Figure A-4. Remove the piece of cardboard packing that protects Hadix's pnnt

You'll be smart to save these screws, along with the rest of the

packing. (You did fill in that warranty card, didn't you?)
Installing the platen knob
This is the knob that turns the rubber platen cylinder. It fits
into the hole on the right side of the printer case. Just match the
odd-shaped hole in the knob with the same shape on the shaft
you'll see inside the hole in the case, and press it on firmly. Give
the knob a few turns to see that it's turning the platen easily and
smoothly.

The ribbon cartridge greatly simplifies installing the ink rib-
bon. For easy installation, though, it's wise to follow the sequence
and diagrams shown here.
