After reviewing each procedure, place a check in the box.
The AC power plug and IEC 320 connectors on all Zebra printers must bear the
certification mark of at least one international safety organizations listed below.
Unless indicated otherwise, turn the printer Off (O) before performing any
maintenance procedures to the printer.
Zebra printers comply with international regulations governing radiated emissions
when using fully shielded data cables. Data cables must be fully shielded and
fitted with metal or metallized connector shells. Required shielded data cables and
connectors prevent radiation and reception of electrical noise. Use of non-shielded
data cables may increase radiated emissions above the regulated limits.
Permanent damage to the flash memory will result if you power up the printer
with flash memory chips installed in the wrong direction.
To ensure optimum printhead life, observe proper electrostatic safety precautions
(i.e., ESD Wrist Straps) when removing, handling and replacing the printhead.
