In order to update the firmware or engine code on any Lexmark laser printer through the USB port on a MAC OS 10.x, you need to install the
TOOLS.DMG package. This package includes the Printer File Loader, a small application that will send the firmware file directly to the printer. Follow the instructions below.
- Start by installing tools.dmg on your computer. To do this:
- Go to ftp://ftp.lexmark.com/driver/macintosh_printers/ and download the tools.dmg file to your desktop.
- Double-click on the file. A window containing the tools installer package, tools.pkg, will appear.
- Double-click on the file. The Introduction screen will appear.
- Click Continue. The Installation Read Me screen will appear.
- Click Continue. The License Agreement appears.
- Read the License Agreement and click Continue.
If you agree to the license, click AGREE. If not, click DISAGREE. NOTE: If you select DISAGREE, the installation will abort.
- Select a destination volume for the Tools software. (This is usually the operating system's hard drive.) Click Continue.
- Click Upgrade to install the software package.
- Once the screen says Successfully Installed, click Close.
- You can now download the required firmware or engine code file to the Macintosh.
- To send the file through the Printer File Loader:
- Open the MAC HardDrive.
- Double-click on Applications.

- Click on the USB heading and then search for your printer in the list.

.
- Once your file has been selected, click Send
.
IMPORTANT: When sending the file, make sure the printer is at either a READY or an Invalid Engine Code state. If it is posting another message, this will probably interfere with the communication between the printer and the MAC. It is also recommended that the cable be plugged directly into the back of the MAC, not through a keyboard, USB multiport hub, or any other third-party device.
If you are having difficulties sending the firmware or engine code to the printer, please contact the Lexmark Technical Support Center at 800-LEXMARK for additional support.
