Finns en del varningar angående att luft på burk kan innehålla ämnen som kan frysa sensorn. Canon rekommenderar att man använder en "rubber blower" som används för att för hand pumpa luft mot sensorn.
Citerar sidan 40 manualen till 350D vad gäller rengöring av sensorn.
During the sensor cleaning, never do any of the following that would turn off the power. If the power is cut off, the shutter will close and it may damage the shutter curtains and image sensor.
- Set the power switch to <OFF>.
- Opening the CF card slot cover.
- Opening the battery compartment cover.
Other tips and warnings:
- Do not insert the blower tip inside the camera beyond the lens mount. If the power goes out, the shutter will close and the shutter curtains and image sensor may be damaged.
- Use a blower not attached with a brush. A brush can scratch the sensor.
- Never use canned air or gas to clean the sensor. The blowing force can damage the sensor or the spray gas can freeze the sensor.
- When the battery is exhausted, the beeper will sound and the battery icon will blink on the LCD panel. Set the power switch to <OFF>, replace the battery, and start over.
- You cannot clean the sensor if Battery Grip BG-E3 (optional) is attached to the camera and size-AA batteries supply the power. Use AC Adapter Kit ACK700 (optional) or use a battery having sufficient power.
