Tray Present Switch - When the 250 sheet paper tray is inserted to the specified position,
the end of the tray presses the tray present switch, and the printer recognizes the tray is
inserted.
Tray 1 Empty Flag - When sheets of paper in the 250 sheet paper tray are used up, the
end of the tray 1 empty flag drops in the opening of the lift plate, and the flag shades the
tray empty sensor.
Tray 1 Empty Sensor - Senses whether paper is set in the 250 sheet paper tray at the
position of the tray 1 empty flag, and converts the sensing result into an electric signal.
When the sensor receives the light, the NO PAPER1 signal (paper setting state) is set
low.

drops in the opening in the center of the MPF tray, and the flag shades the sensor.
MPF Empty Sensor - Senses whether paper is set in the MPF tray at the position of the
MPF actuator, and converts the sensing result into an electric signal. When the sensor
receives the light, the NO PAPER MPF signal (paper setting state) is set low.

multiple sheets from being picked simultaneously. This component is to be replaced each
time 100,000 sheets are printed.
Tray 1 Pick Roll - Supplies paper from the 250-paper tray to the printer. The rotation is

turns once to supply paper. The pick roll is to be replaced each time 100,000 sheets are
printed.
