2928 Toner End Recovery
Recovery starts after the toner cartridge is replaced when a toner-end condition
exists.
[0.130 to 0.215/0.145/0.005 V]
In the toner-end recovery process:
 The machine writes an ID sensor pattern on the surface of the drum.
 The ID sensor reads the density of the ID sensor pattern and converts it to an
electrical signal (Vsp).
 The machine compares the Vsp value with Vsg, which is read from the bare
surface of the drum (Vsg/Vsg=Vref)
 If Vsp/Vsg < Vref (the value of this SP setting), recovery is completed and the
machine goes back to normal operation.
2943 LED Duty Adjustment
Adjusts the on timing (the “width” or “duty”) of the LEDs in the LPH units to
change image exposure. Use this SP if it is necessary to make the output of one
LPH block brighter or darker. Raising the setting creates darker pixels, lowering
the setting creates lighter pixels.
1 LPH1
[1.0 to 20.0/12.0/0.1%]
The optimum LPH settings are printed on the label that is attached
to LPH replacement units. Always input these settings immediately
after the LPH unit has been replaced.
