of the new HP's printers, i.e. several printer models currently sold at Costco, use either HP564,
HP932/933 or HP950/951 ink cartridges.

IPH PRINTER PROBLEMS – MOVE OVER TO REFILL FRIENDLY PRINTER MODELS
Regarding your inquiry, our bottom line suggestion is to move over to a more refill friendly printer
model (SEE REFILL FRIENDLY PRINTER MODEL SUGGESTIONS DOWN BELOW). Allow me to explain
why......
Most IPH ink cartridges (i.e. all 2-cartridge printer models) eventually do encounter problems or failures,
especially after their original ink is gone and they are re-used, and this is often unrelated to the refill
process (these same problems also occur with brand new ink cartridges from time to time). You
indicated you have an HP Photosmart C4680, you should be aware that this particular AiO printer is
'extremely sensitive' to any minor electrical fluctuations within the ink cartridge(s)...based on our Q1
2013 internal testing with HP60 ink cartridges which were returned for failures (i.e. "Cartridge Problem"
/ "Incompatible Cartridge" ink alert errors, etc), these same cartridges performed satisfactory in several
other printer models which use HP60 cartridges.
Now, generally the more severe printer error messages which result in non-permitted print operations,
represent a very small percentage of the mass experience (for this cartridge family), so please consider
the problem you previously encountered as being relatively rare with an ink cartridge that has only been
filled once or twice (~1-2% failure range).
The integrated ink cartridge electrical wire runs, at rear and lower sides of the ink cartridge, are
somewhat delicate and are susceptible to ink attack and subsequent internal electrical damage, which
can lead to premature failures. In addition, the older the cartridge the higher the chance 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. If the ink cartridge has an
expired warranty date (imprinted date on front of ink cartridge) then the cartridge age is typically over 2
years old and could be at significantly higher risk for potential failure when refilled.
NOTE: It is also common to have a marginally performing ink cartridge (which was performing ok before)
in the adjacent slot (i.e. color), then when a faulty cartridge is installed into the othe r slot (i.e. black),
both of the ink cartridge(s) then get flagged with electrical errors. This type of failure is quite rare with
an ink cartridge that that has only been refilled once or twice. Typically the ink cartridge's nozzle plate
suffers a break at one of the flexible circuit lines within the base of the cartridge nozzle plate...refer to

REFILL FRIENDLY PRINTER MODELS:
With respect to refill friendly printer models, it really depends on how much you print.
