Minolta 2050 with ATDC set as 140 and current as 0%

My minolta machine prints with dark background. initially it was printing light but after adding a little quantity of toner to the drum it started printing good color but the ATDC set which was initially at 140 against 6.0 can now be adjusted lower than 140 but the current still remained 0%. i was forced to run F5 and it shut down with a C00f31 code. and the dark background still remains. pls assist me with repair tips. tanx

How to remove dark background on bizhub 350


Make multiple copies of Jet black print for example, open the platen cover and then make blank copies.Print out will be jet black.After about 60 to 70 copies background will be adjusted, if not then replace the toner.After replacing the toner if the background is still there then you must replace the developer.

Tiene codigo cf-033 la copiadora modelo di-450


you have two different models listed .Well for the Di 450 _CF033 error
Description:
C0F33.
Solution:
Check to make sure that the ATDC value noted after running F8 was entered as the "set" value in the Adjust Mode. If the ATDC "set" value was correct, check the connections between the PWB-A and the ATDC.
To check the ATDC "set" value follow the procedure below:
1. Enter the Tech Rep. mode.
2. Press the stop key and then the start key
3. Select printer.
4. Select ATDC reference value. The current value should be close to 5V and the set value should be the same voltage setting as the current. If the value is found to be at "0V" the ATDC setting was not set properly when new developer was installed.
Note: When installing new developer, make sure that the toner hopper and sub hopper are empty. If not, extra toner may be added at the time the ATDC reference value is set (during F8 process). This will cause light copies. please send more feed back on di 183 problem

My brand new machine Bizhub 211 have paper jam problem


COF32 means the ATDC sensor has detected some unusually high or low readings.
The ATDC sensor measure the toner lever inside the developer unit.
Try swithcing on/off, open/close the front door to clear the code.
If this doesn't work, you'll need an engineer to reset the ATDC level.

Good luck

Our bizhub-250 receives a C2557, need help with service mode


Utility/Counter -> Details -> [STOP][0][0][STOP][0][1]
Go to counter and clear the life of the developer and drums and then run F8 from functions.

Dark background print in minolta EP2050 mach.


Replace controller/ interface board. The next step would be the regulator board. If you must keep resetting the ATDC and receive different values ( assuming that the ATDC is new) then the problem is back. What supplies/ controls the ATDC? The controller, but forgive me if I am wrong, there is a small interface board after the controller that the ATDC is plugged into.
