Flash Download Commands

These commands are used to load firmware into the printer.

The commands are listed in numerical order according to their hexadecimal codes. Each command is described and the hexadecimal, decimal, and ASCII codes are listed.

There are three ways to enter the Download Mode:

•Powering the printer up with DIP Switch 2 up.

•While the printer is running normally. Use the command Switch to Flash Download Mode to leave normal operation and enter the Download Mode.

•If the Flash is found corrupted during Level 0 diagnostics, the Download Mode is automatically entered after the printer has reset.

The printer never goes directly from the Download Mode to normal printer operation. To return to normal printer operation, either the operator must turn the power off and then on to reboot, or the application must send a command to cancel Download Mode and reboot.
