I can further confirm that this escl buggy driver affects other scanners, e.g. Epson XP-830 just to name *one* but there are endless Escl network printers/scanners these days.
Using the PPA:- https://launchpad.net/~sane-project/+archive/ubuntu/sane-release version 1.0.32 *does* work a lot better!. I have really come to the conclusion that the sane-release PPA is very backwards-compatible with all the existing software-tools, simple-scan, xsane, skanlite, libreoffice, xscanimage, gimp, gscan2pdf, ... in all cases I have tested, the 1.0.32 sane-release ppa version of sane backends works the same or better as the focal 1.0.29 version without requiring any software to be re-compiled. 'gscan2pdf' is notably more functional than simple-scan in terms of being able to auto-rotate back- sides of scanned auto-feed pages. The trouble comes, helping users without having to do all sorts of searching and having to 'find out' bugs hard way.... Can a new point- release of focal provide sane-backends and sane-airscan backported, well-tested packages? As to when to get users ipp-usb (or not) installed, is another matter entirely, that also matters. For some ipp-usb makes the scanning work well, for other cases not, needs to be NOT running to support legacy scanner drivers!... I suspect for 22.04 ipp-usb should be provided by default. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1897962 Title: Out of Memory Error with Brother DCP-J7720W Status in sane-backends package in Ubuntu: Fix Released Bug description: Installed XSane from the repository but when I scan the viewer screen is blank and if I try to save I get "Error during save: out of memory" I believe that escl driver in 20.04 sane-backends is a problem and it is related to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=962539 sane-backends 1.0.31 should be considered for focal-backports and that if possible, escl driver could be individually SRU (Stable release update) in focal-updates. ppa:sane-project/sane-git fixes the issue.
