2.2.6.1 Top cover open/close detection mechanism
When the top cover is opened, two switches open causing the SP motor
and printing to stop. The Cover Open Switch assembly (CO SW ASY)
and the Interlock Switch assembly (INLK SW ASY) are installed on the
right side frame. When the top cover is closed, the two switches are
closed and printing resumes.

The Interlock and Cover Open switches can be bypassed as
explained in the table below if the unit is needs to be
operated with the top cover or upper housing removed.

Exercise extreme care when working on the unit with these
safety switches bypassed. The SP motor is enabled, and the
Carrier unit moves at very fast speed. If the Carrier unit
strikes you at high speed, it could result in injury.
