Re: jam on MP6001 feeder

You have a foreign object jambed in the ADF feed path, Or the mylar guides have been reverse from someone being forceful.

With the ADF top cover open:
Use a piece of A4 heavy card stock and push it through the ADF paper path downward from the top.
Use care not to damage the mylar guides if they have been fold backwards and reversed.
The A4 card will remove the paper clip or staple jambed in the ADF feed path an may turn the mylar over if its not too damaged.


FYI: Plastic A4 binder covers work best for removing foreign objects from the ADF.

Re: jam on MP6001 feeder

I have seen a lot of this type of jamming lately. It happens more on scanning because of the speed of the adf is different than on copying (200 vs 600 dpi) It also will give you a noise issue when it happens. Remove the rear cover of the adf and look for the exit drive motor. Its the first one on the right if your looking from the front of the machine. It has one drive belt that goes to another drive gear (white) that drives another belt for the exit drive unit. I squirt alcohol while running the feeder in copy mode and then in the scanner mode on all of the bearings related to that drive. Works all the time. Dont forget to also do the front bearings and the one near the CIS.
A little WD on the bushing\bearings would also not hurt,just make sure that you dont use it on the one way bearings on the paper feed-in drive on the left looking from the front of the machine.
The first attachment shows the exit drive motor, the second shows the bearing by the CISIMG_0944.JPGIMG_0946.JPG

Re: jam on MP6001 feeder

I want to add a few more observations after looking at your attachments. In sp 8191 I can bet that the count is over 800k. The guide plate on the upper unit is worn down to almost nothing. I would also replace the lower guide plate. They get a dip in them right after the sep roller that causes the paper to buckle as it goes in. Also remove and clean the one way bearings and shafts on the right side. Some times they are so shot that they need to be replaced. Do not use any lube on the bearings or shafts. If a good cleaning works, be ready to replace the bearings and drive rollers as a set. You will see the wear marks where the one way bearing and shaft meets.

Re: jam on MP6001 feeder

From looking at the images, the lead edge is jamming near the pre-scanning roller. Either the roller is not turning, there is something the the lead edge of the paper is hitting (staple, paper clip or paper scrap) or the idler rollers are not against the pre-scanning roller.

My guess is for the regroller shaft and it's two oneway clutches.

May i ask what the solution was, please?

Re: jam on MP6001 feeder

i am still suffering This problem happened mostly on the 1 side copying and it damage the original when we try to run 2 side the problem became more less

Is there is way to reduce the speed of the document feeder while copying

Re: jam on MP6001 feeder

I ran into the same issue and concur with Brian - replace the upper and lower guide plates.

Re: jam on MP6001 feeder

This looks like the same DF jamming problem that I and quite a few Copytechnet techs have been chasing for a white now. There is a thread for this somewhere.
Try scanning originals at different resolutions as the DF will then run at different speeds, if it doesn't jam at hi resolution/ slow speed its the same problem that has been baffling us for a while. If this is the case try reducing the tension on the drive belt on the motor that drives the exit side of things. If that reduces the jams you need to fit a new motor.
My theory is that the motor is getting tired and not getting up to speed quickly enough, reducing the tension on the belt reduced the initial load so gives the motor a millisecond more to get up to speed.

So far Ricoh NTS have been very slow to recognise there is a problem let alone come up with a solution.

There have been similar ADF issue spoken about before you may like to try the following post and threads.
