1.1.1 Controller Stand (P/N BK705-ST)
The controller stand (Figure 1-1) provides a clean method of housing the BK705
components and options (Figure 1-2). It is optional for Apollo systems, but mandatory for
all other technologies. It is also supported on four caster wheels to easily move the whole
controller around. It can house the computer module, a separate power supply module, an
Ink Delivery unit, and computer peripherals such as the monitor, keyboard, and trackball.
For increased flexibility and comfort, the stand also provides the ability to set the height
of the monitor as well as the position of the keyboard by adjusting it along the aluminum
extrusion rails. This can be done by loosening the mounting screws, repositioning the
monitor or keyboard tray, and retightening. A description of the range of adjustment can
be seen in Section 1.2.

2.1.3 Head Drive Circuit Board (HDC)
The Head Drive Circuit Board (Figure 2-3) generates the high and low voltage signal
required to fire the printhead and also regulates the printhead voltage. When the low voltage
signal is received by the HDC board, LED D1 turns on. When the high voltage signal is
outputted by the HDC board in order to fire the printhead, LED D6 turns on.

One HDC board is required for each 1250 printhead (1”) while two are required for a 2250
(2”). When a 2250 printhead is utilized, a dual HDC cable (9100510A) replaces the two
single HDC cables (9100197A) and a 12V wire from the 2250 Printhead umbilical is
connected to the 12V contact on the SSB board (Figure 2-4).

2.1.4 Lung Vacuum
The purpose of the lung vacuum is to remove gas from the ink which can form bubbles that
cause jetouts. The lung vacuum should measure approximately –23.5 inches of mercury (in
Hg). If the vacuum drops below 14 in Hg, there may be a loss in jets during printing. If a
large volume of ink is purged out at a given time, wait at least two minutes before printing in
order to provide time for the Lung Vacuum to remove trapped gasses in the ink.

Chapter 2 Controller Components Page 2-6
2.1.5 Ink Supply Line
The ink supply line controls the flow of ink from the ink container (located in the ink bottle
holder) to the printhead. The sequence of the ink flow from the container is summarized
below:
1. Ink starts in the ink container and is fed into the subcontainer.
2. The float switch determines if the correct amount of ink is in the subcontainer.
3. The peristaltic pump head pumps ink through the filter. If pressure reaches 20
psi, ink is released back into the subcontainer line through the relief valve.
4. The hydrophilic filter filtrates ink before exiting the inkwell.
5. Ink travels from the inkwell to the printhead through the umbilical.
6. The printhead solenoid valves open and close to supply ink to each printbar
individually.

2.1.6 Maintaining the Ink Line
In order to ensure optimum performance, it is important to replace the relief valve, filter, and
the tubing once every six months. In order to do this, refer to the following instructions:
1. Turn off the system and wear splash safety goggles and gloves before any
maintenance work is done. Use caution as ink lines can be pressurized.
2. Using a flat-head screwdriver, turn the peristaltic pump clockwise in order to remove
ink from the ink line between the pump and the relief valve.
3. Replace the relief valve. The arrow on the relief valve must point towards the
subcontainer line.
4. Replace the filter. Note that the filter used depends on the type of ink (See Appendix
B for the part number of the proper filter).
5. Replace the tubing in the peristaltic pump using the tool provided (Figure 2-6).
6. Ensure all lines are connected properly and are tie-wrapped on all fittings to prevent
ink leakage.
Note: It may be necessary to replace the tubing more frequently than specified above
(especially in the peristaltic pump). This should be determined by regularly inspecting the
tubing for signs of wear.
Figure 2-6: Installing Tubing in the Peristaltic Pump
Buskro Ltd. BK705 Ezejet Controller
Page 19
Chapter 2 Controller Components Page 2-8
2.1.7 Replacing the Ink Bottle
Once the ink bottle is empty and the ink level in the subcontainer drops, an ink low icon will
appear (Figure 2-7). At this time, a fresh bottle of ink should be installed.
Figure 2-7: Ink Low Alarm
Note: Ink must NOT be recycled by placing used ink back into the bottle. Not only can this
damage the printhead, but it may also contaminate the filter and result in the ink line
bursting due to backpressure.
Never use unapproved fluids with the system (including other inks) as this could cause
permanent damage to the system. For example, mixing Monet and Cezanne inks will
cause permanent damage to the system. Buskro is not responsible for any damage
caused by improper use.
2.1.8 Peristaltic Pump Head
The peristaltic pump head is responsible for pumping ink from the subcontainer to the
printhead. The number of strokes is controlled electronically by the proximity sensor
installed above the pump head and the gearmotor installed over the metal coupling. The
peristaltic pump head displaces a certain amount of ink per stroke. The arrows show the
direction of the ink pumping (Figure 2-8). The 12 VDC gearmotor drives the pump in a
counter-clockwise direction.

