    It worked and made the copy clear but only for about a month and the copies are unclear again. Is it ok to do the developer recalibration several times? What else can I do to improve the copy clarity?

Frequent paper jams with my Konica 2223 photocopier

I wish I could help you, You need to call for service for your copier. An authorized dealer or Konica minolta branch service in your area. You might need a fuser unit that the upper separating claws disloge or broken, exit paper detect actuator is broken or disloged, or you need a new developer.

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.

You have a toner detect problem.You will probably need to replace the TDC sensor in the developer unit.If you want you might be able to check the data control,mode 47-01&02.or 47-57 for the toner level power signal.
