Operation/Procedure
1) Set the tray document guide to the max. width position, and
press [EXECUTE] key. The button is highlighted and the tray
size volume maximum value adjustment is started.
* During the adjustment, EXECUTING... is displayed.
* After completion of the tray size volume maximum value
adjustment, the set value is saved to EEPROM and RAM
and the display is shifted to the tray volume A4R size adjust-
ment value start screen. (Each set value is saved to
EEPROM and RAM at each setting.)
2) Set the tray document guide to A4R (11 x 8.5R) width position
and press [EXECUTE] button. The pressed button is high-
lighted and the tray A4R size adjustment is started.
3) Adjust the tray volume A5R size and the tray size volume min-
imum value according to the above procedures.
4) After completion of the adjustment, COMPLETEis displayed.
If the adjustment is not completed normally for any rea-
son,ERRORis displayed. In that case, the adjustment must
be executed again.

When one of 1-4 in the above table is selected, the guide plate is
shifted to each position of the four widths of the guide plate shown
in the table below. The value of the document width sensor
(RSPF_WIDTH) A/D value is saved to EEPROM.

Item: Adjustment
Operation/Procedure
1) Select the set item with [↑] and [↓] buttons.
The highlighted section of the set value is switched and dis-
played on the set setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* When [C] key is pressed, the entered value is cleared.
3) When [EXECUTE] button is pressed, it is highlighted and print-
ing is started.
* After completion of printing, [EXECUTE] button returns to
the normal display.
* When [OK], [↑], [↓] button, [COLOR], or [BLACK] key is
pressed, the value is set to the set item. (The value is not
saved to EEPROM and RAM.)
* When [C], [CA], [SYSTEM SETTINGS], or [EXECUTE] key
is pressed during printing, the operation is interrupted.
* When the machine returns to the ready state after occur-
rence of an interruption, printing is resumed.

* Item B is displayed as Display item: Detail of display.
