droplets onto the paper) â these will eventually fail depending on print usage type and printer duty cycle
(i.e. rated for approximately 12,000 printed pages over life, but the consumer average is typically closer
~6,000 thruput pages). The printhead may be replaceable and can be ordered directly from Epson.com
or Amazon.com (though not easily customer replacable!). For information on how the PRINTHEAD
functions, please watch the following video: http://inkjet411.com/?page_id=2054
Typically the printhead should not reach itâs 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 âhead strikesâ of the paper edges making repeated contact with the
printhead nozzle plate surfaces.

QUESTIONING OF COLOR/INK PERFORMANCE (REFILL SERVICES - QUALITY ASSURANCE)
Regarding your recent inquiry about the HP 920 cartridge color print quality problems, specifically color
matching, customer feedback has been extremely favorable to date. The inks (within the ink refill
system) are closely matched across several manufacturers and provide satisfactory color performance
from in-house testing performed. While not an exact color match to the HP 920 CMY inks, they have
been tested for general color appeal and comparison performance; passing all quality performance
expectations. Many customers (i.e. in the tens of thousands) are quite pleased with Costco's HP 920 ink
refill service since inception.
As far a general color print performance, there are other things which could be causing the Cyan issue
you are seeing.
1) Run a self test print (under tools/maintenance menu) to ensure all magenta (and cyan & yellow) ink
nozzles are firing. We would be very interested in receiving a .pdf of the self-test print (or one of our
Test Prints) to evaluate your Cyan ink color performance...is it possible to mail an electronic file to us via
the 'Contact Us' form?
