To maintain Zebra devices, avoid harmful chemicals such as acetone, ammonia solutions, benzene, bleach, and trichloroethylene, as they damage plastics. Use approved cleaning agents such as pre-moistened wipes and 70% isopropyl alcohol. Use a dampened soft cloth for routine cleaning to avoid liquid pooling and direct spraying into the scanner exit window. Clean the window with lens tissue and dry it with a soft cloth. For connectors, use a cotton-tipped applicator dipped in isopropyl alcohol, ensuring no residue remains, and follow with a dry applicator to remove debris.
