Chapter 1 Troubleshooting Display Messages Operator Panel Message 060 PRINTER HOT SEE USERS MANUAL Table 3. Message List Explanation Corrective Action Controller board sensors report high temperatures on the board. This message indicates internal temperatures over 60° Celsius (140° Fahrenheit). Print jobs do 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. 1. Inspect printer environment for severity. Advise the user to move the printer to cooler, cleaner location. 2. Power off and unplug the printer. Remove the paper guide assembly or pedestal top cover. Check that all fan cables are connected. 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. 4. Remove the shuttle cover and Check the shuttle for electrical shorts (page 252). 5. Install the paper guide assembly or pedestal top cover. Plug in the printer and power it on. Load paper. Run the Plot Test for 1/4 page. If the problem reappears, the controller board or microcode is suspect. Do the following: 6. Save the printer configuration values. (Refer to the User's Manual.) 7. Clear NVRAM (page 237). 8. Download and install the latest code from IBM First (page 231). 9. Power on the printer in download mode and load flash memory (page 238). a. If you encounter loading problems, go to the appropriate error code for resolution. b. If you encounter the failure or message that brought you to this procedure, replace the controller board (page 319). After replacing the controller board, DO NOT make the printer READY, but proceed immediately to the next step. 10. Download and install the latest code from IBM First (page 231). 11. Power on the printer in download mode and load flash memory (page 238). 66
