Dust cleaning of the imaging surface (LPF surface)

Make sure that DIA (Digital Image Analyzer) displays "PASS" in the dust check when
returning repaired products to users.

⑴DIA Software Guide:

Detects dust elements on designated image and
counts the number. Based on the location, size, and
number of dust specs, DIA judges "PASS" or "FAIL".
1. Take a picture
Shooting condition
・EF 50/1.8 lens
・Av Priority AE (F22)
・ISO 100, AEB
・JPEG Large/Fine
・Light Source (EF-1,8000 or Light Box)
2. Download the image to PC.
3. Open the JPEG file on DIA.
4. The result of the judgement
In case of "FAIL", click the No. and check
where the dust is located if necessary. Then,
clean the dust.

⑵Dust Loupe (CY9-1132):

Use the dust loupe set as a service tool to check
dust. The imaging surface from which all dust
viewable with the loupe has been cleaned should
meet the cleaning standard.

Indicator Plate can be blown out through these holes.
