CARTRIDGE REFILL 90 DAY "EXPIRATION"
Regarding your recent inquiry about the 90-day cartridge refill expiration dates, these dates are the
official instructions for integrated ink cartridges (i.e. those typically found in 2-cartridge printer models
and that feature an electronic nozzle plate attached to base of ink cartridge). If you can comply with
using the cartridge within the 90 day window, you will be assured of standard quality. If y ou have
recently discovered you are beyond the 90 day period, you should proceed with using the cartridge,
because it may work routinely.

CARTRIDGE LEAKING (ERROR MESSAGES & NO PRINTING)
Regarding your recent inquiry about the HP 56 cartridge error message and inability to print with your
HP Deskjet 5510, it sounds like the cartridge's nozzle plate has suffered 'delamination' and this is why
you are observing ink leaking at base of cartridge. The cartridge will likely be non-functional in this
condition and will need to be replaced with a new one*. Furthermore, the leaking has probably already
lead to an internal micro-electronic failure inside the cartridge. Inspect base of ink cartridge for cracks or
breaks – refer to last photo at the following link: http://inkjet411.com/?page_id=415
Please verify the age of the ink cartridge(s)....look at imprinted date on front (or back) of ink cartridge. If
this ‘warranty expiration date’ has expired, then potential cartridge failures can occur due to internal
corrosion, etc.
NOTE: Unfortunately, alignment pages and internal self test prints will usually print Ok even if the
cartridge is internally electrically damaged. Do not use these test pages as a proxy for determining
whether a cartridge is good or bad, only the ‘Tap 41/43’ diagnostic test report can yield this information.
As a temporary workaround, remove the suspect ink cartridge from the printer, and apply printer
power. This should place the printer into the 'single cartridge printer mode'....print jobs may then be
executed from the computer (only): For more information, refer to your printer user guide.
*Many cartridges 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. Refilled 'compatible' ink cartridges
are typically on their 3rd life of usage, or more...reliability of a compatible ink cartridge is therefore an
unknown variable.
