These replacement cartridges are literally 1/5 the price of HP branded cartridges. Cyan (there are four) was rated "low" and then "very low" compared to the original (lasted 18 months - 1300 page yield for home use with three kids at school - not bad), but this cartridge costs Β£98 $ from Revain or Office. Depot. At Lemero, you can get all four colors for less than $70. I followed the instructions both inside the printer (lift the blue handle after opening the front door) and removed the cyan (cyan) cartridge. The new cartridges are not packaged with any markings, so you must look carefully through the yellow translucent cyan packaging. Carefully remove the protective packaging and carefully insert it in the same direction you removed it. Lock the blue handle and close the door. You are ready to print. Printed from six full-page photos, so far so good.
