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.

I have an HP Photosmart 2610 All-in-One printer. I have been very pleased with the quality of the LD cartridges ordered to date. However, When I replaced the black cartridge with one from my last order, it would not align. I tried another LD cartridge received in the same order and that worked fine. Does that mean the LD cartridge that would not align is defective? Is there a guarantee on the cartridges?


Our cartridges are covered 100% by our two years warranty from the original date of purchase. Please contact our customer service team at (888) 321-2552 to proceed with a replacement!


How many pages is this rated for? LD Remanufactured Replacement Black Ink Cartridge for HP 56


The HP56 or REMANC6656 will print approximately 450 pages.


Since I do not use my printer a lot, if I bought 3 cardridges, would the shelf life be too long and dry out before using?


The shelf life for these cartridges is 12-18 months; however, we recommend that you purchase cartridges that you will use within one year, as this is the extent of our warranty.


I would buy this product again.

Good cartridge!







Good product. Quick service



Very fast shipping and very low price


Ink quality appears to be same as HP. Very fast shipping and very low price.



LD stands behind their product.


I had some older print cartridges that suddenly stopped working. LD gave me some useful short term tips to make them work, but it didn't last. So they replaced the 2 year old cartridges without any problem.



I'll sure buy from Ink Cartridges again.


The cartridges work fine. They arrived in good shape and in unbelievable time. The big plus here is the company. I'm an old guy and not tech savvy. The customer service reps were patient, very helpful and everything they said would happen with my order did. I had everything mixed up and they straightened it all out. This was not my first purchase with this company and wont be my last. They are just great to deal with.
