It is detected whether the protection material has been removed from the new cartridge.
At the time of shipment, a toner cartridge with a protection material (sealing tape) has been inserted into the machine. This protection material needs to be removed
when the machine is installed.
When the power is turned ON without removing the protection material, the new cartridge sensor flag is pressed by the protection material, so a new cartridge sensor
(SR716) detects the presence of the protection material. In this condition, the machine determines that the protection material is not removed from the toner car-
tridge, stops the operation, and then displays a message prompting an operator to remove the protection material.
