Cleaning the Linear Imager Scanner
Routinely cleaning the exit window is required. A dirty window may affect scanning accuracy. Do not allow any
abrasive material to touch the window.
To clean the scanner:
1. Dampen a soft cloth with one of the approved cleaning agents listed above or use pre-moistened wipes.
2. Gently wipe all surfaces, including the front, back, sides, top and bottom. Never apply liquid directly to the
scanner. Be careful not to let liquid pool around the scanner window, trigger, cable connector or any other
area on the device.
3. Be sure to clean the trigger and in between the trigger and the housing (use a cotton-tipped applicator to
reach tight or inaccessible areas).
4. Do not spray water or other cleaning liquids directly into the exit window.
5. Wipe the scanner exit window with a lens tissue or other material suitable for cleaning optical material such
as eyeglasses.
6. Immediately dry the scanner window after cleaning with a soft non-abrasive cloth to prevent streaking.
7. Allow the unit to air dry before use.
8. Scanner connectors:
a. Dip the cotton portion of a cotton-tipped applicator in isopropyl alcohol.
b. Rub the cotton portion of the cotton-tipped applicator back-and-forth across the connector on the
Zebra scanner at least 3 times. Do not leave any cotton residue on the connector.
c. Use the cotton-tipped applicator dipped in alcohol to remove any grease and dirt near the connector
area.
d. Use a dry cotton tipped applicator and rub the cotton portion of the cotton-tipped applicator
back-and-forth across the connectors at least 3 times. Do not leave any cotton residue on the
connectors.
Cleaning the Linear Imager Scanner Cradles
Do not pour, spray or spill any liquid on the cradle. See Cleaning the Linear Imager Scanner for instructions
about cleaning the cradles.
To clean the cradle connectors:
1. Remove the DC power cable from the cradle.
2. Dip the cotton portion of a cotton-tipped applicator in isopropyl alcohol.
3. Rub the cotton portion of the cotton-tipped applicator along the pins of the connector. Slowly move the
applicator back-and-forth from one side of the connector to the other. Do not let any cotton residue remain
on the connector.
4. Rub all sides of the connector with the cotton-tipped applicator.

swab moistened with alcohol to gently clean contacts.
