Purpose
This service manual contains information necessary to test, calibrate, and service the HP Latex 300 printer
series.
For information about using the printer, see the user’s guide.
Chapters
1 Printer systems
Use this chapter as a reference for technical information about the subsystems, components, and how they
work together.
Of particular importance are the diagrams included for each subsystem of the printer. They can be useful for
both troubleshooting and disassembly.
2 Troubleshooting
Whenever a printer is not functioning correctly due to a fault, use this chapter for step-by-step diagnosis
until you arrive at the solution, which may include replacing a part.
Troubleshooting always begins with a problem; so, when you enter the chapter, navigate to the proper
section and find the troubleshooting steps for your problem.
This chapter does not cover the procedures for the diagnostic tests you must perform while troubleshooting,
nor the replacement procedures you must complete to fix the problem.
3 System error codes
This chapter contains the system error codes which are displayed on the front panel and by the Embedded
Web Server. Each system error code shown in the chapter has a brief description and the steps required to
solve the error.
Most of the troubleshooting steps involve performing a test or a calibration, which can be found in the
following chapter. Before replacing any part that you suspect of causing the system error code, always
perform the test or calibration.
4 Tests, utilities, and calibrations
Use this chapter whenever you need to perform a diagnostic test, service utility, or service calibration. This
chapter is meant to provide procedures and relevant information, not troubleshooting information. For
troubleshooting information, see the Troubleshooting chapter.
These procedures are described in full, so that you know any relevant values for the test, as well as
information about what the printer is actually doing during the test.
The goal of diagnostic tests is to locate the root cause of the problem and the corresponding system error
code or message that will provide you with logical steps to resolution.
Some diagnostic tests or calibrations must be performed after removing a component.
5 Print quality
This chapter describes the print-quality diagnostic procedures. Further troubleshooting advice can be found
in the user’s guide.
6 Ink supplies
This chapter describes and discusses the components of the ink supply system.
ENWW v
7 Parts and diagrams
The purpose of this chapter is to detail all of the available service parts of the printer. This information is
presented in tables, organized by subsystem, and includes the following:
●
Official service part names
●
Part numbers
●
Illustrations of the service parts
Use this chapter whenever you need to order a service part.
8 Removal and installation
The purpose of this chapter is to provide procedures for removing and installing service parts. Each service
part has a removal procedure detailed in this chapter, and installation procedures and notes are included as
needed.
Useful information such as access notes and screw types (head sizes) are provided to help you work
efficiently.
9 Preventive maintenance
Maintenance alerts are displayed by the front panel and Embedded Web Server whenever maintenance is
required. While most of these alerts can be resolved by the customer, some require a service engineer.
Use the preventive maintenance chapter whenever you need to perform a preventive maintenance procedure
due to an alert the customer receives from the front panel or Embedded Web Server, or to get reference
information on life counters and maintenance that must be performed by the customer.
10 Move, store, or repack the printer
This chapter gives advice on moving, storing, and repacking the printer.
11 Safety precautions
This is an industrial printer that uses high voltages: service operations can be hazardous. The safety chapter
covers all the guidelines and checks you need to perform in order to service the printer.
You are expected to have appropriate technical training and experience necessary to be aware of hazards to
which you may be exposed in performing a task, and take appropriate measures to minimize the risks to
yourself and to other people.
Readership
The primary readers of this service manual are HP service engineers, although secondary readership may
include resellers. All procedures must be performed by HP service engineers or authorized service-delivery
partners, except for those procedures clearly marked otherwise.

Interconnect PCA
The Interconnect PCA is an interconnect board with connectors that helps distribute power, and control
signals from the Printmech board, to all the elements connected to the right side of the machine, including
the following:

●
Pinch Lever, Media and Window Sensors
Formatter PCA
The motherboard of the printer. It is the same type of board as found in a standard computer.
