Troubleshooting Printer problems The printer does not work. Action Verify that: 1. The printer is turned on and is online. 2. The printer signal cable is connected to the correct parallel, serial, or USB port on the system. For the location of the parallel, serial, and USB ports, see "Input/output connectors" on page 11. Note: Non-IBM printer cables might cause unpredictable problems. 3. You have assigned the printer port correctly in your operating system or application program. 4. You have assigned the printer port correctly using the Configuration/Setup Utility program. For information on using the Configuration/Setup Utility program, see "Using the Configuration/Setup Utility program" on page 39. If the items above are correct and the printer still does not work, run the tests described in the documentation that comes with your printer. If the tests show that the printer is OK, have the system serviced. Expansion enclosure problems The SCSI expansion enclosure used to work, but does not work now. Action Verify that all SCSI expansion enclosure hardware and cable connections are secure. Verify that: 1. The cables for all external SCSI options are connected correctly. 2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated correctly. 3. An external SCSI option is turned on. You must turn on an external SCSI option before turning on the system. For more information, see your SCSI and expansion enclosure documentation. If the SCSI expansion enclosure comes with its own test instructions, use those instructions to test it. In addition, test the power supply. If the items above are correct and the test programs found no problem, have the server and SCSI expansion enclosure serviced. Chapter 5. Solving problems 215
