14. Replacing Ribbon Cartridge
1. Open the top cover and press button [PM Out 2]. The print head
will move to Column 4 to make it easier to remove the ribbon cartridge.
Tip: if column shifts are programmed the print head could move after 3 sec. and could pinch
your fingers. To avoid this move the print head to Col. 4 and slide the programming switch to
“Prgm”. This will prevent the print head from moving. When you are finished changing the ribbon
slide the programming switch back to “Run”.
2. As shown in the figures below, pull the ribbon holders towards you to unlatch the ribbon cartridge. Use
the handle on top of the ribbon cartridge to pull it up and out of the clock.
3. Blow any paper dust off the print head and from the inside of the clock using a can of compressed air.
This could help prevent ribbon or card jams. Carefully insert a new cartridge, positioning the ribbon
between the plastic ribbon guide and the stainless steel print shield. Push the cartridge down until it
clicks into place. Turn the ribbon knob clockwise to remove any slack in the ribbon. Slide the program
switch back to “Run”.
15. Cleaning the ATR120
Do not use cleaning products that contain alcohol or other strong chemicals as they could discolor or crack
the terminal housing. Use a soft damp cloth to remove dirt. Wipe dry. Use compressed air to blow paper
dust off the print head and the inside of the clock. This should be done with at least every ribbon change.
Cans of compressed air or “Dusters” can be found at any office supply or superstores.
