2.2.5 Platen Gap (PG) Adjust Mechanism
The PG adjust mechanism, located at the top right of the printer mechanism, allows the user to set the
proper platen gap (distance between paper and nozzle surface) for the paper thickness to prevent ink
smudging. The PF Adjustment mechanism consists of the PG adjust lever, CR guide shaft, and
parallelism adjust bushings. Shifting the lever from “0” to “1” turns the CR guide shaft that joins to the
lever. The joint for the parallelism adjust bushing and CR guide shaft has an eccentricity toward the
guide shaft, which moves the guide shaft from or toward the platen. With this movement, the platen gap
changes from wide to narrow or vice versa.
