Hello!

Officejet Pro 8600 displays message about "Remove the rear access panel or automatic 2 sided printing accessory . . . " when  I try to print, even though there is no paper jam. I've done the troubleshooting: unplug, etc., watch the HP videos, remove the back, remove the head from the carriage, etc.   Any help, anyone? Thanks in advance.

Found the Fix!

Robert Backhaus previously has posted a fix to this problem titled "Fix False Paper Jam." Following his directions partially posted below, I worked the lever at the far right back inside the printer. Worked it back and forth. The lever is attached to a small spring that apparently gets old or stuck or breaks or all three. Regardless, my 8600 is now printing like an old pro. If I have the problem again, I'll just jiggle the spring again. When that doesn't work, I'll replace it, per Mr. Backhaus directions, all of which I have not included but are available on the Internet. Here's the excerpt from Robert's helpful post: 

• the symptoms of this fault are:

  The printer displays a 'Paper Jam' error, and tells you to remove the rear duplexer, and says that you may need to open the front cover too. When you touch 'OK', nothing happens, unless you open and close the front door.

• When you open and close the front door and then touch 'OK', the printer mechanism moves a little and then it displays the error again. Occasionally the printer may move through most of a full initialization before stopping again.

• If you bypass the door close mechanism (place an opaque object in the rectangular slot on the left hand side), you will see that the paper feed rollers are moving a small distance back, the carriage moves to the left slightly, then the feed rollers move forward and stop.

• Shine a light into the printer, and check over on the far right for a small lever. This lever should slide to the right with gentle pressure, and spring back into position. If it doesn't slide back, try pulling it gently to the left.

• If you can move the lever back and forth but it doesn't spring, then you need to disassemble your printer and replace this spring.
