The Standard Horizon HOF-30 High-speed Sheet Feeder provides production speed and flexibility for digital print environments. The HOF-30 feeds pre-collated digital output at up to 27,000 sheets per hour, and can be combined with Horizon SPF-20/20A or SPF-30 class saddlestitching systems. By adding a collating tower, the finishing system can effectively serve print shops that perform both offset and digital printing under one roof. A mark reader also enables the HOF-30 to handle personalized, variable sheet count documents with integrity and verification. An optional cover feeder provides additional production flexibility.
