Contents Details of function/operation
1 01 Mirror scan operation [Function]
When [ENTER]/[START] key is pressed, the home position is checked and the mirror base per-
forms full scan at the speed of the set magnification ratio.
During operation, the set magnification ratio is displayed.
The mirror home position sensor status is displayed with the "Copy mode lamp".
(When the mirror is in the home position, the lamp lights up.)
During operation, the copy lamp lights up.
When [Clear] key is pressed, if the operation is on the way, it is terminated and the machine
goes to the sub code entry standby mode.
[Operation]
02 Mirror home position sensor
(MHPS) status display
[Function]
Monitors the mirror home position sensor, and makes the "Copy mode lamp". Turn on during
the sensor ON status.
[Operation]
06 Aging of mirror scanning [Function]
When [ENTER]/[START] key is pressed, the mirror base performs full scan at the speed of the
set magnification ratio.
During operation, the set magnification ratio is displayed.
After 3sec, the mirror base performs full scan again.
[Operation]
The operation is similar to simulation 1-01.
2 01 RSPF aging operation [Function]
When [ENTER]/[START] key is pressed, the set magnification ratio is obtained. For the SPF, the
single-face document transport is performed. For the RSPF, the duplex document transport is
performed.
However, the operating conditions don't matter and the operation is not stopped even in case of
a jam. Also the magnification ratio is displayed on the LCD/display.
[Operation]
The operation is similar to simulation 1-01.
