How do I change toner cartridges?

Changing a toner cartridge is basically not a witch's work. However, there are a few points you should watch out for to protect your printer and your environment.

How can you tell that the toner is empty?

As a rule, the printer itself informs the user that the toner cartridge is empty and needs to be replaced. If this is not the case, the printed image will indicate that the ink is slowly fading or that unwanted gaps are appearing on the paper. There is no need to worry, because unlike inkjet printers, toner printers will not damage the print head if there is a lack of dye. This may be the case with printers that use ink.

How do I change a toner cartridge?

Some printers have an integrated guide (see cover) that tells you how to change the toner. This should be followed properly.

It is best to change the toner while the printer is not active. To be on the safe side, wait until the printer has cooled down and stop the power supply. So do not change the printer immediately after printing, switch off the printer and disconnect the power plug. Then open the device and pull out the old cartridges. It is advisable to avoid contact with skin, clothing and all objects. Disposable gloves are used for optimum protection against harmful substances.

Before using the new toner, it is recommended to clean it. Please read the instructions enclosed with the toner. Furthermore, in order to distribute the powder optimally, the print image can be embellished by gently shaking the toner cartridge.

Then insert the new cartridge the right way round. Do not touch the electronic contacts of the memory to avoid damaging the toner. Also the drum inside the printer should not be opened and carefully bypassed. Doing so may cause permanent damage to the printer and deteriorate the printed image.

When the toner is applied, close the cover and reconnect the printer to AC power.

How do I dispose of the old toner cartridges in an environmentally friendly way?

The manufacturers of the respective toner cartridges are obliged to take back the used cartridges free of charge. There are also companies that specialise in refilling old toners and then reselling them. Normally it is also possible to dispose of the toner in electrical markets or in the local recycling centre in containers provided for this purpose.
