26.Click [Next] to start the NXT Multi Job Line Balancer using the current settings. To
review the settings, click [Back]. The line balancing process is started and the results
are displayed. Line balancing continues until the Line Balancer decides on the best
scenario.
27.Click [Save] to save the result of the line balancing back to the job. If this step is not
performed, then none of the results of the line balancing are reflected in the job.
28.After saving the results, then click [Exit] to close the wizard.

3.6 Optimizing
After balancing the line, the parts need to be distributed to the different modules and the
sequences for each module need to be arranged in the optimum order to minimize cycle
time. The optimizer is used to arrange the sequences in the best order. In addition to the
optimizer within Job Builder, there is another optional optimizer for optimizing different jobs
or sides. NXT Dual Production Optimizer is capable of optimizing two different jobs to run
on different lanes or two sides of a panel using two different lanes. For procedures on using
this optimizer, refer to the section Dual job optimizing.
3.6.1 Optimizing in Job Builder
The following procedures are used for optimizing one job only.
1. Select [Optimize] from the [Tools] menu to display the [Optimize Options] dialog box.
2. To optimize the feeder arrangement, select the [Allocate feeders] option. After
specifying the desired settings, click [OK] to display the [Select Machine] dialog box.
3. Select the desired machines, and click [OK].
4. Click [Yes] in the confirmation dialog box to confirm that optimization is to be performed
for the selected machines.
5. The [Optimize] dialog box displays. In this dialog box, the status of the optimization
process displays along with any errors. If any errors occur, click [Error Details] to display
further details. Click [Close] when the optimization process is complete.
Note: Once the job has been optimized, it can be transmitted to the NXT machine. It is not
necessary to generate recipes for the NXT.
3.6.2 NXT Multi Machine Optimizer
Generally, an NXT line consists of "one" NXT machine (made up of multiple bases). With
this configuration, line balancing is very simple and all of the parts are simply assigned to
the NXT machine. The parts assigned to the various modules is optimized and rearranged
during the optimization process. However, if the NXT line is comprised of multiple NXT
"machines", then use this software to line balance and optimize the job.
Job condition before using NXT Multi Machine Optimizer
The job must be in the condition below before using this software.
• The line must be already selected in the job.
• The basic configuration of the line must already be set (number and type of
modules and if not doing head or nozzle optimization, the heads and nozzles for
each module).
• All of the marks to be used must be assigned to the machines.
• All of the parts to be placed must be assigned to at least one machine. (This
software does not assign unassigned parts; it just moves assigned parts from
one machine to another.)
Procedure
1. Click the [Start] button, point to [Programs] > [Fuji Flexa] > [Optimizer] and then click
[NXT Multi Machine Optimizer]. The wizard starts and the first step displays.

Note: It is possible to start this wizard from Director by clicking the icon for it in the [Optimizer]
section of the icon bar.
2. Click [Next] to proceed to the next step.
3. Click the button with the three dots in the [Job] group box to display a list of the available
jobs.
4. Select the location for the job in the left pane and then double-click the job you want to
line balance and optimize to select it. The job is opened and the name displays in the
text box.
Note: The job cannot be opened if another program already has it opened.
5. Select the side of the panel to be line balanced and optimized.
6. Select any other options you want to use in this step and then click [Next].
7. Specify the settings for the conveyor in the [Conveyor Settings] group box.
8. If performing paired module production, then specify the desired settings in the [Paired
Setting Description
Optimizes the entire
NXT line
When selected, the entire NXT line is line balanced and
optimized. If option is not selected, then only the machine
selected in the [Line Configuration] list is optimized (if no
machines are selected, then the first machine is
automatically selected).
Support XPF Select this option if there are XPF machines in the line with
the NXT. By selecting this, the XPF will be considered
during optimization of the NXT machines.
Setting Description
Conveyor Mode This setting specifies the panel conveyance mode to be
used for production for determining optimization.
Board Flow This specifies the direction in which the panels flow
through the machine. This settings does not actually
control the direction in the machine but is used for job
related processing in Fuji Flexa.
Lane 2 reference
rail setting
This specifies whether or not the reference rail for the
second lane can move to different positions. If this is set to
"Fixed" the reference rail cannot move to different positions
and a setting must be specified for [Interval between lane
1 and 2 (mm)].
Interval between
lane 1 and 2 (mm)
This setting is only available when the setting for [Lane 2
reference rail setting] is "Fixed". This setting specifies the
location at which the reference rail for lane 2 will be fixed.
Target Conveyor This specifies the target lane on which the job will be
optimized. If set to "Lane 1", then the job is optimized with
the premise that the panels are to be loaded on lane 1.
