Notes
• Always operate the key to obtain a paper feed. Never pull the paper with
your hands as this could damage the printer.
• Thermal paper has a limited shelf life: Protect it from light! Do not store it in plastic
folders (plasticizers make the printing illegible)!
• Never operate the printer without paper!
• Use only original 6.2237.020 thermal paper! The printer head could otherwise be dam-
aged.
• If the printer no longer prints out correctly it is possible that the printer head is dirty. It
can be cleaned by inserting a sufficiently long strip of printer paper the wrong way
round in the printer and "printing" a few reports on it.
