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

I don't have a Xerox, but my previous HP and Samsung and current Samsung have on-screen Windows-configurable settings for adjusting darkness etc.
Open Start>Control Panel>Printers and Devices
Right-click the XEROX icon and choose Settings.
Browse through the menu pages until you see a page with similar to the screenshot.
May be called Advanced.
Darkness should be normal, or if still showing, try light.
ECO mode should be On.
That fact that other printers are not printing the noise means that the current user-settings of your XEROX are too dark, thus reproducing the pixels of the signature graphic.
If you selected a pixel near the signature and analysed it in MS Paint, you'd probably find that the 24-bit RGB value is not pure white 255.255.255 but maybe a few steps darker, say 254,254,254.
To the human eye this would be hardly noticeable, but the printer may be darkening the pixels even more, causing the noise.
I wish you luck in your noiseless quest.
Open the printer driver setup window Select the manual color adjustment (or if already in manual and it had initially been printing fine, you may opt to select Auto) On the Main tab, select Manual for Color/Intensity, and click Set.... The Manual Color Adjustment dialog box opens. Specify the brightness
Select Light, Normal, or Dark for Brightness, and click OK. The current settings are displayed in the settings preview on the left side of the printer driver. Complete the setup Click OK on the Main tab. When you execute print, the data is printed at the specified brightness.
you have two different models listed .Well for the Di 450 _CF033 error Description: C0F33.
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
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.
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.
