Question about Minolta Office Equipment & Supplies
This service code C0070 is a universal code used by Konica Minolta to indicate a toner bottle rotation failure. These machines add toner by rotating the toner bottle that you install in the machine. Most of the time this code is caused by a toner cartridge that has been installed incorrectly or has become dislodged from it's holder. To clear the code open the front door or toner door and remove the toner cartridge/bottle from the machine. Close the toner door and turn the machine off then on to reset the code. Let the machine run. This may take several minutes and will allow the machine to bring the toner bottle receptacle into it's home position. Once the machine stops running completely, then you can re-install the toner cartridge. If the code does not come back you are ready to go. If the code came back after removing the toner but before you re-installed it then you have either a dirty rotation sensor or a bad toner drive motor and will need service.
If the code comes back after the cartridge is re-installed then there is either a priblem with the cartridge or with the toner bottle drive.
Most of the time though the problem will be resolved by the outlined procedure.
Good Luck and Thank You for using Fixya.

Tips for a great answer:
If the machine is throwing the C0070 code without the bottle being inserted than likely the worm gear of the little drive motor of the toner bottle holder is damaged.
If C0070 is only coming up with the bottle inserted, than the bottle may be wrong or damaged from previous attempts.
To reach the toner bottle holder ("hopper") mechanism you have to remove the rear cover.
