How to choose an A4 scanner for networking?

Question

HP

Good day to all. The task arose to organize a public scanner for A4 papers. The scheme is as follows:
- a person approaches the scanner and puts a pack of paper into it
- selects a scanning profile (jpg / PDF, resolution) and presses "Start"
- Takes scanned documents from the balls at the workstation
If anyone used an HP 425dn MFP, then all this is there yes, but not satisfied with the performance of the scanner, in addition, under heavy load, you often have to service the automatic document feeder. There are the following models in mind:
HP ScanJet N6350
Brother ADS-2600W
However, neither one nor the other did not work (yuzal HP 425dn).
Question to device owners: what jambs were noticed during operation?
What else can you advise for 20-30t.r.?
Z.Y. Do not offer a bunch of linux / win + USB scanner.
Thank you all in advance.

Answer 1

According to the description, they do not know how to scan in a ball
. We have a one-class Brother Canon in operation, very high speed (maybe single-pass), but you need to put the stack very evenly + it is not possible to scan passports. Therefore, everyone continues to use the kyocera fs-1035 (m2035, 1128) and it is in the task corresponding to the description: those in the ball (also able to send to mail and ftp) have devices that have scanned 50000 pages, while in terms of the scanner (and it is double-sided) by rubbing and cleaning from putty never had to resort to repairs.
425 is also there, everything is the same, the automatic feeder is generally a weak point for HP non-enterprise series.

Answer 2

We use Canon DR-M140
Among other things, I like:
- high speed (less than a second for 1 sheet on both sides!)
- to start scanning you need to press just ONE button, and it is scanned immediately, you do not need to confirm anything before and after the scanning process .
This model was bought back in 2007, still works without problems.
Now I myself work in another company, I also want to take one - the model has already been updated, the case is a little different.
