HP Jetdirect LEDs The embedded HP Jetdirect print server has two LEDs. The yellow LED indicates network activity, and the green LED indicates the link status. A blinking yellow LED indicates network traffic. If the green LED is off, a link has failed. For link failures, check all the network cable connections. In addition, you can try to manually configure the link settings on the embedded print server by using the product control-panel menus. 1. Scroll to and touch Administration. 2. Touch Initial Setup. 3. Touch Networking and I/O. 4. Touch Embedded Jetdirect or EIO Jetdirect. 5. Touch Link Speed. 6. Select the appropriate link speed. 7. Touch Save. Engine diagnostics This section provides an overview of the engine diagnostics that are available in the HP Color LaserJet CM3530 MFP Series product. The product contains extensive internal diagnostics that help in troubleshooting print quality, paper path, noise, component, and timing issues. Troubleshooting menu The Troubleshooting menu allows you to run tests that can help you identify and solve problems with the product. Menu item Event Log Calibrate Scanner PQ Troubleshooting Fax T.30 Trace Fax Transmit Signal Loss Fax V.34 Description This shows the event codes and their corresponding engine cycles on the control-panel display. See Event log messages on page 468. Use this feature to compensate for offsets in the scanner imaging system (carriage head) for ADF and flatbed scans. You might need to calibrate the scanner if it is not capturing the correct sections of scanned documents. This item prints a series of eight pages that include instructions, pages for each color, a demo page, and a configuration page. These pages can help isolate print-quality problems. See Solve image-quality problems on page 494. Print or configure the fax T.30 trace report. T.30 is the standard that specifies handshaking, protocols, and error correction between fax machines. See Solve fax problems on page 507. Set loss levels to compensate for phone-line signal loss. Do not modify this setting unless requested to do so by an HP service representative because it could cause the fax to stop functioning. See Solve fax problems on page 507. Disable V.34 mode if several fax failures have occurred or if phone line conditions require it. See Solve fax problems on page 507. ENWW Tools for troubleshooting 381
