On the following pages you will find our Octopus® refill instructions for all common printer cartridges. Often our instructions are supplemented by additional tips and extensive information on how to use our Octopus® refill equipment, our cartridge chips or alternative products such as Fill In™ cartridges. In some cases, there may be several procedures for one and the same result. Our instructions are sorted by printer manufacturer and cartridge name. You can also find the appropriate instructions for your product under the link "REFILL INSTRUCTION" directly on the respective product here in the online store.