Chapter 2 Controller Components Page 2-10
2.1.9 Pressure Regulator
The pressure regulator controls the meniscus vacuum and the purge pressure. The meniscus
vacuum is responsible for maintaining a continuous negative pressure (-3.3 in Wg for 1250
printheads and –4.7 for 2250 printheads) required to prevent ink “weeping” (leaking out of
the head) and for creating a positive purge pressure (50 in Wg) to prime the printheads. The
pressure regulator generates the positive and negative pressures. In order to prevent ink from
being drawn into the pressure regulator, a hydrophobic filter is installed for each printbar to
stop ink from passing through. This filter is also used to filter air used when purging the
printhead. If ink enters the filter, it must be replaced.
Figure 2-9: Pressure Regulator (BK-PVM-700)
Note: If the meniscus pressure is too high, it can prevent proper firing of the jet. Air can also be
ingested into the ink causing jetouts. If the meniscus pressure is too low, ink can leak out
of the head and pool on the orifice plate, material or the transport base. It can also cause
misfires or jetouts.
If the purge pressure is too low, it may be ineffective in recovering jets. If the purge
pressure is too high, it will use more ink. It will also take longer to remove gas from the
ink which could result in jetouts.
If ink leaks from the printhead while the system is powered off, there is likely a leak in the
meniscus line or the solenoid is not closing properly.

2.2 Apollo Ink Delivery Module (IDM)
The optional Apollo IDM (Figure 2-10 and Figure 2-11) provides a higher capacity ink
supply for Buskro Apollo printheads. Without the IDM, the user is relying on individual ink
pens that only hold approximately 42 mL of ink each. By using the Ink Delivery Module, the
user is provided with a 350 mL supply which can supply up to eight ink pens simultaneously
(four inches of vertical print swath). The two available kits are 705-IDM4H-15NA (for
North America) and 705-IDM4H-15WD (outside of North America).
Figure 2-10: Apollo Ink Delivery Module
Figure 2-11: Apollo Ink Delivery Module on a BK705
Buskro Ltd. BK705 Ezejet Controller
Page 23
Chapter 2 Controller Components Page 2-12
Some advantages of using the Apollo Ink Delivery Module are:
1. Convenient Ink Management – The ink is distributed and pumped, both vertically
and horizontally, over a maximum of 15’ distance from an operator-accessible point
to all remotely located ink pens.
2. On-the-Fly Refill and Level Sensing – The replaceable 350 mL ink cartridge is
equipped with level sensing that alerts the operator when ink is low. This prompts
the user to replace the ink cartridge.
3. Common Ink Distribution – The Ink Delivery Module features a common manifold
that distributes ink to up to eight ink pens (the pens are the HP 45A “cartridges” in
the printhead). This ensures uniform ink filling to all pens which can reduce
individual failure. For example, if the user relies on individual ink pens, if one pen
runs out of ink before another (e.g. one pen might be printing a heavier part of the
layout), it may result in wasted pieces due to failed printing. When an Ink Delivery
Module is used, all pens are supplied by a single source to avoid this problem.
4. Reduced Intervention – The large 350 mL supply reduces operator intervention
during operation.
5. Front Panel Indicators – The Ink Delivery Module features a series of five indicator
LEDs. These LEDs indicate whether or not there is Power, if the system is Online
and ready to print, if ink is low, if ink is out, or if there is an error.
For more information on the Apollo Ink Delivery Module, refer to the BK-IDM-4H manual
or contact a Buskro representative.

2.3 Power Supply Module
The Power Supply Module (Figure 2-12) is a rack-mounted module that provides the
necessary power requirements for a given technology. Apollo uses the BK-PSM-4H while
Atlas and Aurora (Monet, Cezanne, and Renoir inks) use the BK-PSM-4A.

