printhead is at the
80-column printer or at the 130th column print position for a 136-column printer.
Use the box driver (7 mm) to rotate the adjusting bushing on the right frame of the printer mechanism.
Rotate the adjusting bushing until the platen gap is large enough for a 0.36 mm thickness gauge
but too narrow for a 0.40 mm thickness gauge.
Move the
printhead back again so that the edge of the printhead is at the 5th column print position.
Check the platen gap again with the thickness gauge. It should still be large enough for a 0.36 mm
thickness gauge but too narrow for a 0.40 mm thickness gauge. If this is not the case, go back
to step 8.
Center the carriage. Check the platen gap again with the thickness gauge. It should still be large
enough for a 0.36 mm thickness gauge but too narrow for a 0.40 mm thickness gauge. If this is
not the
case,go back to Step 8.
Remove the
printhead,
install the ribbon mask, and then replace the printhead.
