Generic Printer Ink

Posted In: Articles by Professor Ink

If you have been shopping around for printer supplies lately, you may have noticed terms such as generic, compatible, or remanufactured cartridges coming into play. You have found that these generic, compatible, and remanufactured cartridges are generally much cheaper then original printer ink cartridges, however how do you know if they are safe? Will they void your printers warranty? Will they damage your printer? Will the prints look as well as the originals? Read on to find out what you need to know when shopping for generic printer ink cartridges.

First off, lets find out the difference between original, OEM, generic, compatible, remanufactured, and refilled kits. Original cartridges are the easy one, they are the printers brand of cartridges that you see on the shelf at many retail stores. Printer manufacturers always tell you that you should replace your printer ink or toner cartridge with the original for best results. What they are not telling you is that the replacement cartridges they sell often can make up over half of the companies entire revenue! This makes sense when you factor in how cheap you can buy a printer for, but when you go to buy the cartridges, you find the prices are outrageous. OEM means Original Equipment Manufacturer, and simply is just a fancy way of also meaning original brand cartridges.  Compatible cartridges can be for either ink or toner and are manufactured completely new including a new plastic cartridge body, new chips, new drums , new rollers, new fuses, new everything!  For the entire aftermarket of compatible and remanufactured cartridges generally see’s an average of 1-3% defective rate for these cartridges.  Consumers can generally expect savings of 50% or more when purchasing compatible cartridges.  Remanufactured are simply that, remanufactured.  A remanufactured cartridge starts out as an original cartridge and is then used until it has been depleted.  These empty original cartridges are gathered by various different methods and are then fully inspected before and after the remanufacturing process begins.  Remanufacturing processes can vary in levels of detail depending on the company, but to ensure the highest quality of output, the products will have many pieces replaced, new sponge or drum installed, new ink or toner, and finally tested to ensure the cartridge is working properly.

Generic printer ink has saved companies and individuals hundreds if not thousands of dollars over the lifetime of their printers.  The best part is that your printers warranty will not be compromised due to using cartridges other then the original expensive ones.  For more information about protecting your printers warranty please see the Magnuson-Moss Warranty Act.

Now that you feel comfortable with the terminology and what to expect about the respective types of replacement printer ink cartridges, you should know that not all compatible and remanufactured cartridges are alike.  Just like many products, their are many different manufacturing or remanufacturing sources of printer cartridges and not all are created equal.  It is extremely important to purchase your replacement printer cartridges from a reputable seller who offers a warranty on the cartridges.  Please do not be fooled by extremely low prices on sites such as ebay.  Quality compatible and remanufactured cartridges can only become so cheap until their quality is at stake due to reducing prices.  Professor Ink does not sacrifice quality in anyway when sourcing compatible and remanufactured printing cartridges.  We understand how frustrating it can be when you need to print something and it doesn’t work.

If your Brother Laser printer has the “Drum” light on, this generally means one of two things. Either your drum needs replaced, since drums last about 20,000 pages, the occurrence of this many vary due to how often your printing, or the other option is that you have just replaced your drum and the light will not go away.

To reset the Drum light on your Brother Laser printer can vary slightly by model, however the general idea is the same.

For example, to reset the drum light on the Brother HL-5250DN laser printer, one should open the access bay to the toner cartridge and drum area, HOLD DOWN the “GO” button and you will see the lights on the machine light up one after another. Once all of the lights are illuminated you can then either replace the drum, or remove the drum and reinstall. Once you have completed these steps you will find that the drum light is no longer illuminated and you can continue printing like normal.

Other Brother drum light issues may be solved similar to the Brother HL-5250DN however some may require you to hold down the “GO” button before opening the access bay.

We hope this information helps you folks, and in fact, all replacement Brother Drum’s at Professor Ink come with a convenient manual on how to reset the drum light for your Brother Printer.

Posted In: Articles by Professor Ink

So your nice shiny HP Printer’s ink is starting to run low.  If your HP printer uses the 74 series black cartridge then you may have noticed shopping around that their is a model called HP 74, and HP 74XL.

Remanufactured HP 74XL

Remanufactured HP 74XL

XL as you would presume means extra large and simply has more ink inside the cartridge.  Here are the different page yields for these two cartridges:

HP 74 (Standard): Approx. 200 pages
HP 74XL (Extra Large): Approx. 750 pages

As you can see, when comparing the HP 74 vs. HP 74XL, the page difference is really quite astonishing.  Their is a catch those as with most printer cartridges, so you should be careful when deciding which cartridge to purchase.  Many printer ink cartridge manufactures will give an ink cartridge a shelf life or expiration date of generally 2 years.  Please note that this is a shelf life and not installed life.  Once the ink cartridge is installed, it is generally recommended to be used up in about 6 months or to print a page weekly to make sure the ink does not dry to clog the print head.  Knowing this now, you should decide if you believe you will print 200 pages over the next 6 months or you can print 750 pages over the next 6 months.  While the HP 74XL is a better deal per page, it won’t be such a great deal if you end up not using half of the ink and it dries out.

The original HP 74XL Black printer ink cartridge is sold at retail for about $34.99.  Professor Ink offers a remanufactured HP 74XL printer ink cartridge for only $15.97!  By purchasing a remanufactured cartridge from Professor Ink, you can nearly purchase a HP 74XL cartridge for the price of an original HP 74 standard cartridge.  All cartridges from Professor Ink come with a 12 month warranty against manufacturers defects.

We hope this article helped to clearly explain the HP 74 vs. HP 74XL and which you should choose for your HP Printer.
