EEROM Model ID Configuration Procedure

The EEROM model ID configuration procedure only needs to be carried out if:

DA pre1configured board is being reused.

DThe current board is incorrectly configured to the wrong model ID.

DThe 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:

1Remove the right1end cover ' page 8111.

2Disconnect the media motor encoder cable from the main PCA (connector ENC X).

3Turn the Printer ON while holding the Reprint key down.

4Press the Media Source and Media Type keys together to enter the deconfiguration mode. The Fast, Normal and Best LEDs (LEDs ABC) will light up.

5Using a suitable tool, short1circuit 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 short1circuit the two pins.

6Once you have short1circuited the two pins, the Fast, Normal and Best LEDs (LEDs ABC) should light up again.

7Press the Cancel and Media Source keys together to exit the deconfiguration mode.
