Cartridge Type
Genuine or OEM (Original) Cartridges Remanufactured Cartridges Compatible Cartridges
Description OEM stands for original equipment manufacturer, meaning the cartridge was made by the same company that made your printer. Original brand cartridges are very reliable and sometimes the only option if your printer is new to market or uncommon. Remanufactured ink is a genuine brand cartridge that has gone through one cycle of use. After use, the cartridge is recycled, acquired by a remanufacturing facility and put through a rigorous professional refurbishing process. During the refurbishing process the cartridge is disassembled, thoroughly cleaned and tested for quality. It's then carefully refilled, tested again and brought back to life. Buying remanufactured prevents one less cartridge from ending up in a landfill. A compatible cartridge is a brand new ink cartridge built by a manufacturer other than your printer. It's like buying the generic version of the genuine brand. Most are uniquely designed to differentiate from genuine cartridges. Despite any structural difference you may notice, the cartridge will still fit in your machine and print a full yield, just like the original brand.
Price Factors Many printer manufacturers follow the razor-and-blades business model which may result in higher priced genuine cartridges. Remanufactured ink is much cheaper than the original brand ink. It's far more cost effective to refurbish a previously used cartridge than create a new OEM from scratch. Compatible ink is much cheaper than the original brand. Compatible suppliers don't have to worry about the additional costs that hinder OEMs like new printers or firmware, which lets them keep prices low.
Quality Original cartridges work extremely well and are covered under a warranty by the printer manufacturer High quality remanufactured ink will match the quality of the original, but not all remanufactured ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results. High quality compatible ink will match the quality of the original, but not all compatible ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results.
What's the difference between ink and toner cartridges?
Ink Cartridges Toner Cartridges
Printer Type Work with inkjet printers Work with laser printers
Material Liquid ink Dry powder
How it works Inkjet printers use a series of nozzles that spray tiny drops of ink directly on the print suface Laser toner printers use static electricity and heat to bond dry toner powder to a page
Commonly used by Casual home users, small business and photographers Large businesses and schools
Number of Pages You Can Print A cartridge's page yield is the estimated number of pages you can print. Page yield is based on 5% page coverage. This means that the quoted page yield is based upon printed pages where only 5% of the page has been imprinted with ink. For example, a short memo has approximately 5% coverage. If you have a cartridge that has a yield of 500 pages, it can print 500 pages of that short memo. If you are printing letters, photos or graphics, your coverage will vary greatly and your page yield will drop significantly.
Cartridge Warranty and Shelf Life Most ink and toner cartridges include a warranty or "best by" date on their box. Remanufactured and compatible ink cartridges can last 12-18 months unopened, and toner cartridges can last up to 3 years.
Cartridge Care and Storage Only open a cartridge when you need it. Opened cartridges will eventually dry out, especially if the protective tape or clip has been removed. If you have an open ink cartridge around and would like to try and prevent it from drying out, place it nozzle side up in a plastic airtight tub. If your cartridge came with protective tape or a clip reapply both before storing. Place a damp cloth or paper towel in the tub, next to the cartridge and keep it stored in a cool, dark place.

We have an HP home office inkjet printer that has outlasted 3 computers already. The ink, if purchased at the local office supply store, would cost as much (or more) than a new printer! We are happy to have found 123inkjets! The remanufactured cartridges work fantastic AND they last longer than the "store brand" versions we have purchased in the past from the "office supply store"! I have recommened this company to friends and family. Definitely a great product at a great price!

I bought a new cartridge while the old one still had ink in it because the old one was smearing ink on the copies. I thought maybe the cartridge was bad. So I bought a new one, figuring that if the new one worked okay, the old cartridge was bad.

The new one is doing the same thing. They both have gobs of ink on the very bottom of the cartridge, the very bottom in the picture.

But when I opened the new one, I found it that way right out of the box. So it's not the printer causing it?

Comments about Remanufactured Replacement for Hewlett Packard 51645A (HP 45) Black Ink Cartridge:

i use the ink to print emails or receipts, they come out good enough for me since i am not using it for a resume no one is going to judge me by my ink. that being said it still looks pretty good and for the price it's even better. The only thing i had to do to get my printer to accept the cartridge was align it and the message went away. I've been using it for a week and no problems. So i will be ordering again when in need.

Comments about Remanufactured Replacement for Hewlett Packard 51645A (HP 45) Black Ink Cartridge:

I was ready to purchase a new Laser Printer (Black Only) for what new Black and Color Cartridges would have cost for my HP Printer.
My daughter suggested I try 123inkjets Remanufactured ink and they work beautifully.
Saved me the cost of a new printer, and I still have my HP - FULL COLLOR printer. I hope it will serve me for another 5 years.

Out of the 5 HP45 Ink cartridges 5 were defective, to the point where the printed circuit board etchings on the back of the cartridge were ripped apart.

We don't print a lot anymore, so why spend a lot on ink cartridges!

These re-manufactured cartridges worked perfectly and we received them sooner than expected. We will definitely buy from 123inkjets again.
