Summary:
 Flash code upgrade for KIWI interface board.

Resolution:
 The newer 4000 series of printers use the Kiwi (MIPS) board as the interface controller. Depending on the Kiwi microcode, the printer can have QMS/IGP, SCS, IPDS, coax, twinax, parallel, serial or any combination of interfaces and features.

The Kiwi board comes in two models- the Kiwi (AKA Kiwi Senior), and the Kiwi Junior (AKA Peewee). The Kiwi can be upgraded by a flash load, the Kiwi Junior cannot.

To identify the type of Kiwi board installed in the printer:

- Print a status page:
- Take the printer off-line.
- Press FUNCTION.
- Press PREVIOUS OPTION- the display shows STATUS.
- Press ENTER- the status page prints.
- Press QUIT to exit Function Mode.

- Near the end of the status page is a section titled Controller Status Report. This is the Kiwi status. The Kiwi will have an entry near the end of the report for Upgrade- the Kiwi Jr will not. 


To upgrade the flash code on the Kiwi board:

- Requirements:
  IBM PC or compatible computer with a parallel port
  A standard or IEEE-1284 parallel cable.
  Kiwi upgrade file.
  At least 1 Megabyte of available hard disk space on the PC.
  NOTE: The upgrade cannot be performed from a floppy.

- Disconnect all inputs to the printer: parallel, serial, coax, twinax, and network.

- Connect the printer to the parallel port on the PC.


NOTE: Ensure that the LPT port is *not* redirected. The port may be redirected if the printer is on a network. If Windows is running, exit Windows before performing the upgrade.

- Place the printer on-line and verify communications between the printer and the PC. From the DOS prompt, type:

   DIR >LPT1

If the directory does not print properly, turn the printer power off and on, and verify communications again.

CAUTION: If there is a problem with communications between the printer and the PC do *not* proceed until the problem is resolved.

- On the PC, change to the folder in which the the upgrade file is located.

NOTE: The upgrade file has a file extension of LOD. If the file was distributed in EXE format, run it to extract the LOD file.

- Place the printer in upgrade mode: 


  Take the printer off-line.
  Press the PROGRAM key.
  Press PREVIOUS OPTION- the display shows CONTROLLER.
  Press ENTER.
  Press NEXT OPTION until the display shows UPGRADE.
  Press ENTER.
  Press QUIT.
  Press ONLINE- the display shows UPGRADE READY.

- From the DOS prompt, type 

	COPY /B xxxxxx.LOD LPT1

WHERE: xxxxxx is the name of the upgrade file.

NOTE:  Substitute LPT2 for LPT1 if needed.

CAUTION: Do not turn off the printer power or interrupt the upgrade process.

- The printer display will show the status of the upgrade.

- When the upgrade is complete, the printer will reboot.
