When you buy a printer HP 42A toner, you probably assume that it contains new toner, that it hasn't been improperly packaged, and that it will work correctly with your printer. However, mistakes happen--cartridges are accidentally opened or jostle too much during shipping, or careless coworkers could ruin a cartridge while putting it into storage. It's a good idea to get into the habit of inspecting printer toner cartridges on a regular basis, particularly before you install them into your printer. Knowing the signs of a low quality cartridge can save you a lot of money in printer repair and in toner costs.
The first thing to do is to look at the packaging of the printer HP CF283X. Make sure that the package matches up with the model number of your printer. If it doesn't, don't try to install it, even if the model number listed on the cartridge packaging is only one number off. Slight differences could mean that your cartridge contains toner that won't work well with your printer, so it's always important to buy compatible cartridges. You should also look to make sure that the package of the toner cartridge isn't torn or damaged. Check the toner cartridges' expiration date, too; this is sometimes listed on the outer packaging, but occasionally it will be on the foil inner packaging of a printer toner cartridge. Expired printer toner is no good, as it stands a better chance of clogging the print heads. Using an expired printer toner cartridge could lead to damage for your printer.
The next step in inspecting printer toner cartridges is to look at the unit itself and make sure that it isn't leaking any amount of toner. Look for cracks or splits. Most cartridges have a piece of plastic that must be removed before the cartridge is used, so check that this piece of plastic is intact and carefully remove it according to the instructions included with your printer toner cartridge. If the piece of plastic is missing, don't use the toner. It may have dried up due to the missing component, or it could be an indication of a defective cartridge.
If you notice any problems when inspecting printer toner cartridges, immediately call the store that sold you the toner or the manufacturer. There's often a number for customer concerns listed on the back of each cartridge's box. You should be able to receive a refund from any reputable printer toner manufacturer as long as you keep the original packaging and receipt on hand, and if you thoroughly inspect each cartridge before using it, you can replace defective cartridges without paying.