Engine PCA
The main controller of the printer. It is responsible for all the processes performed in real-time, and is the
ultimate controller of all electromechanical systems. The Engine PCA controls all substrate path components
(Drive Roller, Spindle Motors, OMAS, etc.), and all non-substrate path components (Carriage, Scan Axis Motor,
Print Head Cleaning Assembly, Service Station, etc). Attached to this board, is the Printer ID PCA.
Printer ID PCA
Contains printer identification. When replacing the Engine PCA, take care not to lose it.
OMAS PCA (360 only)
Controls the Optical Media Advance Sensor, used to measure substrate advance.
LAN Communication Card
Provides LAN communication.
Solid State Disk Drive (SSD)
Contains:
●
The printer firmware
●
The operating system
●
All calibration values, product number, serial number, and so on. In order to avoid loss in the case of
SSD failure, a backup is made in the ISS top board.
IMPORTANT: In order to prevent any loss of calibration values, do not replace the following at the same
time:
●
The Hard Disk Drive and the ISS Top Board.
Power Supply Unit (Main PSU)
This PSU delivers power to all the parts of the printer except heater elements. The internal rails are: 5V_sb;
3V3, 5V, 12V, 24V, and 42V.
PrintMech PCA
The PrintMech PCA is mainly used to control the mechatronics of the printer. For routing reasons, only the
parts connected to the left side of the printer are connected to this board:
●
Scan-Axis Motor
●
Substrate-Axis Motor
●
Ink Pressurizing Pumps and Valve
ENWW Electrical system 7
●
Ink Collector Sensors
●
Ink Supply PCAs Connection
●
Inner Light PCAs Connection
●
Spit-on-Roll Motor (routed to the right side of the printer)
The remaining functionality implemented in the PrintMech PCA is sent to the right side of the printer through
the Mini Interconnect PCA and its three cables (power + data).
Heater Control
Converts the input voltage from the mains to a voltage in the output that is controlled by the Curing Control
PCA, and depends on the quantity of power required for impinging.
The converter has three cables: one power cable for the input, one for output, and finally the control cable.
The control part of the converter that interfaces with the Curing Control PCA is powered at 24 V.
There are three LEDs: Status (off or fault), PWM (if power is being delivered to the output), and ACOK (if Vin is
in range).
Air Curtain and Printzone Heaters control PCA
Controls the Air curtain and Printzone Heaters. For further details refer to:
on page 11.
Carriage Electronics
Description
The carriage contains electronics for controlling and firing printheads. It also contains electronics for
controlling the external sensors (SOL and Tetris) and the scan-axis encoder.
Heating-System Electronics
The electronics of the carriage receive power and data from the trailing cables, which include both power
(+42V) and data (LVDS) cables. The power cable connects the carriage with the Mini interconnect board, and
the data cable connects the carriage with the engine PCA.
Components
Carriage PCA
The carriage PCA contains electronics that control how and when the ink is dropped from each printhead. It
receives information from the sensors.
8 Chapter 1 Printer systems ENWW
SOL Spectrophotometer (HP Latex 360)
The SOL is a color sensor located on the left side of the carriage. The main function of the SOL is to measure
color samples printed on the loaded substrate, and then placed in the print platen zone.
Before taking any color measurement, the SOL must be initialized. The SOL initialization process takes
approximately 7 minutes. This process consists of three steps:
●
Sensor switch on
●
Sensor warm up
●
Sensor calibration
When the initialization process has finished, the shutter opens automatically and the carriage is moved along
the scan axis to place the SOL on top of each sample and take a color measurement. After the
measurements, the shutter is closed, and the sensor is switched off.
Tetris
The Tetris is used to align the printheads, and to locate the edges of the substrate and measure its size. The
alignment procedure consists of a series of patterns first printed, then scanned using the Tetris, and finally
an internal process is used to correct the timing of when and where the nozzles of the printheads fire, and
detect any possible nozzle-out issues.
