3.6 Ribbon Tension Adjustments
(CLP 2001, 6001, 6002, 6401)
When the ribbon slips or wrinkles during printing, adjust the ribbon tension. The
printer has already been factory set with the ribbon width of 114 mm. When
using ribbon with a different width, adjust it according to the following procedure:
a) Hold the ribbon roll with one hand so that it does not turn.
b) Slightly push the knob toward the ribbon roll with the other hand and rotate
the knob until the stopper comes to the desired position.
c) Gradually release the knob so that the stopper fits in the groove on the knob.
Set values to each ribbon width:

d) After printing, check for ribbon wrinkle or slippage. If it occurs, adjust it
further according to the following procedure:
(1) When the ribbon wrinkles, the tension on the ribbon winding section
should be increased.
(2) When the ribbon slips, the tension on the ribbon feed section should
be decreased. If the problem is not resolved even when the tension
on the ribbon feed section is set to 3, the tension on the ribbon
winding section should be increased.
If ribbon problems are not resolved, consult our service personnel.
