Canon 7105 finisher

[stek]

Hello!
Have a canon 7105. When copies are exiting the finisher (top gate) the bottom gate will proceed to move up and down constantly. It does not seem to jam though. It will also drop to the floor sometimes. When this happens I have to turn the machine off and on to proceed. No codes!

Thanks!

Do you mean tray?

Yes. Paper is exiting the to the top tray while the bottom tray proceeds to move up and down constantly. Can I post MP4 video's?

Is this the V1/V2

if all checks fail
Complete Operation Assembly is FM2- 6376-000

Tray height sensors ?

Adjust the sensor intensity.?

This Article details changes made in the aforementioned Finisher / Saddle Finisher Tray Paper Surface Detection Sensors. Cause As a result of the discontinuance of one of the electric components used to manufacture the Tray Paper Surface Detection Sensors, the LED PCB Assembly (FG3-0082-040) [1] and the Detect Sensor PCB Assembly (FM2-5709-000) [2] have been changed to a new type. Action If the LED PCB Assembly or Detect Sensor PCB Assembly Sensors should fail in the field, they can be replaced individually. A 'Set Replacement' is not necessary as an 'Old – New' combination will work. Service Parts CAUTION! Use of the incorrect LED PCB Assembly or Detect Sensor PCB Assembly can result in the Paper Trays descent, but then it will not return to Home Position. As the old type LED PCB Assembly and Detect Sensor PCB Assembly are used on other models, their part numbers have been revised so that they can continue to be used on the other models. Description Part Number 1 Old LED PCB ASSEMBLY FG3-0082-040 New FG3-0082-050 2 Old DETECT SENSOR PCB ASSEMBLY FM2-5709-000 New FM2-5709-010 The LED PCB Assembly or Detect Sensor PCB Assembly for the Finsher- AB1/Saddle Finisher-AB2 and the Finsher-V1/Saddle Finisher-V2 are different and have been assigned brand new part numbers. ONLY USE THE SUBSEQUENT BRAND NEW PARTS in the Finsher- AB1/Saddle Finisher-AB2 and the Finsher-V1/Saddle Finisher-V2. Service Parts for the Finsher-AB1/Saddle Finisher-AB2 and the Finsher-V1/Saddle Finisher-V2: Description Part Number Figure Number 1 Old LED PCB ASSEMBLY FG3-0082-040 L20/L30/Q2 New FM1-G879-000 2 Old DETECT SENSOR PCB ASSEMBLY FM2-5709-000 L20/L30/Q2 New FM1-G880-000

Hope this will help

Clean the receivers and transmitters before you initialize the sensors. The paper stack sensors project across the paper tray so when stack reaches a certain height the tray drops a bit. Also, on the trays themselves there is a board with photo interrupts that look at the tray's position along the guide rail. The screw to mount the pcb with the photo interrupts on it comes loose and pcb flops around
