Canon ir 3235 jams paper and keep on showing printing on scree

[copier tech]

Yes that all jas been done by me but still problem persist.
Having a headache with this machine.tried everything but unable to pinpoint problem.

The HDD/System software can cause weird issues like this.

Check in service mode has the machine logged any errors.
From what you describe this is not a jamming issue.
Format the HDD & reload the firmware (fit a new HDD is you have one to rule this out)

Facing issue in ir 3235.it jams paper near registration sensor after 2 or 3 copies and keep showing printing on screen and running continuously

There is a solenoid under the three clutches (CL1, CL2, CL3) below the lower left of the main drive motor, when you open the back.
Over time, it turns sticky. This is because of the foam placed in between the magnetic surface, and the flat lever accommodating the spring. When it melts, it becomes sticky, forcing the solenoid to intermittently lock the gear it is controlling.
I have worked numerously on situations like that.

I have attached a picture with an arrow indicating the position of the said foam on the solenoid. If your situation is the same as what I had worked on, then changing the solenoid will relieve any headache.
When I can't get a new one in time, my alternate option has been to scrape the worn out foam off and clean the surface with a strong solvent. I then stick a sellotape over the surface to replace the foam. If the solenoid is working, this option is even much more durable!

Number 1...what is the jam code?? There is a rubber damper for the registration sensor actuator flag that gets a groove in it(sometimes it just gets sticky). Scrape it off. Also, remove the dampers on the right door(2 on ends of lower diverter, 3 behind duplex diverter.) Post the jam code...

That solenoid is on the back side of each PFU on that model but you are correct. I have had several odd jamming problems because of these pads. I scrape off and put electrical tape in its place and it works fine.
