The printer displays "data communication error". Looking closer I noticed the small green circuit board near the color indicator on the cartridge is missing! Canon Quality Control missed this one. I called the customer line and they said there is only a 30 day warranty and I must have a receipt. I bought this a few months ago and no longer have a receipt. This is a brand new but unusable product! A 30 day warranty is a joke. I prefer to buy cartridges well in advance so I have them when I need them. Canon should send me a return shipping label, so I can return this for a replacement.&nbsp;&nbsp;</P> Tue, 29 Apr 2025 12:12:58 GMT gregrock 2025-04-29T12:12:58Z https://community.usa.canon.com/t5/Office-Printers/imageCLASS-MF644Cdw-bad-Canon-cartridge/m-p/546711#M26480 <P>I just installed a new 054H Magenta cartridge in my Imageclass MF644cdw printer.
