Is the blade chipped ? If it is, replace it with a new one (see “4-1 Installing a Blade” ).
Check if there are any dirty deposits on the
blade.
If dirty, remove and clear the blade.
Are blade speed, blade compensation, and
cutting speed appropriate for the sheet
being cut?
Perform a cutting test and use the display menu to select the appropriate values
(see “4-5 Cutting Test (How to Adjust Blade Force and Blade Extencion)” / “8
Display Menu Lists” ).
Is a thick material being used? When using a thick material, change the display menu setting from "NORMAL" to
"HEAVY."
When using a material with a width greater than 762 mm (30"), lower the middle
pinch roller at a position near the center of the material.
Is a wide material being used?
Are the blade and blade holder installed
correctly and securely ?
Install these so that there is no looseness (see “4-1 Installing a Blade” ).
The material is not cut properly
Is a material with sprocket holes being
used?
If a material with holes for sprocket feed is being used, placing the pinch roller
above the hole portion may cause the material to slip. Be sure to set the pinch
roller over the material to the inner side of the hole portion.
The Material slips away from the pinch rollers during the cutting process
If a flat material (such as a standard-size
material or piece material) has been
loaded, has the “PIECE” setting been
selected for the material type?
When loading the material, select “PIECE” for the “SELECT SHEET” display
menu (refer to “4-2 Loading the Material”).
Is the material being cut blocked at some
position?
Make sure that the left and right edges of the material do not touch the inner
surfaces, front cover of the CM-500/400/300 during cutting. Such contact may not
only damage the material, but could also make normal material advancing
impossible and cause the material to slip.
Is the material being cut blocked at some
position?
If the front edge of the material you are working with is at an angle, cut off the
odd-shaped part to make it straight, then align it so that it is parallel with the grit
roller.
If the material is fed for a long distance, the material will be less likely to slip out
of alignment if the pinch rollers are moved inward slightly (5 to 25 mm).
When a roll material is loaded, use the display menu “AREA” function to feed a
material by the length to be used (ensure a small margin by setting a length that is
about 0.1 m longer than the cutting data), make sure the pinch rollers are still in
contact with the material (not off the left or right edges, or on the edges), and then
cut.
If the material is pulled while cutting it is more likely that material misalignment
and motor errors will occur.
Does material strike the front cover during
cutting?
If the edge of the material strikes the front cover, causing it to open, the message
"CLOSE COVER" appears on the display and cutting pauses.
Close the cover to resume cutting.
Cutting stops partway through
