2.1.2 Fuse Connection Diagram 1.0
 Procedure when the fuse is blown

1) Refer the following fuse connection diagram. Check if there is any adhesion of ink or cleaning solution to the PCB
or cable that is connected to the blown fuse, and check whether there is incorrect cable connection. → If there is
abnormal, replace the parts.
2) Replace the PCB of the blown fuse.
1
3) By the tester measure the resistance between the fuse and GND after the replacement.
 1. If the resistance is 0 to several Ω, it will be determined to be short forward the fuse.
1.Remove a sensor, motor, head, and cable, etc that are connected to PCB.
2.Check it for a short again, if it is not short circuited, connect the removed parts one by one.
2
3.Repeat above 2. and replace the parts where the short was confirmed.
4.if a short circuit persists even after removing the sensor and motor related, replace the PCB.
5.Make sure that the short is gone, and turn on the power.
 2. It has not been short, or if you can not confirm the short, leave removing the parts associated with the error that
had occurred just before. (Example; Occurred HD THERMIS [12] → remove the head?
1.If fuse is blown after the power is turned on, exchange the removed parts. 3
2.If the fuse is blown again, it is judged that there is a short circuit in another part. Repeat from 1).

resistors. Therefore, fix the Fusing resistors at a place you want, using acetate cloth tape or seal clamp, and
so on.
*2 : When installing the new power supply (PLA600F-36-R) to the model that uses the old power supply

 Head replacement procedure

Use the following procedure to replace the head when inspecting for failure, etc.
 Pay careful attention to the following when replacing the head.

1. Be sure to attach a test pattern. The head and test pattern should match exactly.
1
If the same No. head is replaced continuously due to recurring failure, write the serial number of
the head on the test pattern to clearly identify the relationship between the failed head and the test
pattern.
2. Indicate the areas of concern (causes for replacement) on the test pattern with checkmarks or by
circling them.
2
 Packaging procedure
 Items to prepare SPC-0369 Cleaning solution 200 for solvent kit

Usable cleaning liquid:MP-M013237 FlushingLiquid pre-fill up solution for solvent INK
Syringe SS-20ESZ
Tube TP-SX 3×5equivalent, The length is appropriate.
3
Filter HDK1E-0048 Filter, or LCF-12100 Filter (10μm)
1. Print a nozzle check pattern.

Use photo paper so that missing dots can be identified.
2. Mark locations where a failure has occurred.

Write down the serial number of the head, to show clearly that
the test pattern and head match exactly. 4
Mark 5
3. Replace the head (Refer to “6.2.2 Head Unit”)
 Do not throw away the replacement head packag-
6
ing materials and fittings, as you will need them
when sending back the head that required replace-
ment.
 When washing, replacing the air purge valve with
the fitting makes it easier to use the jig.

Rev.
4. Remove ink from the head that requires replacement with

syringe.
5. To prevent from drying out, fill up the washing liquid to the

head.
0
 To prevent the liquid from drying out, make sure
1
that the Washing Liquid should not be discharged
(the inside of the head should be filled with Wash-
ing Liquid).
 The goal should be to just have some liquid starting
to drip from the nozzle, being careful not to inject

SWJ-320S series offer following 2 ways to adjust the print head.
1)Adjust slant, stagger, and position at the same time by [AVERAGING ADJ.].
2
<Advantages>
 No feed is in, and thus no substantial effect of media’s skew.
 Given that slant, stagger, and position can be adjusted at the same time, adjustment in short time is
possible.
 Image quality is better in Bi-d printing rather than adjusting slant by [SLANT ADJUST]
<Disadvantages> 3
 Image quality is deteriorated in Uni-d printing rather than adjusting slant by [SLANT ADJUST]
2)Adjust slant, stagger, and position separately by [SLANT ADJUST]/[STAGGER ADJUST]/ [POSI-
TION ADJUST].
4
<Advantages>
 Image quality is better in Uni-d printing compared to adjusting slant with [AVERAGING ADJ.]
5
<Disadvantages>
 In [SLANT ADJUST], maladjustment may occur by the effect of media skew.
 Slant, stagger, and position cannot be adjusted at the same time, and thus it takes time.
 Image quality is deteriorated in Bi-d printing compared to adjusting slant with [AVERAGING ADJ.]
 The development department recommends adjustment by [AVERAGING ADJ.], which adjustment

4.2.2 [HEAD ADJUST] Carriage base tilting 1.0
 Outline
For the tilt adjustment procedure using the head adjustment jig of this machine, the adjustment is carried out in the
manner that it moves the front side of head unit left and right, pushing the back side of head unit to the contact end
surface.
The head unit itself has been so adjusted that no tilting occurs if the head unit is mounted, pushing the unit to the con-
tact end surface.
1
Therefore, at shipped, it is in the condition that the right side of head unit is pressed to the contact end surface.
The head unit is possible to tilt in the right direction but not possible in the left direction since it is in the condition
that the head unit is pressed to the right side.

 Outline
This chapter describes the troubleshooting for SWJ-320S.
 Rough Identification of the Source of the Trouble

At the beginning of troubleshooting, it is necessary to identify roughly which functions the trouble relates to.
1
Problems can be roughly classified into those that relate to the printer itself and those that involve the connection
between the printer and the host computer.
 Problems with the printer itself

The cause of the trouble can be identified by executing appropriate functions or using test functions.
 Problems concerning the connection to the host computer

Hardware: Broken wire or faulty contact of cables
Software: Transmission by improper application setting 2
In the standard setting of SWJ-320S, priority is given to the host computer.
Check the settings on the host computer to see if there is any improper parameter setting.

