Those codes are related to an abnormal toner to carrier ratio. If you are getting multiple errors that could be a control board failure. I will consult Konica Minolta Solutions and post futher as the information becomes available.

Black smudge when printing color

Imaging unit is the problem. It's made for 100k but often there is a problem very soon after replacing. There is a belt in this unit and he has a lenght enough for two pages A4. Thats why you have problem on every second page. Try to reassembled it and see what is wrong inside ot imaging unit.
If you ask new mashine. This one have a hundreds of problems by default.

Black image streaks on sharp 2700n

You only have to make single color copies with each color CMYK
and check all the copies if only the black and white copies is smeary
then replace only the black the drum unit.

Phaser 7300 dn prints full yellow color background on every page even if the background copy shows no color.

Most likely the yellow drum unit is causing that problem. The charge roller gets worn and makes whatever color it is in print out all the time. That would require replacing the yellow imaging unit.

Printer shows no errors

Is that problem just for that color black? sounds like you might have a bad image unit or developer. You can start out by switching the image units.. switch the Cyan image unit to the Black and the Black back to the Cyan. Print out a solid color page on the trouble shooting menu. If the Cyan prints out bad you have a bad image unit . If Black still comes out splattered then it might be the developer. We always call this company called for support and parts instead of xerox. They have good techninicians. Almost all my answer have come from here. well good luck

Copies and prints in color are black procesed, but in black are ok

Using CMY Color produces a Processed Black.
Using only K will produce a Black.
In the print driver on a PC change your default setting to Black, from the machine you can set it to use only black as well.
That Patch is on the transfer belt. which it will alwyas do, that is what color machines do.

Install the print driver twice and set one driver s Color Mode to color and one to greyscale. This setting can be accessed by right clicking on the print driver and selecting Printing Preferences, click on the Color tab and set the Color Mode appropriately.

How do I reset the ink levels?

Well, theres the problem. Most printers can remember up to three cartridges. That includes color & black. The best way to put it is that each cartridge has a"funger print" that the printer can read, and estimated ink levels can be gaged. There is a way to "reset" the cartridges, but i do not have the document on me. Please email and I'll send it today. I'm not saying it will work 100%, as the reset method is geared for the 56/57/58, but who knows right?

Background Color

1) In the Applications Menu on your copy screen there should be a option to turn on or off a background color fill. Turn it off and try. If it still comes out try hitting panel reset. If this doesnt work. 2) You have a bad Image Unit. Change the yellow image unit. 3) You may also have a bad write unit. Pull out the four write units and check the yellow write unit. It may have gone bad in which case it needs to be replaced.
