Safety Guidelines regarding Service PC Connection

Most of the Service PCs are not in compliance with the EN60601-1
standards. Therefore a Service PC which is to be connected via RS232 or
RJ45 interface to a printer must not be connected to the mains but must be
operated on its internal battery supply (low voltage). Only in this case the
printer keeps its EN60601-1 compliance.
However, if the service PC is connected to the RS232 or RJ45 interface and
has to be connected to the mains, take care, that nobody touches the printer.

Safety Guidelines regarding the Thermal Print Head

During operation the Thermal Print
Head gets hot (up to 70 °C).
• Avoid contact with the Thermal
Print Head due to the risk of burn.
• Observe the corresponding sticker
on the Thermal Print Head.
When replacing the Thermal Head the following points must be observed:
• The thermal head has a printed circuit board integrated. This means, that
the same safety guidelines apply for the Thermal Head than for printed
circuit boards (see 1.3.2.)
• The aluminum surface, on which the Thermal Head is mounted, may not
be scratched during replacement of the Thermal Head. Possible scratches
have to be removed with a sand paper or a file, to prevent uneven
pressure of the Thermal Head on the film.
• When replacing or cleaning the Thermal Head take care not to damage
the Thermal Head: Too high pressure on the TH film guide can lead to the
failure of single heating elements. Be aware, that the Thermal Head is a
very sensitive part and has to be treated very cautiously
