I have an A16-525 error (even though there is no master on the drum)on RISO RP3700?

The machine was working fine until the master disposal had a jam. How can I reset the machine so that a new master can be made?

Press life "2" start for toner.

And life "3" start for drum.

These will reset the counters.

If you are having a "check drum error" then you have broken the sensor arm that is attached to your lid.

Call a technician in your area.

Remove the master that is on the drum. Then check the master roll remove it cut about 18 inches off then re install master roll. hit the reset, then print bottons.

I had this problem too: just unlock the hook under the drum; disengage the drum then pull out the drum; then check the home position if not in position open the behind cover, pull the belt until you get the puller to the home position. You will get the same problem if you will not put the main drum puller to the home position. chimuntu@yahoo.com

SOURCE: drum stuck RISO RN2235ui

Hi,
assuming you have a RN machine
you should of removed the master on the drum by hand if it was not used for more than a couple of weeks, and wipe dry under the clamp.
To get the drum out, hinge up the top of the machine over the top of the drum there is another small door, it hinges up like the top of the machine.
At this point ensure that the drum is in the home position i.e the clamp of the drum is at 12:00 (on top). if not turn drum to that point by hand.
Then try the button again to release the drum. If that fails there is a small **** under the drum at the front door area. there is a catch there that holds in the drum which you can move to the side with a flat screw driver.

Riso rp3700 drum is stuck


Assuming that it is still in the locked position. Open the top and observe the position of the drum. Rotate the drum the normally locked position. i.e. The master clamp on the drum is in about the 2 O'clock position. Put in test mode, enter 556 and push start. That may release the drum.

I have a Riso RP3700 that we have been running NCR paper on. But the pass few months I have been getting jams after a few runs of the NCR it is always the pink copy that get jam on the drum. Can someone...


All you have to do is to ensure the image is pushed down the page. Either on your graphics software or on the RP3700 itself and by using the image offset function. Try 2mm at first.
If the image is too close to the margin the paper has trouble releasing from the drum as the ink makes it stick to drum. The little hook cant then get under the paper hence jam.
I am confident this will work.

Maybe you meant model RP3700 ...

These questions may help to find a solution or at least a better understanding of your problem:
Have you set the paper size right?
Is the print drum capable of the desired imaging size?
