Printer Blinking Light? What Every Flashing Light Means (HP, Canon, Epson, Brother)

Quick answer: A blinking printer light is a status code. A slowly blinking power light usually means the printer is busy (printing, warming up or finishing a job), so wait for it to stop. A fast-blinking power light, an orange or amber light, or a lit "!" icon means an error: open and close the doors, clear any paper jam, reseat the ink or toner, then power-cycle the printer. A blinking blue or Wi-Fi light means the printer is searching for, or has lost, its wireless network. On Canon printers, count the orange flashes; the number points to a specific support code.

Key Takeaways

• A slow, steady blink on the power light almost always means "busy." Don't unplug the printer mid-blink.
• Fast blinking, orange/amber or a "!" icon means an error that stops printing: an open door, a jam, a cartridge problem or empty paper tray.
• On HP DeskJet and Smart Tank models, a flashing "A" usually means the printer printed an alignment page and is waiting for you to scan it.
• Canon printers blink the orange Alarm lamp a set number of times. 2 flashes = no paper, 3 = jam or cover open, 4 or 5 = cartridge problem, 13 or 16 = ink out.
• A blinking Wi-Fi light means the printer is trying to connect or has lost the network. Re-run wireless setup or WPS.
• If every light flashes at once, it is usually a hardware or carriage error. Power-cycle first, then check for stuck paper or packing material.

Why Is My Printer Blinking?

Your printer is blinking because it is either busy or reporting a problem it can't show in words. Printers without a screen use light patterns instead of error messages, so the color, speed and combination of lights is the message.

Start by noting three things: which light is blinking (power, Wi-Fi, ink, paper, alarm), what color it is, and how fast it blinks. Then use the brand sections below. If your printer has a touchscreen, check it first; it usually spells out the same error the lights are signaling.

What Does a Blinking Power Light Mean on an HP Printer?

On most HP inkjets, a blinking power light means the printer is processing a job, and a fast-blinking power light means there is an error. HP's DeskJet 2700 user guide spells this out: a blinking Power button light means the printer is processing a job (press Cancel to stop it), and a fast blink means an error, often an open cartridge access door.

1. If it's a slow blink: wait. HP printers blink while printing, warming up after sleep and running cleaning cycles.
2. If it's a fast blink: open and firmly close the cartridge access door. Make sure the scanner lid and output tray are where they belong.
3. Clear the path: check the input tray and under the cartridge carriage for jammed paper or a stray scrap. See how to fix a paper jam by brand.
4. Reseat the cartridges until each one clicks.
5. Read the message on your computer or phone. HP's guide notes that if the printer shows no message, sending a print job generates one in HP Smart or the print dialog.
6. Power reset: with the printer on, unplug the power cord from the back for 60 seconds, plug it back into the wall (not a power strip) and turn it on. Details are in how to reset an HP printer.

What Does a Flashing "A" Mean on an HP Printer?

On HP Smart Tank, Ink Tank and some DeskJet models, a flashing "A" means the printer has printed a printhead alignment page and is waiting for you to scan it. Place the alignment page face down on the scanner glass and press the Color Copy (Start Copy Color) button. The "A" stops once alignment is complete. If it keeps flashing, re-run alignment from HP Smart. Our printhead alignment guide covers every brand.

What Does an Orange Light on an HP Printer Mean?

An orange or amber light on an HP printer means attention is needed: typically paper out, a jam, an open door or a cartridge problem. If the ink icon is blinking next to it, the cartridge is low, empty, not seated or not recognized. Our guide to "ink cartridge not recognized" errors walks through the fix.

Why Is the Wi-Fi Light Blinking Blue on My HP Printer?

A blinking blue Wireless light on an HP printer means it is in Auto Wireless Connect setup mode or is trying to reach your network. A steady blue light with signal bars means it is connected. HP's DeskJet 2700 guide describes the blinking blue light with cycling signal bars as setup mode. Finish setup in HP Smart, or follow our HP Wi-Fi fixes.

What Does a Blinking Orange Light Mean on a Canon Printer?

On a Canon PIXMA, a flashing orange Alarm lamp means an error, and the number of flashes identifies it. Watch the lamp, count the flashes between pauses, and match the number to the table below. These counts come from Canon's own PIXMA iP2800-series manual; most PIXMA models without a screen use the same scheme.

Power and Alarm lamps flashing alternately is a printer error, not a supply problem. Canon lists 2 alternating flashes as support code 5100 (often a carriage blocked by paper or a foreign object), 7 as 5B00/5B01 (ink absorber full; needs service) and 10 as B200 (contact a service center). Turn the printer off, unplug it for a few minutes, remove anything blocking the cartridge holder, and try again. See Canon printer error codes and how to reset a Canon printer.

