Table 28. Control panel and event log messages-3,000-sheet stapler/stacker (continued) Event log, if connected to Control panel message 9000 9500, 9500mfp, 9050, 9000mfp 9050/9040mfp User LED Service LED Description 66.12.50 Output device failure 66.12.50 66.12.50 66.12.50 Amber solid Red (6 blinks) The stack holder system is damaged Recommended action: NOTE: The device is operable under this condition. However, the user might experience a high incidence of accumulator-eject jams and poor stacking. 1 Analyze the event log for frequency of the error message. 2 Turn the printer or MFP off and then on again to see whether the error is present during the power-on sequence. NOTE: The stack-holder contains no FRUs. If the error message appears in a solid condition, then the whole unit might have to be replaced. Follow your regional escalation process to replace the unit. 66.12.60 Output device failure 66.12.60 66.12.60 66.12.60 Amber solid Red (7 blinks) An EEPROM error exists. One or more cells in the internal EEPROM on the controller PCA is damaged. Recommended action: NOTE: The device is operable under this condition. However, functionality depends on the area of memory that is damaged. 1 Analyze the event log for the frequency of the error message. 2 Turn the printer or MFP off and then on again to see whether the error is present during the power-on sequence. 3 Check the Jet Link cable connections. 4 If the message persists, then replace the controller PCA. External device None initializing None None Amber blinking Red solid The device is performing its power-on sequence along with the printer or MFP. Recommended action: This message should appear for a few minutes. If the message persists, then check the following issues: 1 Make sure that the power cord is connected. 2 Check connections at the controller PCA. 3 Replace the Jet-Link cable as needed. 4 Replace the controller PCA as needed. Optional bin 1 None full None None Amber blinking Green solid The face-up bin is full. More than 125 sheets of 75-g/m2 (20-lb) paper have accumulated (or fewer than 125 sheets, if heavier media is in use). Recommended action: 1 Remove all media from the face-up bin. 2 If the message persists when the bin is empty, then make sure that the FLFUF actuator (see page 83) moves freely. 3 Check the functionality of the FLFUF sensor by using the sensor test (see "Face-up bin-full sensor test" on page 240). 4 If the FLFUF actuator moves freely and the FLFUF sensor operates correctly, but the message persists, then replace the flipper assembly. 216 Troubleshooting ENWW
