OfficeJetPro9710-HP instant ink and reg ink 952 will not insert all the way

[Robertpaul13400]

I have had an Officejet 8710 Pro all in one printer trouble free for years using HP 952 ink --not the cheap ink-the HP ink. . I just registered with Instant Ink and when the 1st shipment arrived I inserted the cartridges and found the Yellow was 3/4 empty. I called and asked for a replacement and when trying to print,  the message asked me to check the cartridges to see they were seated correctly. I took them all out and now cannot insert all 4 of them all the way in, including my 4 original non instant ink HP cartridges. They go in about 2/3 and then get stuck. I unplugged  my printer for 1 minutes to no effect and made sure that webservices were connected (they are) and that the firmware and all software are up to date (it is). What can I do to fix this issue. There is no paper jam and each of  the cartridges seem to get stuck when they are about 2/3 in.

@Robertpaul13400, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

In the OfficeJet 8710, each ink slot has a spring-loaded mechanism.

If you removed a cartridge while the printer was off or jammed one in mid-cycle, the cartridge latches may have locked.

Power off the printer.

Open the ink access door and gently press each latch (where the top of the cartridge would normally lock in).

They should flex slightly. If any feel stuck, carefully try to realign or nudge them forward using the blunt end of a pen or similar non-sharp tool.

Then, try inserting the cartridges again with firm, even pressure until they click.

Test With One Cartridge at a Time

Instead of inserting all four cartridges at once, try:

Insert Black cartridge only, power on printer.

If accepted, insert Cyan next. Continue in sequence.

This helps detect if one defective cartridge or slot is causing the blockage.

Try Your Original Cartridges Again

If the Instant Ink cartridges aren’t seating, go back to your non-Instant Ink HP 952s.

If even those won’t go in, it confirms a mechanical jam in the slot — not a cartridge issue.

Hard Reset the Printer

Unplug the printer with the cartridges removed.

Hold the Power button for 30 seconds to drain residual charge.

Plug it back in, let it sit idle for 2 minutes, then try reinserting the cartridges.

I hope this helps.
