Page 49: Using Specific Paper
Keep the volume of paper stacked in the paper feed tray to a minimum. A general guide is about half the height (about 25 mm/0.98 inch) of the paper feed guides. If the volume of paper is too large, the weight will cause the paper to adhere together, making peeling off difficult, and occurrence of two sheet feeds. Perform the operations in Chapter 2 “3-1. Selecting paper size” (p.20) to “3-8. Performing folding operation” (p.26). • Paper feed pressure adjustment lever DF-870: Set to [3]. If paper mis-feed has occurred, raise the paper feed pressure to [4] or [5]. DF-850: Set to (thick paper). • Separation pressure adjustment dial (DF-870 only) Set to [2.5]. When two-sheet feed has occurred, raise the separation pressure by [0.5] scale points at a time. Copyright © 2018 Duplo Corporation All Rights Reserved... -
Page 50: Rough Paper, Recycled Paper
If the processing speed is high, it could result in paper wrinkling or abnormal folding. • Set the paper feed pressure to low. If the paper feed pressure is high, it could result in two-sheet feeds. 5-3. B7, A6 size paper (For EU) The B7, A6 size paper can be processed under the following conditions. Paper stacking orientation: Vertical stacking Folding form: Single fold There are limits to the folding form depending on paper quality and paper size. If paper is small and light, a high processing speed could result in chaining (hooked feeds). Keep the processing speed as low as possible. Adjusting Misalignment Folding misalignment consists of two types, "up/down direction misalignment" and "left/right direction misalignment." Moreover, in addition to that, factors such as paper characteristics, etc., can also lead to "abnormal folding." Misalignment of the folding position can occur, based on the usage environment (temperature, humidity), paper quality, paper thickness, paper grain direction (vertical, horizontal), cutting precision, and print condition, etc. Copyright © 2018 Duplo Corporation All Rights Reserved... -
