Media Frame Replacement 980357-207A

Preparations

Protect against static discharge. Your work area must be static-safe and include

a properly grounded conductive cushioned mat to hold the printer and a

conductive wrist strap for yourself.

Open the cover, and remove any media and ribbon (if necessary).

Removal

1. Use a #1 Phillips driver to loosen the four

screws 1 that hold the frame 2 to the

bottom case

2. Lift the frame 2 free of the print mechanism

and bottom case.

Optionally, you can detach the feed switch ribbon

cable 3 from its connector on the main PCBA

Assembly

If necessary, plug the feed switch ribbon cable into

its connector on the main PCBA.

1. Align the frame so that the feed button/LED

are to the left; then, lower the frame onto the

bottom case and behind the print

mechanism.

2. Replace the four screws that hold the frame to the bottom case and use a #1 Phillips driver to

tighten them.

Assemble the Printer

Reload media and ribbon, if necessary.

Check the installation. Plug in the power cord, turn on the printer and run the AutoSense routine to

get a dump mode printout. This action tests the printer's media drive and printing capabilities.
