Is that true for both print and copy job ?
Where does the jam happen ?
I am thinking if it is at the paper pickup roller area just as the job starts to print and not midway while printing, check the paper quality; dirty pickup roller; clean cork pad and try job from another tray
SOME attempted COUNTERFITTING There is nothing that can be done, Get a tech out who will remove a chip the chip will be sent to Konica Minolta and then to the US SECERT SERVICE for determining what was done. until then machine will remain inop!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Make sure you remove the zeal/lock the knob if you already did that, Open and closed the main door while the machine is On. Wait for 2 mins to machine to adjust for the New toner.
