EEROM Model ID Configuration Procedure
The EEROM model ID configuration procedure only needs to be carried out if:
A pre8configured board is being reused.
The current board is incorrectly configured to the wrong model ID.
The Printer shows an unconfigured model ID system error (Steady EKL).
1Remove the right8end cover.
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, short8circuit 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 short8circuit the two pins.
6Once you have short8circuited 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.
8Configure the Printer with the correct model ID as follows:
Only one opportunity is given to perform this procedure and there is no indication that it was successful.
If the Printer is to be configured as a DesignJet 450C (Color) Printer, hold the Media Source key down and press the two Color Configuration (Print Quality + Media Type) keys at the same time.
If the Printer is to be configured as a DesignJet 430 (Monochrome)Printer, hold the Media Source key down and press the two Mono Configuration (Print Quality + Setup) keys at the same time.
If the Printer is to be configured as a DesignJet 455CA (LFP) Printer, hold the Media Source key down and press the two LFP Configuration (Print Quality + Reprint) keys at the same time.
9Turn the Printer OFF.
10Reconnect the media motor encoder cable to the main PCA (connector ENC X).
11Turn the Printer ON. After initializing, error code •DLM" will appear because the Accuracy Calibration must still be performed.
12Press the Cancel key and print the Demo Plot to check if the Printer has been correctly configured as a DesignJet 430, 450C or 455CA.
If the Printer is still incorrectly configured then Error Code •EKL" will be displayed on the front panel. Turn the Printer OFF and perform the EEROM Model ID configuration procedure again from step 2.
13Perform the accuracy calibration.
