MX-M5001N

[mikeg1265]

Hello,

I have an MX-M5001N throwing an Error Code C4-00 which is a PTC error. We recently changed the drum, blade, fuser, and Primary Transfer Belt. The error started to appear after the PTB was installed. I changed the the PTC unit at the same time I installed the PTB. I can't seem to figure out why it's throwing C4-00, I've inspected the belt and PTC unit but I can't find anything wrong. If I clear the error code the copier works fine for a few days and then throws the code again. I've worked on a lot of Sharps but this one has me stumped.

I seem to remember there was a problem with the environment (humidity/heat) that was causing this code, so maybe one of those sensors is bad.

Re: MX-M5001N

there are several bulletins on this error. Sharp did change the ptc ass'y. Maybe you have the old style. A couple other bulletins are for noise C4 code also.

have you clear the ptc counter?

Ahhhhhhh, now that's an idea. I wondered if the style was a little different. I'm gonna try putting the old PTC back in.

Re: MX-M5001N

I'm not looking at the bulletin right now, but I'm pretty sure the changes were mostly elongating the spring for better contact and less C4-00 codes.

Someone please correct me if I'm wrong.

Re: MX-M5001N

FYI: Incase you did not know. You can disable C4-00 by setting Simulation 55-1, soft-switch 8 bit 3 to "1" (until you get it figured out)

C4-00 Error Code in the display.
Cause:
There may be a loose connector to the PTC unit on the rear frame. This wire is coming
from CN2 on the Secondary Transfer PWB to the PTC on the rear frame.
Solution:
Slightly crimp the connector that is plugging in
to the PTC unit. If this connector is not a
tight fit there could be intermittent C4-00 error codes.