2.4 Field Connection Board
The Field Connection Board (FCB) serves as an interface and electrical isolation between the
controller’s internal circuitry and external equipment. The FCB has a number of inputs and
outputs. The inputs mainly deal with sensor signals (jam detectors, photo sensors, a shaft
encoder, and a cycle input) that are brought out on individual connectors on the connector
panel associated with the FCB. They are also available as a group on a single input cable
connector. The outputs are also brought out on a cable connector and provide relay contact
outputs for such functions as a stop signal to the inkjet equipment, control of a stack function
(to control the speed of a conveyor for stacking purposes), and a diverter.
When the Buskro controller is used with a standard Buskro base, all communications with
the base are internal through a ribbon cable and the connections on FCB are not needed.
The external connections provide a more general interface to allow the controller to work
with a variety of equipment that does not necessarily conform to Buskro’s standards. The
actual operation and connections to the board are discussed in detail in Appendix E.

Chapter 2 Controller Components Page 2-15
2.5 Datapath and Image Accelerator Card
The Datapath (Figure 2-13) and the Image Accelerator (Figure 2-14) Cards connect to the
motherboard through the PCI Bus and perform the following functions:
• When a Buskro transport base is present, interfaces with the Base Interface board or Base
control board to receive sensor inputs from the base.
• Where a Buskro transport base is present, interfaces with the Base Interface board or Base
control board to control the base and conveyor.
• Provides a communication port for control and monitoring of the “life” support elements.
• Receives configuration information from Compose IQ.
• Transmits status information to Compose IQ, the inkjet control software.
• Controls printhead firing sequence.
• Transfers image data via the data ports.
Each Buskro controller is equipped with either a Datapath or Image Accelerator Card.
Figure 2-13: Datapath Card with Expansion Board
The Datapath Card supports four data connections for printheads. An expansion board is
required to add support for an additional four data connections (for a maximum of eight
printheads).

Chapter 2 Controller Components Page 2-16
Figure 2-14: Image Accelerator Card with HeadIF Board
The Image Accelerator Card is a replacement for the Datapath card. It is a newer, faster card
with more features. For an overview summary of the differences between the Datapath and
Image Accelerator Cards, reference Table 2-3.
Table 2-3: Datapath and Image Accelerator Card Comparison
The Image Accelerator Card has the ability to diagnose itself to assist with troubleshooting.
It is able to test its internal memory, all inputs and outputs, and all the data channels (print
ports). This can be accessed through the Test / Diagnostics screen (Figure 2-15).

The Expansion Board is only used with the Datapath Card. It is used to add the capacity
for four more data ports (for up to four more printheads), allows for a second technology
to be added, and provides access to use the Tracking Board.
The Expansion Module is used to add the capacity for an additional four data ports for
systems utilizing the Image Accelerator Board. This kit is not required to add multiple
technologies or to access the Tracking Board as these features are inherent in the Image
Accelerator Card. To activate these features, the appropriate license option is required
(BKLI-OPT-CBO for multiple technologies and BKLI-OPT-TRK for Tracking).
2.6.4 Tracking Board (P/N BK-TRACK-1700)
By purchasing the Tracking option for the BK705, this provides users with the ability to
track each product as it travels through the system which is comprised of a series of zones
(e.g. inkjet zone, inserter zone, etc). It is also possible to track products through nonBuskro equipment. For more information, contact a Buskro representative.

For Atlas or Aurora systems, the tracking board can be ordered (BK-TRACK-1700). For
Apollo systems, the tracking controller (P/N BK705-TR) should be ordered instead of the
standard controller (P/N BK705). Since a tracking board assembly is required (P/N BKTRACK-1700), a slightly different computer assembly is needed. Instead of using the
integrated Apollo power supply found in the computer assembly of the standard Apollo
BK705, a separate power supply (P/N BK-PSM-4H) is used. In addition, the computer
module faceplate changes to support data connections in the front instead of the back. In
this configuration, the computer assembly is the same as the one used in the BK1705,
BK1710, and BK1720 controllers. Figure 2-17 provides a visual representation of the
differences.

2.7 Grounding
Proper grounding is essential for proper operation of equipment as well as for safety. If a
system is improperly grounded, it can result in an array of intermittent or even permanent
operational problems. In the case of the BK705 Controller stand, each individual panel is
connected together with a common ground using ground wires. The individual modules
also need to be grounded to the stand (e.g. computer or power supply modules) through
the available ground tabs or studs. It is also important to ground the controller to the
transport base. A ground stud on the stand is available to connect a ground wire to other
equipment in the system (Figure 2-18).

