On most cartridges, the date appears on one of the side flaps, but depending on the model, it might appear across the front of the cartridge. The number you are looking for begins with one or two digits, followed by a letter and a series of other numbers.
Find the year by looking at the first number of the code. For example, if the number is 12, then the year of production was ; if the number is 6, then it was manufactured in Identify the month of manufacturing by translating the letter after the first set of numbers.
Instead of using the first letter of each month, HP identifies each month using the alphabet -- the letter "A" represents January, "B" indicates February and so on see Tips. Identify the next numbers in the series to find the day of manufacturing.
We already know that if you started to use the ink you need to keep it working, but how long do ink cartridges last if not used? Does printer ink expire if unopened? Shelf life of printer ink in most cases is approximately two years. After that time there may be problems with the cartridge.
The sponge designed to deliver ink to the printheads can dry out. The ink can begin to separate and turn to sludge. After two years, even ink cartridges that are stored properly can get dicey. That being said, manufacturers like Canon claim that as long as the airtight seals are not damaged, their ink cartridges are safe to use even after several years in storage.
Making shelf life of ink cartridges longer is simple. If your cartridges are unopened, store them properly to get the longest life out of your ink:. If your cartridges are already installed in your printer, the best way to prevent your ink from drying out is to use your printer. Print a page in color once a week to prevent installed ink from drying up and clogging your printheads. All this will help to make printer ink last longer maybe even beyond the ink expiration date if any.
Refilling can be difficult to do correctly, and is often messy. Plus, in order to get the longest life from your refilled cartridge, you need to use it right away. New OEM ink cartridges are vacuum-sealed in airtight packaging to prevent them from drying out.
Refilled cartridges have no such protection. Your best bet is storing your refilled cartridges, nozzle side up, in airtight sandwich bags. In theory, a refilled ink cartridge should last six months before it dries up, since the ink is fresh. But in practice, refilled ink cartridges tend to dry up much faster than that , often in a matter of weeks, since they lack protective packaging.
Buying remanufactured ink cartridges adds to the confusion of cartridge expiration dates. A third-party — or sometimes the original manufacturer — will clean, recondition, and refill these cartridges for resale. Remanufactured cartridges DO come in protective airtight packaging and have a shelf life of two years.
However, the original expiration date remains on remanufactured printer cartridges, which creates confusion. Since it takes a while for ink cartridges to be used and recycled, it is not uncommon to find remanufactured ink cartridges with expiration dates that are several years old. It does not apply to the fresh ink inside your remanufactured ink cartridge. Remanufactured ink cartridges should be good for two years from the time of purchase.
Keep your sales receipt! Pages will come out faded, blotchy, or completely blank. Is there a way to tell if your ink cartridge expired just by looking at it? No, you need to install it in the printer to see if it works. If gunky old ink clogs your print heads, read about printer maintenance here. What happens with expired ink cartridges after they expire? They violently explode, leaving terrible, burning wreckage throughout your office space! Some people will get ink cartridges refilled in an effort to save money on printing costs.
Ink cartridges have expiration dates to indicate the date until which the printer ink will perform at its optimal level. Once the expiration date has passed, the ink no longer produces the same way it was designed to. With air working its way into the cartridge, it can dissolve into the ink carrier or the ink itself can become sludgy which goes on to clog your printer and print head and produce crappy prints. No other HP printers use ink expiration dates. If the model supports overriding the expiration date, the printer typically provides a popup alert asking if you want to ignore the expiration date of the ink cartridge and print anyway.
