Fuser AC Power Control
Fuser (e-coil) gets heat from AC power. The AV power controls the switch with the Triac, a sem-
iconductor switch. The ON/OFF control is operated when the gate of the Triac is turned on/off by
Phototriac (insulting part). In other words, the AC control part is passive circuit, so it turns the heat-
er on/off with taking signal from engine control part. When the HEATER ON signal is turned on at
engine, the LED of PC501 (Photo Triac) takes the voltage and flashes.From the flashing light, the
Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of Triac
and flows into the Triac. As a result, the AC current flows in the e-coil, and heat is occurred. On
the other hand, when the signal is off, the PC501 is off, the voltage is cut off at the gate of Triac,
the Triac becomes off, and then the e-coil is turned off.
• Triac (Q501) feature: 24A-LV model / 16A-HV model, 600V SWITCHING
• Phototriac Coupler (PC501)
-Turn On If Current: 15mA ~ 50mA(Design: 16mA)
-High Repetitive Peak Off State Voltage: Min 600V

Control Algorithm
• Feeding
If feeding from a cassette, the drive of the pickup roller is controlled by controlling the sole-
noid. The on/off of the solenoid is controlled by controlling the general output port or the
external output port. While paper moves, occurrence of Jam is judged as below.
