    Canon NP2120 e000 - how do I clear it?

    LIke most copiers I've noticed you can simply clear the error log and get rid of this error. Anybody know how this is done on the 2120? I havent been able to find a reset switch or anything to clear this error out.

    On the left side cover, behind & below the exit tray there is a small rectangular plastic cover ~35mm & ~55mm. Remove this cover and while the power is ON press the momentary push switch on the top edge of the small circuit board inside. The error will be cleared.

    Don't turn the VR's until you know what they do, and how to do proper adjustments. =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      clearing code on 2120

      the best way to clear it is to unplug the power cord, take the machine and throw it in the dumpster.

        Unfortunately the error message may be legitimate as upon attempting to clear it as per your message the delivery roller became extremely hot and had a burning smell. Could this be a jammed piece of paper or something simple or should I take the guys suggestion and throw it in the dumpster?

          The dumpster idea sounds good to me! Or u could just remove the fuser assembly and have a general look-see. Just unplug from mains, remove left panel, fuser knob and the two screws that hold the unit in place, two connectors and it just slides out. If u don't like what u see, the machine will be lighter, enabling easy transport to the dumpster....

            Jammomatic

            The other name for this model of Canon is "Jammomatic". This machine can consistently jam almost any type of media from any paper source. If you do get it working as well as possible, it's still not much. I vote dumpster. =^..^=

              Took the fuser assembly out , the rollers both look pretty old and crappy, will try and replace them to see if thats what was making it heat up and the burning smell

                Make sure that the film on the thermistor is not torn, and its clean and contacting the upper roller. =^..^=

                  Contact seems to be fine but rollers themselves look very corroded. Could that have something to do with the overheating?

                    Typically no. The only way that a worn upper fuser roller can contribute to an overheat condition is that a toner coated fuser roller will tend to wrap paper around it. The additional layers of paper on the roller act as insulation. Additional heating is required for the thermistor to detect the desired temperature.

                    Another thing to check is to the fixing fan is running (squirrel cage directly over the fuser). It's a two speed fan, and usually begins to stall during idle (low speed). During copying the fan goes to high speed, and may start up. Often these squirrel cage fans get packed full of dirt. An excellent way to ruin a squirrel cage fan is to take your vacuum hose, put it up the the squirrel cage and over-rev the fan. The squirrel cage which was balanced will bulge at the center, hit the duct, and be thrown out of balance. The same goes for compressed air. A better way to clean the squirrel cage fan is to remove the cage from the housing. Clean out as much dust as possible with a brush while it's dry. Then warm water, toothbrush, & dish soap will clean up the rest. Obviously, do not submerge the motor. When reassembling clean & oil the bushing on the side opposite the motor.

                    Though its uncommon, the thermistor may be giving a false reading even though the orange teflon tape is intact. =^..^=

                      Thank you I will have a look at that fan. I can guarantee nobody has tried to clean it out but it may have quit, and that may automaticly trigger the e000?
