There are numerous scanners available in current market. All scanners are not suitable for implementing OMR technology. For evaluation of multiple choice type answer sheets or application forms, we need high speed scanners with less manpower. ADF scanners are best recommended for OMR softwares as they can scan 15 to 50 pages per minute and can hold 50 to 100 sheets in the tray. Again, as the cost of ADF scanners are very high, we also recommend flatbed scanners which can scan 3 to 5 sheets per minute. Some of the flatbed and autofeed scanners are briefly sported which are best compatible to our OMR softwares.
