I have a Konica Minolta 4690MF and have black toner all of my paper when printing.

SOURCE: Konica Minolta 2400W Error Message

remove the opc drum.

there are two black plastic flags that detect paper jams. one is high up just below the fuser unit. The other is roughly half way up the printer between two small transfer rollers very close to the opto sensor. Apparently it frequetly gets jammed behind the plastic cover, and once jammed you would never realise it is there.

I managed to prise it out from behind the cover and the "paper jam at transfer roller" message was cleared.

Unless you know it is there and hiding it is not obvious at all that anything is wrong.

SOURCE: Toner Not Installed - After replace black

This is actually a desigbn fault on the magicolor printers. Underneath the toner rack is the 3 pin chip reader - normally white and plastic with 3 metal contacts sticking out.

it is at the bottom of the printer so very often toner drops onto it and the sensors dont work, it also takes a bit of a beating as the cartridges rotate. Its very easy to replace - but you need the part,

Minolta should have put it at the top rather than the bottow where it gets covered in dust.

these guys helped me a lot

You can change the 2300's menu setting to ignore empty toner cartridges and keep printing. There are 2 steps:

Step 1:

Press Menu/Select, then "right arrow" until you see ENGINE. Press Menu/Select again and then "right arrow" until you see TONER EMPTY. Press Menu/Select and you'll see STOP. Press "right arrow" once to change to CONTINUE. Press Menu/Select.

Step 2:

Press "right arrow" until you see AUTO CONTINUE. If set to ON, press the "Cancel" button and you're ready to print. If set to OFF, press Menu/Select, then right arrow to change to ON, then Menu/Select to enter. It will say "ON IS SELECTED." Then press the "Cancel" button and you're ready to print.
