1. Attach the molded male end of the printer cable to the connector on the left rear
of the CGP-220. Do not force the plug. If it doesn't fit, turn it over and try again.
2. Connect the other end of the cable to the Printer Jack of your Computer. See
your TRS-80's owner's manual for specific instructions.
3. If you're using the Serial Interface connection, set the Baud Rate Switch to the
appropriate position.
Important Note! You may use either the Serial or Parallel Interface connectors, but
never both at the same time.
Power-Up Sequence
The precise power-up sequence will depend upon your Computer. We suggest that
you consult your owner's manual for details on powering up your TRS-80 with
peripheral devices (such as printers).
Replacing the Ink Packs
Your CGP-220 comes with two Ink Packs installed. The Black Ink Pack (26-1281)
can print about four million characters; the Tri-Color Ink Pack (26-1282), about three
million.

When printing quality does not improve after repeated Ink-Supply Pumping and you
have already printed more than eight rolls of paper, it is likely that the Ink Packs are
exhausted.
To replace the Ink Packs:
1. Turn the power OFF.
2. Insert a coin or a small flat object in the opening of the Ink Pack Compartment
and, carefully, pry it open.
3. Grasp the empty Ink Pack by the sides and pull it out gently but firmly.
4. Be certain that the Ink Pack is empty by holding it sideways and then shaking it. If
the ink sack inside does not jiggle freely, the Ink Pack is empty.
5. Insert the new Ink Pack in place, making sure it stays firmly attached.
6. Pump the Ink Supply.
7. Close the Ink Pack Compartment.
Note: Dispose of used Ink Pack immediately; remaining Ink may spill.
