3390_FW_Update-200703314.exe (4.0 MB)

NOTE: The LaserJet 3050/3052/3055/3390/3392 share firmware code, so the enhancements/fixes are the
same for all products. There are, however, separate upgrade utilities for the LJ3050, LJ3052/55 and
LJ3390/92. The file names are listed above in the File Names section.

Fixes/Enhancements

These changes are implemented in firmware date code 20070331 (Rev G).

Improved scanning over Microsoft Windows Vista network connections.

This revision includes fixes from previous rolls:

Removal of HP logo from internal pages. (HP logo in the demo page remains).
Print performance improvement for PCL5e.
Fix for illegal font data for ITC Zapf DingBats for PCLXL when Wizard PCL6 driver is used.
Corrected Stretched Horizontal Pixel issue.
Corrected Scan-through-USB issue for Windows Vista.
Improved IP address management of DHCP to Manual changes.
Corrected issue where factory default hostname was overridden by Custom Hostname.
Improvement for Historical Coverage reporting.
Improved Supplies Status Reporting.
Image quality adjustment.
Adjusted AEC EWS Security fix from previous roll.
Corrects issue where every fifth copy page is corrupted when device is set to Photo copy mode.
Corrects issue where the FW Upgrade Utility won't work if a DIMM is installed (LJ3390/92 only).
Previously, the FW upgrade utility only worked if the LJ3390/92 DIMM was removed.
Removed a paper prompt message from this scenario: A print job with Paper Type set to Unspecified is
sent to a specific tray, but that tray has been configured with type other than Any.
Updated the basic Firmware code to enable version-checking feature to be added.
Added version-checking to the Firmware Update Utility to prevent firmware code for one device from
being downloaded to another product. Previously, if incorrect firmware was downloaded and code
update completed, the formatter was corrupted and required a formatter replacement. Now, if an
incorrect version of firmware is downloaded to a device, the device will post the message "Fatal Error
9" on the control panel and prevent the incorrect code from being installed. The device will recover
from this error state, retaining the firmware it had installed just prior to the attempted update. Clear the
message by turning the device power off and back on. The user should retrieve the correct Firmware
Update Utility from HP.com and proceed with updating the device with the correct code for the
product.
Enhanced EWS Security by extending the EWS solution password/security access control from only
the Networking Tab, to include the Fax, System, and Print Tabs.
The 49 error when connecting a USB cable after printing the service page has been corrected.
Improved Scanning performance.
Removed Auto Cleaning Page prompt when installing a new toner cartridge. The feature is still
available in the Service Menu at the Control Panel.

01/08/2019 https://support.hp.com/soar-attachment/800/col13629-col13629-31rm.html

Fixed the paper handling issue where the device pauses when paper tray 3 is empty.
Improved network configuration reporting.
Corrected a network issue where network status is incorrect when network cable is unplugged when the
device is powered on. If the device is powered up with the network cable disconnected, the
Configuration and Network Configuration page would display 'Initializing.' The corrected "Network
Cable Disconnected" status message is now displayed.
All Fax Settings are now saved/restored with the Save/Restore function.
Improved fax printing speed.
Fixed 49 Service Error due to fax header length incompatibility (fax header is limited to 25 characters
in software and firmware).

MS Windows Instructions for printer firmware update:

This utility is for use on Windows 98SE, ME, 2000 Vista and XP. The HP LaserJet 3xxx printer must be in a
READY state as shown by the LCD display on the control panel and remain powered on during the entire
firmware update process.

Depending on the speed of your PC, the firmware update process may complete on the printer, before
the progress bar on the screen completes.
Once the firmware update process has started, Do Not power cycle the printer or the PC until the
firmware update process is complete. Avoid using the device during the firmware upgrade procedure-
don't send a print job, or attempt to send a fax for example.

Flash Firmware update process

IMPORTANT - Before the process starts: Turn the printer off and then back on at this time only to clear
main printer memory.

Make sure the firmware being updated is for the correct LaserJet product. For example, if you are updating
the LJ3380, the firmware file should be for the LJ3380. If the incorrect version of firmware is downloaded to
a device, the error "Fatal Error 9" will appear on the control panel (preventing the incorrect code from being
installed). This error can be removed by rebooting the device. The device will retain the version of FW it had.
The user should retrieve the correct version of firmware from HP.com and use the Firmware Upgrade Utility
to update the device with that code.

1. Download the file to the desktop, if the "Save" from the download security dialog window is chosen.
If you choose "RUN" from the download security dialog window, skip step #2 and go to step 3.
Click on "Run" if a Microsoft internet explorer security window pops up.
2. Double click on the flash firmware update utility file. Click on "Run" if a Microsoft internet explorer
security window pops up.
3. Read and Evaluate the license and click on "accept terms" if you wish to continue with the update.
4. If there is only one printer to update the firmware in, accept the default (the radio button already
selected) unpack location. Click on "Next." This default installation selection, will delete the
downloaded files at the end of the firmware update process.
If there are more than one printer to be updated, choose the "unpack to a specific location" by
selecting the lower radio button and then click next. Take note of the default directory for later
use when updating other printers.
5. A Window "LaserJet 3xxx Firmware Update Utility 20070331" will open.
6. In the window adjacent to the "select printer to update" use the drop down arrow to select the "HP
LaserJet 3xxx PCL 6" driver. If you have previously assigned a different name to the HP LaserJet 3xxx
choose the name that represents the correct printer. DO NOT select the "HP LaserJet 3xxx Fax" printer
for this update.
7. Click on the "Start" button in the "LaserJet 3xxx Firmware Update Utility 20070331" dialog window.
8. The progress bar will begin to move to the right indicating information being transferred
9. DO NOT power cycle the printer or the PC during this process or the printer may become unstable and
or unusable without further attention from HP. The firmware update can take up to 5 minutes to
complete. Please be patient.
10. During the printer firmware update, the liquid crystal display (LCD) on the printer control panel will
display "Printing Document" and will change to "Erasing". After a short while, the LCD display will

change to "Programming" After a short while, the LCD will display "complete : )" The "Ready" LED
on the printer will start flashing. The printer will automatically power cycle to reboot and will make
noises similar to power on.
11. To verify the update, a configuration page can be printed from the printer control panel (Select menu, >
reports - press enter, > config report - press enter). The configuration page will display the current
firmware revision in the Product information block, Firmware Datecode: 20070331.

20070331" dialog box at the conclusion of the successful printer firmware update.
