Printhead Storage
Printhead storage should take place, in the original/sealed packaging, under the following conditions:
Storage Temperature Range:
Long Term: 41°F to 113°F (5°C to 45°C)
Short Term: -13°F to 140°F (-25°C to 60°C)
NOTE: Cumulative storage duration below 41°F (5°C) or
above 113°F (45° 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
• Store the printhead with the printhead nozzles facing down. This helps to ensure that the shipping fluid,
within the printhead, keeps the nozzles hydrated during printhead storage.
• Exposure to conditions that are not permissible may lead to damage which is not externally visible.
Once the vacuum sealed packaging has been opened, the printhead should be immediately installed and it should
remain in the printer until it is determined that printhead replacement is required.
If you find it necessary to remove the printhead from the printer, it must be properly protected and sealed to help
reduce damage, nozzle dehydration and clogging.
• Follow the “Replacing the Printhead Cartridge” procedure to remove the Printhead Cartridge.
• Install the protective cover on the Printhead. Be careful to avoid ink spills (drips) and stains during this process.
• Store Printhead Cartridge in a sealed plastic bag, along with a small lint-free cloth that has been lightly
dampened with distilled water. This will create a humid atmosphere to help prevent nozzle dehydration.
• Reinstall the “Cap Protectors” onto the Ink Revolver Couplings to protect the ink system from dust and debris.
• The Printhead should be re-installed as soon as possible.
Please see the section titled “Install Printhead Cartridge”.
CAUTION: Make sure the cartridges electrical contacts are dry before re-installing Printhead.
Printhead Service Life
Manufacturer’s estimated rating: ~125,000 linear inches of continuous printing.
For example, if printing a #10 envelope (9.5” W x 4.13” H), feeding long-edge first, at best print quality, with 100%
ink coverage (each nozzle firing at 1600 dpi down length of media), the printer is depositing 4.13 liner inches of
print per piece. At this rate, you can expect a yield of approximately 30,000 envelopes before head replacement may
be needed.
If printing a typical logo (1” high) you can expect a yield of approximately 125,000 envelopes before head
replacement may be needed.
NOTICE: Individual results will vary.
The estimations, provided above, are NOT an expression of Warranty. This information is being provided for
informational purposes only. The decision on when a Printhead is no longer producing acceptable output varies
greatly from customer to customer, since this decision is based upon the customer’s expectations (what they
consider to be acceptable output).
Printhead degradation will depend on the make-up of the images printed, the operating environment, servicing,
media characteristics (including cleanliness) and other factors. The Printhead has a total of 70,400 nozzles (14,080
per color channel, 5 color channels). Since every print job is different, most do not use the entire width of the
Printhead, nor do they require that every nozzle be fired. Therefore, some nozzles do not fire as often as others. The
most frequently used nozzles will begin to fail (nozzle “end-of-life”) before nozzles that are used less often.
Noticing the effects of failing nozzles depends partly on the relative position of those nozzles to each other.
Printhead Disposal
The Printhead Cartridge should be disposed of in a safe manner in accordance with local/national regulation. To
help avoid ink spills, place the Printhead Cartridge back into its original packaging, before disposal. Clean up spills
with soap and water. Abrasive soap is effective in cleaning ink off your hands.
