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.

NOTE: NOTE: If the formatter is not seated correctly or if it is not functioning correctly, the device will not power up and no power will be available to the fans. This condition sometimes can be mistaken for a power-supply issue when 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 hear the main motor if it is 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. See External control-panel cable on page 63.

5.Remove any HP Jetdirect or other EIO cards, and then try to turn the digital sender on again.

6.Verify that the formatter “heartbeat” LED is blinking. See LEDs on page 126. The heartbeat LED indicates that the formatter is fully functional. If the heartbeat LED is not blinking, reseat 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.

NOTE: 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.
