to this value during the TD sensor initial setting process]. This SP is effective
only when SP 2921 is “0”, “1”, or “2”.

ID Sensor Control
2927 1
[
0 = No
/ 1 = Yes]
Selects whether the ID sensor is or is not used for toner density control. This
value should normally be left at “1”. If the value is “0”, dirty background may
occur after long periods of non-use.
2928
Toner End Clear
2928 1
Clears the toner end condition without adding new toner. The following are
cleared:
ƒ Toner end indicator (goes out)·
ƒ Toner near-end counter
ƒ 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.
Vref Limits

Adjust the upper or lower Vref limit.

ID Sensor Detection Temperature [30 ~ 90 /
30
/ 1 C/step]
2994 1
While the machine is recovering from an energy saver mode, or while the
machine starts, the controller ignores the ID-sensor signals if the fusing
temperature is at the specified value or higher.
2996*
Transfer Roller Cleaning
2996 1
Selects whether the transfer roller is cleaned before each copy job. Set this to
“1” if dirty background is appearing on the reverse side of the first page of copy
jobs. Note that this will increase the time required to generate the first copy. If
the setting is “0”, the transfer roller is never cleaned ( p.249).
