Important Safety Information

Safety Instructions
General and Personal Safety Precautions
[PERSONAL SAFETY]
For personal safety, observe the following general precautions:
A second person should be available to disable the system in an emergency.
Wear appropriate protectIIIe gear that fits comfortably.
Do not wear loose-fitting clothes. If you are wearing a long-sleeved shirt, fold the
cuffs up your arm.
Never wear gloves close to moving parts.
Necklaces, ties and scarves should be tucked inside shirts.
Long hair should be covered.

[ELECTRICAL TOOL SAFETY]

When using Electrical Tools make sure to:
Use tools that are in good operating order. Any tool that appears electrically or
Mechanically faulty must be labeled and sent immediately for repair.
Make sure that you are electrically insulated when using electrical tools. Wear
rubber-soled shoes and stand on a dry surface.
If, during the use of electrical equipment, you feel an electrical discharge (e.g. a
tickling sensation on your skin) immediately stop using that tool. Label it, and send it for
repair.

[GENERAL SITE SAFETY REQUIREMEN TS]

Fire extinguishers must be in working order and within easy reach.
The main power supply switch must be easily accessible.
The system site must be suitably illuminated from all sides.
Before operation, carefully read the warning labels on your Cutting plotter unit as
well as the cautions and warnings in this manual.
Connect the Cutting plotter to a properly grounded power outlet. Make sure the
voltage level of the Cutting plotter matches that of the power source.
Don’t dissemble the unit while system power is on since the power supplies inside
contain high voltage.
Never leave the machine unattended during operation.
Follow the instructions on maintaining and cleaning your system. Not only will this
enable you to utilize your machine efficiently, but it will also ensure that your
machine runs safely.

Troubleshooting

Maintenance Diagnostics
This section provides maintenance diagnostics as troubleshooting aids. This diagnostic feature is to check hardware to find out
which components are good or defectIIIe. Using this diagnostic test facility enabl es the diagnosing of the hardware components.

How to Begin Maintenance Diagnostics

How to Begin Maintenance Diagnostics
To start the Maintenance Diagnostics facility hold down the On/Off Line button and CUT TEST button while turning on the
cutter. The following sub-sections will explain the function of each maintenance diagnostic sequence.

46
Diagnostic Test for SRAM and DRAM

This test provides the ability to diagnose the SRAM and DRAM. If these two components are bad, replace them. Otherwise the
cutting plotter will not work properly.

Diagnostic Test for Lever Sensor

This feature diagnoses the lever sensor. If the sensor is faulty, the cutting plotter cannot sense that the pinch rollers have
been lowered or not. If the lever sensor is down, you will see a lift the lever message on the LCM. If the lever is up, you will see
a lower the lever message on the LCM. You can use the ON/OFF LINE KEY to abort your test when y ou have finished
the lever sensor test.

Diagnostic Test for Media Sensors
This test is to diagnose the media sensors. If they are fau lty, the cutting plotter c annot detect the media length correctly. You
can see the current front and rear sensor condition, you can turn it on or off to see if sensors are out of order or not.

48
Diagnostic Test for Width Sensor

If the sensor is faulty, the cutter cannot sense the media width correctly. Refer to the maintenance chapter to replace it. You
must first move the tool carriage to the rightmost position; the lever must be down to do this. Once this is done please move
the tool carriage to left. Be careful when moving the tool carriage close to the pinch roller, since the message changes
quickly when sensor is between on and off.

Diagnostic Test for Motor Encoder and Tool Holder Encoder
This feature provides the ability to diagnose the X a nd Y motor encoder and tool holder encoder. If the encoder is
defective, the cutting plotter cannot work properly. To check if the encoder is bad or good, you can apply a slight force to
the tested part (such as a drum, the tool carriage or the tool holder) then examine the readings. If the encoder reading
changes dramatically, the encoder is bad. Refer to the maintenance chapter to replace the motor or tool carriage.

X Motor Encoder Test

50
Y Motor Encoder Test

Diagnostic Test for Tool Force (VCM)

This test is to diagnose the VCM. If the VCM is bad, the tool carriage cannot perform the up/ down action that generates the
tools force on the material.

Note: VCM means Voice Coil Motor that gen erates tool force

Diagnostic Test for Motor Movement

This feature is to diagnose the X and Y motors and drIIIers. If you encounter a motor movement problem, try to change the
main board first. If the problem still re mains after replacing the main board, try replacing the motor.

This feature provides the ability to diagnose RS-232 interface, and checks communication between the cutter and
computer.

Note that: Do not press keys too quickly, or it may cause an overrun error

53
Problems and Solutions
This section discusses typical problems you may encounter while operating the cutting plotter and offers you possible
solutions

The line quality is not good enough at the corner or the end point.
Causation and recovery:
Forgetting to fasten the tool (Fasten it.)
The blade is worn. (Change it.)
The offset value is wrong. (Correct the offset value.)
Media is not flat enough. (Reload the media.)
Media is wet. (Change it.)
The quality of media is not good enough. (Change the media.)
Drum or pinch roller is worn. (Change the drum set or pinch roller.)

The position of pinch roller cannot be detected so that the media width cannot be determined correctly.
Troubleshooting Causation and recovery:
Forgetting to lower the pinch roller. (Enable the pinch roller and push the lever forward to lower down the pinch roller) The
orientation of the width sensor on the carriage PCB is not correct. (Adjust the orientation of the carriage PCB)
The position of the width sensor on the carriage PCB is too high to sense the block bar on the pinch roller. (Lower the
carriage PCB)
Flat cable is broken. (Change it.)
Width sensor is damaged. (Change it.)
Carriage PCB set is damaged. (Change carriage set.)

The function of “Set New Origin” does not work.

Causation and recovery:
The origin point will be set by pressing the ENTER button when the Puma is in an OFFLINE state, only then will the LCD
display the distance between the new and old origin.
