it doesn't look like anyone is taking you up on your generous offer. I have a color laser printer so no more ink. Maybe you can donate them to a school near you, and there's always freecycle, or barter for it on Craigslist.

Glenda, go to www.staples.com - they have a 20% off coupon in the weekly ad (good for the purchase of one item). If you take in your old cartridge this week, you can get a $6 rebate credit. I usually either buy at Staples, or through www.hp.com (if HP sends me an e-mail about a sale, with free shipping). Yes, the cartridges are expensive, but I only use HP brands. I tried an off-brand one time, and it was worthless.

A shot in the dark here. It's an old HP fix-it. Shut down your system. Disconnect printer from system. Unplug printer from the wall for sixty seconds. (If it is plugged into a surge suppressor/power strip unplug it from the strip.) Reconnect printer to system. Plug printer back in directly to wall. Turn on printer and let it configure. Boot up system. Cross fingers. Print. The thought process is some HP transformers are fussy and don't like an unstable electrical supply; particularly through power strips/surge suppressors (two different things in actuality) In their fuss they can drop settings, handshakes and configurations.

Here's the website support doc for your printer, Sue. I've ticked the Tutorial Section to see, for myself, what might be available and it looks like there may be help utilizing one or more of their offerings. As you know better than I exactly what's going on with your printer...I'm leaving the rest of the investigation up to you. Although...I tend to agree with your current assessment...that something is blocking the ink flow. In some printers you can remove the print head and soak it in warm water until the dried ink is cleaned from the head. Warm water is usually the strongest cleaning solution that you should use so don't try alcohol or any other solvent unless HP recommends it. I know little to nothing about HP printers so I don't want to guess regarding corrective measures. Do some motoring around through their entire web site. There's a lot of really valuable info on there. I wish my Canon website was as nicely organized. While you're there, you might want to see if there have been any updates to your printer's program or new drivers. Windows usually makes these types of updates available through their own monthly updates...but I've personally found that they miss some here and there so it pays to check.
