Drum surface potential 54
Drum surface potential the laser beam is continually switched on and off depending on the print data it is on for a black exposed dot and off for a white blank dot since the drum surface is evenly charged whenever it is illuminated by the laser beam the electrical resistance of the photoconductor is reduced and the potential on the photoconductor is also lowered resulted on the drum surface is an electrostatic image which represents the data to print note that the area to be printed black has the low potential constituting a positively exposed image 54

Eraser lamp control circuit 66
Eraser lamp control circuit the cpu turns pin 45 erasern of u01 to h level transistors q12 and q13 turns on consequently and the 24 v dc given at pin 1 of yc05 applies to the eraser lamps the eraser lamps thus illuminate as the current flows through the eraser lamp the 2nd pin of yc05 resistors r58 r59 and r61 and the ground pin 27 errdyn of the cpu u01 is wired to the crossing of r59 and r61 via r60 the cpu turns pin 45 erasern to h level and monitors the input level after one second if the eraser lamp is normal the current flowing through r60 also flows dz02 making the voltage at pin 27 to be approximately 2 v on the contrary if the level at pin 27 errdyn is less than 1 v for more than 2 seconds despite the cpu turns pin 45 erasern to h level and applying the 24 v dc to pin 1 of yc05 the cpu recognizes that the current is not flowing through the eraser lamp the message call service person e5 is then displayed 66

Heater lamp control circuit 67
Heater lamp control circuit the heater lamp control circuit turns the heater lamp on and off which is located coaxial inside the heat roller so that the surface of the roller maintains the constant specific temperature needed to permanently fuse the toner on paper the heater lamp is directly fed with ac primary power 120 v or 220 240 v which is supplied from the power supply board the cpu u01 detects variation in voltage resultant of change in temperature given at pin 33 therma by the thermistor this voltage is used to effectively switch the fuser lamp on and off if pin 1 heat is h level transistor array qa01 pin 5 turns on the photo coupler on the power supply board turns on and the triac turns on consequently the heater lamp is ac powered and lights the heater lamp continuously turns on and off to maintain the temperature on the heater roller at approximately 170 c normal paper and 185 c thick paper for printing and approximately 160 c at stand by 67

If the temperature does not decrease more than 1 c within 20 seconds since the cpu turns pin 1 heat off to disable the heater lamp the printer displays call service person e4 67

Polygon motor control circuit the main controller board supplies the 1417 hz clock pulse plgclk via the engine board to the pll control ic ic1 for the polygon motor to begin printing the engine cpu u01 turns plgdr to h level the pll control ic ic1 starts to revolve the polygon motor so that the revolution is 14 173 rpm which depends on the plgclk clock pulse when pll control ic ic1 finds that the polygon motor is revolving at the rated speed turns plgdrn to l level to acknowledge the engine cpu that the rated speed has been achieved on the contrary if plgrdyn does not turn to l level within 8 seconds since plgdrn has been l level the printer displays call service person e2 69
