6Maintenance

A patient’s tears may get on the nozzle and cause a secondary infection. Always use a cotton 
swab or other appropriate material that has been treated with disinfectant to wipe the nozzle. 

When dust or dirt is stuck on the tip of or inside the nozzle, press the CHECK button to blow it off.

•  Do not wipe or rub the optical component if there is dirt or dust on it. Doing so could scratch the 

surface of the optical component. 

•  Do not wipe the optical component with disinfectant ethanol, eyeglass cleaner, or silicone-

coated paper. Doing so could corrode the surface of the optical component or leave streaks.  
Also, wiping with too much lens cleaner causes streaking. 

•  For information about lens cleaning paper and lens cleaner, contact your sales representative or 

local Canon dealer. 

•  Be sure to put the cap over the optical component of the nozzle when the TX-20 is not in use. 

Clean the optical component of the nozzle as indicated below when dust is on it, or if it is stained with 
tears. 

Blow away any dust or dirt. 

Remove the brush from the blower brush and blow off the dust on the optical component.

Wipe the optical component. 

Slightly dampen a lens cleaning paper with lens cleaner and lightly wipe the optical component. Wipe 
it again if it needs it.