6
Rough identification of error source
Execute appropriate functions or use test
functions of SWJ-320S
7
Do the
above functions operate No
normally?
Yes
Troubles on the host computer side
8
If this troubleshooting cannot correct the trouble, check to see if the same trouble occurs
with another host computer (if possible).

7.1.1 Concerning Errors and Malfunctions 1.0
 Checking Procedure
This section describes troubleshooting procedures for the problems for which error messages are displayed.
1.Identifying the error category
The causes of errors can be classified into the following categories:
 Handling error on the host computer side

1
 Trouble on the host computer side
 Trouble with the Interface Cable
2
 Printer handling error
 Printer mechanical trouble
 Printer hardware trouble
 Printer firmware trouble
2.Initial action
3
Refer to the error message, and judge whether the trouble lies on the host computer side or on the printer side.
 Has any of the interface conditions (printer model setting, command, communication conditions, etc.) been
changed? 4
 Does the trouble occur under specific conditions?
 Does the same trouble occur repeatedly?
3.Failure on the printer side

5
Take the following steps to repair the printer.
6
 Uploading and checking of parameters
 Reinstalling of firmware
 Checking of FFC and cable connections
 Replace the defective part (sensor, etc.) or make the necessary adjustment.
 Replace the PCBs. 7

4.Repair at the factory
8
If the error recurs even after the corrective measures specified here are taken, return the printer to the factory of
MIMAKI for repair.

7.2.2 Checking of the cap leak 1.0
 Outline
Check whether airtightness of the cap is enough when nozzle missing occurs due to ink suction defect.
 Work procedures
 How to see if suction defect occurs
1. Check that piping between the cap and the suction pump is surely connected.
1
Tube between cap and suc-
tion pump
2
Suction pump
3
2. Turn ON the power supply, and make the status capped.
3. Remove the top edge of the tube between the suction pump and the waste tank, and connect the syringe.
4
Syringe
Tube between suction pump

and waste tank 5
4. Pull out the connected syringe slowly. As a reference, pull out about one scale per one second.
(If you pull out it swiftly, you cannot check leakage.)
6
 Do not push the syringe. It may push foreign object into the nozzle, and it may cause nozzle defect.
 Criteria for judgment

OK: If you feel a good response when pulling the syringe (You can feel that you are pulled back.)
7
The cap is OK. Check other supply system.
NG: If you do not feel a good response when pulling the syringe (You can pull easily.)
8
Cap leakage occurs. Check the cap and the cap position.

7.2.3 Print Head / HDC PCB Assy Damage Check 1.0
 Outline
This is the test to check whether there is abnormality in the print head and head drive unit of the HDC PCB assy.
(mainly COM line), also to verify whether the head power (VH, +3.3V) has not been short circuited with GND.
If the errors (below) that are possible failure of the head / HDC PCB assy. occur, perform this check in order to isolate
the problem.
1
Error12e Head Failed
Error15f HEAD DRIVE HOT
Error181 PCB H21
Error189 COM VOLT
Error18e FLS NOT COMP
Error18f OFFSET START
Error18f OFFSET END
2
Error108 HD CONNECT[123456]
Error108 HD THERMIS[123456]
3
Error707 !HD Heater disconnection
If there is no abnormality in this check but the error still remains, a bug in the communication system is considered.
In that case, connect and disconnect the cable, exchange the cable, or exchange the PCB's.
The power is turned OFF in the order of the SUB power switch → MAIN power switch, and unplug the
power cord.
It is very dangerous if accidentally the sleep function is activated during work process. 4
Also, it may damage the PCB assy when the charge is remaining.
In addition, do not touch by mistake the high voltage portion of the PCB assy. There is a risk of electric
shock.
 Work Procedures 5
1. Referring to left, measure the resistance between the
Measurement points COM+GND in the tester in a state of removing the head and
73 HDC PCB assy.
6
73
Apply the positive lead of the tester to COM signal and the
73
negative lead to GND. Normally it is considered in the order
73 of approximately 25?35kΩ.
If the resistance value is as low as 0 to several Ω, the HDC
73
Measurement 73 PCB assy is considered to be damaged. Replace the HDC
7
method between PCB assy.
COM+GND
73 COM:TP3,4,5,6 (Head 1), TP7,8,9,10 (Head 2),
73
GND: Heat sink portion and screw portion

3. Refer to left, measure the resistance value between the head
Portion to check the head power (+3.3V) short
power (+3.3V) and GND. It is considered normal if it is approx-
imately 300Ω or more.
PCB assy. is considered to be damaged. Replace the HDC
3
PCB assy.
Head power: the through-hole near FL4,
Between the through-hole (+3.3V) near C224 and GND
4. Connect the head and the HDC PCB assy and measure the resis-
tance value by a tester in the same manner as steps 1 - 3.
4
It is normal if the resistance value between COM+GND is
about 25 - 35kΩ.
5
It is normal if the resistance value between the head power
(VH) + GND is 40kΩ or more.
It is normal if the resistance value between the head
power(+3.3V) + GND is 300Ω or more.
If the resistance value is as low as 0 to several Ω, the head is
considered to be damaged. Replace the head.
If there is the adhesion of ink or the cleaning solution to the
6
head cable, also exchange that head cable.
 If there is an abnormality in the resistance value
7
even one location, there is a possibility that the
head or the HDC PCB assy. might corrupt.
Exchange the head or the HDC PCB assy.
 When the power is ON in a state where the head or
HDC board is damaged, it would repeat failure
again.
