The machine might be improperly grounded, make sure central line of the power source grounded
。
Q6: Why the job feel not smooth with sharp-angle raised when plotting?
1. The protruding length of knife top is too long, please adjust it as required.
2. The knife is worn, replace it.
Q7: Why the plotter cuts or draws a line before plotting?
Because the machine improperly exited from previous operation, there is still knife-dropping instruction existing in the memory of
plotter. To resolve it, power off the machine and turn it on again.
Q8: Why no or black rows displayed on LCD panel?
1. In case of no display, check whether the power work well.
2. If black blocks are displayed, check whether voltage is at required level. If the troubles remain after the above operation, please
contact maintenance center.
Q9: Why some characters can’t close in strokes when it is plotting?
Because the knife of the plotter is eccentric knife with a eccentric value, to resolve it, set“closing compensation”in the software. For
example, With Artcut software:
1. Click“plotting output”once, a plotting output picture will pop up.
2. Click“set”once, a picture of setting plotter will pop up.
3. Click“compensation setting” a dialog box will pop up.
4. Select closing compensation, adjust the value to required level, generally the value is set to be 0.5.
Q10: Why the plotter has missed some pave of letter when cutting?
1. Check the machine if it presses enough.
2. Reinstall the software.
3. Chook the head of the knife.
4. If the problem is still existence, please contact with repair center.
Q11: Why the plotter starts low-speed after start-up?
Because paper sensor fails to detect the fore end of paper. When feeding paper make fore end of paper cover hole of paper sensor,
and then perform another automatic paper testing.
Q12: Why some nicks deep and other shallow when cutting?
The cutter employs upscale soft PVC materials as knife strip cushion to protect knife. But after using for long period, it may
produce some tracks therefore roughing the stripe cushion, so some nicks become deep, while some become shallow. To resolve
it replace a stripe cushion. If is not so worse, adjust knife pressure (some 120 -150).
Q13: Why the plotter has no response when it is outputting?
1. Check the properties of COM port, baud rate, flow control, parity check and data bits both on PC (device manager) and
Software (Artcut).
2. Check all cables, plugs, fuse and power.
3. PC or Software may affected by virus, remove or reinstall.
Q14: Why an instant-glue paper can’t be peeled off?
1. Perform trial run prior output, adjust press to appropriate level.
2. Check whether the knife worn too much, or whether the knife tip is broken. For new ones the nick is thin in the instant-glue, while
for old ones the nick is thick and impressive. To resolve it replace it with a new knife.
Q15: What steps need to be taken when cutting big characters?
1. When cutting big characters, the system can automatically setup pages, you can cut a big character in several pages, but it is
notable that the setting of output width shall be conformed to the width of instant-glue in addition, when cutting big characters
and output it, you should widen pages or set seaming distance.
2. When you use the special wide machine to cut the big characters, especially the long big characters before cutting input, you
shall instead the paper first look careful the paper if the paper deviates then deviate the big characters into some pouts to input, it
can make sure it won’t deviate and waste paper.
