Unfortunately, Primera cannot replace Edible ink that is beyond its best by date or ink that is expired (6 months from open date). However, Primera will replace any ink cartridge that is defective: clogged or not recognized by the printer. Please contact tech support to troubleshoot.
Best By Date: Sealed cartridges are best for one year after the source ink's original manufacture date. The best by date is printed on the cartridge box.
FDA regulations require a best by date on the packaging. The best by date may be very close to your purchase date. Keep in mind,
expiration dates and best by dates have very different meanings. Expiration dates tell consumers the
last day a product is safe to consume. On the other hand, best by date
tells you that the food is no longer in its perfect condition from that date.
It may just lose its freshness, taste, aroma, or nutrients. The best by
date is essentially a quality indicator. Since Primera Eddie ink is
similar to food coloring, it has no nutritional value or taste to contribute to
the overall food product. So you can be assured that using the ink beyond the best
by date is safe as long as the ink is still sealed in its foil packaging.
