C1765NFW, paper jam error 177-900

Question

My printer, which of course just came out of warranty, is giving me an error 007-900

I already looked, and there is no paper back there

I did, of course, a search on the forum, and found this

I tried holding the AC button, but nothing happens

Any other ideas?

I'm having the same exact problem, but with a '077-901' error code. AC button didn't work for me either. I'm going shopping for an HP tomorrow if I can't get this fixed in the next couple hours.

AC button has no effect. (I've timed 15 seconds.)

I found posts (more helpful and less helpful), contacted support, and scrutinized the User Manual. Based on other community posts by @llynster and @Dell- Praveen (apparently no longer listed) I want to find out where the various sensors are, and I want to find out how to manually actuate the rollers. A Service manual would be wonderful! Pictures of what parts I need to disassemble would be good.

I can get it to come up with the "Ready to Copy" message.

I can bring it up in Customer Mode and display Digital Input
