To print, insert a time card into the receiver with the pay
period selected, facing you. Note: The clock cannot
differentiate the pay period and will print on either side
of the time card. The card is automatically pulled in and
printed. Do not attempt to pull the card out during the
printing operation or to insert any objects other than time
cards. Doing so can result in damage to printer.
VIII. Maintenance
Several simple suggestions may extend the life of your ATR120.
· Close the anti-dust cover after operation.
· When the case is dirty, wipe it with a damp soft cloth. If necessary, a mild
detergent may be used. Do not use any t ype of thinner or other chemical for
cleaning because the chemical could damage or discolor the case.

Replacing the ribbon

When the printing on the time card becomes light or hard to read it will be necessary
to replace the ribbon. Use the ATR122 replacement ribbon cassette (part number 39
0127 000). Attempting to “re-ink” the cassette will cause permanent damage to the
printer.
To open the front cover, turn the clock on its back and remove the two outer screws.
Stand the clock upright with the back facing you. With both thumbs press down on
IN1 and OUT3 buttons while using your fingers to push cover away.
