Ribbon Breaks
Problem Action
Ribbon breaks may be
caused by one of the
following issues: Check that the encoder matches the
substrate speed correctly, otherwise the
ribbon may be dragged out of the printer
and eventually break.
For IM printers:
Check that the printer is printing whilst the
substrate is stationary.
For CM printers:
Check that the energy to the print head is
not too high.
When increasing the level of ribbon
economy, reduce the Print Head Pressure
value setting to compensate for extra
friction forces that are applied on the
ribbon during printing. Reducing the Print
Head Pressure value reduces the friction
forces that can cause the ribbon to crease,
stick to the substrate or break.
The print head carriage
does not move A stepper motor, drive belt and linear slide
are used to move the print head. If the
head does not drive, check the following:
The drive belt and drive pulleys.
Are the stepper motor connections
correct? Check the condition of the linear
slide. With the power to the unit turned off,
is the print head free to move along the
slide?
If the fault persists, board replacement
may be required.
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).
Roller alignment Pick up the printer and rotate the ribbon by
hand by winding on the rewind spool or
cassette. Look at the ribbon that goes
around the rollers and visually note
whether the ribbon is pulling to one side. If
this is the case the rollers may be out of
alignment. Contact the supplier.
