PRINTER HOT
PRINTER UNDER
REMOTE CONTROL
PROTECTED INSTR*
Explanation
This message indicates
internal temperatures over
60° Celsius (140°
Fahrenheit). Print jobs will
not create such
temperatures, so
immediately determine that
the fans are operating and
that all air vents are
unobstructed. It is crucial
that the exhaust vents on the
floor of the cabinet remain
unblocked, since hot air from
inside the printer is vented
through the cabinet floor.
Nothing must be stored
under the printer. Then
check the operating
environment. A severe
environment is one with an
ambient temperature at or
above 40° Celsius (104°
Fahrenheit) or is dirty
enough to create blockage
of the cabinet fan vents. The
printer must never be run at
ambient temperatures
greater than 40° Celsius
(104° Fahrenheit). If the
printer is located in such an
environment, relocate it to a
cooler, cleaner area.
Status message: The printer
is under the control of the
PrintNet Enterprise (PNE)
remote printer management
software.
Protected Instruction.
Firmware error on the
controller board.
