The print head and the circuitry
perform most of the work on an ink jet printer. And, in
most cases, these are not permanently installed in the printer
– they are contained on the small ink jet cartridge
itself. Today, there can be anywhere from 48 to 320 nozzles
or “jets” on a print head located at the bottom
of your inkjet cartridge.
Each of these nozzles is smaller than a human hair and
each is connected electronically to a heater (or resistor)
that actually heats and cools the ink inside the cartridge.
When the ink is heated, a bubble forms. When the heat source
is removed, the bubble bursts and sends dots of ink through
the nozzles and onto the paper in the printer. This heating
and cooling process happens at very high rates of speed,
creating dots that form print characters on the page at
rates of up to 6,000 drops per second.
It was previously believed that the heaters in ink jet
cartridges would only last for one use. Now manufacturers
realize that the heaters continue to do their work and the
nozzles continue to fire beyond one use on most inkjet cartridges.
In fact, the heaters on most cartridges will continue to
fire until they burn out completely or weaken significantly.
On the average, that happens somewhere between the fourth
and sixth time the cartridge is used.
For consumers, this information is useful in three ways.
One, remanufacturing
services can
extend the life of a cartridge without fear that the ink
jet printer itself will be ruined. If the “workhorse”
of the printer is the print head and circuitry contained
on the printer cartridge itself, then the most a consumer
would risk is the minimal fee involved in remanufacturing
the cartridge. Secondly, purchasing a compatible
ink jet cartridge instead of a brand name cartridge
cannot ruin a printer that does not contain a print head.
The print head and circuitry is on the cartridge, not in
the printer. Therefore, the consumer would again be risking
only the amount one paid for a generic inkjet cartridge
– not the cost of replacing an inkjet printer. And
lastly, it emphasizes the importance of purchasing compatibles
from a manufacturer that produces inkjet cartridges to the
same specs (ISO standards) as brand name manufacturers,
and backs that up with a strong guarantee.
Eventually, all ink jet cartridges will wear out. You should
know that this does not always coincide with when your cartridge
runs out of ink. If you start seeing horizontal bands, white
streaks, or incomplete areas with no ink – that could
be a sign that your inkjet cartridge is nearing the end.
There are some common inkjet cartridge problems that can
cause these same conditions. Check
our list of common fixes and if these don’t correct
your print problem, it is time to replace your inkjet cartridge.
Although ink jet cartridges won’t last forever, purchasing
economical compatibles and using remanufacturing services
will extend the life of most inkjet cartridges without harming
the inkjet printer itself. Compatible ink jet cartridges
are another economical option. These are original, new ink
jet cartridges that have not been remanufactured, but instead,
are produced by a company other than the printer manufacturer.
These cartridges can be purchased at lower prices than
their brand name counterparts, and then refilled.
There are patents protecting some brand name cartridges,
and compatibles will not be available for those model. However,
suppliers of compatible inkjet cartridges often offer brand
name cartridges as well, usually at a significant discount.
Compatible EPSON cartridges cannot be refilled with much
success. They have a very porous sponge in the cartridge
which fills with air as the ink leaves.
Compatible ink jet cartridges vary greatly in quality.
Ink ReStore only uses the best manufacturers and if there
are any problems that are cartridge related we will fix
them. We only use suppliers that manufacture their cartridges
using the same ISO standards as brand name manufacturers.
We have a “no questions asked” return policy
to assure you we stand behind the products we sell.
Finally, if you are worried about a generic ink jet cartridge
voiding the guarantee on your printer warranty, or even
ruining the printer completely, learning more about how
an inkjet printer works will help you allay your fears.
