How can an ordinary canon pixma mp258 printer and scanner scan 35 mm film negatives?

You will need to check your Canon software that came with your Pixma MX310. I have a stand alone Canon Canoscan 8800F scanner that have the capability to scan 35mm film strip and 35mm mounted slide, the software included the feature for it.

When you were scanning, did you set the scan selection to scan negatives ?

I have had that problem with the MX310.
depending on what IOS you are running
you can get software free that will scan
Transparencies "opposite"

change the usb port or conform whether device are countering each other?

You cannot scan negatives or slides with this all in one printer.
You need a film scanner.

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.

ho to use the scanner of canon mp258

I inserted my negative holder in backwards on my Nikon 5000 35 mm scanner. Then I could get the last (5th) slide scanned. But I can not get the scanner to work on my new IMac because of no working driver. Silver Fast has no drivers for the Nikon 5000

Try putting a strip of negatives into the loader. That should solve the problem.

You should be able to do about 12 at a time using the 35mm film strip film guide. What Kind of trouble are you having?
