Warning: Before performing a firmware update on the printer, contact the technical service center or second
level of support to verify the correct firmware and keycode. The wrong firmware or wrong level of
firmware could lead to a malfunction or render the printer inoperable.
There are three options to update firmware on your printer. The instructions for all
three options are listed below.
Using the host computer to update the firmware over USB
This procedure uses the program USBFlash. USBFlash is a utility that can also be used to update firmware from
a host computer via USB. To use the USBFlash utility, the printer must be installed on the host computer so a
USB virtual printer port can be established on the host computer. The virtual printer port is needed so the host
computer can communicate with the printer.
Note: Make sure the printer is attached over USB and “Ready” or “Invalid Engine Code” posts on the operator
panel. If the printer cannot go to the “Ready” state or is not in the “Invalid Engine Code” state, power the unit off.
Power the unit back on while holding down Back ( ) and Left . on the operator panel until “*128MB” posts
on the operator panel. Once the printer powers up, “Invalid Engine Code” should be posted on the operator
panel. The firmware can now be updated.
To update the firmware, perform the following steps:
1. Download the USBFlash utility and firmware files to the host PC (these files can be found by going to
http://www.olinet.biz).
2. Unzip the ZIP file to a new folder on the host computer.
3. Open the new folder containing the files that were just unzipped.
4. Confirm the printer is in Ready or Invalid Engine Code mode. If it is not in either mode, refer to the note
above.