Chapter 2 Controller Components Page 2-22
When connecting to a ground stud, it is important to use a star lockwasher to cut into the
finish of the cabinet (Figure 2-19). This is because paint or finishes can act as an
insulator. It is recommended to use an AWG 12 or heavier green/yellow wire when
connecting the ground between machines.

3.1 Introduction
In general, Buskro print technology is designed to work with a Buskro controller equipped
with Compose IQ software. Compose IQ is a Windows® based application that controls
all operational aspects of a Buskro inkjet system. This easy-to-use control software
delivers powerful job setup, layout, production management, record control, diagnostics,
and reporting.
Compose IQ is a built-in package capable of supporting systems applications in which
machine control, data acquisition, print sequencing, and product tracking or a combination
thereof may be required. Essentially, the software provides the following rudimentary
tools:
• Product tracking and print sequencing
• Communication with reading devices or other controllers via the COM2 serial port
• Data output communication with other devices via COM3
• Machine control utilizing a PLC with communication via COM1
• Data acquisition and record retrieval in OCR mode
The software offers three distinct building blocks for the implementation of a system.
This includes client (slave) mode, OCR mode, and selective device control supporting
host mode (master) for data echo requirements. Figure 3-1 below illustrates the different
configurations:

3.2 Host/Client Mode
3.2.1 Client Mode
Client mode permits the controller to accept data directly from another controller (device)
via the serial COM2 port, and at the appropriate time, print out some or all of the data
based on the image layout. A number of baud rates and physical definition tools are
offered to tailor the controller to the physical delays of the system and provide a data
communication link with a host controller (device).
3.2.2 Host Mode
Host mode provides a means whereby a portion or all of the printed record data is output
on COM3 such that it can be acquired and used by a downstream controller/device. This
capability allows for the creation of distributed systems in which a number of printers can
be networked together and controlled by a host controller.
3.3 OCR Mode
The OCR mode functions in much the same way as the client mode with the addition of a
lookup and data retrieval process occurring prior to image creation. This capability
supports reading devices that send limited data via the serial COM2 port, representing a
key that maps onto a defined component of the data file such that a search will find and
retrieve the entire record corresponding to the key. As with the client mode, the resulting
record’s components are then printed out as defined by the image layout.

Chapter 3 Compose IQ Page 3-3
3.4 Selective Inserting Mode
Completing the suite of controller products is a selective device control operation. With
this, individual records are sourced from the aforementioned applications or the resident
database and subsequently queried prior to the printing operation. As a result, various
upstream and downstream devices can be actuated via a PLC based on the contents of
these records. Included with this is a data echo feature that outputs all or part of the
printed record on the COM3 serial port for communication with other downstream client
controllers. This creates a distributed network of printers.
PLC control and communication is enabled through the COM1 port where a number of
virtual input/output points are transmitted and stored directly in the PLC for further
processing. Using this type of system architecture, logical functions are performed by the
generic printer controller with the PLC providing localized system customization to
implement the instructions supplied by the controller.
3.5 Compose IQ Dongle
The Dongle is a serialized device that is installed in one of the USB ports of the controller.
It acts as the license enabling mechanism for users with a Compose Version of 6 or later.
It must have a valid dongle information file encrypted within it to become active. The
correct dongle information file specific to the serial number of the physical dongle and to
the print technology and Compose functionality purchased is required. The Dongle is
field-programmable so that options may be added without swapping Dongles. The Dongle
requires drivers that are loaded with Compose V6.03 or later. In the Compose Help system
the driver installation procedure is listed.
3.6 Compose Software
For more detailed information about Compose IQ, reference the help file included with the
software. Only some of the basic functions are described in this manual.

3.6.1 Printhead Drivers
In order to integrate the print technology with Compose, the proper printhead driver must
be specified in the Setup menu as well as its relative distance from the photo sensor
(Figure 3-2).
Figure 3-2: Compose Setup Window
3.6.2 Diagnostics Screen
The Compose diagnostic screen displays the voltage and temperature readings for each
printbar (Figure 3-3). The voltage value can be different for each jetting assembly. As a
result, it is preset before shipment with the factory settings. The normal voltage range for
an Atlas or Aurora printhead is 80-100 volts. The temperature reading depends on the ink
technology used.
