sane-hp5590 - SANE backend for Hewlett-Packard
4500C/4570C/5500C/5550C/5590/7650 Workgroup/Document scanners
.SH DESCRIPTION
.PP
The
.B sane-hp5590
library implements a SANE (Scanner Access Now Easy) backend that provides access
to the following Hewlett-Packard Workgroup/Document scanners:
.IP \[bu] 2
ScanJet 4500C
.IP \[bu] 2
ScanJet 4570C
.IP \[bu] 2
ScanJet 5500C
.IP \[bu] 2
ScanJet 5550C
.IP \[bu] 2
ScanJet 5590
.IP \[bu] 2
ScanJet 7650
.PP
If you own a scanner other than the ones listed above that works with
this backend, please let us know this by sending the scanner\[cq]s exact
model name and the USB vendor and device ids (e.g.\ from
.IR /sys/bus/usb/devices ,
.BR sane-find-scanner (1)
or syslog) to us.
Even if the scanner\[cq]s name is only slightly different from the
models mentioned above, please let us know.
.SH OPTIONS
.PP
The options the backend supports can either be selected through command
line options to programs like
.BR scanimage (1)
or through GUI elements in
.BR xscanimage (1)
or
.BR xsane (1).
Valid command line options and their syntax can be listed by using:
.IP
.nf
\f[C]
scanimage --help -d hp5590:interface:device
\f[R]
.fi
.PP
where \f[I]interface\f[R] and \f[I]device\f[R] specify the device in
question, as in the configuration file.
Add
.B --all-options
to also list the hardware read-out options.
The
.B \-d
parameter and its argument can be omitted to obtain information
on the first scanner identified.
.PP
Use the command:
.IP
.nf
\f[C]
scanimage -L
\f[R]
.fi
.PP
to list all devices recognized by your SANE installation.

\[lq]TMA Slides\[rq] - Slide scanning with transparent media adapter.
(Not fully supported by hp5590 backend).
.IP \[bu] 2
\[lq]TMA Negatives\[rq] - Negative film scanning with transparent media
adapter.

.RE
.TP
.B --resolution \f[I]res\f[R]
Set the resolution of the scanned image in \f[B]dpi\f[R].
\f[I]res\f[R] must be one of: 100, 200, 300, 600, 1200, 2400.
.PP
Default settings: Lineart, Flatbed, 100dpi.
.TP
.B --extend-lamp-timeout[=yes|no]
Extend lamp timeout period.
no = 15 minutes, yes = 1 hour.
(Default: no)
.TP
.B --wait-for-button[=yes|no]
Wait for button press before scanning starts.
(Default: no)
.TP
.B --preview[=yes|no]
Request a preview-quality scan.
(Default: no)
.TP
.B --hide-eop-pixel[=yes|no]
Hide end-of-page indicator pixels and overwrite with color of next
neighbor pixels.
(Default: yes)
.br
The scanner uses the last pixel in every scan line for storing the
end-of-page status.
This is needed to detect the end of the document sheet when the
automatic document feeder (ADF) is used.
Unfortunately the end-of-page pixels are also generated in flatbed
scans.
It is recommended to hide these pixels.
.TP
.B --trailing-lines-mode \f[I]mode\f[R]
Filling mode of trailing lines after end of page when automatic document
feeder (ADF) is used.
\f[I]mode\f[R] must be one of: \[lq]last\[rq], \[lq]raw\[rq],
\[lq]raster\[rq], \[lq]white\[rq], \[lq]black\[rq], \[lq]color\[rq].
(Default: \[lq]last\[rq])
.RS
.IP \[bu] 2
\[lq]last\[rq] = repeat the last scan line (recommended),
.IP \[bu] 2
\[lq]raw\[rq] = read raw scan data (not recommended),
.IP \[bu] 2
\[lq]raster\[rq] = generate black and white pixel pattern,
.IP \[bu] 2
\[lq]white\[rq] = white pixels,
.IP \[bu] 2
\[lq]black\[rq] = black pixels,
.IP \[bu] 2
\[lq]color\[rq] = RGB or gray colored pixels (see next option).
.RE
.TP
.B --trailing-lines-color \f[I]n\f[R]
Set color value for filling trailing scan lines in trailing lines mode
\[lq]color\[rq] (see previous option).
(Default color: violet)
.br
The RGB color value must be specified and calculated as 65536 * r + 256
* g + b, with r, g, b being values in the range of 0 ..
255.
.SH READ OUT OPTIONS
.PP
The following options allow reading out the button state, counter value,
color setting, and the state of document in ADF.
This can be used to programmatically control corresponding scanner
options like switching between \f[I]flatbed\f[R] and \f[I]ADF\f[R] mode,
or triggering post processing tasks after scanning.
.TP
.B --button-pressed
Get the id of the last button pressed.
Id is one of \[lq]none\[rq], \[lq]power\[rq], \[lq]scan\[rq],
\[lq]collect\[rq], \[lq]file\[rq], \[lq]email\[rq], \[lq]copy\[rq],
\[lq]up\[rq], \[lq]down\[rq], \[lq]mode\[rq], \[lq]cancel\[rq].
.br
The scanner stores the id of the last button pressed until it is read.
After read out, the state is reset and subsequent readings will return
\[lq]none\[rq].

.TP
.B --color-led
Get the state of the color LED indicators.
The state is either \[lq]color\[rq] or \[lq]black_white\[rq].

.TP
.B --counter-value
Get the counter value as shown on LCD.
The value is in the range of 1 ..
99.

.TP
.B --doc-in-adf
Get the state of the document-available indicator of the automatic
document feeder (ADF).
The state is either \[lq]yes\[rq] or \[lq]no\[rq].

.SH HINTS FOR USERS OF SCANBD
.PP
.BR scanbd (8)
is a scanner button daemon, which can read scanner
buttons and trigger scan actions.
.PP
Do not use the old
.BR scanbuttond (8)
interface with hp5590.
It is outdated and shall not be used any more.
The regular interface of
.BR scanbd (8)
is fully supported by the current version
of the \f[I]hp5590\f[R] backend.
.PP
This example shows a minimum configuration file and the corresponding
script file for
.BR scanbd (8)
to be included in
.IR scanbd.conf .
