2.1.3 PlatenGap Adjustment
You can adjust the platen gap (the gap between the platen and printhead) to allow the printer to use paper of
different weights or thicknesses. When you move the platen gap adjust lever forward or backward, the
carriage guide shaft rotates. This rotation moves the carriage either toward or away from the platen and
changes the platen gap. This adjustment function has nine ranges for the adjustment, and the adjustment
positionis detected by 2 platen gap(PG) switches.
Moving the platen gap adjust lever beyond position 4 changes the print speed mode to Copy 2 mode, and the
speed slows down to about 2⁄3normal to protect the printhead. The following table show you the relationship
between theplaten gap andthe print speed.
