LJ M2727 - Change default size for scans from ADF?

[UrNerd]

The default output size for scans from the document feeder (as shown at bottom of TWAIN dialog) is 8.5x14", so that's the scan I get every time (with 3" blank space at the bottom) when I feed in letter-size paper.  All the paper-size defaults I can find are set to Letter.  Where is the option to change the default input/output size for scanning?  I can't find it anywhere in the HP software, and it's too tedious to correct scans by hand one page at a time.

It's nice to know larger sizes can be scanned, but why can't it just tell what the actual paper size is?  I know the M2727 is an old printer, but otherwise we love it.  Thanks!

Hmm, no help...

For what it's worth, I've come to suspect that this is not a user setting, rather the ADF is meant to detect the paper size being scanned and is simply failing to, due to a faulty sensing mechanism.  I'll have to consider whether it's worthwhile to get fixed, if parts are even still available.

I finally found the problem.  The ADF is meant to sense the source paper size.  While exploring the paper path to see where the sensor could be, I found a sliver of some blue shiny material stuck at the edge of the mechanism.  So small it's hard to believe that's all it was, but once removed the ADF automatically scans to the appropriate size.  I hope this tip helps someone else.