Why Is My Epson Printer's Light Blinking?

On an Epson EcoTank or Expression printer, a flashing power light means "busy," a flashing paper light means a jam, and power plus paper lights flashing together means the ink pad is near the end of its life. Epson's ET-2700 manual lists these patterns:

If the pad message appears, read Epson "Service Required": your waste ink pad is full. For an Epson that blinks normally but won't print, start with Epson printer not printing: 10 fixes.

What Do the Lights on a Brother Laser Printer Mean?

Brother laser printers without a screen use separate Toner, Drum, Paper (or Error) and Ready LEDs. On the HL-L2312D, for example, Brother says the Toner LED means toner is low, the Drum LED means the drum is nearing the end of its life, the Paper LED signals a feed problem such as a jam, and the Ready LED blinks to show status.

• Toner light on or blinking: toner is low or needs replacing. If it stays lit after a new cartridge, the counter may need a reset. See how to reset a Brother toner cartridge.
• Drum light on: the drum unit is near the end of its life. Replace it and reset the counter: how to replace and reset a Brother drum.
• Paper/Error light: check the tray, the back cover and under the toner/drum assembly for a jam.
• Wi-Fi light blinking (wireless models): the printer has lost its access point or is still connecting. See how to connect a Brother printer to Wi-Fi.

What Does a Blinking Wi-Fi or WLAN Light Mean?

A blinking Wi-Fi or WLAN light means the printer is searching for a network, waiting for a WPS button press, or has lost its connection. A solid light means it is connected; an off light usually means wireless is turned off.

1. Restart the router, then the printer.
2. Make sure the printer is on the 2.4 GHz band if it doesn't support 5 GHz.
3. Re-run wireless setup from the printer's app or panel, or use WPS (what a WPS PIN is and where to find it).
4. If the printer shows "offline" afterward, see why your printer keeps going offline.

For what the letters themselves mean, read What Does WLAN Mean on a Printer?

Why Are All the Lights Flashing on My Printer?

When every light flashes at once, the printer has a general hardware, carriage or firmware error rather than a simple supply problem. It's often caused by something blocking the print carriage: a folded sheet, a paper clip or leftover orange packing tape on a new printer.

1. Turn the printer off and unplug it for at least 60 seconds.
2. Open the access door and look along the carriage path with a flashlight. Remove paper scraps and packing material.
3. Gently slide the carriage by hand (printer unplugged). It should move freely.
4. Plug the printer straight into a wall outlet and turn it on.
5. If the lights keep flashing, run the brand's reset, then contact support. A printer that still won't start is covered in printer won't turn on: fixes by brand.

Does a Blinking Ink Light Mean My Cartridge Is Empty?

Not always. A blinking ink light can mean low ink, an empty cartridge, a cartridge that isn't seated, or a chip the printer can't read. Check the estimated level in the printer app first. If the level looks fine, remove the cartridge, check the contacts for tape or dried ink, and reseat it. Learn how to tell if an ink cartridge is really empty.

Frequently Asked Questions

Is it safe to unplug a printer while the power light is blinking?

Wait if you can. A slow blink usually means the printer is finishing a job or parking the printhead, and cutting power mid-cycle can leave the head uncapped. If it blinks for more than a few minutes, then power-cycle it.

Why is my printer blinking but not printing?

A blinking light that doesn't stop usually means an error is waiting for action, such as a door ajar, empty tray or cartridge issue. Check the message on your computer or printer app, which often gives more detail than the lights.

What does a blinking resume or "!" button mean?

It means the printer paused and needs you to fix something, then press Resume (or OK) to continue. Common causes are paper out, a jam or low ink.

How do I stop my Canon printer from flashing orange?

Count the flashes, fix the cause from the table above, and press the Resume/Cancel button. Two flashes is the most common: add paper and press Resume.

Why does my HP printer keep blinking after I replaced the ink?

The cartridge may not be seated, may still have its protective tape, or may not be recognized. Reseat it, remove all tape, and power-reset the printer. If the error names the chip, see our guide to HP's "Non-HP Chip Detected" message.

What does a solid orange light mean?

A solid orange light usually indicates an error that needs attention, like paper out or an open cover, rather than an active process. Check paper, doors and cartridges, then press Resume.

Why does my Epson printer blink when it's off?

Many printers keep a status light pulsing in sleep or standby. If the printer was shut down incorrectly, Epson's guide notes the ink and paper lights can stay on until you clear the error and run a nozzle check.

Can a firmware update cause blinking lights?

Yes. During an update the lights often blink in unusual patterns; don't unplug the printer. A failed update can leave lights stuck. Epson reports this pattern as a firmware update error that needs a USB reconnect and retry.
