Description: LD unit home position error 2
The LD unit home position sensor does not detect an off condition when the LD unit moves from its home position.
Causes: • LD unit home position sensor defective • LD positioning motor defective • LD unit movement blocked because of incorrect connector routing
Code: SC329
Description: Laser beam pitch adjustment error
The LD unit home position sensor does not detect an on condition while changing the LD unit position for correcting the LD position or changing the dpi.
Causes: • The laser beam pitch adjustment (SP2-109-3 and 4) was not done after replacing the NVRAM or doing an NVRAM clear. • The laser beam pitch adjustment (SP2-109-1 ~ 4) was not done after replacing the LD unit. • LD unit movement blocked because of incorrect connector routing
Code: SC350-1
Description: ID sensor error 1
One of the following ID sensor output voltages was detected twice consecutively when checking the ID sensor pattern. 1) Vsp >= 2.5V 2) Vsg <= 2.5V 3) Vsp = 0V 4) Vsg = 0V
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at ID sensor pattern writing area of the drum
Code: SC350-2
Description: ID sensor error 2
The ID sensor output voltage is 5.0V and the PWM signal input to the ID sensor is 0 when checking the ID sensor pattern.
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum
Code: SC350-3
Description: ID sensor error 3
The ID sensor pattern edge voltage is detected to be not 2.5V twice consecutively during an 800 ms interval.
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum
Code: SC350-4
Description: ID sensor error 4
One of the following ID sensor output voltages is detected at ID sensor initialization. 1) Vsg < 4.0V when the maximum PWM input (255) is applied to the ID sensor. 2) Vsg >= 4.0V when the minimum PWM input (0) is applied to the ID sensor.
Causes: • ID sensor defective • ID sensor connector defective • Poor ID sensor connector connection • I/O board (IOB) defective • High voltage supply board defective • Dirty ID sensor • Defect at the ID sensor pattern writing area of the drum
