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.

Fix a xerox 6350DT


If you have a white stripe in only one color, then you might have a bad developer. Each color has its own developer
116-2008-00 Yellow
116-2009-00 Magenta
116-2010-00 Cyan
116-2011-00 Black

Changing the developer is not super easy. You'd have to remove the left cover, HV Power Supply board, then remove Image Unit and the Developer Frame, where all the Developers are mounted. Detach the feed hose for the Developer you want to change and release the Developer's 2 spring clips.

The attached photo shows old developers which have dead spots that would cause the missing stripes on prints.

Print appears on multiple pages


check the fuser unit in the back of the machine; typically the shadow effect is caused by the fuser assembly. Inspect your toner cartridges for any leaking toner. Genuine HP or ? ? ? ?

Savin c4540 printing blue stripes down the left side of page


Looks like the drum unit is going bad or the xerographic module depending on which on you have but both develop the image and transfer it to the page. Pull out the unit and see if there is any lines or damage on the drum module which will look like a brown sheet of film or be a small roll usually green or blue in color.

I have a Xerox Phaser 6100. I just replaced the imaging unit and the transfer belt. Now my copies are coming out with lines across the whole page. one page that I printed came out wiht all colored lines...


Try doing a "stop test." Stop the print process at various stages, and see if which component creates the defect.
For instance, if a print takes 20 seconds, during the first 10 seconds, the drum is generating the image to transfer to the belt. If the image is bad on the drum, then that is your culprit. If not, then see which unit creates the problem.

Also, what color is the line?
After the unit gets to the transfer belt, you should check the transfer roller and fuser.

One possible cause could be the transfer belt cleaning section. It can get a toner build up on the blade. Take it out and wipe the blade off. The transfer unit is above the drums and the cleaner is on the left side.
