Chips, Printer Messages & Installation

Installing: open the front door and pull out the toner drawer. Lift out the empty cartridge, rock the new one gently five or six times to spread the toner, remove the protective cover and sealing tape, set it into the matching color slot, push the drawer in and close the door.

Messages: the printer may say a non-Canon cartridge is installed or that the remaining toner can't be shown. Confirm the message to keep printing. If a cartridge isn't recognized, take it out, check that all packing material is off and reseat it firmly. See our guide to fixing a cartridge that isn't recognized.

Streaks or faint print: rock the cartridge again and run the cleaning routine from the printer menu. See laser printer streaks and lines.

Quality: Compatible, Newly Manufactured

This is compatible toner: newly manufactured by a third party to the original's size, chip and page-yield specifications and tested before shipping. It is not a refilled original. Castle Ink sells compatible (newly manufactured) toner and drums, and remanufactured inkjet cartridges.

Frequently Asked Questions

How many pages does the Canon 045H print?

About 2,800 pages for black and about 2,200 pages for each color, or about 9,400 pages for the full 4-pack, based on Canon's ISO/IEC 19798 ratings at roughly 5% coverage.

What is the difference between 045 and 045H?

Only the yield. Standard 045 is rated at about 1,400 black / 1,300 color pages; 045H at about 2,800 / 2,200. Both fit the same printers and can be mixed.

Does 045H fit the MF642Cdw or MF644Cdw?

No. Those use Canon 054. Canon 045 fits only the models listed above.

Can I replace one color at a time?

Yes. Each color is a separate cartridge, and singles are listed above.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party supply. If a non-original supply directly caused damage, that specific repair might not be covered.
