    [Error Code] AR-207 Code U2 40

    3 SHARP replacement toner cartridges installed, code still coming up. Bad crum reader? If so, what should I do about that? I read somewhere you could take back panel off and mess with the reader, somehow..? Tricks? Tips??

      The connector that reads the cartridge is attached to an angle bracket that can bend when cartridges are forced into position, and not all connections are made giving that error. With back cover off, locate the bracket, and give it a push to the right angle to mesh up with the cartridge.

          Did you do a 16 reset?
          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.

              The crum chip reader seemed a little loose, so I tightened the two screws holding it in. Put cover back on, and machine still throwing code..I have tried Clear key Interupt Key Zero Key Interupt Key 16 Print....Code still flashing..

                      See if you can run a developer calibration, if so do that. Also you should check ALL connectors to the main board. I read somewhere that on these models a u2-40 can be caused by electrical noise coming from the power supply, if nothing else fixes this see about changing the power supply.

                          Electrical noise from the AC power. I seriously doubt that somebody with a 16year old copier will upgrade their electrical service.

                          You have to consider on calls like this: How much in the way of repair costs can you charge on a service call when the maximum attainable value of the MFP is $500? Certainly not more than that. =^..^=

                              That copier is probably only worth $25 at best at a yard sale. Noise generated from the power supply causing the problem is very possible, more specifically the
                              electrolytic caps on the board, after 15 years electrolytic caps can become unstable and their values can change dramatically causing noise effecting logic circuits. Old tube amplifiers with failing caps as example will generate a hiss to the output speaker, which is in fact electrical noise. Not saying that is the problem with this
                              case but as these copiers age so do any electrolytic capacitors.
