The paper-thickness LEVER, G, ADJUST allows the printer to use different weights of paper (different
thicknesses). The user controls this lever and alters the platen gap on the SHAFT, CR, GUIDE by changing
its position. Changing the position of the lever rotates the CHAFT, CR, GUIDE and moves the carriage
either toward or away from the PLATEN. Moving the paper-thickness LEVER, G, ADJUST to the fourth
position or higher slows down the printing speed to protect the
printhead. The PG sensor reads the
current position of the paper-thickness LEVER, G, ADJUST.
