1.3.3 ADF performance test (Function code 08)
<Function>
This function is used to test the performance of the automatic document feeder (ADF). The
scanned pages of the documents fed by the ADF are counted and the result is displayed on
the LCD.
<Operating procedure>
(1) Load documents on the ADF unit. “DOC.READY” is displayed on the LCD.
(2) Press the 0 and 8 keys in this order in the initial state of the maintenance mode.
The machine displays “ADF CHECK P.**” on the LCD and ejects documents while
counting the number of scanned pages. (** indicates the current count of scanned pages.)
(3) Press the X key to return the machine to the initial state of the maintenance mode.
Note:
For duplex scanning models, as 2 faces are scanned per a sheet of document, the
page count increases by two each time a sheet of document is ejected.
Note:
- If this test is performed as the ADF cover is opened, the machine displays “NO
DOCUMENT” on the LCD and returns to the initial state of the maintenance mode.
- If this test is performed as no documents are loaded in the ADF, the machine displays
“NO DOCUMENT” on the LCD and returns to the initial state of the maintenance
mode.
