There should be a support number or website on the box. Call HP, they have model-specific tools and tests to get it working. Also, they will replace the cartridge if it proves to be defective. There is no charge for this, even if the printer is no longer under warranty. The new HP cartridge is under it's own warranty. Not trying to send you away, but we aren't experts and have no ability to replace the defective cartridge.

".....and here just recently it will only print out a blank." Does this mean it use to operate properly with W7? If this printer was moved from an XP system to a W7, did you research as to new drivers? XP is two generations of O/S behind and facing extinction. You would be doing yourself a disservice to go backwards. Plus, you would be relinquishing improved performance and security. The concerns I have read and heard as to W7 are mostly the same following any new O/S release. Some users just don't like change or are afraid of it. Remember Vista got bad mouthed because of change, and actually it is a fine O/S. It's code is 80% of W7 with Vista designed for security while W7 was designed for performance. And wait until this time next year when W8 is available. Also, this time the O/S change concerns are amplified as XP was the largest O/S release ever and it was released to the largest spectrum of first time computer users ever. I could expand more, but mo matter how delicately and politely I put it there would be someone offended. I agree with my good friend Grandms. If this is an older XP generation printer, and your finances allow it, a new printer should be considered. DA

I've got a HP All-In-One prnter, HP Photosmart 3210xi. Its a printer, copier, and scanner. This particular model has USB port. The next model changed the ports, but was essentially the same machine inside. I got this printer because I needed to have achival quality ink for genealogical records, and to print photos. This printer uses 6 cartridges of HP's Vivera ink, and fixed print heads. This printer has worked well for me. The inks are pricey, but the black cartidge does print a reasonable number of pages. To date, I have run 8000 sheets of paper through this machine. I was concerned about clogging of fixed print heads, but that has not occurred. However, I do follow, without fail, HP's instruction to shut the printer off and allow time for it to store the print heads, before removing power. Other HP printers had the print head on the ink catridges, thus, a clogged print head could be fixed by changing the cartridge. The fixed print head was a concern of mine since I had bad experience with a Tektronix printer with fixed heads at my work (when ink jets first became available way back in the 1980s.) Happily, I have not had a problem with my print heads and I have owned this printer for 2 years. The printer does have a habit that startles the user until he becomes familar with it. The printer has an automatic maintence program built-in to keep the heads and ink supply in shape. Periodically, the maintence program will start and may startle the user. The printer is not available for use while the maintence routine runs. There is no recourse but to wait. The maintence routine lasts from 30 sec to 1 minute. Ink cartridges are sold singlely, or in a pack of 6 cartridges with 50 sheets of 4"x6" photo paper. This photo pack, at first, appears to be a good deal until one learns that there is less ink in these cartridges than the regular ones. There is just enough ink to print the number of photo sheets in the package. I found it was economical to buy a couple of these photo packs collecting more photo paper than I would use for awhile, and then switch to buying the regular cartridges. The inks and printer does print nice photos when the special photo paper is used. One caveat: the ink is not as resistant to running if exposed to water droplets as one might hope based on advertisements. It smears even after a drying time of 1 day. But protect the ink from wetting, and the results are fine.

I have found that this problem occurs because the carriage is in the wrong place. Use the following steps. Turn off the printer. open the door. If the carriage holding the cartridges does not rest at the proper place Ie where you can get the cartridges out then slide the cartridges to the correct place. Now shut the door and fire up the printer. You should not be asked to align
