[Error Code] P-21 Printing everything with Yellow Background

[patriciag]

We have a konica minolta bizhub c550 and this has happened before where the printer prints colored pages with a Yellow Background. I called for service but the company that use to service us was bought out, and now the service tech is a bit money hungry. The last guy fixed it 123 this guy was going on about oh it could be this or that, but said replace the IU which I just did and it is still printing with a Yellow background.

if anyone has any other tricks because our old tech did something (should have paid attention) and it was much more cost effective then even buying a new IU, would be so greatly appreciated you have no idea!

thanks!

Make sure the IU are all in correctly as well as T/belt and make sure all sensors are clean. Also try running calibrations. Check the consumable life if items are over life its better to replace and get everything back into spec. I don't believe in tweeking settings, it might work temporarily but will end up worse than when u started. Might just need a good clean

I had a problem with yellow vertical strips about 3 cm in the top and the bottom of the the page. A compromise solution was by setting the output tray on the long edge. I changed the magnetic roll and resolved

Re: P-21 Printing everything with Yellow Background

Hi
I have the same yellowish page on C554e. I am using refill toner from TN622. I changed the dev unit I worked for a while and now is giving me the same yellowish page edge to edge.
On other machine I use the same toner, same enviroment and it is working properly.
Any suggestion?
