Error message ox61000020 on HP OfficeJet Pro 8710

My HP OfficeJet Pro 8710 suddenly started having paper jam and roller turning issues. Error message Ox61000020 comes up on printer display. Virtual assistant told me this message means the printer needs a service and I need to speak to agent online. When I try to do this a message comes up that they're unable to help at this time

     The printer carriage has jammed and I have traced the failure to a broken plastic gear assembly. It is responsible for moving the absorbant pads under the carriage assy. By not installing it at all, I discovered it also moves the paper during the printing process. I have forwarded a picture of the gear assy to HP and they don't think that it is a user replaceable part. I have contacted a distributor in Texas and they also said it is not a user replaceable part. HP Tech Support is worthless. I hate to throw the printer in the trash for a simple plastic part.

     If you are interested, I am including some utube posts which show how to dissassemble the printer.

Thank you so much for your reply. In fact it turned out that in my printer's case, all I needed to do was clean the printhead and do an alignment! It's a pity the error message didn't link to this advice in any way when i first did Virtual Assistant. It got there in the end though. All fine now. Sorry you had so much trouble with your printer
