The +following scanners work with this backend: +.PP +.RS +Model: +.br +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- +.br +Astra 610P +.br +Astra 1220P +.br +HP3200C +.br +Astra 1600P +.br +Astra 2000P +.br +Genius ColorPage-Life Pro +.br +.RE +.PP +This backend handles 75x75, 150x150, 300x300, 600x600 and 600x1200 for 1220P/1600P/2000P +dpi scan resolutions, and 75x75, 150x150, 300x300 and 300x600 for 610P. In color and gray +levels, there is a software lineart mode. +.PP +The new generation models share a newer version of the 610P ASIC embedded in an EPAT chip. +Only parts such as CCD and ADC change from +one to another. They even all reports being UMAX Astra 1220P via IEEE1284. +There isn't a software method to recognize them properly. Under windows, model is +set by the driver installed, regardless of the hardware. +.PP +.TP +.B EPP/ECP MODES ONLY +The current version of the backend uses only EPP or ECP mode to communicate +with the scanner. PS/2 mode isn't implemented. The 610P only use SPP. It is +recommended that you set your parallel port to EPP in BIOS with the current +version of this +backend. You can leave it to ECP or ECP+EPP, but in this case you may not use +ppdev but only direct hardware access if you have to use ECP. ECPEPP will only +work if you use a 2.4 or 2.6 kernel with ppdev character device support. +.PP +This backend does support parport sharing only +.I +if you have a kernel with ppdev support. +.I +.PP +Note that if you don't use the ppdev character device, the backend +needs to run as root. To allow user access to the scanner +run the backend through the network interface (See +.BR saned (8) +and +.BR sane\-net (5)). +A more relaxed solution (security wise) is to add suid bit to the frontend +(See +.BR chmod (1)). +The backend drop root privileges as soon as it can, right after gaining direct +access to IO ports, which lessen risks when being root. + +.SH "DEVICE NAMES" +This backend expects device names of the form: +.PP +.RS +.I port value +.RE +.PP +Where +\fBvalue\fR is : + +.RS +.TP +auto +autodetect all parallel ports and probe +them for scanner +.TP +safe\-auto +autodetect all parallel ports and probe +them for scanner, but does not try direct +hardware access +.TP +.I /dev/ppi0 +uses *BSD ppi device, depending on the +number of available parallel port, you +have to use +.IR /dev/ppi1 , +.IR /dev/ppi2 ", ..." +.TP +.I /dev/parport0 +uses Linux ppdev device, depending on the +number of available parallel port, you +have to use +.IR /dev/parport1 , +.IR /dev/parport2 ", ..." +.TP +0x378 +does direct hardware access on the given +address.

Empty lines and lines starting with a hash mark (#) are +ignored. +.PP +The eight options supported are +.BR red\-gain , +.BR green\-gain , +.BR blue\-gain , +.BR red\-offset , +.BR green\-offset , +.BR blue\-offset , +.BR astra , +and +.BR buffer . + +Options +.BR red\-gain , +.B green\-gain +and +.B blue\-gain +allow you to adjust the sensitivity of your scanner for the given color. Values +range from 0 (lowest gain) to 15 (highest). If the advanced option "Gain" isn't +checked in the frontend, the backend does automatic gain calibration, and do not use +user provided values. + +.PP + +Options +.B red\-offset +, +.B green\-offset +and +.B blue\-offset +allow you to adjust the offset of your scanner for the given color. Values +range from 0 (lowest offset) to 15 (highest). +.PP + +Option +.B astra +allows you to change the model of your scanner. Current auto detection is based +on side effects on scanning when using 1220P command set on other models, so +it may fail on unknown hardware combination. Valid values are 610, 1220, 1600 +and 2000. It is useful only when autodetection fails to detect properly +your scanner model. If your scanner work properly but is reported wrongly, +let it be that way. +The only valid case to change the model is when your scanner produces "black" or +"inverted" scans. In this case you can put the model. Be aware that it will +prevent scanner model autodetection. +.PP + +Option +.B buffer +allows you to change the size of the scan buffer. The size must be specified in +bytes. The default value is 2 megabytes. Decreasing this value will improve the +smoothness of progress bar in the frontend, but will stall the +scan more often. + +.PP + + + +.SH "FILES" +.TP +.I /etc/sane.d/umax_pp.conf +The backend configuration file (see also description of +.B SANE_CONFIG_DIR +below). +.TP +.I /usr/lib64/sane/libsane\-umax_pp.a +The static library implementing this backend. +.TP +.I /usr/lib64/sane/libsane\-umax_pp.so +The shared library implementing this backend (present on systems that +support dynamic loading). + +.SH "ENVIRONMENT" +.TP +.B SANE_CONFIG_DIR +This environment variable specifies the list of directories that may +contain the configuration file. On *NIX systems, the directories are +separated by a colon (`:'), under OS/2, they are separated by a +semi-colon (`;').
