There must be a problem with the output sensor, dirty, bent or clogged. Check all the paper paths and if possible reset the error code. Regards, Mike

1. The output bin may be full. Empty the output bin. Printing resumes automatically.
2. Take a close look at the flaps hanging out the exit of the printer. They should move up and down freely. If one of them is stuck up, broken or dislodged, then a bin full error is displayed.
3. Open rear exit tray and power on the printer. If the printer comes to a Ready state, close rear tray and try printing.
4. Clean the paper path below the toner area and exit assembly at the back of the printer. Ensure there is no pieces of paper stuck in the paper path of the 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.

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.

Hi, Remove all the papers from out put bin & check if not solved remove both side and top covers absorve right side of the out put bin flag sensor clean it with high pressure air or clean with dry cloth gently. Best of luck...Vinay

out put bin is full

check output bin sensor

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