Polygon Mirror Rotation Switch DFU
2981
Switches the number revolutions per minute of the polygon mirror motor.
0: Rpm determined by engine
1: Rpm for 35 CPM (35 cpm)
2: Rpm for 45 CPM (45 cpm)
SP3-xxx: Process
3001 ID Sens Initial ID Sensor Initial Setting
ID Sens PWM Set ID Sensor PWM Setting
001
[0 ~ 255 / 100 / 1 step]
Allows you to reset the PWM of the ID sensor LED to avoid a service call error
after clearing NVRAM or replacing the NVRAM.
The PWM data is stored by executing SP-3001-2.
Initial Setting ID Sensor Initialization
002
Performs the ID sensor initial setting. ID sensor output for the bare drum (VSG) is
adjusted automatically to 4.0 ±0.2 V.
Press “Execute” to start. Perform this setting after replacing or cleaning the ID
sensor, replacing the drum, or clearing NVRAM.
ID Sens Out Disp ID Sensor Output Display
3103
Presents on the display the current values of Vsg, Vsp, Vpdp, and grayscale
control.
If the ID sensor does not detect the ID pattern, “VSP = 5.0 V/VSG = 5.0 V” is
displayed and an SC code is generated.
If the ID sensor does not detect the bare area of the drum, “VSP = 0.0 V/VSG
=0.0 V” is displayed and an SC code is generated.
001 Vsg Drum Surface Output
[0V ~ 5.00V]
Vsg is the ID sensor output after reading the bare drum surface.
Normal display: 4±0.5 V
