Print Quality and Print Head
Problem Action
No Information is Printed If the printer appears to be operating
correctly but no data is printed, check
the following: Is a valid message
selected?
Check the print speed and contrast
values are at appropriate levels for the
thermal ribbon and substrate.
Is the print head coming into full
contact with the print platen / roller
across its full width? Is the correct
ribbon loaded with the inked surface
away from the print head and is it
advancing correctly?
For CM printers, the encoder signal
may not be providing the correct speed
information.
The print head may be faulty.
Ensure that the printer is ready to print,
as the print head retracts when the
printer is not ready (for example, if no
design has been selected).
Poor Print Quality The most common cause of poor print
quality is a dirty print head. Clean the
print head using Cleaning Pens (P/N
VPR0223), Cleaning Fluid (P/N WJ-111)
and Print Head Cleaning Wipes (P/N
MT25215). Wipe the print head and try
again. Take care not to damage the
print head during cleaning. Always
allow the print head to cool prior to
cleaning.
A dirty, worn or badly misaligned print
platen / roller. Produce a full size test
print to establish the quality of the
print.
The ribbon is not advancing correctly.
Clean the ribbon rollers and check that
the ribbon is loaded correctly.
The ribbon is not fitting correctly over
the top of the print head guide roller(s).
