Hi,

I have a C224e at a customer that suffers from C2557 after just one week,

so far i have only changed the black developing unit but this has not resolved the problem, before i start replacing boards etc has anyone had this before??

any help would be great.

Hi,
I've got the same problem with 224e. After c2557 toner level is 0.5%. I did perform Manual Add Toner. Toner level were 6% but it's were for a while. After few 100s pages problem return. Any sugestions. Developing unit exchanged. Manual toner adding works fine.

We work on olivetti product and there is now a bulletin of a known problem and fix, if you are a KM dealer the info is the same and the part number for the bushing is A5C1RA0000

Just wondering what the outcome was if you did find one. I have one doing exactly the same thing and i have replaced the toner hopper supply unit at the front of the mach and am going to change the complete toner bottle drive assy at the rear.

hi
I have faced this problem in 4-5 machines.
First remove the catch tray and do manual tone up for black & see if toner bottle is rotating correctly.
Next remove toner hopper and check black toner section for damage gears or jammed gear system (Remove toner dispensing motor which is only for black)
refit toner hopper correctly, in all the cases refitting of toner hopper solved the problem.
Good luck & hope this solves the problem

AkitN thanks for your help. My first step i replaced black dev, then i reseated the toner hopper assy, then i replaced the hopper assy. I have opened up the cover and when i do a forced toner black it recovers to about 6.4 give take. We also had another mach which did the same and all we did was reseat the hopper. But this one didnt fix with this fix. Next step is toner drive assy at rear cause on two occassions the drive prong for black was not engaging the black toner bottle

Hi,

Have you tried hovering out the belt and all the drum units?

There is a sensor behind the belt that on the actual machine that will require cleaning aswell.

May take more than one go, just stick with it.

Good luck

Toner level sensor float actuator in the hopper pops off the plastic post it pivots on at the back inside of the hopper.

Hopper will never refill when empty, TCR will go till 0% then error.

Later version hoppers allegedly revised, however, this is one i changed a month ago.

Joke of a design, same shit happens to all 4 colors on all 4 series - 224 - c554E

Easily corrected with a thin hook.

Always check before installation of a new hopper, can dislodge in transit.

I have replaced the whole sub hopper assy at the front of the machine but just assumed it would be ok as it was new. I will have to check it out next visit as its still not working right. You dont happen to have any other pics or a part number of the failed part?
