Since the scanner is not compatible with your OS, you can also try using the VueScan software that the Hamrick Corporation offers to see if it will allow you to use this scanner with Catalina. This software does not require a driver. The Hamrick Corporation does have free software that you can test with your scanner. If you do want to visit their website, the address is www.hamrick.com. If you need support for this software, you can visit www.hamrick.com/support/.
You would also qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.
If you would like to take advantage of this offer, please the Canon Sales Department at (866) 443-8002 Mon-Sat, 9 AM to 9pm EST excluding holidays.
