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 ' page 8Ć11.
2 Disconnect the media motor encoder cable from the main PCA (connector
ENC X).
3 Turn the Printer ON while holding the Reprint key down.
4 Press the Media Source and Media Type keys together to enter the
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 Cancel and Media Source keys together to exit the
deconfiguration mode.
