[Jamming] Canon IR2020 jam registration clutch

[Zoollanderhu]

Hi Guys!
I've got a really funny problem...even it isn't funny So I've got an IR2020 that makes jam at the registration roller , namely the registration clutch doesn't give any drive for the roller.

I've test it at open door.When test it at open door the first two pages come out ( of course the reg. roller doesn't spin) but it goes trough the machine so no jam occurs elsewhere).
You would say change the clutch, I've done it and nothing has happened and the most interesting is when the machine test itself the clutch works. When it test itself it works properly but when it prints it doesn't work or spin.

Think that it's some kind of DC panel problem or not getting enough Voltage but why does it work at the test and why doesn't at when it should work?

It has been already updated with the lates firmware from the Canon tech site and ALL Clear but without any effect .


Anyone who has met with this? Or any idea?

Sorry I can't give you jam code as it always stuck.

Thank you in advance!

Hi Mr Zoollanderhu, I come across a similar problem. when you copy/print one or two it works well and no jam. But when ever you copy/print multiple it always jams. on one of the machines it was the clutch that was faulty and when i replaced the clutch my problem was over. Again i have the same problem with another machine and when i replace the clutch it did not work, but when i change the DC controller it was fine.
since you have change the clutch and it did not work, i would suggest you change the DC controller. Thank you and good luck.

Hi!
Thank you for your help and idea. Yeah I asked a lot of people and they said i should look after the DC as the clutch is good at the test.
Normally the clucth slips and just a change resolve everything but a the DC will be more expensive than a simple clutch.
Anyway thank you for your idea.
Best regards,
Norbert

Check to see if the voltage for the clutch is being generated at the DCon at the proper pin and connector. A 5 minute measurement will tell you if its the DCon or not.Troubleshooting is cheaper than swapping boards. I have seen lazy actuators at the paper cassettes cause this problem on these machines.If sensor is still actuated timing window screws up and clutch dont turn on in time. Extra spring wrap might fix it. It is a cheap start

the problem is the voltage must be as when the machine test itself the clutch gets the voltage and works..... so voltage is good unfortunatelly.... anyway thanks

What i meant is put your meter lead on the pin on the connector on the Dcon that turns the clutch on,hit start to make a copy and see if the voltage is there. Not in service mode..means nothing. You have to see if the Dcon is sending the signal to turn the clutch on in normal operation. Troubleshoot it. If the voltage acts accordingly, Dcon probably ok. RESEAT connectors.

Hi Guys!
I tried the Dc panel at another asset and it worked properly.So the DC can't be the foundation of the problem. more inspection was and we saw that on the surface of the drum there isn't a latent/virtual image .... so no clutch drives when it should and no latent imgae---> no laser unit..... it seems these problems are from Image PCB...... it's also control the DC. Too expensive part change for a 2020 which has a counter with 400.000+ ....new machine will be....

Hi Zoolander!
Sometimes the registration sensor flag wears off, and couldn't detect the paper. In this case the machine usually can copy from the manual tray because of other angle of incidence.

Maybe this can also help you:

In my experience some iR2016-2020 could have a faulty cassette feed clutch (CL202, FK2-1068 ).
It can cause different types of jams, and the machine can complain about not proper paper size.
The clutch became hot, and could slip.
The fastest way to identify this problem to draw out the cassette1, put in your arm, cheat the paper type sensor and the paper sensor, and push the start button. If you can slow down the pick up roller with your hand, you must to change the clutch.
