C224e/C284e/C364e/C454e/C545e cyan dev unit problems

**hotfuser** · 06-26-2015

Guess what ?

i have had another 3 cyan dev units fail this week.

All failing once again between 60k-90k colour.

The one i have had this morning is a C284e which has been in the customer for nearly two years without a problem (maybe the odd jamming issue or a worn black drum unit) then out of the blue (no pun intended) the cyan dev unit has failed.

Will be going back to take it back to factory settings after replacing the unit.

Will keep you all informed.

Have you had any initialised machines re-fail since doing so ?

One thing I have noticed on the c454/554 machines with the toner filter is that the filter is almost always blue when ready to be changed.

I think these machines may just be a modern C352 where regular (IU) failure in certain environments is just to be expected and dealt with. At least it will keep us employed...

None as yet have failed since factory re-setting and re-firmwaring.

I will let you know whether this does happen

Another failure this morning. Copier had been in customers 14 months and its first breakdown call was this morning for PCQ and yes the cyan dev unit failed.

The copier has done 61k colour and 197k black.

oh well that is another to add to the ever increasing pile.

Not sure if you guys have seen this TAD from March this year regarding dev loss?

Yes had that bulletin thank you. That basically is for machines that have done over life all of my machines are no where near life on their parts.

I have to ask what are Konica-Minolta UK doing about this ? Probably nothing as usual.
Is it specification or a fault lol ??
Seriously there has to be a connection issue and a bias drop out, it just needs to be found.
I will do some digging and see what I can find.
