3.3 Parts removal and replacement
WARNING!
RISK OF INJURY! Depending on the position of the crank mechanism in the cutting
module, the cutting knife may start moving when the printer is switched ON.
KEEP HANDS AWAY!
CAUTION!
The printer power supply should be switched off, and the low-voltage power cable should
be disconnected from the control board before you disconnect or connect any other cable
on the control board. The printer electronics might otherwise be damaged.
CAUTION!
The printhead and some components on the control board are sensitive to ESD
(electrostatic discharges). To prevent damaging such components, observe all the usual
precautions such as keeping the part in its original packing (“ESD-bag”) until you are
ready to install the part. Do not touch its pins. Use a grounded wrist strap when handling
ESD-sensitive components.
CAUTION!
If the printer or print module is not to be used for a week or so, disengage the printhead
from the platen by lowering the paper release lever. Otherwise, both the printhead and the
platen can be deformed.
