When Blade Holder is set loose on Tool Carriage, the
blade tip becomes very shaky when cutting and results in
distorted figure.
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 and results in distorted
figure.
When blade tip wears out, offset will be changed.
Therefore, it results in distorted figure like the way 2.
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 results in
distorted figure.
When holder part of Tool Carriage is loose, direction of
the blade slightly shifts from the correct direction and
results in distorted figure.
When the Tool Carriage is loose, the blade tip becomes
shaky and results in distorted figure.
When Motor Gear is meshed too tight or too loose, Tool
Carriage and Grit Roller will be driven unstable and
results in distorted figure.
Media Flanges are fixed by the stoppers. If the
stoppers are not fixed, roll shifts to left and right
during media feeding and results in media shifting.
When the flanges are not fully inserted to the
media tube, media will be fed eccentric and results
in media shifting.
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 printing.
When dust such as pieces of vinyl is stick to the
grit roller, power to hold the media will be
weakened and results in media shifting. Use brush
to clean the Grit Roller.
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.
When Grit Roller becomes loose, feeding amount
between left and right edges will be different and
results in media shifting.
