HP Scanjet 3670 is very slow when scanning at 600-1200 dpi

[Csipak Attila]

Binary package hint: simple-scan

Scanner model: HP ScanJet 3670
Ubuntu-release: 16.04 LTS

Relevant packages and versions:

libsane 1.0.25+git20150528-1ubuntu2
simple-scan 3.20.0-0ubuntu1
xsane 0.999-3ubuntu1

When I use Simple Scan with "scan as photo" option at higher resolutions, the scanning process is very slow: on 600 dpi, it takes 5-6 minutes; on 1200 dpi it would take about an hour to scan a page (to be honest, I cancelled the process about halfway).

In contrast, if I use xsane with "factory settings" + 1200 dpi, the whole process takes about 6 minutes.

This has been an issue since Lucid.

Csipak Attila, thank you for reporting this and helping make Ubuntu better.

To see if this is already resolved, could you please test for this via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Csipak Attila (corphicks)]

Yup, I tested it with the daily live, and the results are the same.

Please try the HPLIP driver. It should be resolved with this driver.
