Chapter 1 INTRODUCTION General information There are four variants of the Printfold Model 2750 Folder, each accommodating a specific range of print speeds: XES Model 2753 Print speeds up to 5 ips (120 mm/s) XES Model 2755 Print speeds up to 6 ips (160 mm/s) XES Model 2757 Print speeds up to 8 ips (200 mm/s) Synergix Fold System 40 Print speeds up to 10 ips (250 mm/s) The Printfold 2750 Folder is self-programming, and fully automatic. It turns on automatically when a do

Main control panel The main control panel is located on top of the tower section of the accordion unit. It comprises five push buttons for fold selection and service-related functions, a four-line x 20-character display, and additional push buttons controlling optional features that may or may not be installed. All control functions other than fold selection are password protected to prevent accidental reprogramming by non-trained persons. In normal operations the folder will be connected

Bridge The bridge is the link between printer and folder. Its main functions are determining the media width on which the incoming document was printed, and providing the means for measuring length of the document. It also signals the in-feed system to accelerate once the document has left the printer, the purpose of this being to increase the separation between one document and the next. This allows the folder to accommodate high-speed printers with small inter-copy gaps.

Accordion folding – overview Standard accordion fold In the standard accordion fold, all panels other than the final compensating fold are of the same width. The final or compensating fold of the standard sequence is positioned to give two equal-width panels, always narrower than the preceding ones unless the document length is an exact multiple of the selected panel width. Typical panel width selections for non-bookfolded documents are 210mm, 8½”, 9”, 11”, 297mm and 12” (bookfolds and c

always narrower than the panel width unless the length of the document - as measured automatically by the bridge and in-feed system - happens to be an exact multiple of width S. Bookfolds (accordion folding with binding edge) For bookfolding, the accordion fold sequence is designed so that the left hand edge of the bottom panel extends to the left of the pack. The “binding margin” thus formed, typically 1” wide in the US, may be punched for filing in a binder. Other binding margin selection

Crossfolding – overview The accordion folded document is transferred to the crossfold section, which performs either one or two crossfolds depending on the media width (this being the longer dimension of the accordion fold). Crossfolded packets are delivered to a receiving tray at the side of the folder. The crossfold section may also be programmed from the operator’s control panel to eject the accordion-folded document to the rear receiving tray without further folding – an automatic fun

Key facts about fold programs • Orientation of the document as it enters the folder is important! • The standard document feed orientation, SEL, is defined as “image up, title block leading, Short Edge Leading”. • The “other” orientation, LEL, defined as “image up, title block trailing, Long Edge Leading”, is increasingly used in electronic printing installations having the ability to rotate images in software (unlike analog machines, in which the copy orientation is established by the or

• The accordion folder has a capacity of 20 panels of 20lb (75 gsm) bond, less with heavier media. With a panel width of 12”, this allows a maximum foldable feed length of 240”. Accordion folding ceases at panel number 20, and any trailing portion of the document is passed unfolded. • The maximum number of panels of 20lb (75 gsm) bond that can be accordion folded and crossfolded is usually 12, corresponding to a document length of 144” with 12” panels. • • The standard dimensio

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. (Overall width of a metric bookfold is 210 mm.) • A crossfold section capable of making two folds in the same direction to c

Chapter 2 OPERATING INSTRUCTIONS After installation ... Your Printfold installer will have demonstrated how the folder operates with your printer or copier, showing how the bridge can be pivoted vertically for access to the rear of the printing system, and also how, in the event of a folder jam, documents are diverted to avoid a build-up of paper at the printer exit.

If you inadvertently leave the fold display mode, as in the above example, you will be in one of several password-protected modes not normally accessible to the operator. To return to the fold display mode, press MORE as many times as it takes to present “Quit” as one of the display options, then press the appropriate button. Start-up 1. Turn on the Power switch on the power entry panel (press I). You should immediately hear the sound of motors and rollers running - these are the bri

The communications protocol in effect is determined by the firmware installed in the folder, and by the Host parameter in the Parameters menu. USE KEYPAD FOLDS mode – integrated system In this mode the control panel on the folder is used to select the fold program, overriding fold selections made elsewhere. All other communications features remain in effect, including shutdown and job recovery functions, and sheet size transmission. In the USE KEYPAD FOLDS mode, the control panel dis

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: • Bookfolding is not possible. • The final fold in the on-line process delivers two equal-width panels.

There are two parameters available to the service technician to customize the hand feeding process to suit individual operator preferences: • Handfeed delay: Determines the amount of time that the infeed sensor is covered before the tower rollers pull the document in. The delay is selectable from 0 through 10 seconds (2 seconds is the default condition). Some users prefer a longer delay to allow more time to square up the document. • Handfeed ramping time: This is the “oops” provision.
