I just bought a set of 045 canon printer cartridges all read 90% except black which is at 40%.

Hello. If the toner was purchased from Canon directly, please see https://canon.us/returns

If it was purchased elsewhere, you'll need to contact the reseller where it was purchased to go over your options.

If you feel like your unit might be malfunctioning, or misreading the toner, contact support. They're at 1-800-OK-CANON (800-652-2666), Monday through Friday from 8am to 8pm (ET).
