Variable name; bug or deliberate?

[kneiser]

I have an Epson Perfection V39 flatbed scanner that I have implemented on Scanner-Server successfully. When I first tried to get Scanner-Server to recognise my scanner it would not.

After following error and log messages I traced the problem to "index.php, line 1257":

$OURCE=($SOURCE=='Inactive')?'':"--source ".shell($SOURCE)." ";

I changed "$OURCE" to "$SOURCE", and Scanner-Server then recognized the scanner. Everything has been fine since.

Also in "PHP File: index.php, line 1263":

$cmd="scanimage -d $DEVICE $OURCE-l $X -t $Y -x $SIZE_X -y $SIZE_Y $DUPLEX--resolution $QUALITY --mode ".shell($MODE)." $LAMP--format=$RAW"; I changed it to “SOURCE” but scanner stopped working. I had to change back to “$OURCE”.

Please clarify if anything needs to be looked in to further. `

On the configure tab under scanners click on scanner list: http://127.0.0.1/index.php?page=Device%20Notes click on the 1st link under your scanner i need the output you get on that page to properly fix your issue

the line you changed is used to select the input tray on a scanner, for example some printers have a flatbed and a doc feeder, you are using a standalone scanner, so i assume it only has a flatbad If you changed line 1257 to $OURCE=''; it should have the same effect as what you did

I need you to click the link starting with imagescan that page has what i need http://127.0.0.1/index.php?page=Device%20Notes&action=imagescan%3Aesci%3Agt-s650%3Ausb%3A%2Fsys%2Fdevices%2Fpci0000%3A00%2F0000%3A00%3A1d.7%2Fusb1%2F1-6%2F1-6%3A1.0 i could not give a direct link before as i did not know that very long link's text maybe there is a issue with a space in the source name? i am pretty sure it should support it

This command should put a scan on your desktop, does it not work? if not any error messages?

scanimage -d 'imagescan:esci:gt-s650:usb:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0' --source 'Document Table' -l 0 -t 0 -x 218.44 -y 299.72 --resolution 50 --mode 'Color' --format=pnm > ~/Desktop/Testscan_With_Source.pnm

the edit you did would have changed it to this:

scanimage -d 'imagescan:esci:gt-s650:usb:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0' -l 0 -t 0 -x 218.44 -y 299.72 --resolution 50 --mode 'Color' --format=pnm > ~/Desktop/Testscan_Without_Source.pnm

Command line: I changed to the Downloads directory as this is a LAMP server.

scanimage -d 'imagescan:esci:gt-s650:usb:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0' --source 'Document Table' -l 0 -t 0 -x 218.44 -y 299.72 --resolution 50 --mode 'Color' --format=pnm > ~/Downloads/Testscan_With_Source.pnm

[GM-Script-Writer-62850]

Your scanners geometry seems strange, I would expect the max value for -t and -y to be the same and -x and -l to be the same

Could you post your config/scanners.json file's content?

[GM-Script-Writer-62850]

This may not give the --br-x error: With source:

scanimage -d 'imagescan:esci:gt-s650:usb:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0' --source 'Document Table' -l 0 -t 0 -x 215.9 -y 279.4 --resolution 50 --mode 'Color' --format=pnm > ~/Downloads/Testscan_With_Source.pnm

Without Source

scanimage -d 'imagescan:esci:gt-s650:usb:/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0' -l 0 -t 0 -x 215.9 -y 279.4 --resolution 50 --mode 'Color' --format=pnm > ~/Downloads/Testscan_Without_Source.png

Assuming without source works all i should need to do is check for [read only] on the source line and if found treat it as inactive

With source:

Error Displayed: scanimage: unrecognized option '--source'

Without source:

Works fine!

[GM-Script-Writer-62850]

This should solve it: Commit #1e8d6cb (Only changes to index.php apply to this)

[GM-Script-Writer-62850]

*You need to re scan for scanners after making that change

Ok that did the trick! Thanx!
