I updated the HP 9130 firmware and encountered the same problem. I turned off the printer, removed all the printheads and the cartridges, closed the printer cover and then turned on the printer again. After seeing an error message on the printer screen concerning the missing printheads, I opened the printer cover, replaced all of the missing printheads and the missing cartridges and then closed the cover. The printer then aligned printheads once as is expected after replacing the printhead and cartridges. Thereafter, it worked normally. I do not know why this procedure worked and if it will work in every case, but for now, it seems to have worked for me.

Same problem with my printer, called tech guy charged 100 bucks for nothing. Actually changed the cartridges. All cartridges have to be new and check the date on the cartridges, if installing 2006 cartridges, just use all of the same date , if using 2007 just use that date. It should work fine after that.

What works for me is re-flashing the firmware, even if it is the latest version (3010D).

I heard about this happening with other HP printers. Sorry to say but it sounds the sensor unit in the HP printer might be broken. Your best bet is to call up HP and have them replace the printer if its under warranty if not you might have to return the printer for a new one.
