[7] OPERATIONAL DESCRIPTIONS (Document) 1. Optical system 1-1. Optical system outline Light source: Fuse bulbs are used as the light source. Eight fuse bulbs are arranged in series on the PWB. The temperature fuse is also installed on the PWB. The copy lamp also has the function as the discharge lamp to attenuate the potential on the drum.
2-2. Outline of paper feed operation <<Z-26>> When the COPY key is pressed, the motor starts rotating. At the same time, the paper feed solenoid turns on to raise the stopper. Paper is fed and the paper entry sensor (PID) is turned on. The paper is stopped by the resist roller.
4-2. Outline of operation 5. Others Positions of the racks, the bracket guide, and the C bracket are shown below: 5-1. Fusing temperature control Rack guide When the power is turned on, the power relay is also turned on at Bracket guide position the same time.
5-2. Toner empty control When the paper entry sensor (Z-21) or the COPY key (Z-26) is turned on, if the toner control sensor output (TCS) is HIGH, the toner supply solenoid (THS) is turned on to supply toner. If TCS is not driven LOW after 60 sec of toner supply, the developer cartridge replacement lamp is lighted and the machine is stopped.
