Cleaning the Sensor on IQ4
The Phase One IQ4 Digital Back should always have the protective sensor
cover fitted when not attached to a camera. Dust may accumulate on the IR
filter of the sensor, which will degrade the image quality if not removed. When
cleaning the sensor, please use the Phase One Sensor Cleaning Kit that is
supplied with the IQ4.
Instructions for sensor cleaning:
1. First try to remove any dust or debris with a rocket air blower. This will
ensure that no hard particles like sand can scratch the IR filter during the
following steps.
2. Locate the small scraper in the supplied Sensor Cleaning Kit and use either
the wide (42 mm) or normal (38 mm) end that matches the width of your
sensor. Ensure that no dust or loose material is present on the edge of the
scraper.
3. Select a cloth from the Sensor Cleaning Kit and fold it over the scraper so
that you have two layers of cloth.
4. Apply 2-3 drops of Eclipse® cleaning fluid from the Sensor Cleaning Kit to
the edge of the folded cloth.
5. In one motion, swipe the surface of the sensor from one end to another. Do
not swipe a second time in the opposite direction.
6. Inspect if the sensor is clean by holding it into the light. If necessary, move
the cloth layer one cm on the scraper and repeat the process. Never swipe two
times with the same area of the cloth as the removed dirt could risk being
reapplied to the sensor.
For quick sensor cleaning during work in the field you can use an air blower or
the supplied e-wipe® wet tissues. These can be used with same procedure as
outline above, just skip adding the Eclipse® cleaning fluid.
Note: The IR filter (Infrared Reduction Filter) is permanently mounted on top
of the sensor. The filter may not be removed for several reasons:
1. Focus accuracy is dependent on the presence of the IR filter.
2. It is only possible to remount the filter without dust degrading the sensor
if you have access to special clean room facilities.
3. The Phase One Product Warranty will be void.
WARNING: Never use compressed air unless the product is made specifically
for photographic equipment, since the propellant can leave residue on the
surface that can be extremely dicult to remove.
