MY Canon PC 795 copier shuts down after five minutes , also has on going paper jams.
The blinking light with the squiggle symbol is the display for a paper jam. Not sure a service manual will help in this situation other than to be a guide as to where the paper sensors are located. There are usually 3 or 4 paper sensors located in Canon PC copiers. The first sensor will be located between the paper pick up assy and the vertical rollers*(*which are located behind the door on the right hand side used for clearing jams). The second sensor is located under the toner cartridge just before the registration rollers. The third sensor (if present)is located at the entrance of the fuser assy (some models of Canon copiers have omitted this sensor)The last sensor is located at the exit of the fuser assy. I would suggest that you remove the cassette, verify that a piece of paper has not been partially fed or ripped in the pick up assy. With cassette out of machine, open right hand door & verify that there is no jam and check that the flag or arm of the sensor moves freely. Remove the cartridge from machine and again verify there is no jam and the registration sensor arm moves freely. If there is a sensor in front of the fuser assy, verify that it also moves freely. Finally, check for a jam and sensor movement at the exit/fuser. After checking all sensors, unplug the machine and plug back in. (Do this without the cassette & cartridge installed but with all the covers closed) This should give you an install cartridge & cassette message. Install cartridge first. This should give you the install cassette message. Install cassette. If you still get a jam signal when plugging the machine in without the cartridge or cassette, the most likely cause is a blown sensor.(rare, but I have seen it.)If this happens you would then need the service manual to disassemble & repair. I'll keep an eye out for your reply! Good Luck!!!
I checked out jam section "c" found no trace of paper--sensors feel loose and free---I hvaen't feed paper into this printerfor a couple of months---I had to replace a magnatic clutch--before that it never show about a paper jam--this started to show up after I changed the clutch--can't get it to run-until I find out
can't run the printer until I fix the jam problem

Your solution was very helpful. I look at sensor #2 and found the problem. It was not paper that cause the error, however a roach decide to start up her roach hotel at that location. Seems your good in what you do. Here is another problem on another printer.
The printer is a HP DC 610. The problem is I have an error message that keeps re-occuring. Scanner failure. I have clean the scanner assembly and mirrors to see if this helps to clear the problem, however after 5 mintues or so. The error returns. I don't have enough money to take to a service tech, but I enjoy working on printers. My mechincal skills out skill my knowledge on this different types of printers, however I still enjoy working on them. Please e-mail @ [email protected] with your solution.
Thank you once again for a great solution,
