SP Modes
„
2001: Charge corona unit grid voltage
„
2201: Development bias voltage
„
2962: Manually executes a process control
z
Process control must be enabled with SP 3901 or it will not
work.
„
2966: Process control and corona wire cleaning interval
„
3001 002: Manually initializes the ID sensor
„
3103: ID sensor output display
„
3901: Auto process control enable/disable
„
3902: Process control data display
„
3903: Continued drum rotation after process control
„
3904: Controls what the machine does immediately after the
power is turned on
SP MODES
ˆ
2001 001: This is the value used during copying if process control is disabled with
SP3901)
ˆ
2001 002: This is the voltage used to make the ID sensor pattern
ˆ
2001 004: This is used during copying, but is changed next time process control is
done. Use this for testing the effects of a certain value.
ˆ
2001 005: This is the grid voltage used when copying to OHPs
¾
In OHP mode, process control values are not used. The SP values for OHP
mode are used.
ˆ
2201 001: This is the value used during copying if process control is disabled with
SP3901)
ˆ
2201 003: This is the voltage used when copying to OHPs (see 2001 005 above)
ˆ
2966: This is 24 hours by default. Adjust it if process control needs to be done
more often, especially if the wire keeps getting dirty (uneven density across the
page).
ˆ
3001 002: Forced ID sensor initialization (this is also done during auto process
control)
¾
This must be done after replacing certain parts, such as the NVRAM. If you
forget to do this, an SC code will appear (350 to 355 - not sure which one).
Then, to recover the machine, you must reset 3001 001 to the default.
ˆ
3903: Note the use of this SP if the image on copies is unfocused.
¾
3903 002 adjusts the length of time that the drum rotates.
