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 section contains an initial troubleshooting checklist that
helps to eliminate many possible causes of the problem. The remainder of the chapter provides
steps for correcting the problems that have been identified.
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 
.
2
Check the network connection. See 
.
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.
