Introduction to Scanning 

SANE compatible applications such as XSANE, Kooka, GIMP and OpenOffice.org on the computer to which the MFP is connected can scan using the locally connected e‑STUDIO MFP connected and any e-STUDIO MFP connected to other Linux PCs on the LAN where the CUPS printer and SANE scanner drivers have also been installed. They can also scan using any e‑STUDIO MFP connected to a Windows PC on the LAN if the Viewer V2 Windows Printer and Scanner drivers are installed there and remote scanning was enabled during installation.

Unlike Windows, where the TWAIN scanner driver provides a single TWAIN dialog that is used by all TWAIN compatible Windows applications, each Linux SANE compatible application creates its own SANE scanner dialog. This approach means that the Linux application’s UI looks the same for all scanners but it will probably vary between Linux applications.

SANE provides no mechanism to change capabilities dynamically. Therefore, unlike Windows TWAIN, when paper is inserted into the MFP’s document feeder the options shown by a Linux application’s SANE dialog will not change to reflect this.

Scanner Sources 

Depending on the feeder options installed on your e-STUDIO you will see the following options in the e-STUDIO’s SANE scanner driver’s Source option:

Flatbed

This option is shown if no automatic document feeder is installed.

The page on the MFP’s flatbed/platen is scanned.

Flatbed/ADF

This option is shown if either the Automatic Document Feeder [ADF] or Reversible Auto Document Feeder [RADF] are fitted to the connected e-STUDIO MFP.

When selected pages in the document feeder will be scanned (single sided, even if the RADF is installed). If no pages are present in the document feeder then the page on the MFP’s flatbed/platen is scanned.

RADF

This option is shown if the Reversible Auto Document Feeder [RADF] is fitted to the connected e-STUDIO MFP.

When selected, pages in the document feeder will be scanned doubled sided. Insert pages into the scanner top edge first.

Scanning Multiple pages

Some versions of the XSANE and Kooka scanning applications can only scan one page at a time. When using such a version, click the Scan button quickly after a page is scanned to retrieve the next page and continue this process until all scanned pages are retrieved. If you do not click the Scan button again, or you close the scanning application, all remaining pages in the ADF/RADF will be discarded.

When retrieving multiple pages by repeatedly clicking the Scan button any changes made to the contrast, resolution, image type or any other scan settings made after the Scan button is first clicked to start the scan process are ignored.

If more than 5 seconds elapse between the MFP SANE scanner driver passing a page’s image data to the Linux application (e.g. xsane or GIMP) and the driver receiving the request to scan again then the new scan is treated as a new job rather than as a continuation of the previous job. As such, it may be scanned from an alternate source. This can happen with slow computers that take more than 5 seconds to process each page.

Later versions of the XSANE provide a Pages option that can be used to specify the number of pages to be scanned when the Scan button is clicked once. If there are more pages (or sides, when scanning using the RADF source option) in the document feeder than are requested via the Pages option then any excess pages/sides are discarded.

Be aware that some applications can only scan single pages at a time.

Contrast

The e-STUDIO SANE scanner driver provides 7 contrast settings varying from 0 (lightest) to 6 (darkest) with the default being 3.

Scanning with Kooka 

Some versions of Kooka do not support A3 paper size and as a result when using these versions of Kooka with the e‑STUDIO SANE scanner driver the page size selection will not work properly.

For best results always do a preview scan, and then select a rectangle on the previewed image to define the area that is to be scanned in detail.

Alternatively, when scanning A3/A4, select the next smaller paper size to the size you want to scan.

i.e. to scan A4 select A5, to scan A3 select A4.

Scanning using xscanimage (from GIMP) on NLD/SLED9 

If an error occurs while scanning or initialising the scan link the xscanimage application, which is used by GIMP to scan images, does not re‑enable the Scan button. If this happens, close xscanimage and reopen it from GIMP. Any preview done in xscanimage will be remembered when xscanimage is restarted from the same session of GIMP.
