Sp3-Xxx: Process - Ricoh A-P4 Service Manual

When SP2975 is set to any value other than "0", this value is displayed when it matches the
setting of SP2975. When SP2975 is set to "0", SP2976 is disabled. SP2976 is automatically
set to zero by toner end recovery.)
Charge Counter
[0 ~ 1000000 / 0 / 1 step]
Sets the number of pages to print after toner and carrier initialization before the charge input is
2980
increased to compensate for deterioration over time in the polarity of the carrier.
The strength in the polarity of the carrier in the toner will eventually decrease and cause lower
charge output. Setting the charge output to increase after a specified number of copies can
compensate for this effect.
Polygon Mirror Rotation Switch DFU
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)

3001 ID Sens Initial
ID Sens PWM Set
[0 ~ 255 / 100 / 1 step]
001
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
Performs the ID sensor initial setting. ID sensor output for the bare drum (VSG) is adjusted au-
002
tomatically 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.
