Xsane will not scan complete document in "lineart" mode

[William T. Lowther]

Ubuntu 16.04.1
Xsane .999
Scanner is All-in-1 HP Photosmart 6520
Scanning function operates normally when the scan mode in the main window is set at either Color or Gray. With scan mode at Lineart, the "Preview" function shows the complete document, but when "Scan" is selected the scan bar travels a very short distance and returns to its normal docking position. The resultant image shows only the top 5-10% of the document. The window left of the "Scan" button, showing the size of the image, always shows 1MB for the Lineart scan, but 24 MB for a Color scan (either PNG or JPEG).

Output of:
$ hp-scan -m lineart -r 100 -o tempa.png
HP Linux Imaging and Printing System (ver. 3.16.3)
Scan Utility ver. 2.2

END

Note that there is no file generated for "tempa.png".
Also, the above command for mode gray or color successfully scans the entire document.

Lastly, the output of the following terminal command successfully scans the complete document for modes lineart, color, and gray:

$ scanimage -d hpaio:/usb/Photosmart_6520_series?serial=TH32B1109805TZ --resolution 300 --mode lineart -x 215 -y 295 > filename.pbm

Same for me.

Kbuntu 16.04
OfficeJet Pro 8500

Purged and deleted ~/sane/xsane/

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem with HP Deskjet 1050A.
I was successfully using "lineart" mode with xsane since mid-2015, I discovered the bug on the first days of year 2017, probably after installing a few monthes of packages updates.
Now I have to fall back to command-line "scanimage" and then convert tiff to pdf.

I'm experiencing this problem as well.
Printer: HP Officejet Pro 8720.
error: Did not read enough data from scanner (I/O Error?)

Anyone found a solution yet?

I can confirm that this problem still exists on Kubuntu 21.04 with an HP Deskjet 1050A.
