The purpose of this Service Utility is to modify identification parameters such as serial and model numbers, as well as the Font Type. This only needs to be performed when EEROM failures cannot be recovered where both the current EEROM (located in the Main PCA) and the backup EEROM (located in the Ink Supply Station) contain false values or because both of them have failed.

Also, you can use this utility to reset the usage counters for parts that have been replaced in order to correctly reflect the true usage of the relevant parts.

WARNING: After any change in the EEROM, switch the Printer OFF and ON again in order to ensure that the change takes effect in all the subsystems of the Printer.

Perform the EEROM Setup as follows:

1. In the Service Utilities submenu, scroll to "EEROM Setup" and press Enter.

2. The Printer will display a list of EEROM Setup options. You can make your selection using the arrow keys and press Enter to view the selection.

If you want to select the Serial Number

If you want to select the Serial number, then you should select "Serial number" and press Enter. The following information will be displayed on the front panel. You will need to use the arrow keys to scroll through the complete list because the front panel only allows 6 lines to be displayed at one time.

Use the arrow keys to scroll through the list of digits. Once the digit that you require is highlighted, press Enter to select it and it will appear in the New line.

Once you have entered the last digit of the new serial number, the front panel will display the following message:

If you press Enter, the new serial number will be stored in the EEROM and the Printer will return to the EEROM setup options menu. If you press Back, the previous screen will be displayed and the last digit of the new serial number will be deleted. You now have the opportunity to modify the new serial number.

If you want to change the Font Type

If you want to change the Font Type to Japanese, then you should select "Font type" and press Enter. The following message will be displayed on the front panel asking you to confirm whether you want to change the font to Japanese. Select YES and press Enter if you want to change to Japanese. Select NO and press Enter if you don't want to change the font type to Japanese.

NOTE: If the Printer is not a DesignJet 800PS, or if the Printer does not detect a formatter, the Printer will not allow you to enter this utility and will display the following message on the front panel.

If you want to Reset the Usage Counter

NOTE: You should only reset the usage counter for a certain component when it has been replaced by a new one. Never reset the usage counter for a component when it has not been replaced.

If you want to reset some of the parameters of the usage counter (to consult the usage counters » Printer Information), then you should select "Reset usage counter" and press ENTER. The following information will be displayed on the front panel. You will need to use the arrow keys to scroll through the complete list because the front panel only allows 6 lines to be displayed at one time. Select the usage counter that you want to reset and then press Enter.

Once you make a selection (for example Scan axis usage), the following message will appear on the Front Panel. Press Enter if you want to proceed with resetting the counter or press Cancel if you want to exit without resetting the counter:

To check if the relevant usage counter has been reset, enter the Printer Information utility » Printer Information.

If you want to Reset the EEROM to the Default Values

NOTE: The EEROM should only be reset if there is a major problem or if the Electronics Module has been replaced by a reused one and you need to reset the EEROM configuration. Also reset the EEROM if the Printer does not have the correct Serial Number after powering up.

If you want to reset the EEROM to the default values, then you should select "Reset to defaults" and press Enter. The following message will appear on the Front Panel. Press Enter if you want to proceed with resetting the EEROM or press Cancel if you want to exit without resetting the EEROM:

NOTE: After resetting the EEROM to the default values, you will need to re-enter the Serial Number, Model Number and the Font Type (without re-entering this information, the Printer will NOT work). DO NOT SWITCH THE PRINTER OFF AND ON AGAIN BEFORE RE-ENTERING THESE VALUES. Also you will need to perform the Factory Advance Calibration.
