No power, and the operator panel is blank, and the card cage fan is not running
1. Check that the AC power outlet has power. Restore AC power as required.
2. Unplug the printer AC power cord from the printer (leave it plugged into the power outlet) and check for AC power at the printer end of the cord. If there is no power through the AC power cord, replace it. Plug the AC power cord into the printer and power outlet.
3. Remove the paper guide assembly or pedestal top cover. Verify that the AC-in power cable and the AC power input cables are connected to the on/off switch/circuit breaker. Connect the AC-in power supply cable and AC power input cables to the on/off switch-circuit breaker. Make sure all ground connections are clean and tight.
4. Check that AC-in power cable connector P1 is connected to J1 on the power supply board.
5. Check that power supply cable connector P101 is connected to J101 on the controller board.
6. Check all cable connections on the controller board. Reseat all cables, making sure that none of the cables are connected upside down.
7. If the printer has the coax/twinax expansion board, make sure the 60-pin expansion adapter is correctly seated in the controller board and the coax/twinax expansion board.
8. Disconnect AC-in power supply cable connector P1. Set the circuit breaker to 1 (on). Measure AC voltage at pins 1 and 2 of connector P1. If there is no voltage, replace the circuit breaker. If there is voltage, replace the power supply board.
Printer loops IML 1. If the printer is using the coax/twinax interface, check that the coax/twinax card is correclty installed.
If it is installed, reseat the card and all connectors and try again. If the problem still occurs, replace the coax/twinax interface and reload code.
2. If the printer is using the Ethernet NIC, download the latest code from IBM First (page 247) and reload the code (page 249).
3. Go to “Printer does not complete IML” (page 191).
88 - 270 V DANGER
Printer does not complete IML NOTE: Power-on initialization is explained on page 241.
1. Verify that the customer’s power supply is within the specification of the printer.
2. Power off and unplug the printer. Remove the paper guide or pedestal top cover. Check that all cables are connected to the controller board. Reseat all cable connectors on the controller board, especially connectors P106 and P107. Also reseat flash and DRAM SIMMs.
3. If the printer has the coax/twinax expansion board, verify that the correct microcode is loaded in the machine. Download CT emulation software. If the printer does not have the coax/twinax expansion board, go to step 8.
4. Power off and unplug the printer. Check that the user has enough flash memory installed to handle his emulation software. If necessary, install flash memory and DRAM and download the latest code from IBM First (page 247). Power on the printer in download mode and load flash memory (page 249).
5. If the problem persists, replace the flash memory and DRAM. Following replacement, power up the printer in download mode and load flash memory (page 249).
6. Power off and unplug the printer. Check the coax/twinax adapter connection to the controller board.
Make sure that J111 is correctly seated between the controller board and the coax/twinax expansion board.
7. Plug in the printer and power it on. If the printer does not successfully complete IML, replace the coax/twinax expansion board.
8. Plug in the printer and power it on. If the printer does not successfully complete IML, replace the power supply board.
9. Plug in the printer and power it on. If the printer does not successfully complete IML, , the controller board or microcode is suspect. Do the following:
10. Save the printer configuration values. (Refer to the Setup Guide.) 11. Clear NVRAM (page 248).
12. Download and install the latest code from IBM First (page 247).
13. Power on the printer in download mode and load flash memory (page 249).
a. If you encounter loading problems, go to the appropriate error code for resolution..
Printer does not complete IML (continued)
b. If you encounter the failure or message that brought you to this procedure, replace the controller board (page 365). After replacing the controller board, DO NOT make the printer READY, but proceed immediately to the next step
14. Download and install the latest code from IBM First (page 247).
15. Power on the printer in download mode and load flash memory (page 249).
16. If you encounter the failure after replacing the controller board, power off and unplug the printer, reinstall the original controller board, and replace the shuttle frame assembly.
17. Plug in the printer and power it on. If the problem persists, replace the operator panel and cable.
18. Plug in the printer and power it on. If the problem persists, contact your DDS and Second Level Support.
Printer Power On Resets (POR) by itself
1. Download the latest code from IBM First (page 247). Power on the printer in download mode and load flash memory (page 249).
2. Power off and unplug the printer. Verify that the customer’s power supply is within the specification of the printer.
3. Reseat the flash and DRAM SIMMs.
4. Plug in the printer and power it on. If the problem persists, replace the power supply.
5. Plug in the printer and power it on. If the problem persists, the controller board or microcode is suspect. Do the following:
