The interlock system is designed to prevent access to components capable of causing injury. Do not try to defeat any interlock by taping or otherwise artificially holding it closed.

Line voltage (115 or 230Vac) is present at exposed points on the accordion folder base frame (back of the power entry module, and at fuses on the power supply board). This applies whether or not the interlock circuit is intact. Access to these danger points is prevented by a plastic panel at the rear of the accordion folder, which must not be removed by other than a qualified service technician.

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 document exits the printer/copier, and turns off when the flow of prints ceases. There is no need to figure the fold pattern for each and every document, nor is it necessary to remember which packet types and sizes are possible with a given width of media. For example, with few exceptions, the folder can deliver an 8½” x 11” folded packet from any standard width metric sizes.

Each print is measured as it enters the 2750 Folder, which then determines the appropriate number and style of folds to produce the desired packet. The folder accepts any mix of prints, in random order. All prints other than A-size are automatically folded into the selected format, then stacked with the title block “up and out” (except for Z-fold packets, which exit title block down).

Main components of the Model 2750 Folder The bridge is pivoted at the rear, allowing the in-feed to be adjusted in height to match most engineering printers and copiers. It can also be tilted vertically to allow service access to the back of the printer/copier.

Power entry module / counter / communications port

The power entry module, with on/off switch and main fuse block, is located at the base of the right accordion side panel. Adjacent to the power entry module are the print counter and communications port, diagram below. The communications port is a DB9 female type receptacle, configurable for an RS232 or RS422 link.

After initial power-up, or upon the closing of a door or lid, the folder motors operate for a few seconds, during which time the folder microprocessors perform diagnostic test and check for jam conditions. On completion of these tests, the folder returns to the standby condition, motors stopped. (The folder automatically starts up when an incoming print is detected at the leading edge of the bridge.)

Handfeed

Pressing the Handfeed pushbutton 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

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 to a host controller and the display will read ONLINE. Fold selections are made through the host controller. Additionally the host coordinates shut down and job recovery functions. If a fault occurs, or an interlock is opened (e.g., by removal of a cover panel), the display indicates the problem's location. Additionally, the technician may use the display to list machine settings, review recent error conditions, and to actuate various motors and solenoids for setup purposes.

When the folder is not connected to a host controller, the fold programs available to the operator are shown on the display in groups of four, the current selection being marked with an asterisk.

Handfeed Pressing the HANDFEED button on the control panel activates the off-line folding system, allowing prints to be fed by hand into lower set of rollers at the rear of the tower. When the off-line system is active, the control panel displays fold choices which may differ from those used in on-line folding.

For hand feeding, the print must be image down, with short edge leading. Bookfolding is not possible with hand feeding.

Receiver Advance Pressing the green RECEIVER ADVANCE button advances the High Capacity Print Receiver (optional, except on Fold System 40) for easy removal of the folded prints. Pressing this button also resets the Receiver full counter. When the High Capacity Print Receiver is installed as an option the key cap is

replaced with a green one.

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.

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.

Automatic document diversion

In the event of a paper jam or power failure, a solenoid-actuated diverter at the input end of the bridge swings to the upper position, diverting documents to the floor,

Stacker/Handfeed

Pressing the Handfeed button on the control panel activates the off-line folding system, allowing prints to be fed by hand across the top of the accordion folder into the rollers at the rear of the tower, diagram next page. The tower also enables the flat-sheet bypass, or stacking function. This is selectable in the same way as a fold program on the control panel (press the button indicated for Stack). In the bypass mode, the stack diverter at the rear of the bridge is flipped down so that prints exiting the bridge flow through the tower instead of the accordion folder.

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 custom packets require different panel widths).

Standard accordion fold packet

Having measured the length of the incoming document, the folder system automatically performs a compensating fold at the end of the

sequence. The two final panels in the standard accordion fold are of the same width, the width being dependant on the amount of length compensation necessary.

Note that the compensating panels may be aligned with either left or right edges of the packet, depending on the combination of the selected panel width (S) and the overall length of the document. They are

2750 op#1 R3.doc 10-02 Page 1-6

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 selections range from ½” and 2” in ¼” increments.

Printfold Folders provide two complete sets of bookfold programs, Type F and Type B, which differ in their treatment of short documents ranging from the minimum length of approximately 16” (400 mm) through 30” (760 mm). The exact limits depend on the bookfold packet width (usually 8½” in the US), and the binding margin selected. The two programs give identical results with longer documents.

Unlike the standard accordion fold, the bookfold has compensating panels inside the pack. Depending on the length of the incoming print, there will be either two

or four compensating panels as needed to deliver the correct direction of top and bottom panels (in all but a few special cases, the top panel points to the right and the binding panel to the left).

Bookfolds, Type F (Favor “F”ront) In a Type F bookfold, priority is given to a full top panel measuring 8½” (US models) less the binding margin. The final, bottom-most panel extends to the left of the package to form the binding margin. However, the bottom panel may not necessarily be the full 8½“ unless the document is of sufficient length. The top panel is always

full width, usually 7½” in the US.

Bookfolds, Type B (Favor “B”ack)

In the Type B bookfold, priority is given to the final, bottom-most panel, which is always

full-width (usually 8½” in the US). All other panels are narrower than the final, thus providing a binding edge. The top panel is a full panel less the binding margin, provided the document is of sufficient length for both the top and bottom panels to be full size.

Type F bookfold packet The Type F bookfold gives priority to the top (front) panel.

Type B bookfold packet

The Type B bookfold gives priority to the bottom (back) panel.

Crossfolding – overview

The accordion folded document is transferred to the crossfold section, which performs either one 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 function for oversize drawings.

Two packet orientations Folded print packets come in two basic orientations, portrait and landscape. The portrait, vertical style is the more traditional, and is used almost exclusively in European and certain other non-US markets. Landscape, horizontal folding is increasingly popular, especially in the US, because the resulting packet is easier to file.

Two fold styles Printfold Folders are capable of folding portrait and landscape packets in either of two ways, Z-fold or Cfold, diagram below.

or two

cs&zs. cvs

C-folds handle easier than Z-folds C-fold packets can be filed with only one edge showing, and are therefore easier to sort through and retrieve. The Folder can be programmed for either Z- or C-folds, but some user surveys show a preference for the latter.

The Z-fold packet (otherwise known as a DIN-fold) is the more conventional, but it suffers from the disadvantage that it always has an outgoing flap of paper that snags on other documents. It can be awkward to retrieve from a file. Additionally, Z-folding is not possible with some document sizes and orientations.

C-fold packets, a feature exclusive to Printfold folders, handle easier than Z-folds because they sit in the file with only one edge showing, and can therefore be sorted through much faster.

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 original). This allows, for example, a D-size (22” x 34”) image to be printed on 34” wide media with a linear feed of only 22”, compared with the 34” feed necessary in the SEL orientation. LEL thus enables greater production rates. The downside of LEL, however, is in the restrictions it places on document folding programs.

The words “Landscape” and “Portrait” are the key to understanding what happens in the folder.

For SEL documents … Landscape means wide accordion panels, Portrait means narrow accordion panels For LEL documents … Landscape means narrow accordion panels, Portrait means wide accordion panels

SEL = standard feed direction

Image up, title block leading, short edge leading

LEL = non-standard feed direction

Image up, title block trailing, long edge leading

• The folder automatically determines orientation by first classifying media width from 22” to 24”, then measuring feed length

from leading edge to trailing edge. For this example, if

, e.g., the D/A1 group

the feed length so measured is less than 19”, the document’s orientation is assumed to be LEL. (Standard prints whose long dimension fits the D/A1 media group have short dimensions of 17” = ANSI D, 420mm = A1, and 18” = Architectural D.). If the measured feed length exceeds 19”, the document is assumed to be SEL.

• Note that the width classifying system recognizes a media width as belonging to a particular group. It doesn’t measure it specifically. This is not an issue with SEL fold programs, which are highly flexible, and can deliver neatly folded packets from practically all combinations of length and width

. LEL programs are less flexible, but are capable of equally neat folding provided the document size approximates a standard sheet in the dimensional group (ANSI, Architectural or Metric) for which the folder is programmed.

• 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 Page 1-9

• 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 dimension of bookfolds is 8½” x

11” overall, with a 1” binding edge of 1”. Other binding edge widths from ½” through 2” may be selected by the service technician.

• The maximum document length for bookfolding is 120” with 20lb (75 gsm) bond.

Width sensors at input end of bridge

Sensor status determines document width. For example, if sensor PS3 is activated and the others not, the width must be greater than 15½” and less than 21” (this implies 17”, 18”, or 420mm media widths). Note that the width classifying system is just that, no more. It recognizes a document as belonging to a particular group, but doesn’t identify it specifically.

Note: When communications with a host is enabled the folder receives media width information directly from the controller overriding the bridge sensing system. If the printer does not accurately record a roll width, the error will be delivered to the folder and may result an improperly folded document or jam.

2750 op#1 R3.doc 10-02 Page 1-10

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” what the document length. (Overall width of a metric bookfold is 210 mm.)

, no matter

• A crossfold section capable of making two folds in the same direction to create a re-entrant, C-folded

packet. The crossfold section can also be configured for Z folding (DIN packets). However, C-fold packets are preferred by most users because of their easier handling and neater appearance.

• An accordion folding section with built-in inverter to accommodate non-standard print orientations,

such as C-size or D-size sheets exiting the printer with long edge leading (title block trailing). By flipping the accordion-folded packet upside down before it enters the crossfold module, the inverter causes the title block to appear in the normal position on the folded packet.

• A by-pass system that feeds unfolded documents to a waist-high stacking surface on top of the

accordion and crossfold sections. Maximum stack height is approximately 1”, equivalent to over 200 sheets of 20 lb (75 gsm) bond paper. The tower also includes a convenient hand feed slot for off-line folding, located waist-high at the rear of the diverter tower.

• Communications connectivity to a host controller/printer.

Options available

• A remote keypad option that allows the folder controls to be sited near the scanner, or other system

component.

• An optional High-Capacity Folded Print Receiver that allows up to 175 E-size or A0 folded prints to be

stacked on an external conveyor. Note: This feature is standard on the Fold System 40.
