Intermittent F87-03 and/or Printer Board Failure messages only when an IP421 is installed.DESCRIPTION: SOLUTION ID:
93457
SOLUTION:
CAUSE: During initial install, if the machine and IP unit are not allowed to boot up completely, the
code from the CF card(s) will not be written completely to the hard drive. This may occur if the
machine is powered OFF prematurely to access the 25, 36 or 47 adjustment mode. The code
written to the hard drive will be partial and the IP will be unable to boot the next time power is
applied.
SOLUTION: If unable to reformat the hard drive from the operation panel, remove the HD107 and
recover by installing it in a PC. Use a Microsoft* Windows 98 boot disk and the fdisk utility to clean
and reformat the drive on a PC. The following instructions explain how to use an IDE adapter to
attach the HD107 to a standard PC to reformat the drive:
1. [[A 2.5" laptop IDE hard drive adapter.| IMAGE V:\BITMAPS\IP411_HD_adapter.bmp SCROLL]]
This adapter can be found at most computer stores that sell a wide variety of cables and adapters.
One online source for this adapter is [[www.cablesonline.com| URL http://www.cablesonline.com]].
2. An IP controller or standard PC. The IDE adapter will need to be plugged into a standard IDE
