Ricoh Neptune-P1 Service Manual page 398

SP3103 (ID Sensor Output Display) shows the most recent values of Vsg and Vsp that were stored in the
NVRAM (Range: 0.00 ∼ 5.00 V).
Supply Modes
There are two supply modes.
• Detect Supply Mode
• Fixed Supply Mode
During normal operation, the machine uses detect supply mode.
Detect supply mode has two sub-modes (referred to as "tables").
• Main table: Used during copying
• Length table: The machine switches to this table during copying if the length of the copy becomes
more than 1189 mm (46.8").
If an ID sensor problem occurs during the job, the machine stops the end of the job. The machine does not
go into fixed supply mode automatically. The technician must repair the machine. If the machine cannot
be repaired, the technician must put the machine into fixed supply mode with SP2208-3.
In fixed supply mode, the machine supplies a set quantity of toner per page.
After the technician repairs the machine, the machine must be put back in detect supply mode with
SP2208-3.
Detect Supply Mode
- Main Table -
The machine uses this table from the start of the page until the length of the printed page gets to 1189 mm
(46.8").
The machine uses these two parameters to control the rate of toner supply:
• Vsg/Vsp
• The toner supply level set with SP2208-1
