Morgana DocuMaster MFC - Service Manual 11
1. Introduction - Machine Overview
3. The GUI (Graphical User Interface): The GUI control panel has an 8.2" colour
touch screen that the operator uses to control the MFC and online bookletmaker
system.
Note: the touchscreen has a power save function. If it is not
used for a period of time it automatically dims. After an
extended period it is turned off. Touch the screen to turn it on.
The GUI is attached to the LH side of the MFC in the same way as the side covers and is
con
trolled by the CPU inside the DRV module. A touch sensitive START button and a touch
sensitive STOP button on the bezel above the screen are used to operate the MFC.
4. The Feed Bins:
The feed bins are loaded with paper in centre-referenced trays.
Multiple bins can be electronically linked together for continuous running and the
bottom two bins can be set to insert cover stock. The feed bin takes an individual sheet
from the top of the paper stack and moves it through the built-in SMART detection
system, which senses miss, double, trailing and jam errors. A separation air supply is
connected to all bins and simple controls on each feed bin let the operator adjust the
feeder to give an accurate sheet feed.
The standard MFC feeder configuration is:
• 3 suction feed bins
• 1 friction feed bin.
Note: The friction
feed bin must always be positioned directly
above the creaser module where it can be used to insert
heavier weight cover-stocks up to 300gsm.
An alternative configuration that is available upon request is:
• 4 suction feed bins.
Note: This configuration would
normally be used if a
customer's stocks were unsuitable for a Friction feed system
and if he only used stocks up to 240gsm.
5. The Creaser Module: T
he creaser module is installed below the feed bins and can
be programmed from the GUI to crease covers, centre spreads or even all of the
sheets in a booklet.
To compensate for sheet skew during the feed
process, the creaser control system
uses an array of sensors to register the lead-edge of each sheet as it enters the
creaser module. The creaser control system automatically sets the creaser blade-set
to be the same as the skew of the sheet, which makes a perfectly square crease every
time. This mechanism is known as the DynaTilt.
The crease pressure is infinitely adjust
able and uses two simple mechanical
adjustment cams to produce up to 6 metric tonnes of pressure between the crease
blade and the crease matrix.
6. The Gathering Area:
The gathering area is part of the MFC's base. Paper is put into
the gathering area through a neutralising ion field that is generated by an integral static
elimination bar. The sheets are controlled with a combination of conveyor guides and a
variable pressure air knife to make sure that they gather neatly and remain in the
correct order.
