Fix and Prime Printer ink cartridges

I use an 8" clear silicone tube to carefully prime stubborn or "defective" new and past-date laser printer ink cartridges by sucking a dab of ink (each color) out of the tiny print holes in the bottom (bareley visible microholes) to ensure flow before installation. I am careful to have a tight seal at the print holes to prevent getting too much ink and possibly getting it in my mouth. This doesn't fix all carts as some need to be reset with a tiny battery powered programmer, (available on eBay) which re-sets the date chip. There needs to be a bit of fresh liquid ink at the print head area in order to be activated by the electrical excitation/impulsing. You can loosen some dried or clogged carts by taping a bit of wet tissue over the printhead over night or slapping the printhead holes with a wet finger under running hot water. .Self print for many laser officejets and deskjets is power on pressed while plugging in the printer or holding some buttons for at least 4 seconds until it beeps then wait patiently for a minute. Surprise!! It doesn't need to be connected to your computer, you can test them at the thrift store.
