I have a c7280 AiO that will not print or scan.

I have a c7280 running on Vista that just started having problems with copy and scan.  All I get is solid black copies.  I went through the process of turning off, unplugging etc. which helped only on time then went back to black.  The printer prints fine from the computer but not copying or scanning.

The lightbulb in the scanner may have burnt out in the printer,

Your best bet is to plug it directly into the wall outlet and preform a reset

With the printer on, unplug the power cord from the back.

Hold # and 6 down on the printer.

While Holding those down, plug the powercord back in.

Continue holding those buttons down for approx. 10 seconds.

This should reset the printer and it should prompt you for language and region.

The light goes back and forth across the glass.  After trying solution the preview now shows black with some colored horizontal lines.

Try the same procedure as above but with # and 3

same results. Most of page is black with a column of white with horizontal color lines on the right and color horizontal lines in the black part.

Try powering it to a wall outlet, if that doesn't work then I am out of ideas and replacement may be the only option.

Black page scans/copies on a printer than can still print normally are a strong indication of scanner module damage. If the problem isn't corrected by a power cycle, then I'm afraid you have a hardware problem. If you're still in warranty then you should call HP.
