Paper ribbons installation procedure for Euro-2100TE (numbers according to Figure 2.7):
Press the control button (1) to flip the tape cover (2) open. Take out the paper tape separator (3) along with
empty paper reel, remove it and install new paper tape reel (5). Insert the separator with installed tape into
the bottom cover (4). The tape's end must not contain dirt or glue residue. Insert the tape (5) into the printer,
the printer will load the tape automatically into its mechanism. Close the tape cover (2). Finally, press button

head up and take out the jammed tape. Fix the tape, lower the printing head down and try to re-load the
tape again.

Usage and storage of thermal paper

The Euro-2100TE printer prints on paper 57 mm wide.
Journal paper storage recommendations:
• do not expose thermal paper to direct light,
• air humidity max. 40 to 60 %,
• store at temperature not higher than 40°C, the best is room temperature from 18 to 25 °C,
• avoid contact of thermal paper with PVC, mollificators, organic solvents or glue.
It is necessary to use good quality paper rolls.
If usage or storage recommendations are not followed, Elcom s. r. o. does not guarantee high quality prin-
ting or preservation of printed data.
Change the paper roll immediately, if the red colour stripe marking the paper end appears at the paper
ribbon. Late change of the paper roll can cause the damage of the printer or it can shorten the printer's
lifetime.
