Device test
Accessible only to the Key Operator and technician
Device Test allows the Key Operator or technician to exercise independently several of the
folder’s key functions.

The crossfold stepper motors may be run at the same time as their related solenoids are
energized. For example, select
STP–Shift (L) to run the shift stepper motor in the left-hand shift
direction, then press +> as needed to display Shift Wheels . Now press the indicated button to
energize the shift solenoids with the stepper motor still running. Press +> again to return to STP-
Shift (L) . In a similar way, the pullback stepper motors can also be run at the same time as the
pullback solenoid is energized.
NOTE: Only two solenoids can be energized at any one time. Solenoids automatically time-out
after 15 seconds to prevent over-heating – which can also be caused by repeatedly re-energizing
them without a pause to allow cooling.
Fold Selection and Editing (Assign folds, Assign handfeeds)
Accessible to the Key Operator and technician
These functions allow the Key Operator to add/delete fold programs, and to modify bookfold
binding margins, etc.
Although there are approximately 70 different fold programs stored in the folder firmware, a given
user will be interested in only a few of them. The most popular programs have been collected into
groups, called Fold Banks, each containing up to 10 programs, see Section 9. The programs
included in each Fold Bank are targeted to the local conventions of a specific geographic market.
Select the appropriate Fold Bank number from the Parameters list under the System Menu. This
action loads the set of programs contained in the Fold Bank to NVRAM, which in turn provides a
program list to the operator’s control panel, and also makes the same list available to the Host
Controller. NOTE: This action loads the handfeed menu as well as the on-line folding menu. Fold
banks can only be changed by the technician.
Once the Fold Bank has been selected, the NVRAM program list available at the operator’s
control panel and the host controller may be edited. This allows programs to be added, or deleted
by the Key Operator to simplify the selections available to the user. But note that the Fold Bank
itself is in firmware and cannot be changed. Editing is confined to the list in NVRAM.
