7.5.6 Displaying Details of Service Call Error Codes (C3200/C3100/C5510)
With the C3200/C3100, whenever service error occurs, each LED-Paper, Consumable, and
Alarm-rapidly blinks simultaneously at 120mS intervals. Every time the ONLINE SW and the
CANCEL switch are depressed simultaneously for 5 seconds or more in this state, the printer
enters error code display mode. In this mode, each error code, a three-digit decimal number,
represents 12 bits (4 LEDs x 3 times).
After the error code display mode starts, LED displays the hundred's place of the error code. If the
ONLINE SW is depressed once in this state, LED displays the ten's place of the error code. If the
ONLINE SW is depressed twice in this state, LED displays the one's place of the error code.
Immediately after the ONLINE switch is depressed (200mS), all the LEDs go off so that a user can
confirm that the switch was depressed even though the same code such as 111 or 222 continues.
If the ONLINE SW is depressed three times, error code display mode ends, and the LED will go
back to its rapid blinking state. If it is not depressed for more than 20 seconds, error code display
mode ends as well.
One example of LED display pattern at error occurrence is provided below. The LED is laid out in
the order of Ready, Paper, Consumable, and Alarm from the far left side, and what each symbol
means is given in Table 7-5-6-3.
Value conversion method:
Regard 4 LEDs as bit0, bit1, bit2, bit3 from the right. 4 bit value when Off LED is 1, On LED
is 0.
