HP deskjet 5550 will not print. Flashing orange and green lights. There is no paper jam. I have reinstalled the printer, restarted the computer, unplugged the printer. It was working fine, then stopped in middle of a print job. I have cancelled everything in the queue, but to no avail.

Issue: The Power light is on and the Resume light blinks

In this error condition, the following light pattern displays on the product control panel:

•Print Cartridge status light : Off
•Resume light : Blinking (orange)
•Power light : On (green)
Causes

??¦The product is processing a print job, or waiting for the ink to dry on a document.
??¦The product might be out of paper.
??¦The product might have a paper feeding issue or a paper jam.

There are several possible solutions. To work through these suggest you follow the illustrated on-line guide found here.

THIS IS A CARTRIDGE OR PAPER JAM ERROR.CHECK FOR ANY PAPER STUCK IN THE PRINTER,ALSO TRY REPLACING INK CARTRIDGES

Check that there still isn't a piece of paper jammed in the mechanism. Also check that the paper out sensor isn't stuck. Delete the item from the print queue and reboot both the printer and computer.

remove the catridge and see also the steel rod is not dry apply some lubricant oil on the head rod.

1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.) 2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.) 3) While holding the Power button, press the Resume/Cancel button 3 times, and then release the Power and Resume/Cancel buttons. 4) When the LED stops blinking and lights in green, press the Resume/Cancel button 4 times. Finally press the Power button.

Hi Girlemom. Just had the same problem here. Lift up the lid and slide the ink cartridges to the left. If they are stuck in the middle, this will prevent the printer from starting properly. Then, unplug it, plug back in, and turn on. It should restart normally.

Please go the this link at the HP online support site and follow the instructions given for your error lights to adjust the printer clutch.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Did you peel the piece of paper on the ink cartridge?Or if that doesnt help do this get the cartridge out and then dip some water on the ink leaking part with a piece of paper and well see what will happen.
