Two ribbon cables provide the electrical interface between the ink core
module and the electronic system. The cables connect directly from the ink
core module to the PIB and allow for the transfer of the following signals:
• Ink pump motor control signal
• Pressure sensing signals (2 sensors)
• Ink temperature signal
• Valve control signals
• Mixer tank level detecting signals
• Ink system smart chip information (refer to “Smart Cartridges” on
page 3-23 for additional information).
Ink Core Pump
The ink core pump is a positive displacement gear pump driven by a 24
VDC brushless motor.
The pump provides stable ink pressure to the nozzle during printing and
also provides a flow of ink to other components inside the ink core
module.
Ink Core Module Functions
The phasing and velocity fly-by sensors and supporting circuitry
contribute directly or indirectly to the performance of six critical control
functions during steady-state operation:
• Phasing
• Modulation control
• TOF measurement
Rev AA
Ink Compartment
3-21
Videojet 1510 Service Manual
• Pump speed control
• Target pressure control
• Viscosity control
The functions of the ink core module are shown in Table 3-12.
Name
Function
Frequency
Phasing
Between prints, charge transfer to test drops is measured by
the LEAD fly-by sensor (phase detector) in order to
synchronize drop charging to drop break-off, thereby
optimizing print quality.
Performed
approximately
25 times per
second
Modulation
Control
Between prints, modulation amplitude is validated by
performing an abbreviated auto-modulation test using the
LEAD fly-by sensor (phase detector). The amplitude is
changed in small increments whilst measuring the rate of
change of the phase angle in order to verify that the
amplitude setting remains at or near the “appropriate setting”.
Performed
continuously
TOF
Measurement
Between prints, drop velocity is monitored by measuring the
TIME OF FLIGHT of the test drops from the LEAD (phase)
sensor to the TRAILING (velocity) sensor. The measured
result is referred to as the “actual velocity”.
Performed
every TENTH
phasing test
Pump Speed
Control
A pressure transducer inside of the Core measures “actual
pressure”. This pressure is compared to the “target
pressure”. The resultant error is used to increase or
decrease the pump speed.
Performed
once per
second
Target Pressure
Control
The “target pressure” represents the nominal pressure the
printer determines that it must operate at in order for the
actual velocity to be equal to the “velocity set point”. The
printer makes modifications to the target pressure by
reviewing the “history” of the velocity error parameter (“PID”
control). “Velocity error” refers to the difference between the
actual velocity and the set point.
Occur every
10 seconds
Viscosity
Control
Once the printer has determined its “target pressure”, it has
the means to perform viscosity adjustments. Determination
concerning viscosity is made by comparing the empiricallydetermined “target pressure” to a reference pressure known
as the “temperature-compensated target pressure”. This
value is acquired indirectly from data encoded on the ink cartridge Smart Chip. This reference pressure is mathematically
determined and represents the pressure required to acquire
the correct “actual velocity” under ideal viscosity conditions. If
the target pressure deviates from the reference pressure, the
printer attributes this to viscosity variation and responds
accordingly.
Occurs every 5
minutes (if
necessary)

Nozzle
The nozzle (item 8, Figure 3-26 on page 3-27) creates the ink droplets.
Charge Electrode
The charge electrode (item 9) applies an electrical charge to each ink
droplet. The charge applied to the droplet is variable and affects the
position of the droplet on the substrate.
Phase Detectors
The phase detectors (item 12) measure the ink drop velocity and perform
phasing.
Gutter Tube
The gutter tube (item 11) is the return path for the uncharged ink droplets
that are not used for printing. The gutter delivers the ink back into the ink
core.
The gutter detect senses when ink is present in the gutter. The ink feed
tubes are metallic and a signal is fed to one of them. A signal return lead is
connected to the other. When ink (which is conductive) is present, the
signal passes through it to the return lead. The gutter detect signal is then
fed, via the umbilical, to the CSB in the electronics system.
Deflection Plate
The deflection plate (item 10) is supplied with a fixed positive DC voltage
(0 - 8000 VDC) from the EHT Module. This voltage deflects the charged
drops over the top of the gutter, through the printhead slot, and onto the
substrate.

