Platen Guide
Platen type of a printer may be determined by taking a look at the DPI & Width#
area of the printer’s serial number tag. In the above example you see the
letter “U” at the end of the Width# ID. This indicates the printer has a UPG paper
guide. The platen currently in the printer may look different than the below replacement
platen photos.
