The FD 4170 Cut-Sheet Burster is the ideal finishing solution when multiple forms are printed on one page. Direct from a laser printer to the FD 4170, pre-perforated forms are automatically burst at perforation and stacked sequentially at speeds of up to 140 sheets per minute. No more cut sheet bursting by hand! Features include 5-level speed control, LCD counter, pro-programmed settings for 11", 14" and 17" paper, adjustable side guides, and last job memory.
