There will be one of several micro switches that detect when various doors hatches and flaps are open or closed. These are usually recessed behind small slots in the casing. Each will have a corresponding spike or flange on the appropriate door hatch etc. carefully examine each of the movable pieces and look for evidence of a small piece that may have broken off or a "socket" that does not have a "plug" to fill it. Test these by carefully feeding a non-conductive probe (just in case) into the port and feeling for a little bit of springy resistance. If you find one, fold some light card into a tube that fits snugly into the hole and depresses the switch. Close everything up and try the machine. Hopefully you will find the missing link, then it is just a matter of making a semi permanent plug that you can remove when you need to.

51.23 Error - Yellow laser scanner error
Turn off the power by using the power
switch, wait at least 30 seconds, and then
turn on the power and wait for the printer to
initialize.
If a surge protector is being used, remove
it. Plug the printer directly into the wall
socket. Use the power switch to turn the
printer on.
If the error persists, contact HP Customer
Care. See HP Customer Care or the
support flyer that came in the printer box.

I am trying to scan, but when I press the scan button it states "No scan options. Refer to device doc to troubleshoot". However, I can't find my device doc. I am assuming there is an easy fix?
SOURCE: I've got message 0x61011be6 -
I assume that you have tried to reset it:
-press the print photos and red eye removal button together
-once doing that on the little screen on the printer it should be asking to enter special key combo
-enter "red eye removal, print photos, red eye removal"
-after that it should be on SUPPORT menu
-press the right arrow and go to resets menu
-press ok
-go to partial reset
-press ok
-the machine will turn off by itself
-just turn it back on after 1 minute
and it didn't work.
in that case the processor of the printer is no longer capable of generating the format of the final image for the cd - hardware failure. The only way to fix it would be to replace the mainboard but this costs more than a new unit so it will be cheaper just to buy a new one.
