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 bridge rollers, accordion/tower infeed/exit rollers, and the
fold rollers in the crossfolder.
• If not, there is no ac power connected to the folder, or there is a jam condition, in which case the
location of the jam should be indicated on the control panel.
• If there is a jam condition, clear it as described on pages 2-6 and following, then reset the system
to restore power (see below).
• If the folder remains inoperative, and ac power is connected, check the fuse(s) in the power entry
module.
• If the problem lies elsewhere, request service technician assistance; or, if you are a specially
trained operator, remove the crossfolder rear panel and check the fuses on the power printed
circuit board located on the floor of the accordion folder.
2. Select the desired packet style. See Fold Selection below.
3. If you wish prints to exit the folder as flat sheets, select STACK to divert prints up through the tower
onto the stacking surface formed by the accordion folder lid.
The manual infeed rollers and
the stacker outfeed rollers at the rear of
the tower rotate continuously when the folder is running. In the stacking
mode, with unfolded prints accumulating on top of the accordion folder,
take care not to allow prints to be backed up into the infeed roller. This
will cause a serious jam condition. Prevent it by making sure the
accessory plate closes off the in-feed slot when you are not hand feeding
prints.
Fold Selection – Host controller
The fold selection methods available depend on the level of integration between folder, printer and printer
controller. In most cases the folder will be part of an integrated system and the desired fold program will
be selected at the host controller (See the operator’s guide(s) for the host system). This method of fold
selection can be overridden by changing the Communications mode.
Choices are listed in the Communications mode sub-menu on the control panel (first select System
Menu, then Communications mode).
NORMAL mode – integrated system
In the NORMAL mode, the folder operates under the control of a host computer, typically the Printer
Controller. Any of the supported communications protocols may be used to select fold programs, and
control the folder in shutdown and job recovery functions. The folder uses sheet size information provided
by the controller to minimize the number of compensating panels in bookfold-style programs. With the
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.
