My HP 8620 Printer won't let me physically install the cartridges.

[BensMom1]

I tried using off-brand cartridges when the HP ones needed replacement. The printer wouldn't recognize them. I removed them and wanted to re-insert the original HP ones. But they simply won't insert into the carriage. They go in part way and then won't go any further. The same thing happens when I try to re-insert the off-brand ones.

Hi @BensMom1,

I'd like to help!

Let's try a power reset on the printer to resolve the issue-

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.
• Check if there is anything blocking the ink cartridges.

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware

You may refer to the document on how to insert ink cartridges-Replace HP inkjet printer cartridges

Hope this helps! Keep me posted.
