Advise the user to move the printer to cooler, cleaner location.
2. Power off the printer. Remove the paper guide assembly or pedestal top cover.
Check that all fan cables are connected.

(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 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 or reduce the size and duration of the print jobs.
