1.3.1 General safety guidelines for service work
The following points must be observed during all repair or maintenance work:
Make sure to always disconnect the machine to be repaired or maintained
from the mains.
•
Caution: Even when the machine is switched off, as long as it has not
been disconnected from the mains some components may still be
supplied.
•
Caution: If the mains connection is absolutely necessary for the
respective action (repair and maintenance work), this job must only be
done by trained personnel.
•
Before printer service or replacing conductive parts always switch off the
printer and disconnect the power.
•
Before switching the printer off make sure that there are no films being
printed at this time.
•
Replace defective parts with original spare parts only.
1.3.2 Safety Guidelines for Printed Circuit Board Replacements
When handling printed circuit boards (abbr.: PCBs) the following points must
be observed:
•
Always switch off the printer and unplug the power cord, before you
disconnect or connect cables on printed circuit boards.
•
When working on PCBs, always wear an anti-static wrist strap. Never
touch any parts or components on PCBs with your bare fingers.
•
PCBs have to be kept or transported in their protection bags. Never carry
a PCB without protection bag and walk on carpet or plastic floor covering
(electrostatic charge).
•
Once the PCB is taken out of its protection bag, it has to be protected
from electrostatic charge by a grounded mat.