2 The ink and solvent mixture enter the feed valve (item 4).
3 The valves open or close as per the print requirements.
Note: The bleed valve opens and closes as needed during flushing the nozzle
and suppling ink to the nozzle.
4 The ink and the solvent mixture flow into the nozzle.
To adjust the nozzle refer to“Align the Ink Stream” on page 4-26.
5 The piezoelectric crystal vibrate the nozzle at a frequency of around 75
KHz nominal value in the longitudinal direction.
This vibration enables the nozzle to breakup the stream of ink into
droplets.
6 The ink drops enter the charge electrode (item 9) where they are
charged at different voltage levels based on the character to be
generated.
7 The charged ink drops then pass through the EHT/ High Voltage
Field (item 2, Figure 3-27) and over the phase detectors.
3-28

Rev AA
Videojet 1510 Service Manual
8 The High Voltage/EHT plate deflects the charged drops of ink at
various angles depending on the charge placed on the drop at the
moment of breakoff.
9 An electrically conductive ink is supplied under pressure by the ink
core to the nozzle assembly (item 6, Figure 3-28) through the ink feed
pipe (item 1).
10 An ink stream is formed as the ink is forced out of the nozzle jet orifice
(item 5).
A modulation signal is applied to a ceramic transducer which is
clamped to the nozzle assembly. The transducer crystals (item 3 and
item 4) causes the nozzle assembly to vibrate longitudinally, breaking
up the ink stream into droplets, a small distance away (the break up
point) from the nozzle jet orifice. The frequency of modulation is 76.8
kHz (nominal value).
The ink droplets are produced at the same rate as the modulation
frequency and are uniform in size and separated by equal distances.
The nozzle orifice diameter is 70 microns.

Figure 3-29: Charge Electrode
The ink stream and the charge electrode can be considered as the two
electrodes of a capacitor. By raising the charge electrode to a specific
positive voltage (with a charge pulse) the section of the ink system within
the charge electrode will have a negative charge induced on it. When a
drop of ink then breaks from the jet it will have trapped on it a charge
directly proportional to that on the charge electrode. If the positive voltage
is then removed from the charge electrode, the negative charge on the jet
will discharge through the ink jet and nozzle assembly to ground.
However, the drop of ink which has become detached from the jet cannot
discharge as it no longer has a conductive path to ground.
Droplet Deflection
12 The droplet stream passes through an electrostatic field maintained by
the deflector electrodes that are connected to a high tension supply
(typically 6 kV).
13 The negatively charged droplets are deflected by the field towards the
high voltage deflector electrode.
The distance a drop is deflected is proportional to the charge carried,
which is in turn proportional to the voltage applied to the charge
electrode when the drop became detached from the ink jet.
The charged droplets once deflected leave the printhead to form
characters in a dot matrix format on the substrate. Droplets which are
not required for printing are not charged and are therefore not
deflected.

Install the Encoder
When product speed is constant, the printer uses internal encoding.
External encoding (that is shaft encoder) is used when the speed of the
conveyor varies.
Internal Encoding
An internal clock sets the stroke-rate to a constant pace. Refer to “When to
Use Internal Encoding” on page B-1, for more information on internal
encoding.
Do the following tasks to set encoding source to internal source:
1 Navigate to Configure> Shaft Encoder Source. The Print Control menu

Note: If the line speed varies, then an external shaft encoder must be fitted in
order to maintain constant message width (refer to “External Encoding” on
page 4-22).
Note: A width of 1 will provide the fastest print that the printer can achieve
in each font using the Internal Shaft Encoder option (refer to Figure 4-25).
The message width is increased by approximately 3% for each increment.

External Encoding
To install an external shaft encoder, do the following tasks:
1 Turn off the printer.
2 Connect the shaft encoder cable to the shaft encoder connector. See the
following pictures for connections:
• Figure 4-26 on page 4-22 - Shows the shaft encoder connector on the
connector panel.
• Figure 4-1 on page 4-3 - Shows the installed shaft encoder and the
related connections.
• Figure 4-27 on page 4-23 - Describes the shaft encoder connector
socket pin layout.
Note: The printer can be configured to accept two shaft encoder (quadrature)
outputs. This allows the printer to compensate for changes in direction of the
production line.
Note: Using quadrature shaft encoders to determine changes of direction
disables the width function (that is, the width must be set to 1). If width
control is required, an external divider box must be provided.

• Checks that increasing the phase offset moves the output negative by
0.4 V.
• Checks that increasing the charge offset moves the output positive by
0.4 V.
• Halves the charge scale.
• Re-establishes the charge output within the range ±1 V.
• Checks that the output moves by 0.2 V when the charge offset is
increased by one bit.
SRAM
This test checks writes sixteen random values to the SRAM at each single
address bit transition (0, 16, 32, 64, 128...) then reads and checks all values
are correct.
EHT
This test does the following checks:
• Checks for a fixed voltage on EHTVMON [2.41, 3.04].
• Checks for a fixed voltage on EHTIMON [1.83, 2,61].
• Ramps the EHT setpoint into a fixed load and checks the measured
current is correct.
Levels/Pressure/Vacuum
This test does the following checks:
• Checks for a fixed voltage on the pressure signal [2.15, 2.63].
• Checks for a fixed voltage on the vacuum signal [2.68, 4.10].
• Switches on only VALVEDRIVE_6, 7 and 8 in turn and checks that
only level sensor INK1, 2 then 3 is shorted respectively.

Modulation
This test ramps the modulation into a fixed load and checks the measured
voltage and current are correct.
Phase Detector
This test does the following checks:
• Checks for a fixed voltage on the phase detector input [2.75, 3.85].
• Checks for a fixed voltage on the velocity detector input [0.91, 2.15].
• Sweeps the phase and velocity thresholds from below to above these
fixed voltages to check the comparators work.
Pump
This test runs the pump driver (using the RELAY4-6 outputs to emulate
rotation on the Hall sensor inputs) into a dummy load and checks the
current drawn is correct and the TACHO output matches the Hall sensor
inputs.
Valves
Turns on VALVEDRIVE_9 to VALVEDRIVE_13 only in turn and checks
the valve driver current is within range.
DIN Interface
This test does the following checks:
• Checks for connections between the following beacon drive and PEC/
SENC signals.

Manual Tests
This test sets the modulation up as a 250Vpp 76.8kHz sine wave and a
300V high staircase waveform on the charge and asks the user to check
them on the scope.
The user is then asked to turn the board off and check the bleed valve
holdup circuit works by checking the brightness of the BLEED LED on the
test box.

Illustrated Parts List
10
The Illustrated Part List (IPL) contains the illustrations and the parts lists
for the different assemblies in the printer. The parts lists give the part
numbers, description and quantity of all the items and the modules in the
printer. You can order the items and the modules for which the part
numbers are given.
How to Read the IPL
This section describes how the higher assemblies are broken down to their
related sub assemblies and other separate parts.
Illustrations
Table 10-1 on page 10-2 shows the symbols used to indicate the different
levels of main assemblies in a printer, and the sub assemblies under the
main assembly.

Indicates further explosion.
Alphabets
• An alphabet is assigned to the main assemblies of a printer and each
sub assembly under the main assembly. See Figure 10-1 on page 10-3.
For example: If A, B, C and D identify the main assemblies of a
printer, then the alphabets E,F, and so on identify sub assemblies
below each main assembly in a sequence.
• The alphabets assigned to main assemblies are used only for one time.
• The alphabets “I” and “O” are not used because they look like the
numbers 1 and 0.

Numbers
A natural number (1,2,3.....) is assigned to the stand alone parts (in
ascending order) through out the breakdown of main assemblies. See
Figure 10-1.
Note: The numbers assigned to main assemblies can be used only for one time.

