Question about HP Officejet 6500 WIRELESS ALL-IN-ONE E709N Power Supply Adapter Cord
1. I have tried running the cartridge cleaner. No luck 2. I have tried running the extra deep cartridge cleaner. No luck 3. I hv checked that the breather slots are not obstructed on each cartridge. All OK. 4. I have tried taking out the printhead and cleaning all the contacts. No luck 5. I have switched OFF and ON again. No luck. 6. Reset: I have tried the recommended unplug while it is ON, waited a minute and plugged main back into the wall and the power plug back into back of printer. No luck. 7. Even tried my old printhead which I had very thoroughly rinsed and dried. No luck.
No real need for a cleaner anyhow. If you want to activate the heads you need Very Hot Water Only. Only hot water (too hot for touching with the bare hand) should be run over the print head. Run for several minutes to help the heads create the bubble effect (same as when electrically charged) and they self clean. Only the proper INK made for that cartridge will work, thus not every ink is suitable as an all-in-one solution. Any film (oil from your hands) left on the contacts (both on the shell and the printer contacts) will create a barrier. Contacts need to be cleaned with alcohol so all metal connections are true and correct. Some cartridges also have a CHIP the opens when the cartridge is removed from the printer. This chip is put there by the manufacturer to [prevent refilling their carts as they want people to pay fro new ones every time. Last: If the Printer circuit board has a short, it won't read the necessary data from the print head, thus it won't print at all.
