6 Troubleshooting

6-1 START AND END POINTS DO NOT MATCH

NO CHECKING POINT ACTION REFERENCE OUTLINE

1

Blade Offset doesn't match with offset set in the

machine

Match Offset User's Manual

Blade used on the machine has offset and therefore, tip is shifted from its center. When the offset setting done on the machine doesn't match with the blade offset, offset correction won't be done. Therefore, the starting and ending points won't match because the direction of the blade slightly shifts from the correct direction.

2 Blade Holder is set loose

on Carriage Secure the Blade Holder User's Manual When blade holder is set loose on carriage, the blade tip becomes very shaky when cutting and results in distorted figure.

3 Blade tip is wearing out Replace the Blade User's Manual

When blade tip wears out, offset will be changed. Therefore, as same as 1, the starting and ending point won't match especially when cutting circles.

4 Scratch in Cutter Protection

Replace the Cutter Protection

[3-6 Cutter Protection Replacement]

Cutter Protection is where the blade lands for cutting. If there is scratch on the Cutter Protection, blade doesn't rotate smoothly and therefore, starting and ending point won't match.

5

Bearing inside Blade Holder doesn't rotate

smoothly

Replace the Blade Holder

There are bearings inside the blade holder. When the bearings don't rotate smoothly, direction of the blade slightly shifts from the correct direction and therefore, starting and ending points do not match.

6 Carriage ASS'Y is loose Fix Tool Carriage ASS'Y again

When Carriage ASS'Y is loose, the cutting is unstable and starting and ending points do not match.

7 Holder part of Tool Carriage is loose

[3-1 Tool Carriage Replacement]

When Holder part of Carriage is loose, the cutting is unstable and starting and ending points do not match.

8 Tool Height is not correct Tool Height Adjustment [4-4 Tool Height Adjustment]

When Tool Height is not adjusted, blade hits the Bed strongly and bounces. Therefore, the cutting at the very beginning won't be done and cause the starting and ending points to be shifted.

9 Tool Pressure is not correct

Tool Pressure Adjustment

[4-5 Tool Pressure Adjustment]

When Tool Pressure is not adjusted, blade hits the Bed strongly and bounces. Therefore, the cutting at the very beginning won't be done and cause the starting and ending points to be shifted.

And also, when the Tool Pressure is set too high by the user, the blade offset changes because the blade tip goes deep into the vinyl. Therefore, the starting and ending points will be shifted.

10 Motor Gear is meshed too

loose Adjust Backlash

When Motor Gear is meshed too loose, Carriage and Grit Roller will be driven unstable and results in starting and ending points to shift.

6-2 STITCH CUT

NO CHECKING POINT ACTION REFERENCE OUTLINE

1 Blade tip is wearing out Replace the Blade When blade wears out, it will be caught by the vinyl and results in stitch cut.

2 Scratch in Cutter Protection

Replace the Cutter Protection

[3-6 Cutter Protection Replacement]

Cutter Protection is where the blade lands for cutting. If there is scratch in the Cutter Protection, blade is caught by the vinyl because it sticks deeper into the vinyl and results in stitch cut.

3

Bearing inside Blade Holder doesn't rotate

smoothly

Replace the Blade Holder

There are bearings inside the Blade Holder. When the bearings don't rotate smoothly, direction of the blade slightly shifts from the correct direction and therefore, it will be caught by the vinyl which results in stitch cut.

4 Carriage ASS'Y is loose Fix Carriage ASS'Y again

When Carriage ASS'Y is loose, the cutting is unstable and results in the stitch cut.

5 Holder part of Tool Carriage is loose

Fix Holder part of Tool Carriage again

When Holder part of Carriage is loose, the cutting is unstable and results in the stitch cut.

6 Tool doesn't move up/down smoothly

Replace the Tool Carriage

[3-1 Tool Carriage Replacement]

When Tool doesn't move up and down smoothly, blade sometimes hits the Bed strongly and bounces which results in stitch cut. In most cases, stitch cut at the beginning is caused by this reason.

7 Tool Height is not correct Tool Height Adjustment [4-4 Tool Height Adjustment]

When Tool Height is not adjusted, blade hits the Bed strongly and bounces which results in stitch cut. In most cases, stitch cut at the beginning is caused by this reason.

8 Tool Pressure is not correct

Tool Pressure Adjustment

[4-5 Tool Pressure Adjustment]

When Tool Pressure is not adjusted, blade hits the Bed strongly and bounces which results in stitch cut.

