DOC-REC

Level 3
DA-XS Fine-Adjusting the Original Detection Area
DA-XE If an original is placed on the copyboard glass at an
DA-YS angle, its copy will be framed in black by the work
DA-YE of original detection mode. Use this item to make
(Note 1) settings so as to remove such frames.
Keep in mind that a change in the settings will affect
the frame width in original detection mode while the
projector is in use.
DS-DOC Adjusting the Slice Level for Original Detection
(Note 1) You may set a slice level of your choice for original
detection.
A higher slice level will increase the degree of
detection of an original, but at the same time will
lead to wrong detection.
Note 1: Execute this mode upon replacement of a CPU PCB or initialization of the RAM. The settings
will be returned to standard settings, requiring you to enter the appropriate settings. Be sure to
record any new settings on the service label.
