  • Page 3: General Information

    General information There are four variants of the Printfold Model 2750 Folder, each accommodating a specific range of print speeds: XES Model 2753 XES Model 2755 XES Model 2757 Synergix Fold System 40 The Printfold 2750 Folder is self-programming, and fully automatic. It turns on automatically when a document exits the printer/copier, and turns off when the flow of prints ceases.

    Note: The folder assumes that all sheets have been removed from the receiver after the button is pressed. This action resets a software “print counter” used to determine when the receiver reaches a full condition. Page 1-3 2750 op#1 R3.doc 10-02...

  • Page 11 No matter what media width, document size, or orientation, the accordion folder will pass documents without folding unless the feed length is 3¼” greater than the selected panel width for accordion folding (210mm, 8½”, 9”, 11”, 297mm or 12”). 2750 op#1 R3.doc 10-02 PRINTER/ Document PLOTTER selfeed.cvs...

  • Page 13 Main features of the 2750 folding system • A length measurement system in the bridge between printer and folder automatically allows the accordion folder to deliver equal-width compensating panels, usually aligned with the trailing edge of the document. The same system ensures that the overall width of a bookfold is always 8½”, no matter what the document length.

  • Page 14: Operating Instructions

    The Printfold Model 2750 Folder is self-programming, and so automatic in operation that there is really very little for the operator to do. The folder turns on automatically when a document enters the bridge, and turns off (times-out), when the flow of prints ceases.

    Handfeed Pressing the Handfeed push- button switches the 2750 into hand-folding mode, displaying a modified list of programs. The print to be folded is fed into the rollers at the rear of the folder (image face-down, title block leading - centering is not important, but alignment is).
  • Page 16 Generic Folder Interface (GFI) the folder control panel displays the message ONLINE. With the FX interface the control panel displays ONLINE followed by the fold programs assigned to P1, P2 and P3. Except for Handfeed and Receiver Advance → (optional, except Fold System 40)), local 2750 controls are disabled in NORMAL mode.
  • Page 17 C-style crossfold). The fold choices are factory-assigned to specific fold banks from a set of over 100 programs resident in the 2750 firmware (fold bank examples: 0 = USA, 1 = DIN, 3 = France). Fold banks may be edited on-site at any time by trained service technicians.
  • Page 18 Manual document feeding In its normal “on-line” mode of operation the 2750 automatically processes documents passed from the printer. The 2750 also allows off-line operation, accepting hand-fed documents for folding. Because the width measuring system in the bridge is inactive when the folder is off-line, hand folding has limitations which do not apply to on-line operation: •...

  • Page 33: Section 2: The Crossfolder

    If only one crossfold is called for [2], the lower crossfold blade acts simply as a diverter, pushing the descending packet through the lower crossfold fold rolls, and then out to the crossfold receiving tray at left (viewed from the rear of the crossfold section). 2750 op#3 R3.doc 10-02 Packet shifts left-right...
