beveled edge that must be oriented correctly(denoted by a dot on one side & one end of the glass.

DF2000 is the model number of the doc feeder not a fault code. Would be helpful what part number the the copier top surround is. Not sure what part your talking about.

Copymutt was referring to the slit glass. It is the narrow strip of glass that originals fed throught the ADF slide over

Re: Ricoh DF2000 crunching originals

The easiest thing to try is to replace the separation roller. When the roller gets worn out, it will drive backwards a little bit as the lead edge of the document reaches it, causing the little tears, and frequently continues to turn backwards which will cause misfeeds as the documents will travel too slowly through the paper path. It usually squeaks a lot then, too.
I'm not sure if that document feeder has a feed belt or roller, but either one of them is likely to be worn out as well. Might not hurt to bring one of them along.

What model machine is this df on?

Re: Ricoh DF2000 crunching originals

Check that the right side of the df is in line with the right side of the scanner. The hinges on these are very soft, and people like to push on the df when moving machines around. If the df is not sitting square on the copy glass, the white metal guide, does not sit in the slit glass area like it should, and the paper collides with the slit glass cover - like you describe.

Give that a try.

This is on an MP1600 machine with a DF2000 document feeder.

Already replaced the pickup roller feed belt, and separation roller which made no difference at all.

Already replaced the copier suround as you stated which didn't help, but will double check the slit glass for a bevel.

Re: Ricoh DF2000 crunching originals

If the buckle your describing that catches in the exit guide after the white bar is in the center of the original L.E. then look for warped guides in the infeed turn to the scan glass & wear on the controlling rollers that forward it to this point. Can you cheat the DF set sensor, feed an original & observe from below, might provide more info. i.e. rule out white bar & scan glass parts if you see the buckle. I've seen many guides that have ribs worn down or knicked from paper passage. Minor cases can be sanded smooth.

Re: Ricoh DF2000 crunching originals

This particular model will jam if the slit glass is not in its proper position.....jam jam jam......If someone cleans the optics and doesn't get the slit glass back into its proper position (able to move a little bit in the front to back direction)...it will slam the paper all sorts of ugly....also on older models I have had to add some cork pads to the section that opens up just after the paper is scanned. It gives it a little bit bigger gap to enter back in after is goes over the slit glass. Also make sure the scanner hasn't made copies of someones bottom side hence bending it out of whack.
