Platen Gap Adjustment - Epson FX-2170 Service Manual

FX-2170 Service Manual

2.1.3 Platen Gap 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
position is 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
between the platen gap and the print speed.
