Envy 5660, trying to print #10 envelopes. "Paper Size Mismatch".
Product: Envy 5660
Operating System: Microsoft Windows 10 (64-bit)
Trying to print #10 envelopes. Setup printer options, regarding paper size, which try, etc. Created an envelope, using Word 2016, setup printer options in Word to match printer options on the device itself. When I press the print button, I get the message, "Paper size mismatch" on the printer display. I have tried all options suggested by HP diagnostic program, and users who have received the same message. I have updated drivers, disconnected and unplugged printer, etc. on and on, nothing has worked. I suspect that the printer sensor is not working correctly, since all other options seem to have been exhausted. Any further ideas?
