AXIS 1650 scanning support is limited to specific Canon devices only: https://www.axis.com/techsup/prtsrv/axis_1650/printers_eur.htm In theory, it could work as generic USB-over-TCP device but it does not. The firmware probably includes a whitelist of supported devices or some other way to know

I'm confused- are you proposing to add a new backend that lets pixma scanners work over this AXIS machine, but not other scanners? allan On Fri, Mar 20, 2020 at 2:58 PM Rolf Bensch wrote: > > Hi Ondrej, > > Many thanks for your message. > > Am 20.03.20 um 18:44 schrieb Ondrej Zary: > > Hello, >

Hi, I don't look through Canon's marketing policy how they name their devices. It's not such easy as it looks like: EU = 5, US = 7. E.g.: For Canon imageClass MF4700 Series I found these models: MF4720, MF4730, MF4750, MF4770 and MF4780 (1x Asia, 3x Europe, 1x US). For other models Canon is

Rolf, please do not add a break dependency against ippusbxd. It is most probably only some models which cause problems. If you want to use eSCL via the network it does not matter whether ippusbxd is running or not. You only need to make sure to select the correct scanner entry in the client
