Turn on the printer and open-top spread to cartridge compartment. In the event that you are utilizing an HP Photosmart, trust that the cartridges will stop in the center before expelling them. Be mindful so as not to contact the printhead.
Next, lift the switch that bolts the cartridge compartment. Evacuate the cartridge compartment.
Your ink cartridges may be alright and new yet your print head may be loaded with gunk and dried inks.
