4
Scanning
Simultaneous creation of up to six images
Optical lens > 10 mm, sharpness-depth-area 3 mm
Optical und ultrasonic double feed control
Energy saving / live cycle extending Mode
Consistent jam handling:no document is lost or double captured due to physical jams
cleanness check program: detects white - and black dirt spots

Scanning
Pockets 2 – 12 why:
if the document is scanned skewed or de-skewed
if the very important questions are filled / are readable(if OMR, OCR, Barcode)
if there are fingerprints on the questionnaire or not
if the Barcode/OCR/OMR numbers (not ICR) numbersare in the given range
if there are double entries – we check the unique number
if there are (colour) copies used
if there are mismatches in quantity:Batch header shows 50 and only 40 are scanned
Transport stop can be programmed to clarify the issue

Scanning
Customer:
I have a printer and print since long my own questionnaire
…I learnt from the internet that it is just a matter of software …
Before printing we should be consultedto give best advices, we will test and optimize.
Single side printing or higher scaled paper is necessary(shine through factor = opacity)
Paper should be white without any spots inside
Discuss different methods before making big investments

The Path to Recognition
Perform proper clean-up and imagepre-processing
Analyze individual page layout
Dynamically locate fields of interest
Character recognition(numeric handwriting, voted)
Compile results

Quality assurance
Form design with scanning quality check
Before delivery of paper scanning quality check
Confirm the quantity of forms
Make use of Trial Census experience
Establish checks for essential criteria only
Make day to day checks during the running Census
As soon as possible check the results and verify
