Green & orange lights both flashing? Ink OK - HP DeskJet 3820 InkJet Printer

SOURCE: Green Light Flashes

I'm not sure what the problem is but try this.
Turn your printer off, wait for a few minutes, turn it back on and then run the "self-cleaning" process.

If that doesn't work try this:
Turn it off, take cartridges out, turn it back on, turn it off again put the cartridges back in and turn it on.

If none of that helped reply with more info.

Try changing the color cartridge. Also it is a good idea to clean the electrical contacts if it looks dirty.Use slightly damp(use water only) q-tips .
Hope this helps

click on start, then click run, type in the word services.msc, you will then get a list of options scroll down the lost to the letter p and find the word print spooler. click print spooler once then in the left corner you will have to options, either to stop or refresh, before doing anything take the usb out of the back of the printer, then click on stop, then click start, then click refresh, after this put your usb back in the printer, and that ''should'' solve the problem. email me if works or does not, thanks

Please follow these instructions to reset the printer. If that doesn't work, try again but wait longer before reconnecting. Otherwise, here's the home support page for your machine. You can look up the meaning of the flashing lights there as well.

SOURCE: cartridge light flashes ink drags across wide

The user manual says that indicator is for a bad ink cartridge.
But it doesn't say which one (so you have to check them all).
And it doesn't say why.
It recommends removing each, checking the contacts, and reinstalling the.
Otherwise is says replace the bad cartridge.
