of an internal micro-electronic failure. It is discouraged to use old ink cartridges which have been left in
a drawer as internal corrosion of the electrical wire runs can occur in a period of time.
However, if your printer works routinely after inserting a brand new Canon ink cartridge in it, you should
discuss the possibility of a refund with your local Costco (for the refilled cartridge purchase - just tell
them you validated the cartridge failure with the Inkjet411 tech representative). We regret your
inconvenience, and we hope that you will continue to consider the compelling value of inkjet refilling in
the future.
We trust this detailed technical information provides you some additional insight into the issue you have
endured. If, at any point in the future, you would like information on the most 'refill friendly' printer
models just let us know. Here is a sample of such models we support today:

The fact that you have experienced 2 cartridge failures in a row is either a coincidence, the ink cartridges
are past their useful usage date (see NOTE below) or your printer is suffering intermittent connecti vity
issues.
As the cartridge's ink nozzle plate (i.e. bottom of ink cartridge) contains all of the micro-electronics, no
damage can occur to the printer as a result of a cartridge 'short'. Assuming the printer's flexible printed
circuit cables (inside the printer - where the ink cartridge mates to the printer) are thoroughly clean and
not damaged, then the failures are limited to the ink cartridges themselves........this is the case most (i.e.
99.9%) of the time based on our observation of reported cartridge failure and or detection issues.
For reference, the following page provides a complete review of the majority of cartridge error
messages and causes of failure that you may observe on your printer at one point or another:

NOTE: The more severe printer error messages which result in non-permitted print operations,
represent a very small percentage of the mass experience (HP 93/95/97/99 cartridge family specific), so
please consider the problem you encountered as being relatively rare (1-3% range). The HP 93/95/97/99
ink cartridge electrical wire runs, at rear and lower sides of the ink cartridge, are very delicate and are
considered somewhat susceptible to ink attack and subsequent damage, which can lead to premature
failures. In addition, the older the cartridge the higher the chance of an internal electrical failure. It is
discouraged to use old ink cartridges which have been left in a drawer - internal corrosion of the
electrical wire runs will occur. In some limited cases the ink cartridge(s) just needs to be FIRMLY re -
