Recommended scanners for use with Snap Scanning module

We have identified a number of scanners that work well with Snap. They are from the major manufacturers in the field, namely Canon, Fujitsu and Kodak and all have automatic document feeders to hold the questionnaires. It is not a definitive list, and should be regarded as a guideline, as there are many others on the market that do also work with Snap.

We have created 3 categories based on volume of usage, from Occasional Use (up to 500 sheets/day) to Regular Use (up to 1,000 sheets/day) to Heavy Use (for 1,000+ sheets/day).

Manufacturer’s claims for speed are generally very optimistic. We have adjusted these downwards based on our experience in scanning questionnaires and the quoted Scan Speeds are based on double-sided Snap questionnaires.

For further advice on which model best suits your requirements please contact your preferred hardware supplier. When considering scanners not listed here please make sure they are supplied with an ISIS driver. Although Snap Surveys endeavours to confirm that all of the scanners listed here are fully compatible with our software it is not possible for us to check all variations within a model and its drivers.
