19) Motor aging
•
Whether a document is present or not, the motor in the sending
system is kept in rotation until the STOP key is pressed.
•
The image quality selection key can be input during stop alone to
set the rotation speed for the image quality.
(Here, the speed for FINE is selected when the intermediate tone
is specified.)
•
The image quality for default at the start of execution is STD
regardless of the image quality selection priority of the main body.
•
For rotation, the key "1" selects the 1-2 phase excitation, "2"
selects the 2-phase excitation and "3" selects the micro step. It can
not be changed during rotation. The 1-2 phase excitation is set as
default.
20) Stamp aging
•
It is impossible if any document is not set up.
•
The document is fed at the 10 mm intervals, and is continuously
stamped.
•
The total number of stamps from entry of the mode is displayed on
the screen.
•
The ordinary operation aging which stamps a finish every docu-
ment is executed in the ordinary copying mode.
21) Scanner set mode
•
The reading width and motor drive conditions are set.
<Reading width>
1. Top margin
2. Bottom margin
3. Left adjustment (The left position alone is specified.)
Specify the above values.
•
Select the above items 1, 2 and 3 with the [
set the values with the [←] and [→] keys. The values can be set in
the range of +3.0 mm to -3.0 mm at the 0.1 mm intervals. While
the [←] and [→] key is continuously pressed one second or more,
the setting value is automatically increased/decreased (in the
range between the upper and lower limits).
•
Input the quality selection key, and the value will be respectively
set corresponding to the selected image quality. Here, the interme-
diate tone is the same as for the setting value of FINE.
±0.0 mm is default for all.
•

5. Phase
6. Slow-up

6. 3 steps
7. 3 steps
•
Input the quality selection key, and the value will be respectively
set corresponding to the selected image quality. Here, the interme-
diate tone is the same as for the setting value of FINE.

22) Dial test mode
The mode is used to inspect whether dialing is accurate in two kinds
of dial modes
automatically called up in both PB mode and DP mode.
When this mode is activated, the following operations will be automat-
ically executed
with the external instrument which is connected to the line cable.
This mode uses the ordinary auto dial. (Accordingly, the signal send-
ing time and minimum pause are all the same as ordinary.
The measurement result in this mode is completely all the same as in
the ordinary dial mode.
Moreover, the same process as above is also done in the dial test
mode which is executed in the product check mode.
23) Copy diag mode
In order to shorten the process time during production, this mode is
used to automatically switch the copy mode. Three menus are pro-
vided.

When copy test is tried during production or is checked in two modes
(fine and intermediate tones), this mode is provided to reduce the
troublesome work which makes the operator stand aside to change
the mode. Accordingly, the fine and intermediate tones are merely
switched, and the mode is not switched to another mode. (Input of the
image quality/density key is invalid.)
