develop ineo-250 Error C2557 error develop ineo-250 C2557 how to
remove how to enter servic mode plz help meC2557 ATDC Sensor
Failure The scanning value of the ATDC Sensor is lessthan 7 % while
the IU Motor is turning. The scanning value of the ATDC Sensor is
morethan 19 % while the IU Motor is turning.
In my experience, the amount of Developer/Starter in the tank is
low.Change the Dev and run F8 in service mode.The post above
relates to the mono ineo 250.
Just noticed you may be talking about the ineo+ 250 which is a
colour machine. If so:
C2557 Abnormally low toner densitydetected Black TCR Sensor TC
ratio in the developing machine, which isdetermined by Toner
replenishing amount controlmechanism, is 5 % or less for a given
number oftimes consecutively.
Run the Black TCR Toner Supply from service mode. If this
doesn't fix the problem, change the Black Imagining Unit.hi..as i
recall there is a a reset sw on the board at the rear side..service
mode....(utility+details+stop+0+0+stop+0+1)i hope it is help my
dear...You need to get into service mode and look at the K toner
ratio. If it's below about 7% the K toner add system should be
trying to add toner. If its down to around 3-4% you might have to
reset the 2557 code several times to allow the % to rise enough to
satisfy the monitoring system. You will not be able to add K toner
through service mode until the % gets to the minimum level. If you
have a full bottle of toner, you may have a problem with the toner
bottle motor, or there may be problems with the hopper assy. Poor
connections at the PRCB can give this error. I had one on a C652
that was caused by the hopper harness not connected to it's
connector on a brand new box. EmujoEmujo, we still don't know if
it's the C250 or mono 250 tariq65 is talking about.
tariq65, if you could clarify the machine model number we will
be able to help you further.Just reset the pc life and run F8, code
2557 will reset. You will reset the pc life while the right door is
open or else anoying buzzer will come everytime you turn ON the sw.
I hope you know the right procedures on resetting pc counters. Then
add little toner on developer and run F8. Some tricks you have to
do in here.... Little dark copies are expected but after a week or
two the copies will surely great!
have fun...Reset it, start it with the right door open, go to
service mode, clear the counters for drum and developer and go to
functions menu. Close the right door and start immediately the F8
function. It should workerror C2557 - Bizhub 250DescriptionC2557
(C-2557).SolutionCAUSE: The drum was replaced without replacing the
developer.SOLUTION: Replace both the drum unit and developer at the
same time. Once the code occurs, developer must be replaced to
properly recover.The correct procedure for replacing the drum is as
follows:1. Select Tech. Rep. Mode => Counter => Special Parts
Counter => PC Life.2. Press the Clear Key to clear the counter
value.3. Turn OFF the main power switch.4. Open the Right Door.5.
Remove the IU.6. Remove four screws (silver) and disassemble the
Photo Conductor Unit and the Developing Unit.7. Replace the Photo
Conductor Unit.8. Remove three screws and the Developer Scattering
Prevention Plate.9. Remove the Toner Supply Port.10. Remove the
Developer.11. Set the developer while rotating the gear in the
direction of the arrow.12. Reinstall the Toner Supply Port.13.
Using three screws,securethe Developer Scattering Prevention
Plate.14. Install the four screws to secure the Photo Conductor
Unit and Developing Unit.15. Install the IU in the copier.16. Turn
ON the main power switch.17. Select Tech. Rep. Mode => Function
=> F8 and press the Start Key.Notes :a. After replacing the
developer, be sure to execute F8 under Function of Tech. Rep.
Mode.b. When the main power switch is turned ON, execute F8
quickly.
