Applicable To

Resolution / Answer

To maintain continuity in Zebra’s manufacturing process and to address global constraints on flash memory availability, a new set of memory components may be used as new printers are manufactured. These new memory components are future compatible with Link-OS v5.1 and later printer Operating System releases but will not be backward-compatible with earlier Link-OS versions.

To ensure compatibility between the flash memory and printers operating systems, Industrial and Desktop printers that are already running v5.1 or later will not support downgrading to printer OS versions earlier than v5.1.

When and if an attempt is made to downgrade from v5.1 to an earlier build, the older build will not be loaded. The printer will not accept the older operating system and will return to using the v5.1 or later version currently loaded on the printer.

The printer will provide feedback that the download is not supported, using one of the following methods:

  • On printers with a display screen, the message “Download Not Supported” will be displayed.
  • The lights on the printer will behave in the following way – the Status light will turn solid red. The other lights will be cycled on one at a time, changing the “on” light every second. (Exception: on the ZD500 series printer, only the Status light will turn solid red.)

The above chapters are taken from the Link-OS Release Notes P1105470-001.
