How to reattached output bin cable - HP LaserJet M4345 MultiFunction Printer

Probably just a bad sensor or dirty sensor causing the issue.

Stacker or stacker/stapler output bins

For the 3,000-sheet stacker or 3,000-sheet stacker/stapler, the output bins are the upper bin (face-up) and the lower bin (face-down).

The upper bin (face-up) is the top bin on the stacker or stacker/stapler. This bin holds up to 100 sheets of paper in face-up order as they exit the printer. A sensor causes the product to stop when the bin is full. Product operation continues when you empty or reduce the amount of paper in the bin.

Lower bin (face-down) is the lower bin on the stacker or stacker/stapler. This bin holds up to 500 sheets of paper and can stack or staple jobs. This bin is the default output bin.

Power off your printer. Take out the papers and unplugged cables from it. Remove the cartridge and then check is anything jamming the paper inside.
After checking, reinsert the cartridge and plug the cables. Keep the paper and take a test print.

As the output bin accumulates
paper, the output bin delivery flap
rises until a flag blocks the
photosensor (PS911). When the
photosensor is blocked, this
message appears.
Rotate the output bin
delivery flap up and down.
The flap must move freely. If
the top cover has been
replaced, make sure that it
has been installed correctly.

Place the bin on top of the filter housing, with the bin tilted slightly away from the vacuum, then while the bin pressing down and towards the vacuum keep pressing until you hear it 'click' onto the latch. Sometimes it helps to lift up the latch while you are installing the bin and then let go of the latch once the bin is installed.

HP says: 1) remove all printed pages from output bin 2) "flick" the output bin lever with your finger
If fault continues, contact HP.

Look for the sensor that is tripped when the output bin is attached. Trace the wiring back to origination. Either sensor is bad or wiring is bad.

my experience says jamming in duplex area using card stock. this may occur if default is duplexing. set default to single side and / or try same job using plain a4 80gm2

You say you have opened and closed the cover, your error appears to be related to the output bin assy on the left of the printer. Remove and reininstall the output bin assy.

I think you need to be aware, that if you don't have a good enough soldering iron, magnifier, jig, or enough copper, solder and laquer to do this job properly,.. It belongs in a bin:(
Sorry to say it, but, throw it away.
If the 'motherboard' in your computer, was cracked or smashed,.. Then you arrive at the local computer shop, show it to the guy behind the counter, who will say, "It's **** son."
Or words to that effect.
Simply because, in the long term, it will not be a cost effective affair.
Just buy new. That's what they ALL want you to do in the end.
Some things just go in the bin. Sorry,..
I'm glad we got that cleared up:)

I used the Optra W810 driver. It had listing for *UPPER and *LOWER for the bins....

So..I took a chance on the following


Output Bin
Sel Cmd Description
1 3 Output Bin 1
2 4 Output Bin 2
*LOWER 2 Lower Output Bin
*UPPER 1 Upper Output Bin
3 5 Output Bin 3

All is goo!
