You press the power button and nothing happens: no lights, no sound, no screen. Before assuming the printer has died, rule out the simple causes, because deep sleep, a cord that has slipped out of its socket and a dead outlet all look exactly like a hardware failure. This guide works from the outside in, from sleep and the cord to the outlet and power source, then a safe reset, and explains the signs that mean it's time to arrange service.
What you might be seeing
- No lights, display or sound when you press the power button
- The printer worked yesterday and is now completely dark
- The power light flickers briefly, then goes out
- An external power adapter's light is off
Common causes
- Deep sleep or scheduled off
- Many printers power down fully after a set time or on a schedule and look switched off.
- Loose cord
- The cord can work loose at the back of the printer, especially after it's been moved.
- Dead outlet or strip
- A wall switch, a tripped GFCI outlet, or a switched-off or worn-out surge protector can cut the supply.
- Faulty cord or adapter
- A damaged cord or failed adapter stops power reaching the printer.
- Internal power fault
- If power reaches the printer and it still won't start, the internal supply or main board may have failed.
How to fix it, step by step
Work through these in order and test a print after each one. Most people are done within the first few steps.
If you notice a burning smell, scorch marks, a damaged cord or liquid inside, unplug the printer and don't switch it on again.
Rule out deep sleep
Press the power button once firmly and release it, then touch the screen or press another button. Some printers need the button held for a second or two. Wait a full minute, since a printer leaving deep sleep or a scheduled power-off can take a moment to light up. If it starts, check its energy settings later for an auto-off timer or schedule.
Reseat the power cord at both ends
Follow the cord from the printer to the outlet. Push it firmly into the socket on the back of the printer, where it often works loose when the printer is moved or a tray is pulled out. Then unplug it from the wall and plug it back in snugly. If the printer uses an external power adapter, check both of its connections and look for a light on the adapter.
Test the outlet
Plug a lamp or phone charger into the same outlet to confirm it has power, and check for a wall switch that controls it. If it's a GFCI outlet with test and reset buttons, common in kitchens, bathrooms and garages, press Reset firmly. If it trips again straight away or still has no power, stop using it and choose another outlet; repeated tripping needs a qualified electrician.
Plug in directly, then use a surge protector
Take the printer off extension cords, basic power strips, timers and smart plugs, and plug it straight into a working wall outlet to test. For everyday use, choose a surge protector over a plain power strip, and check that its switch is on and its protection light is lit. Keep laser printers off the battery-backed outlets of an uninterruptible power supply, because their warm-up draw can overload it.
Drain leftover power
Unplug the printer and disconnect any USB or network cables. Wait at least 60 seconds so leftover charge drains away, and press and hold the power button for about 15 seconds while it's unplugged. Plug the power cord back in, leave the other cables off for now, and press the power button once.
Try a known-good cord
Many printers use a standard detachable power cord like those on monitors and desktop computers. If yours matches exactly, borrow a known-good cord of the same type to test. If the printer uses an external adapter or an unusual connector, don't substitute one from another device, since the voltage may differ; get the correct replacement from the manufacturer.
Recognize when it needs service
If the outlet works, the cord is good and the printer still shows no sign of life, the fault is inside, usually the power supply or main board. Don't open the casing or attempt any repair to the power section, which can hold a dangerous charge even when unplugged. Note the model and serial number from the printer's label and check its warranty.
How to keep it from happening again
- Use a surge protector rather than a basic power strip
- Route the cord where it can't be pulled or pinched
- Switch off with the printer's power button, not at the outlet
- Know your printer's auto-off and schedule settings
Common questions
Can a storm or power surge kill a printer?
Yes. A surge can damage the power supply or main board, leaving the printer completely dead. A surge protector reduces the risk but can't remove it, and unplugging equipment during severe storms is safest. If the printer died right after a storm, check the outlet and protector first, then arrange service.
Why does my printer only start if I hold the button?
Some printers are designed to need a press of a second or more so they don't start by accident. If yours used to start with a quick tap and now needs a long hold, the button may be sticking or worn. Check for dirt or spilled liquid around it, but don't pry it out.
Is it safe to leave a printer plugged in all the time?
Generally, yes. Printers are designed to rest in sleep mode, and inkjets need power to run maintenance that protects the printhead. Use a surge protector and turn the printer off with its own button rather than at the wall, so it can park and cap its parts properly.
