How can I scan a whole stack of pages into a single .pdf file

The Avision AV220 scanner in the basement lab is ideal for this task. Assuming that your document is monochrome and contains writing on no more than two sides of each page, then you can simply:

1. verify that the Avision AV220 is turned on

2. Get a shell on census (unless the Avision AV220 is connected to a different machine). To get a shell either logon to census or ssh to census from another machine.

3. Run scan2pdf. scan2pdf is a locally written program that calls several other programs which: (1) scans your document, (2) convert each page to postscript, (3) converts the postscript into a single .pdf file, and (4) deletes all the intermediate junk.

So, once you have a shell on census just type:

@:$>$ scan2pdf -o document.pdf

where document.pdf is the name of the pdf file that you would like to create from the scanned images. scan2pdf will prompt you as to whether you like 1 or 2 sided scanning.
