Adjusts the development bias for making the
ID sensor pattern.
The actual development voltage for the ID
sensor pattern is this value plus the value of
SP2-201-1.

(ID sensor pattern)
This should not be used in the field,
because it affects ID sensor pattern density,
which affects toner supply. However, see
‘Troubleshooting – Toner Density’ for one
occasion when this SP mode can be used,
Section 7.4.

Selects the number of copies that can be
made after toner near-end has been
detected.
2-213*
Copies after Near
End
If the user normally makes copies with a
high proportion of black, reduce the interval.

Displays the Vt, Vsg, Vsp, and Vsdp values.

Vt/Vsg/Vsp/Vsdp
Data Display
The Vt values are displayed as follows:
e.g. Vt2.14/2.29
The left value is the actual TD sensor
output. The right value is the target Vref
value.
0: No
1: Yes
Displays the Vsg, Vsp, Power, Vsg-Vsp, and
Vt values for ID sensor error conditions. See
“ID Sensor Error Analysis” later in this
section 4.2.17 for more detail.
2-221*
ID Sensor Error
Display
There is no SC code for the ID sensor error
in this machine. Check the ID sensor values
with this SP if abnormal copies are made
(such as dirty background) to determine
whether the problem is due to incorrect
toner density control.
Adjusts the current applied to the transfer
roller during copying from a paper tray when
the user uses the “
Normal
” paper setting.

If the user normally feeds thicker paper from
a paper tray, use a higher setting.

Adjusts the current applied to the transfer

These settings are also used if the 2

tray is
used and special paper is selected with the
switch in the tray.

Transfer Current
(By-pass Feed)
If the user normally feeds thicker paper from
the by-pass tray/2
nd
tray (special paper), use
a higher setting. If waste toner is re-
attracted from the drum (this can occur
when using an OHP sheet), use a higher
setting.
