Canon's Instruction On Sensor Cleaning

This is an email in response to my question on how to clean the sensor of the 1D/1Ds. Anyone find this helpful??

From Canon...
The CMOS sensor in the EOS 1Ds corresponds to the film in a film-based
camera. If any dust or other foreign matter adheres to the CMOS sensor,
it may show up as a dark speck in the pictures you take. To avoid this,

follow the procedure below to clean the CMOS sensor. Note that the CMOS sensor is a very delicate component. If possible, you should have it
cleaned by a Canon Authorized technician.

While you clean the CMOS, the camera's power must remain on the whole
time. To make sure the power will not turn off while you clean the
sensor, connect the camera to a power outlet with the DC Coupler Kit or
use a fully charged battery pack. You will also need a rubber blower,
and the lens must be detached from the camera.

1. Insert the DC coupler or battery pack into the battery compartment
and set the power switch to the ON position.

2. In the menu, select "Sensor cleaning."

3. Select "OK." The LCD monitor will turn off.

4. Press the shutter button fully. The reflex mirror will lock up and
the shutter will open.

5. Clean the CMOS sensor. Use a rubber blower to carefully blow away any
dust or debris adhering to the sensor.

6. After the sensor has been cleaned, turn the camera off.

Be sure not to turn off the camera while cleaning the CMOS sensor. If
the power is turned off, the shutter will close and you may damage the
shutter curtain with the blower.

Do not use a blower brush. The brush can scratch the sensor.

Do not insert the blower tip inside the camera beyond the lens mount. If
the power goes out, the shutter curtain will close and the blower tip
may damage it.

Do not use a high-pressure blower or compressed air ("canned" air). The
air's extra pressure may damage the sensor, and the propellants and
gasses in compressed air may freeze the surface of the sensor.

We hope this information is helpful to you. Please feel free to contact
us if you have any further questions or concerns.

Thank you for choosing Canon.
