Along time ago, I had a Lexmark printer that required small cartridges which had to be replaced at $50.00 or more each. My Cannon Printer using the 137 Black toner lasts for months of moderate use or for many weeks of heavy use such as printing a book of 40 pages per copy. This is a significant saving.

Works very well. Clean,crisp and consistent printing, even on pages with extensive toner coverage such as pictures and dark backgrounds. Cartridge is properly recognized by the printer. These are an excellent value. We will be buying these again.

Yep

works as expected, would buy again
