[0 = No / 1 = Yes]
Selects whether the ID sensor is or is not used for toner density control. This
2927 1
value should normally be left at "1". If the value is "0", dirty background may
occur after long periods of non-use.
Toner End Clear
2928
Clears the toner end condition without adding new toner. The following are
cleared:
Toner end indicator (goes out)·
Toner near-end counter
2928 1 Toner near-end level
This function should generally not be used. If you clear the toner end condition
without adding new toner, there is a risk that the drum may eventually begin to
attract carrier after many more copies are made and toner runs out. This
attracted carrier may damage the drum.
