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.

Comments about LD Refill Kit for Canon PG30 / PG40 / PG50 Black Ink:

I purchased this previously it is the easiest cartridge refill kit I've used. Do according to instructions and you should have no problems. Remember to inject the ink slowly and do not overfill. I will definitely purchased again when I need more ink. Excellent quality , makes ink refills affordable for a person on a small fixed income.


Doesn't work

Comments about LD Refill Kit for Canon PG30 / PG40 / PG50 Black Ink:

I bought this kit to refill my LD-RFK004B cartridges which I also purchased from 4inkjets. Refilled as per instructions, it will not print. I "cleaned and deep cleaned." but still nothing printed.


Just like OEM

Comments about LD Refill Kit for Canon PG30 / PG40 / PG50 Black Ink:

I use the RFK004B (Blk) and RFK013C (Color) to refill my Canon MG2520 cartridges and four of the five reservoirs on the MG5220. The MG2520 cartridges require accurate fluid measurements so I drain the master cylinders into a well marked syringe. The reservoirs of the MG5220 can be visually monitored and I fill directly from the big cylinders with a needle.

Good Product - Recommended

By Ink Buyer

Comments about LD Refill Kit for Canon PG30 / PG40 / PG50 Black Ink:

I have previously used a LD refill kit for the colored ink cartridge in this printer, after having a bad experience getting cartridges refilled at a Big Box store. So, when it came time to refill the black cartridge, LD was the obvious place to go.

Now lots of companies can sell you ink that will work. With LD, it's not only the ink, but the ink packaging and dispenser that are top-notch. Someone sat down and actually thought the problem through, and came up with a precision micrometer-like method of metering the ink into a cartridge. Very clean, very easy.

And they're not stingy with the ink - there's plenty. Enough for a half-dozen refills, at least.

Bottom line: these products highly recommended!
