<div>Hello,</div>

<div>I've just bought a Canon Lide 220 scanner but I can't make
it work at 2400 or 4800 dpi.</div>
<div>The scanner is supported 100% from 75 to 4800 dpi as of <a href="http://www.sane-project.org/sane-mfgs.html#Z-CANON" target="_blank" rel="noreferrer">http://www.sane-project.org/sane-mfgs.html#Z-CANON</a>.</div>
<div>I'm using Ubuntu 19.04 and sane 1.0.27.</div>
<div>Tried using simple-scan and genesys library on Gimp
(2.10.8), if resolution is 2400 simple-scan freezes same thing
on GIMP from 1200dpi and up.</div>
<div>I need 2400 or 4800 dpi scan of little areas (2cmx2cm) of
documents.</div>
<div>Can anyone help me?</div>
<div>Thanks.<br>

<p>I think I heard something about 2400 DPI on Canon LiDE, but don't
remember what. <br>
</p>
<p>Did you try installing latest sane git snapshot from PPA <a href="https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git" target="_blank" rel="noreferrer">https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git</a>
?</p>
