Using this manual

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.

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.

Functionality

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:

6 Chapter 1 Printer systems

ENWW

●Take-Up Reel

●Vacuum Fans (passes through; the actual control is inside Eola)

●Valves and Motors for Primer, Rack Engage, SVS, and Aerosol Fan

●Top Cover Fans

●Rewinder Motor

●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: Heating-System Electronics 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.

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:

●Ink-Supply presence detection

●Ink-Cartridge broken-bag detection

●Ink-Supply smart-chip interface

●Air-Pressure measurement and air-pump shutdown

●Humidity and temperature measurements

●System back-up EEPROM

Below is a picture showing the connections and components located at the rear of the ISS.

10 Chapter 1 Printer systems

ENWW

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:

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.

NOTE: The Power Distribution Unit (PDU) must be rated to meet the power requirements of the printer, and be in accordance with the Electrical Code requirements of the local jurisdiction of the country where the equipment is installed.

WARNING! Do not use a power strip (relocatable power tap) to connect both power cords.

Wall receptacles and power cords

Two power cords are provided with your printer, according to the printer's electrical specifications. If those cords do not reach your PDU and/or UPS, a certified electrician must install suitable extension cables on the day of installation.

To make sure you have the right wall socket outlets (wall receptacles) ready for installation, check the following:

1.The wall socket outlets must be suitable for printer input ratings. See Single-phase power on page 14.

2.The wall socket outlets must be suitable for the power cord plug type used in the country of installation. The list shows examples of the power cords and the plugs provided with the printer according to the country. To make sure you have the right wall receptacle, find your country in the appropriate table and check the plug type.

WARNING! Only use the power cord supplied by HP with the printer. Do not use a power strip (relocatable power tap) to connect both power cords. Do not damage, cut, or repair the power cord. With a damaged power cord, there is risk of fire and electric shock. Always replace a damaged power cord with an HP-approved power cord.
