GRAPHTEC FC4200-60 - The Coordinate Axes Cannot be Correctly Aligned

9 – 8
9.2.3 The Coordinate Axes Cannot Be Correctly Aligned
Solution
Ensure that the detection area is free
of foreign matter or plotting.
• Firmly secure the medium so that it
will not come loose.
• Use a medium without any wrinkles,
creases, or folds.
Use a white medium.
Print the registration marks using
black ink.
Print clean registration marks with a
line width of at least 0.3 mm.
Ensure that no light from an external
source irradiates the vicinity of the mark
sensor.
Symptom
During automatic registration mark
alignment, the MARK SEARCH
ERROR message is displayed or the
coordinate axes cannot be properly
aligned.
Cause
There is foreign matter or
plotting on the area where
the mark sensor passes.
The medium is loose or
wrinkled where the mark
sensor passes.
The medium is not white.
The registration marks are
not printed using black ink.
The lines of the printed
registration marks are too
thin or are not cleanly printed.
Strong light is irradiating the
vicinity of the mark sensor.
If none of the above solutions are feasible, perform registration mark
alignment manually.
