I too was getting the seven (7) alternating orange and green flashing lights signal. My printer was non-responsive to any of the Maintenance requests like: Print Head Alignment or Print Head Cleaning. The print head didn't even move to the center position when I opened the front panel to check the ink cartridges. I checked the manual and it clearly states that 7 flashes indicates a Print Head problem. So I combined the "expertise" in this forum and had great success.
First I turned the Printer "off"
Next I removed the ink cartridges and carefully set them upside down on the desk.
I then wiggled the blue paper thickness lever back and forth about 10 times.
Then I raised the grey lever and removed the entire Print Head from the Printer. It was clogged with a gummy ink jam at the bottom of the head. So I ran it under warm water, trying not to get any on the copper leads, until all of the ink was washed away. I had to rub a few spots with my fingers to assure that all of the ink was gone. After washing I "dabbed" a paper towel over the components so as not to bend or damage anything.
I then replaced the Print Head, put the grey lever back down to seat the Print Head in place. Then I replaced the ink cartridges where they belonged.
Next, with the Printer still "off", I pushed and held the Resume until I pushed and held the Power button. (It is very important to hold the Power button.) While still holding the Power button, I released the Resume button, then pushed the Resume button slowly two more times. When I released the Resume button that last time, I simultaneously released the Power Button.
As stated in this forum, the green indicator flashes during initiation. When the green indicator stopped flashing and remained on, I pressed the Resume button 4 times to clear the waste ink message. Everytime I pressed the Resume button the indicator light alternated between green and orange.
Then I pressed the Power button, and the green indicator lit up and stayed lit up.
Finally, I turned off the printer, waited 10 seconds and then turned it back on. The error was cleared and the Printer Status window popped up and asked if I had just changed an ink tank.
Answer yes, reset your ink counter and you are ready to print.
Hope it works for you.
