PRINTER HOT
NOTE: 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 should be stored
under the printer. Then check the operating environment. A severe
environment is one with an ambient temperature consistently above
40° Celsius (104° Fahrenheit) or is dirty enough to create blockage
of the cabinet fan vents. If the printer is located in such an
environment, consider relocating it to a cooler, cleaner area or
reducing the size and duration of the print jobs.
