Maintenance: Inspection and Cleaning
Perform a visual inspection of all equipment and peripheral devices daily. Turn off
the unit and remove power before making an inspection or cleaning the unit.
Check the case and display screen for cracks or other damage.
Regularly inspect all cords and cables for fraying or other damage.
Verify that all cords and connectors are securely seated.
Inspect keys and controls for proper operation and check that toggle keys do not
stick in one position. If necessary, perform the keyboard test described in the
Chapter 5 of this manual.
Clean the exterior surfaces monthly, or more frequently if needed.
1.
Use a clean, soft cloth and a mild dish washing detergent diluted in water.
2.
Wring the excess water from the cloth. Do not drip water or any liquid on the
equipment, and avoid contact with open vents, plugs, or connectors.
3.
Dry the surfaces with a clean cloth or paper towel.
Check for dust buildup on the surfaces of the interior circuit boards, components,
and power supply. Use commercially available compressed air to blow away the
accumulated dust. Follow the manufacturers directions.
Clean the thermal printhead every three months or more often with heavy use. A
build-up of thermal paper coating on the printhead can cause light or uneven
printing.
Use a solution containing alcohol on a nonwoven, nonabrasive cloth such as Techni-
Cloth to wipe off the printhead. Do not use paper toweling, as it can scratch the
printhead.
