Where can I return defective laser jet cartridge - CF401A

[PeterD9]

I purchased a laser jet cyan cartridge.  shortly after installing I started to get wavy blue lines on the edges of printouts.  Since I print mostly black and white I wasn't too bothered.  In addition, this is a light usage home printer.   Finally I sought help thru this support community and was told that the cause of wavy lines was a defective cyan laser jet cartridge.  I replaced the cyan cartridge with a new one and it did solve the problem!  I was relieved thinking the problem might have been the printer itself.  The defective cyan cartridge is still 60% full.  I took it back to Office Max to get a refund (same place I buy all my HP supplies) and they refused saying it was purchase more than a year prior.  I'm writing here to see if I can get compensated for this defective cartridge directly from HP?  If so, what is the process?  I have the cartridge, receipts and printed examples of the problem before and solved after a new cyan cartridge was installed.  Thank you.

HP's stated warranty is until cartridge is at "very low". You need to contact HP technical support directly at [edit] in order to create a case and likely they will replace the cartridge not refund it.\
