Re: Yellow dosent work ok
Theres a service code to run the calibration program to reset the colors. It should be ran by a technician because that machine is very picky about running the procedure the right way. If someone shortcuts it, it makes a big mess.
With three error codes on the screen, it won't be something easy on your end to clear it.

This may be a reult of the drum unit going bad or serveral sensors going bad. How many copies does the yellow drum have on it? Warranty is for approximately 40,000 prints.

Imaging units for Minolta Bizhub and CF series. http://www.chipreset.eu
If you let the yellow toner get to the point where the toner cartridge was totally empty, there is one thing you can try which may help. From the "menu", select "maintenance", then go to "clean developer" and choose the yellow. The machine will then churn for a few minutes. What happens is there is a tube that moves the toner from the toner cartridge down to the developer unit ( which is behind the imaging drum). If the toner was allowed to totally run out, there is an area of the tube which may have little or no toner in it. Each time you print, there is a spring auger within the tube that draws the toner to the developer. By running the "clean Developer" it turns the auger and re primes the tube.
If this does not fix the issue, and you have replaced the imaging unit, then the yellow developer is defective and would need to be replaced. This involves quite a bit of work and is not considered user replaceable.
