HP Digital Sender 9200c - Understanding the Troubleshooting Process

When the digital sender malfunctions or encounters an unexpected situation, information on the control panel alerts you to the situation. This document contains an initial troubleshooting checklist that helps to eliminate many possible causes of the problem.
  • Use the initial troubleshooting checklist to evaluate the source of the problem and to reduce the number of steps that are required to fix the problem.
  • Use the troubleshooting information in this chapter to pinpoint the cause of malfunctions.

Initial troubleshooting checklist

If the digital sender is not responding correctly, complete the steps in the following checklist. If the device does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolves the problem, you can stop without performing the other steps on the checklist.

Troubleshooting checklist

  1. Make sure that the digital sender Ready LED is on. If no lights are on, see Power-on checks.
  2. Check the network connection.

Power-on checks

The basic digital-sender functions should start up as soon as the digital sender is plugged into an electrical outlet in a wall receptacle and the power switch is pushed to the on position. If the digital sender does not start, use the information in this section to isolate and solve the problem.

Power-on troubleshooting overview

Turn on the digital sender. If the control-panel display remains blank, random patterns appear, or asterisks remain on the 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 digital sender power is turned on. Place your hand over the holes in the rear cover, above the formatter. If the fan is operating, you will feel a slight vibration and feel air passing into the digital sender. You can also lean close to the digital sender 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 the remaining problems.
If the control panel is blank when you turn on the digital sender, check the following items.
  1. Make sure that the digital sender is plugged into an active electrical outlet that delivers the correct voltage.
  2. Make sure that the on/off 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.
  5. Make sure that the firmware flash memory card and the formatter are seated and operating correctly. Verify that the compact flash card is in slot 1.
  6. Remove any HP Jetdirect or other EIO cards, and then try to turn the digital sender on again.
  7. Verify that the formatter “heartbeat” LED is blinking. The heartbeat LED indicates that the formatter is fully functional. If the heartbeat LED is not blinking, reseat the compact flash card and the formatter assembly.
If the scanner base fan is not operating, verify that all connectors to the power supply and the scanner base fan are correctly seated. If the fan is still not functional, replace the components one by one until the system is functional.
It is important to have the control panel functional as soon as possible in the troubleshooting process so that the control-panel display can be used to help locate digital-sender errors.
