5.7 Base Locks

Description
Intermec EasyCoder PC4—Service Manual
The 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. The top and bottom
parts of the printer are held together by the base locks, one at each side of
the base frame. The base locks engage the base lock spring hooks fitted at the
print frame (see Chapter 4.4).
Note: Parts are marked with "L" or "R" indicating left or right side.
When the print frame is closed, the V-spring ensures that the printhead
is pressed against the platen roller with a sufficient force to provide a clear
printout and to drive the media.
The 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
position or not. Closed and locked position is assumed when both micro-
switches are activated.
The right-side base lock is connected to JP12 and the left-side base lock is
connected to JP11 on the main board.
