EEROM Model ID Configuration Procedure for the DesignJet 330
and 350C
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 plotter shows an unconfigured model ID system error (Steady 135).
It is very rare that these situations will ever occur.
Configure the plotter model ID as follows:
1 Remove the left cover ' page 6Ć10.
2 Disconnect the media motor encoder cable from the main PCA (connector ENC X).
3 Turn the plotter ON in Service Mode 1.
4 Hold the ALT key down and press the Deconfiguration Mode key.
5 Once in Deconfiguration Mode, the first and second LED
columns should light up.
6 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 second and third LED columns should light up as you
shortĆciruit the two pins.
7 Once you have shortĆcircuited the two pins, the first and
second LED columns should light up again.
8 Press the
Shift
key to exit the Deconfiguration Mode.