Scan-axis encoder
The line encoder is located on the carriage; it measures and counts the movements of the scan axis. An
optical, infrared wavelength encoder is used: the same type of encoder used in most of the HP large-format
printers. The encoder signal is converted to LVDS logic levels, and directly routed through the data TC.
Printhead flex
To connect the carriage to the printheads, a delicate flexible circuit with small golden dimples is used.
Printheads are inserted into unique slots and a spring-loaded mechanism pushes the electrical contacts of
the printheads into the printhead flex, which subsequently connects the printhead to the carriage electronics.
Printhead flexes are the most delicate and sensitive part of the carriage. If the printheads are inserted with
too much force, or they are misaligned, they can easily be damaged.
Ink Supply Station (ISS) Electronics
Description
There are two ISS PCAs (as in the DJ L25500/L26500 printers).
ENWW Electrical system 9
Components
Top and bottom ISS PCAs
The ISS electronics are powered from a +12 V line coming from the PrintMech, and a linear regulator on the
ISS PCAs generates the +5 V used to power all the devices on the board.
The ISS PCAs are two electronic PCAs located at the rear of the Ink Supply Station. The ISS PCAs provide the
following:

Both top and bottom ISS PCAs share the same PCB; the only difference between them is that the bottom PCA
is a simplification of the top PCA. The top PCA contains these additional parts:
●
EEPROM
●
Connection from the PrintMech PCA
●
Air pressure sensor
●
Temperature and humidity sensors
Both PCAs are connected through an 8-pin connector. The second ISS connector is connected to the
PrintMech PCA in a daisy-chained connection, the first ISS board by means of this 8-pin connector.
Vacuum-Fan Electronics
Description
There is one EOLA PCA to control two different brushless blowers generating the required vacuum to hold the
substrate. This PCA is connected to the Mini interconnect PCA (right side).
Heating-System Electronics
Description
In the Latex 360 Power, power is delivered to 3 subsystems:
●
Impinging (Drying and curing): Controlled through Curing Control PCA
●
Air curtain: Controlled through Air Curtain and Printzone Heaters Control PCA
●
Print zone heating: Controlled through Air Curtain and Printzone Heaters Control PCA
WARNING! The PRI (POWER) area is not isolated, and there is an electrical shock hazard. The PCA is
connected directly to the AC mains input. The power cords should be disconnected before manipulating the
power elements.
The following diagrams show configuration, the Primary area, and its connection:

Components
Air Curtain and Printzone Heaters Control PCA:
12 Chapter 1 Printer systems ENWW
The Air Curtain and Printzone Heaters Control PCA is only present in Latex 360 printers, and is placed inside
the EEbox. The Air Curtain and Printzone Heaters Control is the PCA that controls the power delivered to the
air curtain resistors and the printzone heaters. The AC power input comes from the Main PSU, but there is a
pass through from the input power plug to the PCA AC input. The PCA has a primary non-isolated area, and a
SELV isolated area. The power available is balanced between both subsystems based on burst control, the
control is provided from the same PCA. The Air Curtain and Printzone Heaters Control also controls both
subsystems' fans; the ambient temperature sensor, and the box fan installed for cooling the PCA.
Curing Control PCA:
The Curing Control PCA is placed at the impinging bracket on its left side and executes the servo that applies
the power to the impinging module. The Curing Control PCA is present in all three SKUs; In the Latex 360
printer it controls the impinging sensors (Temperature and pressure) and the Heater Control, and in the Latex
330 & Latex 310 printers, it controls the air curtain fans, and reads the ambient temperature sensor. The
Curing Control PCA has no power (PRI) lines.
Curing Power Interconnect:
The Curing Power Interconnect PCA is placed just above the Curing Control PCA. Both PCAs are housed in the
same fire proof box. The Curing Power Interconnect PCA is connected to power lines and provides the
interconnection interface for the curing module, and for the air curtain resistors (Latex 360 only). The Curing
Power Interconnect PCA is present in all three SKUs.
