2. Cassette Feed
2-1. Feeder Assembly
(1) If an optional feeder unit has been installed, remove
it before proceeding to the next step.
(2) Remove the cassette.
(3) Lay the printer on its rear cover.
(4) Remove the four screws
[1]
.
(5) With the unit still in its upright position, separate the
feeder assembly
[2] from the main unit (base en-
gine). The feeder assembly
[2]
and main unit (base
engine) are connected by the harness assembly out
[3] , so be careful not to separate the feeder assembly
[2] by too great a distance.
(6) Remove the connector (P/J 115) on the feeder PCB,
and take off the feeder assembly
[2]
.
When the feeder assembly [2] has been removed,
there is still a chance that the surface where the
assembly was attached can be scratched by the tip of
the screw, so leave the base engine in its upright
position. Be very careful, when carrying out this
operation, not to knock over the base engine.
Caution when assembling:
When setting the base engine on the feeder assembly
[2] ,
line up the base engine carefully, being careful of the
positioning boss on the top surface of the feeder assembly
[2]
, and be careful not to let the harness get caught between
the two units.
