No action required. 060 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 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. 1. CMX controller board sensors report high temperatures on the board. Inspect printer environment for severity. (See NOTE above.) 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. Connect all fan cables. 3. Inspect vents and fan airways for obstructions. Look underneath cabinet models for items blocking the cabinet exhaust vents. Remove any obstructions from vents and airways. Troubleshooting 85
