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

[tradewynnes2]

Got some information from KMBS on this issue. There is a FOC part, bushing kit, they suggest to replace. We just ordered these parts today. If it works, I will let everyone know.

Cheers for that tradewynnes2

We had a c224e dumping a small amount of cyan developer. It was enough developer dumping to get down onto the cyan optics strip and give us really crappy color copies. So, located on the outside of the developer unit just below the mag-roller is a thin mylar strip. That strip was bending inward scooping the developer out. We just ripped the mylar completely off of the developer unit. Seems to be working fine now.

I've had that mylar do the same on cyan imaging units in the C452 series too, and every series all the way back to the c350 - probably happened on CF2001/2 machines too but they were popular before my time.

I believe thats a transport or handling issue and the initial mountain of dev at one end of the roller will start this off.

It also happens on poorly handled C451 Black imaging units too.

Thanks for this Trade but i have rectified the copiers that have the codes with the above mods the other issue is that the Cyan dev is drained out of the units with no codes and the levels are all correct. This is the problem that is confusing me more.

The bushing repairs held with no issue for about a week, now we are having very light prints. The KMBS rep is going out to look at it with me today. Will update if any solution is found.

The toners all contain developer, so, the dev that is leaking is being replaced by the dev in the toner bottle.

Ok, so, I don't know if this will pertain to everyone elses machines, but what I finally found on ours is the developing units, when they were replaced, were jammed in and actually blocking the shutters at the bottom of the toner hopper, obviously causing no toner to get through. One day it was just the black having the issue, then after a couple of days the cyan came up. Once that was found, the other colors were jammed and had to be fixed also. It has been about a week with no more calls. Again, not sure if this is the problem with anyone elses machines, but this seemed to solve our problem.

Hi there i am from South Africa and I've got almost a 100 c284-c554e in the field...also experiencing the same problem.Developer wasted and ending up in the waste toner.But destroying at times transferbelt and drums.Also swapped hv boards and tried different machine settings ,firmware and made sure toner supply working properly but no luck.
I also think this could be a bias related problem...funny... at first all the other people thought i was crazy when i told them about my predicament but soon started experiencing the same problems with no solutions as yet.....And worst of all we dont struggle with just the cyan but all colours...
Sitting with 3 machines that made less than 50000 copies in total and had to replace transferbeltunit,all drums and dev units and another thing that i picked up most of the trouble makers is the e range...
But i also think the culprit could be that front relay board as "Earthkmtech" mentioned and changed-Qouting:"What i did on last call;

New mfp & total initialize & latest fw.
New front relay board
Vacced cyan hopper and new toner bottle (last one fitted for all failed units)
Cyan density set to -1 for copy and print
Stabilization mode set to colour priority."

FRBoard.jpg going to order one tommorow and test ...this problem is frying my brain

This is what my parts look like when the reaper gets in my machines ...actually something to cry about loosing thousands of potential copy clicks!!!

If someone gets a solution before time please inform us ....

PS- The amount of developer lost at one time will never be replenished fast enough by the toner adding system....

If you are from one of the branches take it down to the training centre and ask if they can have a look at it.
Did you get any rust and corrosion in the machine. The C360 kicks out its developer if those springs are rusty.

What branch are you from?
