PREFACE
This Service Manual describes fundamental field service for the BJ-W3000/BJ-W3050 large
format printer.
This Manual is composed of the following chapters:
Chapter 1 General Description: Features, specifications and operating procedures
Chapter 2 Basic Operation: Operation of mechanical and electric functions
Chapter 3 Mechanical System: Mechanical setup and assembling/disassembling procedure
Chapter 4 Maintenance and Servicing: Periodic parts replacement, Standard service life of
consumables, Periodical services, points of maintenance and inspections
Chapter 5 Troubleshooting: Service mode, adjusting and settings, operation trouble
Descriptions in this manual are based on the following conventions.
1. In the Basic Operation section, the roles of each function, relationships between electrical
and mechanical systems, and the timing for each part are summarized.
The mark indicates mechanical drive transmission. The mark
accompanying a signal name indicates the flow of electrical signals.
Flow charts are also used in the summary of operation.
The symbols used in the flow charts are as follows:
Start/completionOperationDecisionRemedyJumpStop
2. In the descriptions of digital circuits, "1" or "H" indicates a high voltage level, and "0" or
"L", a low voltage level. However, the actual voltage values vary depending on the circuit.
3. It is assumed that the Printed circuit board (PCB) will not be repaired by the user. There-
fore, the descriptions of the circuits on the PCB are limited to block diagrams.
4. Troubleshooting is described using procedural tables.
The procedural table is a variation of a general flow chart.
An example is shown below.
e.g. No power is supplied.

•If you want to know the possible causes of any specific problem (suspected parts), refer to
the "Cause" column in the table.
In the event "No power is supplied" as shown in the above table, an unplugged power
source, power source failure, blown fuse, and other causes can be considered.

•In order to remedy a problem, check the Steps in order. Answer the first "Check item"
question. If your answer matches that given in the "Result", follow the corresponding procedure in the "Remedy" column. If your answer is not the same, go on to the next step and
repeat the same procedure.

•When checking voltages using a tester is required, it will be specified in the check item.
For instance; "measure the voltage between J102-1 (+) and JI02-2 (-) on the engine controller PCB". In this case, apply the plus and minus leads of the tester to the (+) and (-) terminals indicated after the connector numbers:
e.g.JI02-1 (+): Plus lead
JI02-2 (-): Minus lead
5. The signal address of the circuit diagram is shown by applicable pages of each controller
(indicated at the upper right of the circuit diagram) and its location.
CAUTION
When checking voltages with a tester, touching the components or connector terminals on
the PCB with the hands may cause an electric shock. It is advisable to wear rubber gloves
or the like when power is supplied to the machine to protect yourself from electric shock.

Menu
¥ This machine can receive, analyze and print data. When printing is
started, "Printing" appears on the message display.
¥ While online, only the online key is functional. To use the other keys,
this machine should be offline or in the menu state.
¥ If no data is received for 5 minutes in this state, the printer enters the
sleep state.
¥ If data is transmitted from the host in the offline state, the printer will
ignore it.
¥ The roll media can be fed and the carriage can be moved.
¥ If no data is received for 20 minutes, the printer enters the sleep state.
¥ Printing is paused. As long as, there is sufficient space in the buffer
memory, data is received and analyzed continuously. When the reception
buffer becomes almost full in the pause state, the mode is shifted to
receive data at 1 byte/sec.
¥ By pressing the online key in the pause state, the printer will enter the
menu state.
¥ Menus and parameters can be set up. The menu items available when
paused are more limited than those available when in offline state.
Printing
Sleep
¥ The printer is printing.
¥ The operation panel keys cannot be used in the printing state. To use
the keys, the printer should be in the pause or menu state.
¥ All lamps and the display (other than the power lamp) are off.
¥ When paper is loaded and data is transmitted from the host, the printer
automatically enters the online state and starts printing.
