2.2.3 Head Gap Adjusting (See Figure 2-5.)
The head gap adjusting lever moves back and forth to tilt the carriage frame, altering the gap
between the printhead and the platen.
The adjusting screw, which is connected to the adjusting gear rotates when the adjusting lever
is moved creating a fine gap adjustment. If the adjusting gear is pushed down, the adjusting
screw can be turned with a screw driver to change the coarse gap adjustment.
When the adjusting lever is set to range ➁ ~ ➄, the contact attached to the under side of the
carriage cover will connect with the contact of the space motor PC board. The printer will reduce
the printing speed automatically to ensure that adequate printing pressure is maintained for
multipart paper.
Moving the adjusting cam toward the left or right adjusts the guide rail up or down.
