/1 (M25) is detected.
An error detection signal of M25 is
detected while M25 is ON.
(PS6) is OFF, PS6 does not turn
ON within 20 seconds after the
paper lift motor /1 (M25) turns ON
for lifting operation. And at this
time, an error detection signal
(24V cut off) is detected.

operation
The main body Paper lift motor /1 (M25)
stops immediately Upper limit sensor /1 (PS6)
to turn OFF the

the lifting opera-
Printer control board (PRCB)
tion of the tray is
not completed,
"Set paper in the
tray 1" is displayed
on the operation
board.
