- Ensure that paper trays are loaded properly,
- Check the input area for obstructions.
- Remove the print cartridge and check for paper in the paper path.
- Ensure that paper is feeding correctly from the appropriate tray (try using a freshly opened ream of paper).
- Inspect the pickup assembly by removing the paper tray.
- Locate the rubber roller with a purple, plastic hub (paper feed roller).
- Locate the paper pickup assembly that is directly behind the paper feed roller..
- Rotate the shaft to locate the half-moon rollers and ensure that it turns easily.
- Locate the black plastic coupler shaped like a dog bone that is immediately to the right of the shaft .
- If either the pickup assembly or the coupler is missing or damaged, the printer will need to be serviced.
- Do not fan paper to separate, bend the ream into a U shape to break the sheets free from one another.

| 49.x SERVICE ERROR |
Communication related issues
The codes following the 49. can vary widely. For example, they could appear as 49.4C03 SERVICE ERROR |
The first step with any printer troubleshooting is to isolate the printer from the network and any software applications that may be causing the problem.
The reason for testing the printer in this "stand alone" mode is to verify it is working properly.
To test the printer in "standalone" mode, perform the following:
• Turn the printer off and unplug any parallel cable from the printer.
• Unplug the network cable (if applicable) from the HP Jet-direct card (if equipped) and then remove the card from the formatter.
Power on the printer. After the printer reaches a Ready status, print the following test pages: Configuration page or Self Test page (list of installed options), Event Log (list of most recent printer events to aid with troubleshooting), Menu Map

5 = Inconsistent Fuser |
Turn the printer off, wait 20 minutes, and then turn on the printer.
Eliminate any contributing factors by performing the following steps:
• Remove the printer from any UPS (Uninterruptible power supply) devices.
• Remove the printer from any additional power supplies or power strips.
• Plug the printer directly into a wall outlet.
• If the printer is already plugged into a wall outlet, try another power source in the building that is independent from the one currently being used.
• The line voltage and current source at the printer location may need to be inspected to ensure that it meets the printer's electrical specifications.
• Reseat the fusing assembly.
• Replace the fuser. The 50.4 error message is usually related to an issue with the line voltage going into the printer.
