Table 7-2 Troubleshooting flowchart (continued) 6 Interface Can the customer print successfully from the Verify that all I/O cables are connected correctly and that a valid host computer? IP address is listed on the Jetdirect configuration page. Yes. This is the end of No the troubleshooting process. If error messages display on the control panel, see Control-panel messages on page 440 When the customer can print from the host computer, this is the end of the troubleshooting process. Power subsystem Power-on checks The basic product functions should start up as soon as the product is plugged into an electrical outlet and the power switch is pushed to the on position. If the product does not start, use the information in this section to isolate and solve the problem. Power-on troubleshooting overview Turn on the product power. If the control-panel display remains blank, random patterns display, or asterisks remain on the control-panel display, perform power-on checks to locate the cause of the problem. During normal operation, the main cooling fan begins to spin briefly after the product power is turned on. Place your hand over the holes in the plastic cover that is connected to the rear cover and opposite of the formatter. If the fan is operating, you will feel air passing out of the product. You can also lean close to the product and hear the fan operating. When this fan is operational, the DC side of the power supply is functioning correctly. After the fan is operating, the main motor turns on (unless the top cover is open, a jam condition is sensed, or the paper-path sensors are damaged). You should be able to visually and audibly determine if the main motor is turned on. If the fan and main motor are operating correctly, the next troubleshooting step is to isolate print engine, formatter, and control-panel problems. Perform an engine test (see Engine-test button on page 583). If the formatter is damaged, it might interfere with the engine test. If the page does not print, try removing the formatter and then performing the engine test again. If the engine test is then successful, the problem is almost certainly with the formatter, the control panel, or the cable that connects them. If the control panel is blank when you turn on the product, check the following items: 1. Make sure that the product is plugged directly into an active electrical outlet (not a power strip) that delivers the correct voltage. If an error 50.05 occurs, the product is configured for a different voltage that it is connected to. 2. Make sure that the power switch is in the on position. 3. Make sure that the fan runs briefly, which indicates that the power supply is operational. 4. Make sure that the control-panel display wire harness is connected. See Control panel on page 364. 5. Make sure that the formatter is seated and operating correctly. 6. Remove any HP Jetdirect or other EIO cards, and then try to turn the product on again. ENWW Troubleshooting process 427
