There is a big problem with HP inkjets with separate printheads, and people are throwing these away in large numbers.
I live in a city with 100k inhabitants and every week a couple of HP OJs 6xxx - 8xxx are joining the pile on just a single WEEE collection point, almost all with printhead problems. Especially, but not limited to, 920 / 932-933 and 950-951 printheads.
Soft resetting and reseating (even 3 times to clear the error message), cleaning, checking the contacts on the printhead circuit board, connectors or flex cables, even upgrading FW may work sometimes. But on most cases the printhead is just busted no matter that the PH board components look of high quality and test fine.
I have 11 printers some unlucky owners couldn't, or didn't afford to fix - all with original/expensive cartridges, some full on ink.. Can't say if these people had to buy new HP replacements (or other brands), but this is obviously planned obsolescence.
Has HP expanded its profit margin on replacement printheads, since they lost their fight with cartridge remanufacturing companies? The prices may confirm. I did not hear yet of a remanufacturer making a printhead of their own, only recycled units sold online by small entrepreneurs (which may not even bother to test).
What's your experience on this subject?
