Xerox Black Cartridge  
8R7638

PLEASE NOTE: If you have tried printing with your cartridge completely out of ink, you may have damaged the printhead. Inkjet printers work by heating a resistor inside the printhead which heats the ink before it is sprayed onto the paper. If there is no ink to keep the resistors cool, you stand the chance of frying them.

Always refill before you are completely out of ink.

1. Drill a hole on the front of the cartridge where indicated...1/2 inch from the top.
2. Fill the syringe with ink, insert the needle into the vent hole and push down into the center of the cartridge. Note: The cartridge contains felt, so when the needle hits the felt, stop. Slowly inject up to 35ml of black ink into the cartridge.
3. Seal the hole with tape.
4. Set the cartridge on something (ie: block of wood) that will allow the printhead to hang off the edge, allowing any excess ink to drip onto a paper towel. Let it sit until the cartridge stops dripping. Do not allow the printhead to touch the paper towel because the ink will be wicked out. The vent hole need not be sealed unless you plan to transport the cartridge or store it for some time. If you need to seal the hole for some reason, electrical tape will do a nice job..

Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
