[Error Code] C2557 on BizHub 200

[jjohnston12385]

Hey guys, I've got a problem machine that I was on for several hours today and drove me insane. It is constantly throwing the above mentioned error code no matter what I have changed. I just replaced the drum/developer/developing unit last week, cleared the counters and ran F8 in the function menu. All was fine til yesterday when the code popped again. For testing purposes, I replaced the 3 components again and when I ran F8, I noticed that the toner bottle wasn't spinning. I removed the toner replenishing drive unit and cleaned the two solenoids with luck. I replaced the pwb board in the rear of the machine and that had no effect either. At this point I'm completely stumped and don't know what else to do. I ordered a sub hopper assembly thinking the sensor could be bad there but I don't have a whole lot of faith in that being the culprit.

Thanks in advance for any/all help!

Re: C2557 on BizHub 200

a) see if there is drive to the drum, it may not be turning

b) order those solenoids you cleaned

c) yes the sub hopper has a reed switch that triggers the toner add solenoid, order that

the toner bottle doesn't necessarily turn when you run an f8 so don't get fixated on that

Is there a way I can test for drive to the drum? I can't run any test prints because the code pops instantly. I know the main drive gear assembly was replaced within the past month so I'm pretty sure it's turning. I'm going to get those solenoids on order first thing in the AM along with a spare reed switch for the sub hopper.

To see what is turning, mark everything with a black marker and see if it moves. I would also look to see if the counters reset when you zeroed them. It should run F-8 without adding toner. If it needs toner, it will add after F-8 is done.

the solenoids 1 and 2 have to be replaced not cleaned.

ON the main board there is a little black button. Press and hold that down, it generates an internal test chart of lines. This will tell you if things are turning.....

Re: C2557 on BizHub 200

Just to give an update on this situation. Me and another tech have been battling with this machine for over a week now. We have changed the Drum/Developer/Developing Unit twice, changed the entire sub-hopper assembly, the sensor on the sub-hopper, the main board in the back, the M5 fan (on the right door behind the registration section. We were able to get the code to clear once. We ran ~600 copies and it popped the code again and have yet to be able to clear it this time. Even just running F8 fails. I went as far as reflashing the firmware, and that did clear the code for about 10 minutes. But after 2 copies, it popped again.

I tried pressing and holding the black button on the main board, but after about 5 seconds, I get an abort code and the machine reboots itself. Everything is turning as it should be based on marks I put on certain gears/parts. I am on the phone with KM tech support and the gentleman is having me go through lots of settings and values with him.

At this point I would swap the MFB3 with one from another machine.

I take it you are referring to the board that sits under the scanner optics?

Yes, That is the main brain.

replace the drum and dev (again), fire it up with the side door open, get into service mode>counters, reset the drum and dev count, then exit out of service mode by ok-ing everything. then go back into service mode>counters and check the drum and dev count. if it's anything other than 0 reset it again. without quitting service mode, close the door and run f8. ok out of everything, run a few copies, reboot it with the main switch at the back. you have to replace drum and dev together, and you have to make sure the counters are clear. otherwise you get this code.

[jjohnston12385]

That is exactly how I've changed all developers and drum on this series. Including the two sets I've put in since this problem surfaced. So I know it's not that. I've got the two solenoids on order along with another sensor for the sub hopper and a whole new hopper unit as per KM tech support. I'll try a different MFPB from a known working machine and give that a go.

Re: C2557 on BizHub 200

Before you do anything else inspect the solenoid (that others have mentioned) that works the actual clutch that brings toner to the DV unit from the sub hopper. I have found that as the solenoid gets older it will intermittently latch/stick and cause toner to be added and drive the toner ratio out of range. Good luck.

Re: C2557 on BizHub 200

I have read time and time again that one inspect or clean solenoids. to me, it's just not true. solenoids are by nature clean as a whistle.

sometimes they have little pads that wear down or stick, but the plunger and magnet are not the issue.

if they don't fire replace them.
