Microsoft® Windows Instructions for printer firmware update

This utility is for use on Windows 2000, XP, 2003 and Vista.

The HP Color LaserJet CM1312 printers 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, for example.

Flash Firmware update process

NOTE: 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 Color LaserJet CM1312 printer, the firmware file should be for the respective model numbered devices. 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.

    1. If you choose RUN from the download security dialog window, skip step #2 and go to step #3.

    2. 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 on, 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.

    1. If there is 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 displaying “Color LaserJet CM1312 Firmware Update Utility 20080530” will open.

  6. In the window adjacent to the “select printer to update” use the drop down arrow to select the “HP Color LaserJet CM1312 PCL 6” driver. If you have previously assigned a different name to the HP Color LaserJet CM1312, choose the name that represents the correct printer.

  7. Click on the Start button in the “Color LaserJet CM1312 Firmware Update Utility 20080530” 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 Setup, Reports - press Enter, Config report – press Enter). The configuration page will display the current firmware revision in the Product information block, Firmware Datecode: 20080530.

  12. On the display of the PC, a smiling face will appear in the “HP Color LaserJet CM1312 Firmware Update 20080530” dialog box at the conclusion of the successful printer firmware update.
