After Replacement - Toshiba e-STUDIO206L Service Manual

7.5.5 To allow the equipment to detect a recycled unit as a new one

after replacement

To recycle an old EPU after replacement and also let the equipment detect that it is a new one, the
supply items in the EPU and the IC chip data in the EPU board must be replaced.
In this case, the EPU board itself must be replaced with a new one (service part) or the IC chip data
must be overwritten using a jig.
If the EPUs are replaced in the PM support mode instead of the EPU replacing mode noted in this
chapter, the replacement of the EPU board and the overwriting of the IC chip data are not necessary.
Information in the IC chip can be confirmed with 08-4555 (Information check of new or old EPU
memory). The display of [0xff00(NEW)] indicates a new IC chip while [0x00ff(OLD)] indicates a used
one. A hexadecimal value ending with "-" indicates that invalid data have been entered. In this case,
rewriting with a jig is required.
