This space will use as scrap notes of my r&d and search of an Industrial Scale Automatic Book Scanner over the next few days.

Guiding Principles:

Fully-Automated
Reasonably Priced ( under 5 Lakh INR )
Atleast 500 pages/hour
Low Maintenance
Low Expertise Requirement
Smaller Physical Dimensions
Smaller Weight ( under 20 kg )
Zero Post-Processing ( no or negligible post processing such as cropping )
Scan Quality ( Readable with ease, 300 DPI, nothing over-fancy)

For now Mango Linear Scan fits the bill. But so unfortunately, the CEO Mr. Paul informed me that their Bar Scanner Manufacturer is no longer making those, which means Mango may not be available for purchase.

I contacted the CEO. He informed me that the parts supplier for the Scanning is no longer manufacturing those, therefore sales are halted indefinitely.
