ColorQube 8870 error 94,536.00

[jlh]

Hi,

I was wondering if anyone has experienced the 94,536.00 on a ColorQube printer before. All Xerox's site has to say about it, is that it is a "temperature based problem" but does not give me any specifics. I have to turn the printer off for about 45 minutes and then it will work again for a few print jobs, but then show the error again. I have the printer in a well ventilated area and the temperature of the room is within operating temperatures.

Thanks,

Joe

That error is referring to the Drum Heater being Too Hot. First thing it to make sure fans are running and none of the vents are covered up. That s the basic troubleshooting you can do. Anything more will require a technician to troubleshoot your machine for the exact cause. The fan / vent I was referring to is on the right side of the machine.

Is the room humid?

Thanks jroth,

I actually was able to get a hold of the service manual. In this manual it has me check the resistance on the Drum Temperature sensor. I have found that the drum temp sensor is not giving me any resistance. I am going to replace this part first. Then if that doesnt work I will need to check the drum assembly itself.

Just in case someone else runs into this problem,

I was able to fix the printer by replacing the Thermistor. According to the Service Manual I should have gotten a different code for problems with the Thermistor, but I think I didnt because the Thermistor was still working but only was showing about 30ohms of resistance when it should be getting 280ohms. When the printer is warmed up it should be getting 50ohms, but when off 280ohms. The part number for the thermistor is 930K01380 and it costs about $50. We had it overnighted and had the printer fixed very quickly. I do applaud Xerox for making the ColorQube 8870 easy to take apart. Only problem I had was when putting the screw back in the new thermistor. The belt wheel for the drum gets in the way a bit so this can be a bit difficult. I had to have someone hold this for me while I put the screw in.

I also wish Xerox would be more helpful in fixing this probem. No one at Xerox was willing to tell me what this exact error meant. I had to get a hold of the Service Manual to get any real direction in fixing the problem. If someone would have just been willing to tell me what parts might be broken and the simple resistance check to test the part.

Thanks,

Joe

Hi Joe,

I believe my 8870 has the same problem.

For $50 it's worth a try.

Once I open the printer will it be obvious how to replace this part? Or can you provide some guidance?

Much appreciated.
