Tools needed

  • water bottle to wet clean rags for cleaning cartridges
  • Simple Green cleaner for printer cases
  • #T10 torx bit for many HP inkjet printers
  • printer test machine with USB and parallel printer cables (and internet connection)
  • cheap plastic ziploc bags to put empty cartridges in for a given printer
  • known good cartriges (in special cartridge holders) to test printers with
  • extra labels to price the printer and mark the cartridge ziploc bags

Cleaning Inkjet Cartridges

  • Wet a CLEAN rag with a spot of water
  • With the wide face of your thumb under the wet area, rub the cartridge printhead over the top of the rag until all colors of ink flow out'
  • You can tap the printhead against the rag lightly to encourage the ink to come out
  • Move to dry area of the rag and drag the printhead over the rag on top of your thumb to make sure all colors are flowing freely
  • store cartridge in holder or in printer in "capped" position

Performing HP diagnostic "tap" sequences

Hold down the power button when the printer is on and press the button next to power either 1, 4 or 8 times, then release the power button. 1-tap is a simple demo page. 4-tap is often a diagnostic page. 8-tap is often a nozzle pattern or larger diagnostic

Refurbish Process

  • Get one of the suggested printers, open the lid and check for broken parts or spilled ink
  • Clean off the horizontal thin plastic encoder strip with water and power the printer on
  • Insert good cartridges and run "tap" sequences to verify operation (run a copy for All-in-ones)
  • For the 900 series of printers, most will print an alignment page as soon as you reinsert any cartridge and close the door. Check all colors.
  • Look up the printer model at or to get the cartridge number, if needed
  • Print a test page from the PC over USB
  • If good, clean off the outside case with Simple Green, assign a price for the store.
  • Replace good cartridges with empty or partially filled ones and power down the printer so the cartridges get locked inside
  • Put the printer in the store or on the "for-the-store" shelf
