deskjet 3520 scanning with jpeg artifacts

Asked by Znerole

Hello everyone,

I have just bought a HP Deskjet 3520 and while network setup and printing worked like a charm, scanning is pretty bad, because I cannot disable scanner side JPEG compression with rather poor quality settings. In xsane's advanced settings, JPEG is the only selectable compression. Changing the compression manually to "none" in the corresponding drc file hast Nov effect.

Same applies for hp-scan, which produces JPEG artifacts no matter what compression I select.

I'm on Ubuntu 13.10, hplip version is 3.13.09.

Thanks you!

UPDATE: I upgraded to hplip 3.13.10 and now I get the unsatisfactory message "error: Unable to set option compression to value None" when I run hp-scan. I hope this is not a limitation of the scanner as this would render it useless for me.

HPLIP Scanning supports only JPEG compression. As you said, in hplip 3.13.10, you're getting error for hp-scan, unlike in 3.13.9. Please run "hp-uninstall" and do a fresh installation of 3.13.10. Restart your printer and check again for scanning.

That was on two different machines. And it doesn't work in hplip 3.13.09 either, it just doesn't supply any error message.

Btw, what does this mean: "HPLIP Scanning supports only JPEG compression"? Is it not possible to disable the compression? I've seen plenty of forums where people are able to set compression to "raw" or to "none".

Well, to make myself clear: Scanning itself works with both versions of HPLIP, but only with this hideous JPEG artifacts. I'm trying to scan text documents and don't care about speed, but JPEG artifacts on text is not really acceptable.

Thank you!

Bump!

Can someone at least tell me if this is a hardware/firmware issue with this printer model (HP Deskjet 3520) or of it's a driver issue. If it's a problem with the model, I will definitely have to return it. If it's a software issue, I can hope for fixes (or look into it myself).

Thank you!
