Printer Repair Questions? Ask IT Technicians for Answers ASAP
If the scanned negatives are showing up as a series of fine coloured dots, then check all the settings and ensure nothing has changed. Also check for dust inside the scanner - use an air compressor to blow it out.
Test the scanner on a different computer.
If the problem persists then the scanner has a fault and will require a repair or replacement.
Glad to hear you got it sorted!
Have a great day,
