[Error Code] Konica Minolta BIZHUB PRESS C 1085 - C-2731 Error

[subhan]

Hello,

We have supplied Press C 1085 to one of our customers like 2 years ago, ever since we supplied this machine and when the DRUM unit reaches between 40% - 70% it brings this code of C-2731 , 32 ,33 or 34, which is for 1st transfer neutralizing error for YMCK.

We understand that the Neutralizing charger attached to the DRUM is having an issue, Many a times we clear the Charger and swap the drum units and it works for few a days then brings it again. Also we think it could the moisturizes which is on the charges to fail, because this error usually comes in the morning hours on the 1st start, it never appeared during the day or while printing, at one point we thought the machine direction towards to the Air Conditioner maybe brings this issues, so recently changed the direction of the machine from AC and changed all the DRUM units, which worked fine for little while and now it is has brought an error for Yellow (DRUM life is about 45%)

So for we have changed 3 DRUM sets on 40% 70%.

any advice please

Regards

Do you have another same machine to try that old drums are they make same errors ?
If you have another machine i also would try replace HVPS/3.
What humidity machine shows on display,try to keep track of humidity and temperature in the morning and during day if it have influence on error ?
