Check Method
<WARNING> <CAUTION>
Conduct 2ND BTR output
with Digital Output Test
[54] and [A0] and Analog
Output Test [01], and
check the data with this
diagnostic.
Check by this DIAG while
executing Digital Output
Test with the code [72].
Switch ON/OFF the four
Cassette 1 SIZE SWITCH
ASSY paper size switches
and check the data with
this diagnostic.

Check Method
Check data.
[Note : When
DigitalOutputTest [46] is
executed, it becomes the
sermister breakage
detection mode, and
becomes the [00EAh]
above in the case of the
breakage.]
Check data.
-
Measure the error of the
5VDC power supply, and
correct data on the code
[02].
It usually becomes 00C9-
00DE (3.23V-3.57V).
Check data.
<WARNING> <CAUTION>
Conduct 1ST BTR output
with Digital Output Test
[54] and Analog Output
Test [00], and check the
data with this diagnostic.
