HP LaserJet M17w Pro

The basic printer functions should start up when the printer is connected into an electrical outlet and the power switch is pushed to the on position. If the printer does not start, use the information in this section to isolate and solve the problem. MFP M28-M31 wireless model only: If the control panel display remains blank, random patterns display, or asterisks remain on the control panel display, perform power-on checks to find the cause of the problem.

Test pages

Printing a test page helps determine if the printer is functioning. If a printer failure occurs, print a test page to verify printer functionality.

Engine-test page

With the printer on and in the Ready state, open and then close the cartridge door four times within 5 seconds. The printer prints one simplex engine test page.

Troubleshooting power on problems

1. Verify that power is available to the printer. If the printer is plugged into a surge protector or uninterruptible power supply (UPS), remove it, and then plug the printer directly into a known operating wall receptacle (make sure that the wall receptacle provides the correct voltage and current for the printer). Unplug any other devices on the same circuit that the printer is using.
2. Try another known operating wall receptacle and a different power cord.
3. Listen for startup noises (motors and output roller rotation) and illuminated lights on the control panel. If startup noises are not heard, try opening and then closing the cartridge door.
   NOTE: Operational motors and control-panel lights indicate the following:
   • AC power is present at the printer.
   • The low-voltage power supply (LVPS) is providing either or both 24 Vdc and 5 Vdc voltages.
   • The DC controller microprocessor is functioning.
4. If startup noises are not heard, check the following:
   a. Turn the printer off, and then replace the formatter (the engine can not turn on with the formatter removed).
   b. Turn the printer on, and then listen for startup noises. If normal startup noises are heard, go to step 5.
   NOTE: MFP: M28-M31 wireless model only: The control panel will be blank with the formatter removed.
   c. If normal startup noises and lights are still not present, replace the engine controller assembly.
   NOTE: If the error persists after replacing these assemblies, escalate the problem to the Global Business Unit (GBU).
5. Try printing an engine test page.
   NOTE: The test page can only use the cassette tray as the paper source, so make sure that paper is loaded in the cassette tray.
   • With the printer on and in the Ready state, open and then close the cartridge door four times within 5 seconds. The printer prints one simplex engine test page.
   If the engine test page prints, the print engine is operating normally (a failed engine test print page does not necessarily indicate that the print engine or DC controller is defective).
   NOTE: If the engine test page does not print, turn the printer off, replace the formatter, and then try the engine test again. If the page prints, the problem might be the formatter.
