Ok my HP Photosmart 8250 has been in the cupboard for about one year now.  Before I put it in storage it worked fine.  And yes maybe I screwed up by not taking the ink cartridges out too?  Nonetheless it says Ink Error 0xc18a030a when ever I attempt to print on it now.

Maybe the ink in the cartridges degraded or you have to clean the printing heads on the cartridges try the customer service.

Thumbs and testimonial are welcome!

Try downloading the photos off the SD card by inserting the SD card into anUSB card reader and connecting it to a computer's USB port.
This computer should detect the SD card as an external storage device, then you can copy the photo from the SD card to your computer's hard disk.

you need to have authentic hp cartridges,if you bought cheaper,it will not work.

Go to Control Pannel and Add remove Programs
and
Uninstall the HP Photosmart 8250 Inkjet Printer Drivers

ok..do us a favor here..try a test page from printer selection panel. just to make sure it's not the printer..you may need to re install new printer drivers.

I had same problem with hp psc 2410 all-in-one. Finally ran "HP all-in-one Series Web Release Uninstaller version: 4.1.1.00.1332 (3/20/2007) that I had downloaded several years ago. Then plug and play took over and installed the correct driver that Vista kept insisting I already had.

plz refer to the link

The cartridge maybe beyond its expiry date ??
If this is the case then try winding back the clock on your computer and see if it recognises the cartridge.

do you mean the installation CD of printer ? let me know
