If you find it necessary to remove the Printhead from the printer, for a few hours/days, 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 cloth that has been dampened with
distilled water.
•
Reinstall the “Cap Protectors” onto the Ink Revolver Couplings.
•
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 as 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.
