Most types of printers that use ink, such as Canon printers, use ink cartridges that have a chip installed, whose use is to indicate the level of ink left in the cartridge. A replacement ink cartridge may need to have the chip from the original cartridge installed before it can be used in your printer. You can change the chip on ink cartridges by first saving the old ink cartridge that has the chip you will need to install on the new cartridge.
Locate the chip in the old ink cartridge. The chip will be located at the bottom edge of the cartridge, on the angled portion of the clip.
Remove the tops of the plastic tabs that are used to secure the chip to the cartridge, using the end of a utility knife. Place the blade of the utility knife under one of the plastic caps end gently pry up.
Repeat the previous step to remove the other cap, and then lift the chip from the cartridge.
Locate the two plastic prongs that are used to secure the chip on the replacement cartridge.
Apply a small amount of Blu-Tack adhesive to the backside of the chip. The blu-tack will help to keep the chip secure to the replacement cartridge.
Place the chip onto the two plastic prongs and press down gently, until the chip falls into place over the prongs.
Insert the cartridge into the printer to complete the project.
Use the end of a pen to push the prongs together so the chip will fit.
Using the wrong type of chip with the replacement cartridge may cause the printer to not recognise the cartridge. Changing the chip on an in ink cartridge may cause the ink level monitor to no longer work properly.
