First check the Laser window cleanliness,
Then check the IU-Cyan and its charging grid cleanliness.

also try in service mode-Image Processing Adjustment-
Background voltage value can be increased.

Intermittent Magenta background across the entire page that fades in from lead to trail can be caused by a failing HV1. Please replace HV1 (p/n A00J M407 01) to correct the problem.

SOURCE: excess cyan toner is on electrostatic transfer

Since you have Cyan toner in places where it should not be then the only possible cause is a defective Cyan Toner cartridge. I worked on one just last week where the customer complained about Magenta toner on their prints. I also noticed Magenta toner on the Transfer Belt just as you see Cyan toner on the Transfer Belt. I replaced the Magenta Toner Cartridge and everything cleared up nicely. The Transfer Belt Unit can also cause similar problems but it would not be ONLY one color like Cyan. It would be a mixture of all colors. My bet is replace the Cyan toner and you will be fine. If you have an old empty one just shake it up a bit and try it as well. This might allow you to verify before buying a new cartridge.
Good Luck and Thank You for using Fixya.

My bizhub c451 is still printing only cyan and black after we change toner catridge, what could be the problem please


The problem could be the laser that scans the image or the detectors that see the colors. It could also be a problem with the power supply or the main board. This is not going to be cheap. If you want to continue, you should download the service manual.

"Konica Minolta C352 - cyan and white pattern background on every print?!


What are you printing a Word document when this happens ?
suspect pattern may be in the software you are printing from.
Go to software help screen and look search for removing background pattern or removing watermark.

Excess cyan toner is on electrostatic transfer sheet even after wiping it. All black and white pages are printed with cyan background.I am even using original cartridges.

It could be a couple of things with the toner, magenta drum might not be taking the toner off, or the transfer belt. The best thing to do is get a hold of the Konica/Minolta Rep in your area.

Fargo Pro-L Not Printing Edge-To-Edge


These direct-to-card printers do not print right to the edge because of the way the print head comes down on the card. There will always be a white boarder on the card especially if your graphics are dense. The only solution to this issue is to re-design your artwork so that the image fades at the edges of the card so the white boarder is not obvious, or purchase a re-transfer printer which will give you true over the edge printing.

Poor registration on Xante CL30 HSE


Make sure the drums are properly seated in their cradels, and if posible, avoid designing with white small text in heavy solid areas that are made up of process colours. For reverse type in a black background, use spot color black rather than rich black. Other than than printing on a not as heavy card, that is about all you can do.