9 Solenoid Driver IC is

broken Replace Main Board

When Solenoid Driver IC breaks, sometimes high pressure will be generated. In this case, blade hits the Bed strongly and bounces which results in stitch cut.

6-3 MEDIA SHIFTING

NO CHECKING POINT ACTION REFERENCE OUTLINE

1 Media is not set straight to

the machine Setup Media again User's Manual

The most effective measure against media shifting is to set the media straight to the machine. Small tilting of the media when setting it up could result in big shifting especially doing long print. It is recommended to setup the media by adding tension towards front and check the shifting by prefeed function before actually start cutting.

2 Pinch Roller is wearing out Replace the Pinch Roller

[3-5 Pinch Roller Replacement]

When pinch rollers wear out, power to hold the media will be weakened and results in media shifting. Referential time for replacement of pinch roller is 24 months.

3 Pieces of Media Cleaning

When dust such as pieces of media is stuck to the feeding place, the media makes contact with the dust during the cutting and it results in media shifting.

4 Grit Roller is dirty Clean the Grit Roller

When dust such as pieces of vinyl is stuck to the grit roller, power to hold the media will be weakened and results in media shifting. Use brush to clean the Grit Roller.

5 Screw fixing the Link Plate is loose

Secure the screw fixing the Link Plate

When the screwfixing the Link Plate(which connects the Sheet Loading Lever with the Pinch Roller Shaft) is loose, the pinch roller doesn't push the grit roller with the correct pressure and resluts in media shifting.

6 Fan revolution [6-5 Fan Revolution]

When Fan is not rotate correctly, it doesn't suck the media to the Apron and the media lifts up at the Bed and results in media shifting.

7 Motor Driver IC is broken Replace Main Board

Motor Driver IC is a chip to supply the current to drive the motor.

When it is broken, motor doesn't supply the correct current and the motor doesn't move correctly and results in media shifting.

6-4 TOOL UP/DOWN ERROR

NO CHECKING POINT ACTION REFERENCE OUTLINE

1 Cable is not connected

correctly Connect the cable again When there is a bad contact on the connector or cable, the signal is not sent and cause tool up and down error.

2 Tool Pressure is not correct

Tool Pressure Adjustment

[4-5 Tool Pressure Adjustment]

When Tool Pressure Adjustment is not done correctly, there is a case the tool doesn't down.

3 Cut-line in Carriage Cable Replace Carriage Cable

When there is cut-line in the carriage cable, the current is not supplied from Main Board to Solenoid and the tool doesn't up/down.

4 Load on the Carriage

up/down movement Replace the Carriage [3-1 Tool Carriage Replacement]

When the media is jammed, the carriage hits the jammed media and results in the position of the solenoid shifting. The

mechanical load by rubbing the coil and bobbin cause the tool up/down error.

5 Cut-line in solenoid coil Replace the Carriage [3-1 Tool Carriage Replacement]

When there is cut-line in solenoid coil, there is no function as electrical magnet because of no current and results in tool up/down error.

6-5 FAN REVOLUTION

NO CHECKING POINT ACTION REFERENCE OUTLINE

1 Bad Contact in connector Connect the connector again

When there is bad contact in connector, the signal doesn't pass and results Fan doesn't rotate.

2 Main Board is broken Replace Main Board

Fan is controlled by the Main Board. If the Main Board is broken, it doesn't control correctly and cause the Fan rotation error.

3 Fan is broken Replace Fan

Fan doesn't need to replace normally, however there is a possibility the motor doesn't rotate because wearing out.

Therefore, if there is no problem in the above, replace the Fan to check.

6-6 MOTOR ERROR

NO CHECKING POINT ACTION REFERENCE OUTLINE

1 There is a dirt in teeth of

Drive Gear Clean Drive Gear When there is a dirt in the teeth of the Drive Gear and it cannot rotate, the Motor Error occurs.

2 Motor Gear is meshed too

tight Adjust Backlash When Motor Gear is meshed too tight, it cannot rotate, and results in the Motor Error.

3 Bad Contact in connector Connect the connector again

When there is bad contact in connector, the signal doesn't pass and results in the Motor Error.

4 Broken / life of the Motor Motor Replacement

[3-3 Carriage Motor Replacement/3-4

Grit Motor Replacement]

When the Motor is broken or reaches its life, the Motor cannot obey the order from the CPU and it results in the Motor Error.
