The printhead is part of the print cartridge. It is replaced when the print cartridge is replaced.
The OkiJet 2010 is a thermal inkjet printer. It sprays liquid ink onto the print media.
The inkjet printhead-to-media gap is very small. A crease or sharp edge on the paper may damage the
inkjet head. Paper dust or other contaminants can clog the inkjet nozzles on the printhead.
Perform the nozzle test to clean the inkjet nozzles. Refer to Section 3.3 for further information.
Inkjet printheads are delicate and easily damaged.
