Re: canon ir3100cn E000020-0081

Hello Eeel,

I heve been a field engineer working on Canon copiers for over 20 years. But there was a gap in my exposure to Canon equipment while I helped roll out our company's newly aquired RICOH product line. The ir3100 fell in this gap area. I went to the Canon technical support site and despite the fact I am not trained on that device, apparently my previous training and new training since that machine provides me with the credentials to view the technical information for this machine. Canon is extremely anal when it comes to allowing their tecnical information to be viewed. I was trained on their newest 105 copy a minute machine and denied access to human support or documentation on a 16 copy a minute machine recently. Anyway,I am no expert on the 3100 but I can explain and describe the meaning of the error codes The E225 meant that the scanner (the system that illuminates and moves (scans) across the document ) was moving at uneven or varying speeds. This could have been caused by shards of the broken glass interfering with the smooth and constant operation of this assembly. The manual says to loosen the scan motor and re-tension it as the assumed normal wear problem is that the belt that provides drive between the motor and the scanning assembly may have stretched. It fact they suggest replacing the belt (XF24606740). But I would assume it was a function of the the platen glass being broken and debris causing uneven speed. Next the E20-81. Since you probably don't get toner in your ears as often as I do this may be a challenge. There is a sensor that emits light to generate a reflection from the drum in order to measure the drums sensitivity and test patches of color as the machine calibrates itself to determine the optimum copy quality. It looks at the drum when its completely image free (blank area of document to minimize background) and each color to determine what adjustments need to be made for optimum density and clarity. If the light emitting diode has a haze of dust(toner) over it then the values it reads will be skewed and in your case out of range for adjustment(E20-81) This typically happens if machine has not been vacuumed/cleaned in a long time or if it is moved which tends to dislodge any garbage that had been innocently lying around until it was josteled loose. I dont have a manual for this machine that will tell me precisely when this sensor is located and the procedure to optimally access it. I can only say that a good vacuuming of the core of the machine would be the firtst step. To what degree you can access this sensor (which is called PS23 .part # FH77629000) without disassembly of some or the core of the machine I cannot tell you intelligently. I am sorry I could not be of more help. I hope I helped a little .Good luck Hello Eeel,
