C4-00

[woko]

Hello fellow tech's. this week we have had 3x machines report fault code C4-00 (ptc fault) two of the machines could not be repaired on site and were brought back to my workshop on both occasions, all I have done is re-seat the TC board and all has been fine, however I have not been able to find what's been the cause of the problem, anyone else had this problem, we are based in Birkenhead UK.

Yours Woko.

You might want to check the power coming in to the machine.... I've had flaky power cause random E-codes on machines before. Also got this info from a "C4 Countermeasure" Tech bulletin from Sharp. You didn't specify which model you're dealing with.



1. Model Name: MX-1810U/2010U/2310U/3111U, MX-2610N/3110N/3610N, DX-2500N/2000U,
MX-2314N/2614N/3114N/2615N/3115N/2616N/3116N, MX-2640N/3140N/3640N


2. Symptom: Trouble code such as ”C4-00” or “L4-06” may be caused in some rare cases due to the
joint failure of the clutch mounted to the main drive unit.


3. Description: To prevent the clutch from the joint failure, BK drive frame, belt clutch shaft, and belt
clutch CCW have been changed in shape. Along with this change, E ring has also been
added.
