I have tried doing an LED Diagnostics, but even when the probe is attached, the portable device says that the probe isn't attached.
The following lists the chain of events that occur when you turn on a printer. You can follow this list as one means of determining if the printer is operating correctly. The exact chain of events depends upon the last power down condition and where the printer has last determined the printhead is positioned, this is stored in non-volatile RAM. The Checklist is the primary reference for troubleshooting power-up problems.
1. Power cord is plugged in and the power switch is turned on:
2. Power supply senses AC line voltage conditions (110 VAC or 220 VAC)
and enables DC voltages. If an overload occurs, the printer turns off the high voltage DC supplies, causing a "blink" effect on the Control Panel LEDs.
3. BIST test flashes the PE LED very briefly at a fast rate until the end of the
next test.
4. The Boot loader performs CPU initialization and RAM test. It then sends
the boot loader version to the serial port.
5. Power-On Self Test (POST) initializes the Control Panel. The Control
Panel LED turns red, green, orange, and then off. The Control Panel LCD then goes black and then clear. The POST version displays on the LCD
and waits two seconds. During this time the operator can press the Back
button to bypass the remaining POST test.
6. Low level Power-On Self Test (POST) diagnostics are performed. The
Control Panel displays status messages as each sub-test is performed.
This test takes about 8 seconds. All LEDs are off during the test.
If POST diagnostics pass, the Control Panel displays the Xerox logo and turns on the green LED.
If the test detects an error, the error message displays on the LCD and the printer flashes the LEDs with a repeating error code pattern.
7. The VxWorks operating system is initialized and engine code is started.
This takes about 15 seconds. The Xerox logo is displayed.
8. Print Engine Self Test (PEST) diagnostics are then performed. These test
the heaters, clutches, motors and solenoids. As each clutch is tested, you hear clicking with four high tones as each motor is tested. This test takes about 30 seconds.
9. The printer now runs the mechanical initialization. The exact sequence
depends on the initial position of the printhead and wiper assembly.

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It
lights up and will stay orange when the Router is powered on. The color orange indicates that
the Router is not using the SecureEasySetup feature, while the color white indicates that the
Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup
mode, the Cisco logo will turn white and start flashing. After the Router has generated
the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.
To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.
The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to
indicate a successful reset.NOTE: SecureEasySetup is a feature that makes
it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's
Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.
Power (Green) The Power LED lights up and will stay on while the Router is powered
on. When the Router goes through its selfdiagnostic mode during every boot-up, this
LED will flash. When the diagnostic is complete, the LED will be solidly lit.
DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will
remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when
the wireless feature is enabled. If the LED is flashing, the Router is actively sending or
receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.
Internet (Green) The Internet LED lights up when there is a connection made through the
Internet port. A flashing LED indicates network activity over the Internet port.
Good luck
