Paper Feed Problems Riso EZ591

[nprint]

Good evening everyone, I am having an issue where the machine pulls the paper in about 5" then stops and says jam.
I was told its the timing but i am not sure what to adjust, i have the service manual. any input would be greatly appreciated

regards

Can we check the counter of the machine?
Have you check the stripper pad? Pick up Rollers?

I have 300K on the machine, new pickup rollers and stripper pad

jam code?

J8 is what i see

no feed at all or intermittent jams? J7 as well?
suggest first to clean the registration sensors, probably covered with paper dust (pickup rollers and stripper pad good?).
replacing the one-way gear at the timing roller assembly follows.

First how many copies on the feed tires and sep pad? How many copies on the machine?
Here is a RISO publication on jamming.
Good luck.

Blow out the paper in sensors. Clean or replace the feed clutch. Replace the one way timing gear
