Adjustment Knobs
The print unit is fitted with two adjustable spring packages, which
allow the pressure to be set by turning the knobs:
• Turn the knobs clockwise to increase the pressure.
• Turn the knobs counter-clockwise to decrease the pressure.
At each quarter of a turn, the resistance increases and a clicking
sound can be heard.
The required pressure may vary between paper qualities of different
thickness. Generally, thicker face materials require more pressure
than thinner.
Make a rough adjustment like this:
• Turn both adjustment knobs clockwise as far as they go to
maximum pressure.
• Release the pressure of the inner spring package by turning the
knob 2

turns counter-clockwise (9 clicks).
• Release the pressure of the outer spring package by turning the
knob 2 turns counter-clockwise (8 clicks).
Fine-adjust the pressure by turning the outer knob, while retaining
the setting of the inner knob. If the desired result cannot be obtained,
increase or decrease the pressure by turning both knobs a quarter of
a turn in the same direction, then fine-adjust the outer knob.
