[sane-devel] Supported Epson Perfection 1260 produces 2 background stripe colours

[Julian H. Stacey]

could not get configuration for device 0x0402/0x9665 at 001:005: Insufficient memory
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Is that Normal ???????????????????

Oops, please ignore that line !
0x0402/0x9665 is some other internal USB device, not the scanner.

Cheers,
Julian

Hi Julian,

I have a USB scanner Epson Perfection 1260 (not a printer combo)
half working, using FreeBSD current (3 week old src/ & current
ports/packages) fresh installed sane back end, front end & xsane.
http://www.berklix.com/~jhs/tmp/epson_perfection_1260/
all with 2 background colours: yellow on left half of page, red on right.

I get a permission denied on the xsane.pnm but the other two PNM files
clearly show your problem.

http://www.sane-project.org/cgi-bin/driver.pl?manu=Epson&model=Perfection+1260&bus=usb&v=04b8&p=011d
shows a choice of 2/3 drivers:J epson2 & sane-plustek [& epkowa?]

Using this scanner with the epkowa backends requires a non-free plugin
that may or, more likely, may not work on FreeBSD. IIRC, the plugin is
built assuming GNU/Linux and links dynamically against glibc libraries.

The epson2 backend lists it as unsupported.

So, that leaves you with the plustek backend as your most likely
supporting backend.

# I've Cc:d it's maintainer just in case.

I wasn't sure how to specify driver,
Couldn't select driver from interactive xsane, nor from
xscanimage plustek:/dev/ugen1.5 # fails to open
xscanimage plustek:/dev/usb/1.5.0 # fails to open
setenv SANE_DEFAULT_DEVICE "plustek:/dev/ugen1.5" ; xsane # striped
setenv SANE_DEFAULT_DEVICE "epson2:/dev/ugen1.5" ; xsane # striped
setenv SANE_DEFAULT_DEVICE "epkowa:/dev/ugen1.5" ; xsane # striped
I've done mv ~/.[a-zA-Z]* X/ ; cd X
mv .[xX]* ~/ # for xauth
# so its nothing in old inherited .sane/ or similar dor file
Have I missed something ? Or is my scanner defective ?
PS various notes from my

sane-find-scanner -q
[...]

IIUC, you should not have to modify the plustek.conf file at all. Using
something like you do above (note that it should be `[usb]`) will likely
stop working as soon as you re-plug or power-cycle the device. On Linux
I'm sure it does, don't know for FreeBSD.

Maybe the log file from

SANE_DEBUG_PLUSTEK=127 scanimage [your-options-here] > out.pnm 2> log

can shed some light on your problem? Please use [your-options-here] to
set a small scan area so we don't get inundated with a multi-MB log file
here on the list ;-)

Hope this helps,

Yes, it was short term desperation to try to point to a known device
but my USB numbers were changing here too, presumambly as I added
or removed other USB devices. I'll comment it out. But keep the [] :-)

I dont know the code, if one could debug if swapping is happening OK ?

Is it concidence the white paper shows yellow then red exactly halfway
across the page.

BTW but probably irrelevant: scanner takes ages to start, I see the
default conf file has option warmup -1 = auto, I guess that's just
manufacturer being cautious.

plustek-usbhw.c: DBG( _DBG_READ, "--> Must swap data!\n" );
I dont know the code, if one could debug if swapping is happening OK ?

The usb_HostSwap() function that produces those last two debug lines is
simply a query whether swapping is needed. I'm not familiar with the
backend's code but the bits that use this function seems to be doing the
swapping on a per pixel basis and do so alright on cursory inspection.
At least for plustek-usbcal.c and plustek-usbimg.c. I'm a lot less sure
about the correctness of swapping in plustek-usbshading.c seeing code
patterns like

#ifdef SWAP_COARSE /* sometimes SWAP_FINE */
if (usb_HostSwap())
#endif
usb_Swap(buf, length)

which seems fishy at best.

Probably not but I have no idea why it would.

The scanner work OK in monchrome, output & log etc here:
http://www.berklix.com/~jhs/tmp/epson_perfection_1260/scanimage/5-small/files
SANE_DEBUG_PLUSTEK=127 scanimage --depth 8 --buffer-size=8 -x250 -y150 \
--mode Lineart > out.pnm 2> log

http://www.berklix.com/~jhs/tmp/epson_perfection_1260/scanimage/6-small/files
SANE_DEBUG_PLUSTEK=127 scanimage --depth 8 --buffer-size=8 -x250 -y150 \
--mode Lineart --resolution 300 > out.pnm 2> log

Using 8 bit colour & reducing buffer size from 32K to 8K didnt help.

Might it be some multi byte colour ordering problem ?
vi -c/usb_HostSwap \
plustek-usbcal.c plustek-usbhw.c plustek-usbimg.c plustek-usbshading.c
