The paper sensor is a laser distance sensor, and is using an visible laser beam to check the distance to
the paper.
If the distance is long (the paper is close to the floor) the feeding speed is slow (or it will stop com -
pletely) and if the distance is short, the feeding speed is high. This will ensure that there is a constant
slack of paper between the Paper Roll Feeder and the printer.
The paper is clamped between the feeder rolls with a press air cylinder. After a short period of stand
still, the pressure on the feeder rolls will be released. This is done to prevent deformation of the paper.
Put the shaft in the center of the roll, and ensure that the shaft is approximately in the centre sideways.
Fasten the shaft. The roll must be placed so that the paper is rolled off at the top. (See figure).
Place the paper roll with the shaft already fastened just behind the Paper Roll Feeder. Lift off the cor-
rection roll with the friction bars and place aside. Use the crank to lower the roll lift until the lift is
below the shaft in the roll. Move the roll forward, make sure that the shaft is situated just above the
notches, while turning the crank to raise the roll lift. Turn the crank until the roll is lifted above the
floor. Put the correction roll with the friction bars on top of the paper roll like on the figure below.
Remove and throw away the first revolution of paper on the paper roll (to get rid of e.g. sand, dust and
dirt after rolling the paper roll on the floor).
The paper line must go in between the friction bars and the correction roll. Ensure that the friction bars
is resting on top of the roll.
Now the paper must go through the feeder rolls. If turned on, the motor will feed some paper, and the
paper can be inserted into the printer.
