Guide to purchasing staples for Canon printers and finishers.
Important Note: In order to purchase the correct staples for your machine, it is important you reference the FINISHER Model Identification Number.
DO NOT purchase staples based on the Canon copier model number alone. This is crucial because different finishers may use different staples, even if they are attached to the same Canon printer model
To locate the FINISHER Model Identification Number, firstly identify the finisher unit in relation to the copier unit. In most instances you will need to separate the finisher unit from the copier unit to access the model information, or you will find it on plate on the inside of the access hatch on outer edge.
