OfficeJet 8600 copy fails with "paper detected does not match"

[paperwrangler]

I've developed the problem with my OfficeJet Pro 8600 Plus, where I get the Paper detected doesn't match...message.  Only copying is affected; printing and scanning are fine. 

I've tried the various suggestions re unplugging etc., checking for firmware updates, etc. that I've read in the forum; it looks like I need to do reset.

Can you please provide directions for doing so?  I will not republish.

Thanks

I'll be glad to help you 🙂 

As I understand the printer doesn't work due to the error message - Paper mismatch,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

As mentioned, I have the problem ONLY for the copy function, not for printing, which is fine.  The suggestions on other threads that might pertain to copy I tried before posting, as mentioned.  (Multiple times, and with prolonged power disconnect once).

The thing I cannot do without instructions is the reset.  I am requesting reset instructions (NOT updating firmware, which I already double checked).  It says user must agree not to republish those, so I agreed to that in my original post, and further agree here.

So, looking specifically for reset instructions.

Thank you.
