My printer prints black pages perfect, when attempting to print color my yellow is out of line by 2 mm, so I can not print green , orange, or any color that needs to be mix with yellow, I have bought a new set of drums and a transfer unit and the problem remains the same.
When you try to calibrate through the menu, it fails and this message comes up,error occurred sc285, functional problem, turn main power switch off then on if error appears again, call service.
it there a way to manually adjust the yellow color by 2 mm left or right, has any one experience this sort of problem before how was it solved. please email me a link that I can get a service manual download.

SC285 is a line position adjustment error. It is possible the ID sensors are dirty. In order to get to them you have to remove the PCUs and developers as well as the transfer belt assembly. The sensors are behind the shutter that is next to where the upper most PCU would be inserted.
No way 2 override the message.
Printer works on a combination of both black and color ink to print those perfect pictures and documents.
If it is showing color ink needs replacement,you ve 2 change it in order to print even in black and white.
It will be extremely difficult to provide any solid trouble shooting tips not knowing the type of copier (Manufacture’s model number) or the type of technology that your copier is using (Laser vs InkJet).
I can offer some common logical trouble shooting which I hope will assist you in your fault isolation process.
1. Is there ‘pattern’ to the ‘light line’ symptom?
Same location on each page then it occurs?
Is the number of pages between occurrences the same?
Occurs on text only; Occurs with graphic material
Is it a ‘full’ line or part of the line?
2. Does this occur with both Black/White and Color print outs.
Some software applications will use the color cartridge to print the color Black as oppose to using the Black ink cartridge.
3. Does this occur when using a specific application?
4. Are you able to determine a MTBE (Mean Time Between Events)?
If so, then you can reproduce the symptom and attempt to isolate some of the variables I have listed above.
Again, we need to know the make and model of the unit in question to be more specific.
What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem. You can try googling. Phaser printer print heads or phaser printheads. There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head. Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads. Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP. The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.
when I opened the front door to the cartridge compartement there was a green line of toner on the feed belt, I wiped it off. then I slightly closed the door to open the toner cartridges and found the one creating the mark and cleaned it.
no more line
