Please first 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.
Please perform the following corrective/diagnostic printer checks:
A. Ensure BOTH carriage/flex cables and BOTH ink cartridge contacts are thoroughly clean before
proceeding: http://inkjet411.com/?page_id=1519
