LC 810 Jam Code 000C

[costd]

I have tried looking on the Canon site and cannot get the info on this code (I know - get a manual). Tech Spt (without defining the issue) is telling us to replace the reader controller board.

Sensors have been checked, motors also. It appears the delivery roller on the ADF is not turning. Until the manual gets here, no wiring diagrams etc - so....

The only thing I can add to this is that this is a power on jam 000C. There is a case on this jam code except its a delay jam 010C which refers to the the delivery sensor (SR5)
SR5 is a photo interrupter connected to connector J107 on the DC Controller PCB. Not to sure if this helps, but its the closest thing to that jam code your getting.

You are right code is for ADF
Delivery delay jam 000C

remove side cover>Check Roller release solenoid

the internal software signal "Delivery Sensor OFF" set in the system cannot
be detected, when the leading edge of paper is detected by the document edge sensor
and fed the prescribed distance, and after the paper's trailing edge is detected.

Check the paper path for obstructions.
SR5 is a photo interrupter connected to connector J107 on the DC Controller PCB.
--Check that the actuator is present and correctly installed
--Check that SR5 is still connected to, and powered by a 3.3 VR voltage from the DC Controller.

Thank you Screwtape and Teckat. I did check the sensor (actually swapped it with a know good one) but did not know where "the other end" went. Checking J107 for 3.3 v will be my next step AND I will delay ordering the reader controller until I can check things a bit more. I will also take a look at the solenoid as I already have the whole back end open.

Thanks again and I will post back results within the next day or so.

Latest update: Since I do not have a manual yet, all I have to go on is the actual device itself. The sensor, motor, and solenoid do not connect to the DC Controller - they connect to the reader controller. The sensor gets 3.3v and the motor is good - paper does not make it to the last delivery rollers (solenoid) as the rollers just before do not turn (because motor does not come on.

New to this, but here is my thought: the sensor (good) tells the motor (good) to start but it doesn't. Only item connecting the two is the reader board sooooo...... Maybe?

Good news is since Canon said replace the board I can return it if it does not fix the problem. Now I need to get on the boss to order the service manual.

Thanks again

The Image Processor PCB=detects the state of each sensor of the reader unit and the ADF./ voltage supply & a change of state are two different checks on SR5



When the original reaches the registration roller where is it looped, the pickup solenoid turns off and the pickup unit roller rises. Next the registration
solenoid turns on and the original is fed by the registration roller. At this time, the pickup roller drive shaft which is rotated via the spring one-way clutch
is stationary at the highest position in the pickup unit. The pickup roller incorporating a one-way clutch is rotated by the friction against the paper.

The original that passed through the original feed/delivery position is fed by the delivery roller which is turned by the ADF motor. The delivery roller
is normally held pressurized. It is released when the roller release solenoid turns on

The sensor, motor, and solenoid do not connect to the DC Controller - they connect to the reader controller.

Interesting..

why would the sensor come off the Reader pcb ???

That's what I'm saying..
Another one of those, humm.

Beats the shit out of me but replacing the reader pcb fixed it. As I said, that was the board where the connectors for the sensor and the motors "met" so..... Thanks for all the help - now on to the next one.

also just found this out / this model does use the READER PCB for the sensor SR5

in the iR 1018/1022 a similar machine , it uses the DC PCB for SR5

good fix/

Very good. Thanks for posting back with the solution.
