6.10.9 TRAY LOCK MECHANISM
This machine has two types of tray lock mechanism.
Tray Lock at the Front
The lock at the front prevents the tray from coming out of the machine during transporting
or shipping. When you pull the handle [A], the lock lever [B] is lowered. As a result, you can
pull out the tray.

The pressure levers [A] put the proper pressu re to the nip between the pressure roller [B]
and fusing belt [C]. When releasing these levers , the pressure roller moves away from the
fusing belt. If a paper jam occurs in the fusi ng unit, releasing these levers make jammed
paper easily removed.
