[Step 1] Remove the printer mechanism. (Refer to section 3.2.4.)
[Step 2] Move the carriage to the middle of the printer.
The carriage is located between first and

unit.
■
Never touch the nozzle surface and a metallic cover of the
printhead.
Handle it by only
holding the edges of the
printhead.
■
When
the
~“nthead or the printer mechanism is replaced,
the
block
resistor must
be
replaced at location RM22 on the C106 MAIN BOARD.
(Every
spare
printhead
or spare
printer mechanism is come with a block resistor that specifically selected to each
printhead,
to ensure optimal control of the driver circuit.
