It's hard to believe this story is true, but I assure you it is all true. 1- In October 2009 we purchased an HP Officejet Pro 8500. Not long after installing it we got constant messages "Printer is offline." Called HP and learned that it was a hardware fault and could only be resolved by sending us a new printer. 2- A new HP Officejet Pro 8500 arrived by FedEx with instructions how to remove specific parts from the old printer and send it back within a specified number of days or we'd be charged for the new printer. We set up the new printer and while setting up we get the message "Printhead error." 3- We call HP. They say the only solution is to send out another new printer. This story goes on-and-on. We are now sitting here 14 months later with the FOURTH HP Officejet Pro 8500 sent to us by HP via FedEx and when turning the printer ON it tells 1) Cyan cartridge is low. But it's a brand new cartridge. 2) the Printhead problem is here again. Did I mention this is the FOURTH printer that they've sent to us? When we call HP it's like starting from scratch every time. No one has a complete, accurate record of these extraordinarily bad experience with HP. We have to walk them through step-by-step what we've been through. We must almost beg them to quit putting us through this. Tomorrow I think we'll go out and buy a new printer by Canon or Epson or just any printer that's not HP and meanwhile we'll just let HP keep sending us new printers because it seems like they have endless resources to throw away rather than to just simply solve our problem. What has happened to what was once a great company? This is truly pathetic. How much money has HP spent sending us new printers and getting the old printers back via FedEx? I want to find every forum possible on the Internet to make users aware of this kind of service and response from HP.
