When i try to turn on my printer it begins the loading screen, than after a couple minutes it goes black than to an orangish screen with the power symbol and a code 07a74dd6. The green light in the front flashes and it starts all over. Any suggestions?
-   I keep getting an error saying printer cartridge stuck, and to fix and press ok but it's not stuck and won't work?

-   I kept on getting the error message 07564DD6 from my HP Photosmart A516 and it would continuously reset itself.
I had a similar problem with my HP Photosmart 385 printer the only difference is the error code is 07A74DD6.
It is funny how little help I have got from HP.
Luckily the solution is simple. You need to use the power cord that came with the printer. I didn't even realize I was using the wrong one, especially since I have several products that use one.
Thanks a lot HP for nothing. -   ambermiller
As the previous message stated, I had the same problem and it was resolved by making sure that I used the original power cable. I couldn't find it at first and tried with three others all with the same error. Finally it was resolved by using the original.

The pinter has 2 cartridges - one regular black in and one for photos. The printer is only drawing from the photo black ink cartridge. I reloaded the regular black in cartridge, then shut of the printer, restarted it...its still did not make a difference.
