Care and Maintenance
Some operation errors cause the error indicator to blink and printing to stop.
A message will be displayed on the front panel until the problem is fixed. If
the front panel message includes the instruction,
Call for Service , contact
an authorized service representative.
In addition, if the following conditions occur, turn off and unplug the printer
from the outlet and contact a qualified service representative:
• The power cord or plug is damaged or frayed.
• Liquid has been spilled into the printer.
• The printer has been exposed to rain or water.
• The printer does not operate normally though the operating instructions
are being followed. Adjust only those controls that are described in the
operating instructions; improper adjustment of other controls may result in
damage and will often require extensive work to restore the printer to
normal operation.
