When preparing an ink cartridge for installation, only the yellow or blue tape seal from the top of the black or color ink cartridges should be removed. If the white label from the top or the clear film on the bottom of either ink cartridge is removed, the ink will be exposed to air and will thicken such that print head clogging and possible print head failure can occur. The cartridge should immediately be replaced to avoid potential damage to the printer. Do not remove the ink cartridge to check this and then reinstall the same cartridge.
