    [Error Code] H3-00 on AR168S

    Hey guys,

    We've got a AR168S throwing up H3-00. Of course the first thing (other than just resetting the code) we checked and decided to replace was the fuser. It worked for a week or so and then coding again. One of our senior techs suggested to replace the MFP board which we did. Again worked for a short period of time and then same code. By now we have done a full PM, cleaned and tried to figure this out. And yet it is still Coding. The environment is clean and the temperature and humidity is fine.

    The customer says his building had a big built in surge protector that protects all the lines which I don't really believe but just thought I should note this in case it helps anyone in helping me

    Any ideas?

    Thanks in advance (no cash sorry)

      try to open the fusing unit and look at the heater lamp, possible heater tungsten was melt(clouded with brown color) and generate more heat at fusing part.h3-00 ---->thermistor over heat was detected

          I will double check this next time I am there. We had checked this first and replaced the fuser with new (not because it was the fault, rahter, that the fuser needed to be replaced any ways). Thanks for the response.

              Check continuity of heater triac on power suppy PWB.

                      Have you tried sim 5-02 to see if the lamps are working properly? If they stay on constantly (don't blink) then it may be a power supply issue. Do you have a surge protector on this circuit? Have had some weird symptoms/problems when there are 2 surge protectors on the same ciruit.

                      Good luck.

                          We have tried it with and without our standard "plug-into-the-wall" surge protectors. I will check again the lamp blinking with the sims.

                          By power supply you mean the power supply unit int he machine or the supply fromt he wall?

                          Thanx Bil,

                          hope I can figure it out this morning.

                              Sorry, never H3. Plenty of H4, though.

                              How about fan operation and environmental temperature. Have you ever been present for the code occurrence?

                              The reason I ask is that we need to determine if it's actually exceeding 240C, or if it's a false code (inaccurate detection). If you can catch it in the act you can use a temperature probe to monitor the actual fuser temperature.

                              Keep in mind that this group of models let the fuser temperature vary broadly, especially when entering energy saver, or waking up from energy saver. This might sound crazy, but see if you can shut off energy saver and auto shut off. Some models will allow you to do so. =^..^=
                              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.

                                  I agree with Blackcat, also check to see if there is anything else plugged in the same outlet the copier is plugged into.

                                      If the lights stay on steady when you do sim 5-2 then it would be the power supply of the machine. But blackcat has a very good point. Have seen some units have problems when they come out of sleep mode or auto power shutoff and get a H3 or H4 code, especially when they are both set to the maximum time limit (normally 4 hours). This seems to be especially true when they leave the machine on all night then have to turn it off and on in the morning to restart it, then the error code will show up.

                                      Good luck.

                                          I check this machine again yesterday. Using sim 5-2 the lamp stays on. Was in the middle of acquiring a power supply from a good used one we had here when I was notified that they had opted to purchase a new replacement one through our sales team.

                                          Definitely looks like it was the power supply board but not totally sure as we never got it fixed completely.

                                          Thanks for all your help.
