20 Most Recent HP LaserJet 8150n Printer Questions & Answers


By left side I assume you mean the fuser side. There are tabs on the left door that activate optical sensors in the printer body. Best option is to find a copy of the manual so you can see where the sensors are and either find a way to fix the door or jimmy the sensors. Please keep in mind that most of these sensors not only ensure that the doors and panels are closed, but shut down power to those sections to make it safe when printer is open.

62.0 memory error. This error indicates that the memory that is soldered to the formatter is likely bad. If the error was 62.1 or 62.2 that would indicate that the memory in one of the upgrade slots was bad. The only real solution to 62.0 will be to replace the formatter.

If the printer isn't intializing then you may have a formatter issue. Try reseating the the formatter in the back of the printer. There is two thumb screws that hold it in place. If the printer is booting up and you can still print to it but you just can't read the control panel then the problem is with the control panel.

Hello,

The 50.1 error is caused by the fuser assembly not getting hot. The part you need is called a maintenance kit, it comes with the fuser and all of the pickup rollers needed to keep the printer in good shape. We have the kits available for $125 plus shipping. You can contact us at 318-447-9040 or at tech@ccl-la.com if you need to place an order. The kit will also include a PDF version of the service manual for this printer.

I hope this helps, if so please rate our solution.

CAUSE: This error message indicates the paper present sensor flag in one of the trays does not detect paper in the tray. This could be caused by one of the following:
  • A broken sensor flag
  • The tray paper guides being set too close and restricting the paper from being pulled
  • The tray is not lifting
SOLUTION: Follow the steps below to determine the cause of a false TRAY X EMPTY message. Tray 2 empty
  1. Verify there is paper in the tray.
  2. Open the duplex unit access door just above Tray 2 on the front of the printer.
  3. Check the black-paper present flag by looking in through the duplex access door.
  4. Open and close Tray 2 and observe the tray lifting looking through the duplex unit access door.
The tray lifts but the error is still present
  1. Inspect the paper present flag on the PIU located just behind the pickup rollers. Ensure the flags are present and not damaged.
  2. Remove the tray guides from the tray and reseat them. Ensure the guides are seated correctly and are in the correct slot for the size paper in the tray. Add paper to the tray and try printing again.
  3. Try another known good tray, if available.
The tray does not lift and the error is still present
  1. Remove the tray, remove the paper in the tray, and inspect the lifting plate in the tray for damage. Ensure it will lift freely by hand.
  2. Try another known good tray if available.
Tray 3 empty
  1. Verify there is paper in the tray.
  2. Remove Tray 2.
  3. Open and close Tray 3 and verify it lifts by observing through the Tray 2 cavity.
The tray lifts but the error is still present
  1. Inspect the paper present flag on the PIU located just behind the pickup rollers. Ensure the flags are present and not damaged.
  2. Remove the tray guides from the tray and reseat them. Ensure the guides are seated correctly and are in the correct slot for the size paper in the tray. Add paper to the tray and try printing again.
  3. Try another known good tray if available.
The tray does not lift and the error is still present
  1. Remove the tray, remove the paper in the tray, and inspect the lifting plate in the tray for damage. Ensure it will lift freely by hand.
  2. Try another known good tray if available.
Tray 4 empty
  1. Verify there is paper in the tray
  2. Open Tray 4 and check for an extra **** of paper stored on the left side of the tray. This can cause the tray to stall while lifting and result in a tray empty message.
  3. Defeat the interlock in the vertical transfer unit (VTU). Open and close Tray 4 and watch the tray lift through the VTU door on the lower-right side of the printer.
    NOTE: Follow troubleshooting steps for Trays 2 and 3 when working with the 2 X 500 sheet-input tray.
The tray lifts but the error is still present
  1. Check the tray guides to ensure the guides are seated corrected and are in the correct slots for the paper size in the tray.
  2. Inspect the paper present sensor for damage.
  3. Check for any broken plastic pieces in the tray that may be a broken sensor flag.
The tray does not lift and the error is still present Defeat the VTU interlock on the right side of Tray 4. Open and close Tray 4 and observe the tray lifting.
