We have boxes of old slides that are not 35mm I would like to convert to digital. Will the small digital slide/negative scanners accomodate them? If I remember correctly, they were smaller than the common ones, and required a specific slide projector to show them. I was looking at the ScanPro scanners.

There may be a setting in the software to enable you to correct this - if not, then you'll have to deal with it in post-processing.

When you go to scan your slides, the software should have a setting for "slides", or "negatives". Make sure you select the correct one for what you've put in.

I can't find a manual online, but I'm sure it is in the manual that came with the scanner.

Firstly remove your scanner what you have now. Then restart your computer. Now install your scanner driver and also restart your computer. Now try it. I hope it will be fine now.

This multi function printer/scanner cannot scan 35mm slides and negatives.
Some flat bed scanners with a lighr scource that shines through 35 mm slides and negatives can scan them.
You will be better off getting a dedicated 35 mm slide/negative scanner.
Check out this WEB site foe slide scanners.

A search for that model on Brookstone's website takes me to the iConvert Instant Slide and Negative Scanner. That scanner does not require an installation CD. It works by scanning slides or negatives and then saving them to an SD card. Many digital cameras use SD cards so you may have one already. Otherwise an SD card will need to be purchased separately.

you have chosen normal preview
1. change it to thumbnail preview
2. or click on "All" button in normal preview
so you would scan multiple negatives.

increase your dpi setting or your target area or both
I am also scanning color negatives at 3600dpi and 48bit. file is large but quality is very very good...

check settings in dpi..

First option would be the manufacturer, second would be EBAY for either the part, or a used unit with the part.
