That's what the guy did so what do you want to say Victor285??

Doesn't matter now, as he replaced unit. Trouble reset is timed with rather short window for resetting or it continues cycling. 3, 00000000. trouble reset, exit.

I sold the customer a Ricoh Aficio MP2550. I have not picked up the 250 yet. Will do so next week and maybe continue to try to fix it. Thanks for all the help. I will post results when finished or if a new situation arises. Frank

You can manually adjust ATDC gain in smode : Tech. Rep.Choise ->Printer->ATDC sensor Gain.Take a look what is the current value and play a little with the values between 170 and 185 after you replace the broken gears, you may get rid of the 2557 code.

I was going to suggest the same,i have pushed it up to 200 in order to clear 2557 code.

Can't get into tech rep mode as it stays in reset mode and keeps cycling bact to dot on screen when you are supposed to press 3, then end, then trouble reset.

Re: Bizhub 250 trying to reset error code

Was getting intermittent C2557 and c2211 codes. Changed both motors and drive unit. The developer motor had badley damaged drive head from dv unit resistance. The other motor had resitand from transfer assembly which was a little gooky. Tookm it apart, cleaned it and lubed. Still getting c2557 and may need to change dv unit. Paper stop when going thru fuser with the c2557 code. Also machine not allow acknowledgement of trouble reset though i see that it is mentioned here to open right side door when doing it which i did not. Can't get into tech rep mode as it stays in reset mode and keeps cycling bact to dot on screen when you are supposed to press 3, then end, then trouble reset. This is getting crazy with time + cost. Wish i had a used machine for parts when i started.Starting to get disoriented. Help!!!. Frank

After you see dot on screen, press 3, then enter access code and enter / exit. You should either get or read the manual.

Also another reason for the C2557 that you may want to take a quick look at. The toner adding solenoid on the toner drive assembly can stick if that foam pad wears off. It gets sticky if it does. See if the solenoid is engage as it will add too much toner to the Dev unit.

It is possible to see this when removing the drum/IU.

It is possible to get into tech rep mode if you reset the code and leave the right door and/or duplex door open. It will keep it from coding out and allow you to access it.

Re: Bizhub 250 trying to reset error code

Thank you Alex. I can try that if machine doen't reset after changing motor and drive unit. Frank

Re: Bizhub 250 trying to reset error code

I did no t change the drum or the developer and I did not reset the counters. The error code C2557 came when the drive motor could not turn.I don'r know why it caused a C2557.Frank

If your drive motor is not driving the developer unit, you aren't getting an induced voltage across the ATDC sensor so the machine fails with the ATDC code 2557. After you get drive fixed, the code MAY go away if the toner/carrier ratio is still good.

Re: Bizhub 250 trying to reset error code

Returned to customer's office today. The C2557 is not a result of changing drum without developer as nothing was changed and no counters were reset. The C2557 came on as a result of a drive problem. One of the main motors has a worn down head and a couple of gears on drive unit are worn. Am ordering drive motor and drive unit for machine. Just don't know if machine will reset the C2557 after installing drive parts.
Am I going to have to change drum and developer even though machine never needed either one or can i reset counters and leave same good drum and developer in machine if code does not reset? Frank

Once you replace motor and since you have just replaced drum/dev, just run F8 mode again. Just make sure drum/dev counter is reset. I have seen on this model that if the C2557 comes back after replacing drum/dev and running F8 mode, you just need to reset through pin hole on RHS and run F8 mode again. Keep RHS door open when you reset. I have seen me run F8 mode several times before it would setup correctly.
