Description
e top cover and the print frame are connected by the top cover locks and
can be tilted up from the base frame as a single unit. e top and bottom
parts of the printer are held together by the base locks, one at each side of
the base frame. e base locks engage the base lock spring hooks fitted at the

printout and to drive the media.
e base locks are each provided with a microswitch that is activated by the
base lock spring hook in order to detct whether the print frame is in locked

-
switches are activated.

connected to JP11 on the main board.
