Enter dC330 [008-040 T
ray 5 Lifter Motor CCW]. Press Start and Stop several times.
CAUTION
Do not operate the component control more than twice before resetting paper position. To
lower the paper f
rom the feed position, pull out respective tray. If the tray is overdriven, it will be
hard to pull out and may cause component damage.
The Feed/Lift Motor energizes and deenergizes.
