And given you can't really see into those cartridges - I think I would not be surprised that is not the case.
I dumped my not quite 2 year old OfficeJet in 2012 - for repeated error codes no matter how many OEM new cartridges I stuck in there. In the end... >$100 in unused cartridges.
Happily using Epson since then... so 11 years of use and no repairs needed. Does what I need (rarely print, but need it when I need it).
