Appendix A: Emergency firmware upgrade with USB flash drive

When it is not possible to perform a firmware upgrade using the normal procedures (for instance, in case of a System Error and the Embedded Web Server is unavailable), it is possible to perform an emergency firmware upgrade using a USB flash drive. Follow the next steps:

1. Copy a valid FMW firmware file onto a USB flash drive (formatted in FAT32). This file is provided in DesignJet

Online. Remove all other contents in the flash drive.

2. Turn off the printer.

3. Connect the USB flash drive to the USB port next to the Front Panel.

4. Turn on the printer and follow the instruction on the Front Panel.

Appendix B: Obtaining the printer log and the diagnostics package

The printer keeps an internal log of its own actions. When a system error occurs, the printer log can help to find the cause and the solution. By default, whenever it restarts, the printer deletes the current log and starts a new one, to avoid using a lot of hard disk space. Once the logs have been captured, the information can then be escalated to HP division for analysis.

Retrieving the diagnostic package

There are two ways of retrieving the diagnostic packages:

● From the Front Panel with a USB flash drive.

● From the Embedded Web Server.

When you have obtained the information, it should be attached to the customer case.

Retrieving the diagnostic package through the Front Panel method

This method works only if you have a standard USB flash drive. If you do not have a flash drive, use the Embedded Web Server method.

1. Take a standard USB flash drive, formatted as FAT32.

2. Create an empty file in the USB flash drive (right-click, New ►Text Document) and name it pdipu_enable.log. Then insert the USB flash drive into the printer. Once the printer recognizes the USB, a short beep will be emitted.

3. The printer starts to copy the diagnostic package to the USB flash drive. You may hear several short beeps

for each file copied to the USB flash drive.

4. Wait until the message Finished appears. You will hear one long beep, that means the entire diagnostics

package and the printer log have been copied to the USB flash drive. You can now remove the drive.

5. It will have created a folder with the name part number_serial number_time stamp, and in this folder you’ll

find one or more files with the extension trb. As the name of the folder contains the serial number, you can

reuse the flash drive for different products and the information will not be lost.

6. Disable the logs in the printer after the diagnostic package has been retrieved. See Disabling the logs in the printer through the touch control screen on page 176.

1. You can access the Embedded Web Server by typing the IP address of the printer in a Web browser. In the Support menu, click Service support to display the following page.

2. You can download the package by clicking the Download button under the Diagnostics package section of the page.

3. When you have finishing using the extended diagnostics package, remember to disable it; otherwise it could affect printer performance or even cause undesirable side-effects.

0001-04 Reset HDD to be removed

This utility resets the NVM values found in the HDD, so it can be removed from the printer. If, for troubleshooting purposes, you install a hard disk drive as a service part, and you want to remove it, run this diagnostic in order to enable the service part to be used again.
