Description
The drum switch detects whether the drum is installed to the machine.
When it is detected that there is no drum installed, "NO DRUM" is displayed on the error LCD panel the
machine stops operation. When no drum is detected during operation, all the operations stops emergently.
Operation
When the drum is attached to the main body, the cam unit covers the pin and is locked firmly. The difference
of the cam unit prevents the cam unit from being loosened due to the machine vibration.
When the pin is at the bottom of the cam unit difference, the drum SW is on as shown in the figure. When the
pin is over the cam unit difference, the drum SW is off.
