Need to get the firmware to load onto a USB drive for a C5540i III. Had to replace a bad hard drive.

Hello!

You'll need to contact your Canon Dealer. They take care of support for this unit. Their contact information should be on the machine—usually on the front or side panel. If you don't have a Canon Dealer and you're not under a service contract, call 1-800-OK-CANON (800-652-2666), and one of our agents will help you find someone local who can help!
