Canon iR105 finisher tray B keeps on lowering when printing or copying

[mafifulos]

Good Day, I am a noob technician on copier machines, can you please help me troubleshoot my problem a Canon iR105 copier machine, When i print, the finisher tray "B" lowers down automatically, even if i pull it up, it will go back down when i print or make copies. I have tried replacing the motor, sensors, almost everything that is inside the tray B from our other working canon iR105 machines so i can troubleshoot. still no luck, what is the problem. Please help.

If you let the tray go down does it attempt to come back up, or does it throw an error code?

No sir, It stays down, if i pull it up after a few seconds it will slowly go down. but if the machine is in idle and i pull it up, it stays up. there in no error showing.
It only goes down when i'm printing or copying files.

could be a variety of things.. lift belts are wacked.. lift motor not working .. lift sensor not working.. get the manual and go thru the suggested steps.

I hope you don't have "limited function" on display.



Like Phil say use SM and check switches on finisher controller.

Have you tried swapping the entire tray b? Finisher controller? I think I have seen this with a assembly inside the tray, try swapping tray b with another one, see if the problem stays, then the finisher or controller, if problem gone it is the tray.

I already tried swapping all the inside parts from another printer sir, tried the motor,sensor, small board inside the tray, still no luck.

We are not using the other modes sir, only the tray is on, same settings from all the machines, there is also no "limited function" on the display.

I would want to try that also, but as i said, i am a newbie copier technician, I'm only a certified computer technician and has experience only in repairing laptops. I tried removing the tray "b" but i cant find any instruction on the manual and google on how to remove it. can you give me a small hint on how to remove it sir? TIA.
