Question about HP Officejet J5780 All-In-One InkJet Printer
If the new (or
refilled/reman/compatible) HP 74, 75, 74XL, or 75XL ink cartridge refuses to
complete the printer alignment following cartridge installation, then the ink
cartridge either has a connectivity issue with the flexible printed circuit
cable (inside unit where cartridge mates with cable), rear cartridge contacts
or cable contacts are dirty with ink residue, or the cartridge is suffering
from marginal internal electrical performance.
These types of severe cartridge errors (i.e. refer to documentation / incompatible cartridges, print cartridge(s) problem, etc.) typically indicate the internal micro electronics of the HP 74/75 cartridge are damaged. The cartridges electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal micro electronics failure.
I suggest you first run a Tap 41 diagnostic test to check cartridges electrical health (this is a special forced service test; refer to Inkjet411 videos so you understand how to activate and read the HP OJ printer diagnostics print out).

Try cleaning with a wet towel the contacts in your printer
probably have ink on contacts and nan not read your cartridges
it is the metal pins ,the point that cartridges are getting in
