5B00: Canon ink cartridges that use a 5B00 error code have reached the end of their lifespan and will need to be replaced. You can reset the error code by pressing and holding the “Stop/Reset” button on the printer for ten seconds. This should reset the counter and allow you to continue printing.
700: Canon ink cartridges that display a 700 error code indicate that the cartridge is not installed properly or is not recognized by the printer. Check to make sure the ink cartridge is correctly installed and is compatible with your printer. If the problem persists, you may need to remove and reinsert the cartridge several times until the printer recognizes it.
