EEROM Model ID Configuration Procedure
The EEROM model ID configuration procedure only needs to be carried out if:
D
A preĆconfigured board is being reused.
D
The current board is incorrectly configured to the wrong model ID.
D
The Printer shows an unconfigured model ID system error (
Steady EKL
).
It is very rare that these situations will ever occur.
Configure the Printer model ID as follows:
1
Remove the rightĆend cover
'

deconfiguration mode
. The Fast, Normal and Best LEDs (
LEDs ABC
)
will light up.
5
Using a suitable tool, shortĆcircuit pins 1 and 2 (the first two pins on the
right) of the media motor encoder connector (ENC X). The Cartridges,
Data and Media LEDs (
LEDs KLM
) should light up as you shortĆcircuit
the two pins.
6
Once you have shortĆcircuited the two pins, the Fast, Normal and Best
LEDs (
LEDs ABC
) should light up again.
7
Press the
