Does the demo page do the same? Mite have image control board failure. And electrical storms on a good surge protector not a Ace hardware 19.99 special, of course nothing against Ace Hardware :). Could also be a High Voltage board failure. Meter count page OK print out.

i think that your fax is not set up right, or maybe the machine is missing admin and machine e-mail address, that can cause too this problem.

I have a Konica C250 machine which cannot print red color at all. I had changed the toner and image unit but still cannot print red color. How can I solve this problem?


Recommended that you have a tech come out and look at it might have a bad LED assy. for the Magenta Image unit. All other color print OK? Can you print gradation test pattern for each color in service mode? Meter count, details, stop 00 stop 01 Test Output Gradation pattern select magenta. If you open the side cover after printing a document with the color magenta try to catch a print of paper do you see the color magenta on the transfer belt if yes the drum is ok could be the transfer belt magenta 1st transfer roller on the belt replace the belt assy.

Malfunction C2553


Open close front door to reset. But your Magenta Image unit is having issues remove and shake the unit side ways to spread developer and toner whole length of the unit. Worse case get a new magenta image unit.. Also clean the sensor below the image unit when pulled out all the way near the front of the copier each color has one except black.

Error code c-2833


CAUSE: LD Power becomes saturated when performing Auto Gamma adjustment in a low humidity condition.

SOLUTION: Perform the following adjustment:
1. [Utility].
2. [Machine Admin. Setting].
3. [System Setting].
4. [Expert Adjustment].
5. [Process Adjustment].
6. [Toner Quantity / Exposure].
7. Select the proper Exposure Adjustment [Yellow, Magenta, Cyan, or Black] by using the Next/Previous button.
8. Select Standard then select [-2] under Exposure.
9. Press OK.
Notes:
a. If the problem persists, replace the problem color drum since the cause of the SC is the combination of drum characteristic and humidity.
b. The following codes = colors: C-2831 = Yellow; C-2832 = Magenta; C-2833 = Cyan; C-2834 = Black.

I have a Konica Minolta Bizhub c351 and all of a sudden it started printing everything with a pink hue and the colors are very uneven.


There is a long process to solve the problem I might suggest that you have to call for service. It might be the magenta developer unit might be bad or rich the max life that need to be replace. Or just plain adjustment on colors setting. It might need to update the firmware to the newest level.

sounds like the wrong image unit. Oce and ollivetti have the same machine and take the same image unit but with a different chip. Make sure it is a genuine konica minolta image unit. If need be try putting the chip from the old unit on the new one and see if lays down the colour
