iPF770 Ink Level Detection Cause Head Cleaning B in the Control Panel menu is executed frequently. You have just finished initial installation, when more ink is consumed to fill the system. The Printhead nozzles are clogged. Corrective Action Head Cleaning B in the Control Panel menu consumes a lot of ink. This does not indicate a problem with the printer. Unless the printer has been moved or stored for a long period or you are troubleshooting Printhead problems, we recommend not performing Head Cleaning B, to the extent possible. After initial installation or at the first-time use after transfer, ink flows into the system between the Ink Tank and Printhead. Although the amount of remaining ink may drop as a result, it does not indicate a problem. Check for nozzle clogging. (See "Checking for Nozzle Clogging.") ➔P.502 Ink Level Detection Ink level detection will be deactivated if you load ink tanks once emptied. Ink level detection Ink tanks specified for this printer feature an ink level detection function to prevent the ink from running out during printing, which prevents printer damage. (See "Ink Tanks.") ➔P.496 This function will not work correctly if you use refill ink tanks. As a result, printing stops. Thus, before using refill ink tanks, you must cancel the ink level detection. Printing with the ink level detection canceled may lead to printer damage and printing problems. Canon Inc. is not liable for any damage that may occur as a result of refilling ink. • After ink level detection has been released, this function cannot be reactivated for currently loaded Ink Tank. To Important use ink level detection again, replace the Ink Tank with new ones specified for use with the printer. • Repeatedly removing and inserting an Ink Tank may damage the connection between the Ink Tank and the print- er, which may cause ink leakage from the Ink Tank and damage the printer.
