Most toner cartridges in laser printers can be refilled, but some have refill holes while others require a hole to be made. It’s important to choose the right toner and follow instructions carefully to avoid damaging the printer or voiding the warranty. After refilling, calibration and resetting the page counter may be necessary.
There are different styles of toner cartridges used in laser printers, but you can refill most of them in similar ways. The toner in a laser cartridge runs out over time as you print, and you can replace the cartridges to get more toner into the printer. There are some toner cartridges, however, that are easily refilled rather than simply replaced. These typically have a refill hole that you can open to refill them, although doing so without proper training can create problems and potentially void the warranty on your printer.
Removing the cartridge
One of the first things you usually need to do to refill a toner cartridge is to remove it from the laser printer. Read the instruction manual that came with the device to determine the best way to remove the cartridge from it. This is usually quite simple, although you may need to push a release button or move a lever that normally holds it in place. You should also be careful of any toner on the outside of the cartridge, as it can easily stain clothing and the area around the printer.
Cartridges with refill holes
Some toner cartridges are designed to be easily refilled, often having holes into which toner can be poured. These holes are usually clearly visible on the cartridge and typically have a plug or cap that you can remove. Refill kits deliver toner in small bottles that include funnels or narrow tips, making it easy to place the tip into the refill hole without spilling it. The toner itself is such a fine powder that it moves like a liquid and can be easily poured into the cartridge.
Make a refill hole
There are also toner cartridges that do not have refill holes, as they are not designed to be refilled, only replaced. You may be able to punch a hole in such a cartridge by using a hot object to melt its plastic case. Some refill kits suggest doing this, but you should be very careful doing it. Such changes are likely to void any warranty you have on a printer cartridge, meaning you’ll have to pay for a replacement cartridge if you damage it. Improper hole placement can also cause toner to leak inside the printer, causing damage that may not be covered by your warranty since the hole you created likely violated it.
Choose the right toner
When refilling toner cartridges, it is important to choose the right type of toner for your printer. There are guides you can follow when ordering a refill kit to make sure the toner is compatible with your machine, and the manual that came with your printer may also tell you which toner to use. If your printer manufacturer sells toner cartridge refill kits, it might be best to use one of these to make sure you get the right toner and equipment for your hardware. Once the cartridge has been refilled and the bore sealed properly, simply replace it in your machine as directed in your owner’s manual.
Calibration and reset of the counts
Many laser printers need to be calibrated properly, and the toner cartridges inside them need to be aligned before printing. After refilling and replacing the cartridge, be sure to perform all proper setup procedures to ensure clean, aligned printing. There may also be a page counter on the cartridge that needs to be reset to tell the printer that the toner has been replaced. Your device’s instruction manual should tell you how to do this.
