With 0.9.14, I can reproduce the problem, which seems to relate to
the --batch* options passed to scanimage. See below.

Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write PNM image data to
standard output.
Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), and %i (index number)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm' or
`out%d.tif' by default depending on --format
--batch-start=# page number to start naming files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase number in filename by an amount of #
--batch-double increment page number by two for 2sided originals
being scanned in a single sided scanner
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size change default input buffersize
-V, --version print version information
Options specific to device
`net:sane:hpaio:/net/HP_LaserJet_3052?ip=192.168.14.31':
Scan mode:
--mode Lineart|Grayscale|Color [Grayscale]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 75|100|150|200|300|600|1200dpi [75]
Sets the resolution of the scanned image.
Advanced:
--contrast 0..100 [50]
Controls the contrast of the acquired image.
--compression None|JPEG [JPEG]
Selects the scanner compression method for faster scans, possibly at
the expense of image quality.
--jpeg-compression-factor 0..100 [10]
Sets the scanner JPEG compression factor. Larger numbers mean better
compression, and smaller numbers mean better image quality.
--batch-scan[=(yes|no)] [no]
Guarantees that a "no documents" condition will be returned after the
last scanned page, to prevent endless flatbed scans after a batch scan.
For some models, option changes in the middle of a batch scan don't
take effect until after the last page.
--source Auto|ADF [Auto]
Selects the desired scan source for models with both flatbed and
automatic document feeder (ADF) capabilities. The "Auto" setting means
that the ADF will be used if it's loaded, and the flatbed (if present)
will be used otherwise.
--duplex[=(yes|no)] [inactive]
Enables scanning on both sides of the page for models with
duplex-capable document feeders. For pages printed in "book"-style
duplex mode, one side will be scanned upside-down. This feature is
experimental.
Geometry:
--length-measurement Unknown|Unlimited|Approximate|Padded [Padded]
Selects how the scanned image length is measured and reported, which
is impossible to know in advance for scrollfed scans.
-l 0..228.6mm [0]
Top-left x position of scan area.
-t 0..381mm [0]
Top-left y position of scan area.
-x 0..228.6mm [228.6]
Width of scan-area.
-y 0..381mm [381]
Height of scan-area.
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

Now if I run that command line, I get to the source of the problem:
piper:~> scanimage
--device-name='net:sane:hpaio:/net/HP_LaserJet_3052?ip=192.168.14.31'
--mode='Grayscale' --contrast='50' -x 210 -y 297 -l 0 --compression='JPEG'
--resolution='200' --batch-scan='yes' -t 0 --batch --source=Auto >|
/tmp/scan.pnm
Scanning -1 pages, incrementing by 1, numbering from 1
Scanning page 1
scanimage: sane_start: Document feeder out of documents
To fix it, I have to remove the two --batch* options. So in fact,
this may actually be a bug in scanimage/sane-utils, but that package
has not changed since May, and the problem started to appear in
June.
