Printhead Storage
Store and transport the cartridge as indicated by the "this side up"
arrow symbol on the packaging.
The cartridge and ink supply must be within the operating
temperature range before attempting to prime the cartridge with ink
and starting to print. When stored at temperatures below the
operating range it may take up to 3 hours for a cartridge in its
packaging to reach operating temperature. NOTE: Additional
packaging will increase the time needed to reach operating temperature.
Storage Life: 12 months from date of manufacture (printed on shipping box).
Storage Temperature Range:
Long Term: 14° F to 86° F (-10° C to 30° C)
Short Term: -11° F to 140° F (-25° C to 60° C)
NOTE: Cumulative storage duration above 86° F (30° C)
must not exceed 72 hours.
Humidity Range:
5% to 95% Relative Humidity, non-condensing
Atmospheric Pressure Range:
70 kPa to 106 kPa
Electrostatic Discharge:
8 kV air discharges or 4 kV contact discharges*
*When tested in accordance with IEC 61000-4-2
Printhead Service Life
Projected: 50,000,000 ejections per nozzle. The Printhead has a total of 70,400 nozzles (14,080 per color
channel.) Since printing does not use the entire length of the Printhead, some nozzles do not fire as often.
The most often used Nozzles will degrade more quickly. Noticing the effects of failing nozzles depends
partly on the relative position of those nozzles to each other. In simple terms, the number of images printed
and the amount of ink that will pass through the printhead prior to printhead degradation will depend on the
make-up of the images printed, the operating environment, servicing, media characteristics (including
cleanliness) and other factors.

The following is the Return Policy and Return Procedure for Memjet Printheads for M-Series
Printers:
Limited Printhead Replacement Policy: M-Series Printheads are manufactured to be free from defects in

significant degradation of print quality prematurely, the Printhead may be returned for replacement.
Returns for these conditions can be made:
Up to 12 months after the shipping date from Astro Machine Corp. and
The Printhead's “Total pages printed” = 40,000 or fewer pages (at 15% page coverage), whichever
