HI,
You've sent a print job to your printer and the green light is blinking, but the printer is not printing. The light blinks for a very long time.
The blinking light indicates that the printer is recieving your print request and will print shortly. If the document you are attempting to print is very large or contains many graphics or images, the printer must spool this data into its memory before printing. This can take quite a bit longer than usual. PDF files are notorious for taking longer than other document types.

In this case, it is best to wait a period of time before taking action. Give the printer 10 minutes and see if it prints.

If it does not print within this window of time, do the following.

1. In the bottom right corner of your screen, you will see a small printer icon. Double click on this icon to open the printer job menu.
2. You will see your print job located there, with other information, including its status.
3. Select the job by right clicking on it and select Cancel.
4. The job should cancel itself.
5. Unplug the printer, removing all power and leave it sit for a couple of minutes.
6. Plug the printer back in and allow it to go through its start up phase until the "Ready" indicator light is solid. This indicates that the printer is ready to recieve jobs.
7. You may now attempt to print again.

Thanks,
HP Printer Support

The blinking light indicates there is a malfunction; such as paper jam, cartridge missing or ink cartridge caddy has a problem (ink on bottom, or dryed up, etc; caddy can be pulled out and cleaned), or something you were going to print was not printed due to low on ink, etc. It may show a number that you could contact H/P support, give them model of printer and the error number and they may be able to assist. Actually, blinking light could be a host of problems. Take cartridges out and carefully clean the brass contacts and also on the printer head, clean that too. Edwin, USN-Ret.

Blinking drop light on HP6122 signifies an ink cartridge is out of ink. There are two cartridges -- color (larger of two) and black (smaller of two). Blinking drop light only indicates either, but not which. HP6122 service software and print driver are available from HP website http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?product=83027&lc=en&cc=us&dlc=en&lang=en&cc=us. HP6122 service software has a printer maintenance utility which includes ink cartridge monitor. Use the maitenance service utility to determine which (or both) cartridge is out of ink. With cartridge replacement, printer should automatically print test page, then reset and be ready for printing from your computer. To clear printed documents from print que, open the HP6122 print que via control panel > printers > double-click on HP6122 driver to show que > select document tab > select cancel.

Introduction The printer lights indicate the printer status. These lights can be on, off, or blinking (flashing), depending on the status of the printer. The sections below describe the most common combinations of blinking lights, how to fix the issue, and how the issue is caused. NOTE: The light patterns included in this document are described as blinking or flashing lights. For the purpose of this document, "flashing" means the same as "blinking." Blinking lights Printer lights can can blink for more than one reason, so the solution can vary. These solutions need not be performed in a specific order, but solutions for the most common issues are presented first. Blinking lights are often accompanied by an error message on the computer screen, which might help determine the solution. Issue: Power light is blinking

Solution

Cause

The printer is out of paper. Solution

• Change the printer's print mode setting.
• Change the printer's paper type selection.

1. Remove the paper from both paper trays.
2. Press the power button once. Wait a moment for the paper jam to clear.
3. If printing labels, verify that a label did not become detached while passing through the printer. If the paper jam was not resolved, continue on to the next steps.
4. Remove the rear access door.
5. Remove the paper jam through the opening at the back of the printer.
6. Replace the rear access door.
7. Reload the paper into the paper In tray.
8. Print the document.

1. Print a printer self-test by holding the power button down with a pencil and opening and closing the top cover four times.
2. Check the nozzle self-test pattern in the self-test print out. If one or more of the solid rectangular areas are missing, an electrical contact problem may be present.

the Toner light blinks.

Buttons and lights Purpose POWER button and light Push the POWER button to turn the printer off and on. When lit, the light shows that the printer is turned on. RESUME button and light The light blinks when there is a problem with paper. When the problem is corrected, press the button. Print cartridge light The light blinks when there is a problem with a print cartridge. When the problem is corrected and the top cover is closed, the light will stop blinking. Troubleshooting blinking printer lights Blinking lights Reason

All lights are off. The printer is off (asleep).

Press the POWER button to turn the printer on.

The printer should turn on automatically when a print job is sent to it.

The POWER (top) light is on. The printer is idle.

The printer is ready to print a document.

The POWER (top) light is blinking. The printer is busy printing.

Allow enough time to print. When a document has many fonts or graphics or uses complex color such as a color photo, it takes longer to begin printing.

The PRINT CARTRIDGE (bottom) light is blinking. Possible causes:

• The front cover is open. Make sure the front cover is completely closed.
• The print cartridge is missing. Make sure the print cartridge has been installed correctly.
• The print cartridge is broken or incompatible. Lift the front cover, and wait for the print-cartridge cradle to slide out. Check the part numbers on the print cartridge:

Black: 51645A

Color: C1823D,

If the print cartridges are compatible and correctly installed, they may be defective. Try replacing the print cartridges.

If none of the above suggestions fix the problem, and, if the error message still occurs, it may be a hardware failure. Call the HP Customer Support Center.
