5.3 Printing the Test Protocol
The integrated thermal printer allows printouts of the test protocols to be
created conveniently on-site, immediately after the test; protocols can
also be printed at any later point in time. The protocol shows all data
obtained during the test (see printout on page 37). To print the test proto-
col, activate the thermal printer by pressing the ‘PRINT’ button. It is loca-
ted on the internal control panel. During the printing process the control
lamp will show green. When printing is finished, detach the protocol by
tearing it against the tear-bar. If the green light is flashing and the thermal
printer does not start printing after pressing the ‘PRINT’ button, this is usu-
ally due to the absence of paper. In this case, follow the instructions
below to insert a new roll of paper. The button for the paper feed is
located on the left of the green control lamp.
5.4 Changing the Paper
A flashing green control lamp signals the absence of paper. To open the
paper tray and replace the paper roll, press the button on the green control
lamp. Lift the cover and insert the new thermal paper roll (57 mm wide
and 25 mm long) with the coated side facing outwards. One roll of paper
will print approximately 100 printouts. Unroll approximately 10 cm of
the edge of the paper and hold it up, while closing the printer by gently
pressing the cover on both sides. Detach the protruding end of the paper
by tearing it against the tear-bar. The printer is now ready for use again.
An ink ribbon is not necessary for the thermal print method.
Use only thermal paper; the coated, heat-sensitive side must face
outwards. Suitable paper rolls can be obtained in most office supply
stores, or ordered at TERRATEST GmbH.

If you intend to store printouts for an extended period of time, make sure
that the thermal paper is not exposed to direct sunlight or temperatures
over 30°C. Thermal paper ages relatively quickly, so ensure to make
copies on normal paper.
