Encoder
(CM printers only)
Check that the encoder is rotating
freely. The CM printer, it will not print
unless the encoder is moving.
Check that the encoder signal is
sending a signal back to the controller.
Ribbon Drive Problems If the print contrast is too high or the
print speed too low, the ribbon can be
weakened and break. This can be
eliminated by reducing the contrast or
increasing the speed.
The ribbon rewind is not taking up the
waste ribbon correctly. Check that
there is no interference between the
accumulated wasted ribbon and any
other part of the printer body. Ensure
that the waste ribbon spool is gripping
the core firmly.
Missing front edge of the print
out Head down time is too short. Increase
the head down time step by step in 'run
settings' until the front edge is
included. Should the controller report
that the Y-offset is too short, increase
its value.
The reaction length is too long, thus
creating an overlap between two prints
on the used ribbon.
Rear edge of print out is
missing Head up time is too long. Decrease the
time in run settings.
There are unprinted lines in the
print Clean the print head using Cleaning
Pens (P/N VPR0223),
Cleaning Fluid (P/N WJ-111) and Print
Head Cleaning Wipes (P/N MT25215).
Perform a thorough cleaning.
Any scratches on the rubber platen or
rubber roller affects the print.
Thoroughly clean the rubber platen and
rubber roller. If scratches remain on the
platen or roller, replace one or both
accordingly.
One or more defect print dots are
present. Move the design in position x
to an area where the defect dot is not
being used. If this is not possible,
change the print head.