Clean Start
This method starts on flush (pure solvent) in order to dissolve any ink
residues in the jet orifice. It then bleeds on flush to remove air from the
nozzle before switching to ink, eliminating ink splash and spray during
start-up.
The Clean Start Jet Sequence is as follows:
1 The solvent from the filter is forced through the umbilical connection
into the printhead.
2 At the printhead, the solvent enters the heater manifold and passes
into the main fluid path between the jet valve and the nozzle.
3 The jet starts when the nozzle becomes pressurized by the solvent
flow.
4 If the previous stop was a clean stop, the jet will consist of almost pure
solvent. The flow of solvent quickly removes any ink residues in the
jet orifice.
5
Fluid in the jet is caught by the gutter and directed to the ink core.
6 Approximately ten seconds after the flush pump switches off, the
bleed valve closes and ink continues to flow through the jet at 4 bar.
7
Modulation is switched on and the ink pressure changes to give the
correct jet velocity.
8 Heater manifold temperature is allowed to reach the correct value
before enabling the phasing checks on the jet.
Quick Start
This method starts without a flushing sequence, and uses the ink supply
to bleed air from the nozzle.
Clean Stop
This method switches from ink to flush in order to purge the nozzle. This
method allows time for the manifold, nozzle and jet orifice to be purged of
ink before stopping the jet.
The Clean Stop Jet Sequence is as follows:
1 Deflector plate voltages are switched off before beginning this
sequence.
A-2
Clean Start
Rev AA
Videojet 1510 Service Manual
2
The ink pressure is set to 4 bar and the modulation voltage switches
off.
3 To increase the ink flow through the nozzle body, the bleed valve
switches on.
4 The flush pump valve switches on applying solvent pressure to the
printhead.
5
Pure solvent is forced through the filter to the printhead mixing
solvent into the ink stream in the heater manifold.
6 Approximately one second after the solvent starts to mix with the ink,
the feed valve (V6) in the cabinet switches off, removing ink pressure
from the printhead.
7 Ink ceases to flow into the heater manifold and the solvent flushes ink
from the nozzle body.
8 Five seconds later the bleed valve switches off and then switches on
again, introducing solvent into the jet valve, which inhibits ink
residues forming whilst the machine is switched off.
9 The jet valve (on the heater manifold) switches off, ensuring that no
ink diffuses into the solvent. At this point, no ink should be present in
the nozzle body.
10 The gutter valve switches off, increasing the suction on the bleed
system. After a short pause, the bleed valve switches off.
11 After another short pause, the gutter valve switches on to clear any
fluid from the gutter.
12 Once the gutter valve switches off, the main ink pump also switches
off.
Quick Stop
Note: This sequence is used to manually stop the jet for a short period, or to
automatically stop the jet during an EHT trip, charge error, etc.
This method switches off the ink without flushing the nozzle or manifold.
Hence the manifold and the nozzle are full of ink when the jet stops. The
machine must not be left in this state for long periods, as drying ink in the
jet orifice may make restarting difficult. This procedure is primarily
intended for situations where the machine may be stopped and restarted
several times in quick succession. Under these conditions, the use of
solvent may become excessive and cause dilution of the ink.

Nozzle Flush
When Nozzle flush is selected, the vacuum from the venturi is applied to
the return side of the nozzle, creating suction at the nozzle orifice. Solvent
is applied to the nozzle orifice to clear any blockage.
Nozzle flush will automatically time out after 2 minutes but can be
stopped at any time before that by pressing F1 key Abort Flush.
A nozzle flush can be started with the jet running or stopped. If the jet is
running, selecting Nozzle flush will first of all de-energize feed valve V6
to stop the flow of ink to the nozzle.

