Hi,
I have a Ricoh IS450DE Scanner which I'd like to write a sane-backend driver.
As I have no experience whatsoever writing a driver, I was wondering if
any other Sane users would be interested in helping out. Mattias Kregert was
kind enough to mail me the SCSI Specifications for the IS450 Famil

Hi,
I've begun preliminary testing of the Ricoh IS450 scanner.
I began by copying all the ibm* backend files to hs2p* backend files and
simply globally substituting as follows
:%s/ibm/hs2p/g
:%s/IBM/HS2P/g
and added IS450 to the string comparison in hs2p.c
as well as #defines for papersize L

I've been working on writing a driver (hs2p) for the Ricoh IS450/IS420
scanners. I've drawn mainly from the bh and ibm drivers, but also a little
from the avision and canon drivers.
My plan was to split the code into several parts:
hs2p.c{sane_init(), sane_get_devices(), sane_open(),

Hi,
I've been debugging my hs2p Ricoh IS450/420 driver and am having a problem with
set_window()
returning with ILLEGAL REQUEST:
[hs2p] sane_start: sending SET WINDOW DATA
[hs2p] >> set_window
[hs2p] set_window: SET WINDOW COMMAND Transfer Length = 648 (should be 648)
[hs2p] set_window: SET WIND
Ricoh IS450 hs2p backend update:
I found the bug in my set_window() command.
The Manual said that the default value of the double-byte bit-order was
that bits 0-2 were '0' and the remaining bits '1'
which conflicted with the further specification that bits 6-4 were reserved and
hence unset.

Hi,
I finally got my hs2p driver to do basic scanning:
# scanimage -T -d hs2p:/dev/sg0
scanimage: scanning image of size 4672x6787 pixels at 1 bits/pixel
scanimage: acquiring gray frame, 1 bits/sample
scanimage: reading one scanline, 584 bytes... PASS
scanimage: reading one byte... PA

Hi,
My hs2p Ricoh driver seems to be working just fine with the cmdline tool
scanimage.
However, when I try scanning with xscanimage or xsane, I get a popup error msg:
"Failed to start scanner. Invalid argument"
If I retry, I get "Failed to start scanner. Device Busy."
Nothing more is written to
Finally figured out why I wasn't seeing any DBG() statements with Xsane:
I was connecting to the scanner over the network.
My scanner runs off a scsi card in an old Pentium III with no monitor, so
I ssh'd to the remote PIII computer to edit my hs2p backend and to run
scanimage, so naturally my DB
I've finally got the major features of the IS450 working
but would appreciate some advice on implementing reading duplex window data in
SANE.
in sane_start() I have something like:
sane_start()
{
select Flatbed/ADF scan source
if ADF select simplex/duplex (continuous?)
select endorse

OK.

I looked over the fujitsu backend and see why it must buffer the RGB frames
which are not returned sorted by page side.
For my hs2p backend, I only have one GRAY frame, the first window of which
is the image data for the 1st side, and the 2nd window for the 2nd side.
So all I need is a boolean flag
The hs2p backend is basically finished, except for adding support for
continuous scanning and support for uploading custom halftone patterns
and gamma vectors. I do not plan to add support for reading/changing IPU
parameters since I don't have a scanner with such an option. Nor do I plan
on adding

I've been debugging my hs2p backend and have a question about
BRIGHTNESS/CONTRAST controls.
Following the ibm, bh, and sp15c backends, I initialized a SANE option
OPT_BRIGHTNESS in
init_options()

s->opt[OPT_BRIGHTNESS].name = SANE_NAME_BRIGHTNESS;
s->opt[OPT_BRIGHTNESS].title = SANE_TITL

I routinely routinely use Xsane to scan documents
directly to pnm
(Portable aNy Map) format, which I then convert to
muli-page pdf
files using netpbm tools. If the ink on a document is
When I use xsane with the sp15c backend, there is a weird annoying bug related
to the drop-down lists for the xres and yres in Save and View modes:
In sp15c.c the x/y res are set to the following:
static const SANE_Int resolution_list[] =
{11, 0, 60, 75, 80, 100, 120, 150, 200, 240, 300, 600};

I decided to do some testing on the avision backend with the Fujitsu SP15C.
The first major difference I've noticed, is that the avision backend
monopolizes the scanner so that only one program can use the scanner while
that program is running, i.e. the first user who runs xsane will see the

I suppose an argument can be made for both approaches to locking, but
users sharing a network scanner must coordinate their usage by some means.
Somebody has to
