OF 16
Status Indicator RAPs
OF 16 POST Error RAP
Power on Self Test (POST) occurs each time the machine is powered on. POST verifies the
functionality of key subsystems before passing control to Print Engine Self Test (PEST).
• Use this RAP when the UI has stalled and shows the splash-logo screen, or the system
appears to have power but the UI is blank.
• POST begins when power is switched on before higher level machine functions (such as
the user interface) are operational.
• POST is performed by the IME controller PWB and the single board controller PWB.
• The IME POST results are displayed using the LED’s on the front of the IME controller
PWB, Figure 1, and two LED’s at the rear on the media path driver PWB, Figure 2.
LED’s on the front of the IME controller PWB, Figure 1.
– ENG OK (green, DS302) - Displays IME firmware status.
– ENG error (red, DS301) - Displays IME firmware error blink codes, the first digit is 3
or 4.
– Cable error (red, DS604) - Displays status of major cables in the IME and -12V
needed for the printhead PWBs.
– CPU error (red, DS605) - Displays IME operating system status and error blink
codes, the first digit is 2.
• The 2 media path driver PWB LED’s on the back of the machine display the same pat-
terns codes as the 2 engine status LED’s on the front IME. If there is a loss of communi-
cation with the media path drive PWB, at PJ 408, only the front LED’s will blink.
LED’s on the Media path driver PWB, Figure 2.
– IME OK (green, DS801) - Displays IME firmware status.
– IME error (red, DS802) - Displays IME firmware error blink codes.
• The 7-Segment LED display unit on the rear of the machine attached to the SBC PWB,
Figure 3. This is to help diagnose common faults which prevent the machine from power
-
ing up correctly to the point where faults are displayed and diagnostics can be entered.
The LED display should show just a pulsing decimal point when the machine boots cor
-
rectly, The main codes are displayed for short periods of time during power up depending
on how long each test takes, if any code is left displayed during power up and the
machine appears not to have powered on correctly then this should point to the problem
component. Refer to the Table 3.