Encoder Information
B
Internal Encoding
This is used when product speed is constant. An internal clock sets the
stroke-rate to a constant pace. Refer “When to Use Internal Encoding” on
page B-1, for more information about internal encoding.
When to Use Internal Encoding
Internal coding is used when the product speed is constant. The internal
clock of the printer is set to the speed of the product in feet per minute
(FPM) or meters per minute (MPM)
Note: Internal encoding is also used when test printing a sample message. For
information on test printing a sample message, refer to...
It is necessary to determine the product speed. Below are four methods
that can be used to determine the product speed.
Rev AA
Internal Encoding
B-1
Videojet 1510 Service Manual
Method 1
Use a handheld tachometer that is calibrated to measure linear surface
speed in FPM or measure the revolutions per minute of the pulley.
Convert RPM to surface speed by using the following formula
Surface speed (FPM) = [Πd x (RPM)]/12
where Π = 3.14
where d = pulley diameter in inches
Method 2
Establish a reference mark on the conveyor belt and measure how many
inches (one inch equals 25.4 mm) this mark moves in 5 seconds. This
number is equal to the conveyor speed in FPM
Method 3
If you know the number of products produced per minute on the line, the
size of the product, and the gap between each product, you can calculate
the product speed.
For example:
1200 products per minute are produced on the line, each product is 2.5
inches wide, and there is a one inch gap between each product.
Conveyor speed = [(products per minute) x (size + gap)]/12
where size and gap are in inches
Method 4
It is also possible to use the printer’s product counter to determine the
number of products per minute, and then calculate the line speed as
shown in “Method 3”.
External (Reduce Or Direct) Encoding
A shaft encoder is used when the speed of the conveyor varies. Shaft
encoders may either be direct coupled or divided-down:
• A direct encoder maintains a 1:1 ratio between the encoder
pulses and print strokes.
• A divided-down encoder is used when the conveyor speed
requires fewer pulses than the actual output of the shaft encoder.
The following are the three methods to do encoding:
This is used when product conveyor speed is not constant. A shaft
encoder must be used with this selection. The shaft encoder monitors

changes in conveyor speed and varies the stroke rate accordingly. Select
REDUCE if the encoder rate input must be electrically divided down for
use. Select DIRECT if the encoder input can be used without dividing.
Refer “When to Use External Encoding” on page B-3, for more
information about external encoding.
When to Use External Encoding
External coding is used when printing is required when the speed of the
product and conveyor changes. In this case, a shaft encoder is required.
The shaft encoder is coupled to the conveyor at a point where the selected
conveyor shaft and the conveyor are turning together. The shaft encoder
will provide either one pulse or many pulses (which are mathematically
divided) for each vertical stroke of the message.
d
d = distance of conveyor (product) travel per revolution of shaft
Figure B-1: Product Distance
Required shaft encoder:
Pulses per Revolution (PPR) = d x (strokes per inch)
Where strokes per inch = (strokes per character) x (characters per inch)
Example 1
Given information:
d = 23 inches
5 x 7 matrix
10 characters per inch
6 strokes per character
(five printed strokes from the 5 x 7 character, plus one “guard” stroke that
leaves a space between the characters.)
23 inches per revolution x 60 strokes per inch = 1380 PPR

Videojet 1510 Service Manual
Example 2
If the standard 1800 PPR shaft encoder is to be used as shown in Example
1, it will be necessary to provide some type of gearing to supply the
required 60 pulses per inch as shown in Figure B-2.

Figure B-2: External Shaft Encoder
To determine the required gearing, the following method is used.
1800 PPR/1380 PPR = 1.3 or 1:3:1 gear ratio

1. Pulley b
2. Pulley a
Figure B-3: External Shaft Encoder - With Pulley
If the diameter of “a” = 2.0 inches, then the diameter of “b” is 2.6 inches
(2.0 inches x 1.3 = 2.6 inches). For one rotation of “a”, 1380 pulses are
produced from the 1800 PPR shaft encoder.
If that same 1800 PPR shaft encoder is connected directly to the shaft on
the conveyor, the calculation would be as follows:
(1800 pulses per revolution)/(23 inches per revolution) = 78 pulses per
inch
(78 pulses per inch) / (6 strokes per character) = 13 characters per inch
Since the standard calls for 10 characters per inch (refer to Example 1), the
message would be compressed on the product.

Auto Encoding
This is used when the product speed varies from that of the conveyor
(product slippage). With this selection, the signal from the product
detector is used to determine product speed. Refer “When to Use Auto
Encoding” on page B-5, for more information about auto encoding.
When to Use Auto Encoding
Auto Encoding is used when the speed of the product is changing due to
slippage on the conveyor or when the product is allowed to fall through
guides from one level to another.
When set for Auto Encoder, the printer will determine the speed of each
individual product, and then code that product at a set stroke rate. The
printer needs a product detector installed in order to work with auto
encoding. In addition, the length of the detect area (the amount which the
detector senses) must be known and entered into the printer.
