1. Remove the old Platen Assembly
Carefully lift up the end of the platen with the gear as shown at “2” in the illustra-
tion above until it snaps free from the media cover.
Slide the other end of the platen out of the Media Cover.
2. Install the New Platen Assembly
Units using linered media use the Platen Assembly included with Platen and
Roller Kit p/n AN16753-021. Linerless units will take the Platen Assembly includ-
ed with Platen and Roller Kit p/n AN16753-022.
Install the new Platen Assembly in the reverse order you removed it. Insert the
shaft end of the platen into the media cover, then rotate the end with the gear
until it snaps into place. Ensure that the new Platen Assembly spins freely.

Remove the old Peeler Bar or Scraper and replace with a new Peeler Bar (sup-
plied with Kit AN16753-021) or Scraper (supplied with Kit AN16753-022). Refer to
“3” above These components can be changed without removing the Platen As-
sembly. Note that the Peer Bar must be installed on units using linered median

replace the Media Rollers (shown at “4”) with a compatible type. Refer to the QL
