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