8. If the problem persists, then you may have a damaged PRINTHEAD (worst case scenario),
unrelated to the refilled cartridges. The printhead is a separate electronic assembly (which the
cartridges are installed into) and is responsible for firing the ink drops onto the paper. Over time
and based on usage this assembly will eventually fail (typically lasts ~4,000 to 5000 printed
pages on avg). Refer to video on how the PRINTHEAD functions:

PRINHEAD TECHNICAL NOTES:
IIT (individual ink tank-based) printer models have an electronic PRINTHEAD within the base of the
carriage assembly (responsible for pulling ink from the 4, 5 or 6 ink cartridges and then firing the ink
droplets onto the paper) – these will eventually fail depending on print usage type and printer duty cycle
(i.e. rated for approximately 10,000 printed pages over life, but the consumer average is typically closer
~4,000-5,000 thruput pages). The printhead is replaceable and can be ordered directly from the
manufacturer or www.Amazon.com . For information on how the PRINTHEAD functions, please watch
the following video: http://inkjet411.com/?page_id=2054
Typically the printhead should not reach it’s end-of-life until after a minimum of 8 or more complete
sets of cartridge changes. While some printheads may last 10,000+ pages others may only last 2000
pages, actual results will vary. The printhead will eventually fail in time due to an internal micro-
electronics failure, due to the following leading factors: general customer print usage and printer care,
printer duty cycle (i.e. # pages printed per month), printing frequency (i.e. time between each print job),
print mode (i.e. draft vs. normal) and content printed (i.e. photos vs plain pages) and color mode (black
and white only vs. color/greyscale printing).
Paper types used (i.e. plain paper, photo papers & matte/heavy bond papers) and paper edge curl (i.e.
duration in printer and/or exposure to low relative humidity) can also quickly lead to premature
printhead failures due to physical ‘head strikes’ of the paper edges making repeated contact with the
printhead nozzle plate surfaces.
