transfer
1. Transfer modes
The copier supports three transfer modes as de-
scribed below.
- Power-on mode
If the copier does not have the image control
program installed, its writing to the copier is
enabled when the main switch is turned on. Be-
cause the image control board controls the power
supply to the operation board, nothing will appear
on the operation LCD and timer LED will blink even
though the operation control program has been
installed on the copier.
- HELP + CHECK mode
Turning ON the copier with HELP and CHECK
puts it into the HELP + CHECK mode. If the copier
has the graphics control program installed, but
not the operation control program, the 25 mode
would not launch. This mode is specifically main-
tained to enable ISW in this situation.
