HP Deskjet 845c only prints blank page no matter what

[aajayunlimited]

HP Deskjet 845c printer will only print a blank page.

Condition of Printer and what I've tried: It was given to me by a neighbor to keep. Before that, I'm sure that it had been sitting up for a while. It was a little dusty. I cleaned the leads on the cartridges and the holding area leads with lint-free medical gauze and a little store bought bottled water(and dried them), but still nothing. The cartridges still have ink in them, because the warning light for ink is not lit. ONE OR TWO OF THE TINY COPPER REGIONS HAD A BLACK STREAK ON IT THAT WAS CLEANED OFF AND I COULD NOT TELL IF ANYTHING ELSE WAS WRONG JUST BY LOOKING. I've tried to print a test page. I've cleaned the  printer using the printer software. I went through the process of automatically adjusting the heads, but that did not solve anything. Again, it only prints a blank white page. The ink cartridges are the right ones, too, because they are clearly labeled inside the printer by the HP factory. THANKS ALOT IN ADVANCE FOR ANY HELP YOU CAN PROVIDE AND FOR TRYING TO HELP ME!

What else should I try?
