The Canon Inner Finisher L1 is a dedicated finishing module designed to integrate seamlessly with iR 2925i, iR 2930i, iR 2945i, and the iR-ADV DX C3900 series. It streamlines your document workflow by automating the final steps of printing, allowing you to organize large batches of paperwork without manual sorting. The unit features a dual-tray system with a total capacity of 545 sheets, consisting of a 500-sheet lower tray for various formats like A4 and Letter, and a smaller 45-sheet upper tray. This finisher offers versatile stapling options to suit different professional needs, including corner, double, and eco-stapling, as well as a staple-on-demand feature. You can secure up to 50 sheets of standard paper using corner or double staples, while the eco-mode handles smaller sets of up to 8 sheets. The device is built to accommodate a wide range of media weights from 52 g/m² to 300 g/m², ensuring it can handle everything from thin leaflets to heavier cardstock. Measuring 469 mm x 525 mm x 225 mm and weighing 9.1 kg, the unit fits compactly within the printer's footprint. For those who need to organize documents in binders, it supports the addition of an inner puncher unit, which increases the total weight to 13.3 kg and enables two, three, or four-hole punching. This makes it a practical choice for office environments where high-volume document preparation and filing are daily requirements.
