5.1 Head Gap
1.
Set the head gap lever to the single sheet
position.
Set the paper feed selector to the "EY" position.
Ensure the printhead is firmly secured with 2
screws.
Move the carriage to the print start position on
the platen, and adjust the head gap between the
platen and the printhead for a clearance of
0.35mm-0.40mm
by turning the left eccentric
cam.
Move the carriage to the print end position on the
platen, and adjust the gap as per step 4 above by
turning the right eccentric cam.
Note: The projection
on the eccentric cam
is
released from the adjustment hole by pulling
the knob. Turning the eccentric cam one step
causes 0.037mm-0.052mm head movement.
Note: Use only a round wire feeler gauge of the
specified dimension for this adjustment.
Note: The head gap adjustment is required when
replacing the head, platen, carriage, carriage
shaft and eccentric cams.
Note: Moving the head gap lever towards the @
position increases the head gap clearance,
and moving toward the @ position decreases
the clearance.
