Printer power problem HP 4652

[Sowulo_1111]

My HP Officejet 4652 printer got unplugged without being turned off and now I can't get to turn back on.

When I plug it in the screen will flash once and go black again.

@Sowulo_1111, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
When an HP OfficeJet 4652 printer is unplugged abruptly and won’t power back on—only flashing the screen once—this usually indicates a power-related issue, either with the power supply, internal power components, or a firmware fault caused by the sudden loss of power.
 

Here's a step-by-step approach to troubleshoot this:

Basic Power Reset

• Unplug the power cable from both the printer and the wall.
• Wait 1–2 minutes.
• Press and hold the Power button on the printer for 30 seconds to discharge any residual power.
• Plug the power cable directly into a wall outlet (avoid power strips or surge protectors).
• Plug it into the printer and try powering it on again.

Check the Power Module

• Ensure you're using the original HP power adapter (output: 32V / 12V).
• Check the adapter for:

Burnt smell

Fraying

Loose plug ends

• If you have a multimeter, you can test if it’s outputting the correct voltage.

Note: Faulty adapters are a common cause of this issue. If you suspect it’s dead, replacing the power adapter is often a solution.

Try a Different Outlet

• Move the printer to a known working outlet in a different room.
• This rules out circuit-specific issues or surges affecting that outlet.

I hope this helps. 

Take care and have a good day.
