Enhance the functionality of your imagePROGRAF PRO-2100 printer with this RU-23 Multi-Function Roll System from Canon. When installed, this system allows users to load a second roll of media into the printer or set up a bi-directional take-up unit. The dual-roll feeding mechanism can be used for fast swapping between two different types of media or just having two of the same rolls for high-volume jobs. The bi-directional rewinding method can help by letting users set up a take-up unit, and they will be able to choose whether the printed surface is on the inside or outside of the roll.
