e-studio 166 change region code

[TTL]

I have one Toshiba E-studio 166, who when I print the list, says that the region is 0001 (US), but should be 0044. How can I change that? I try compare with, see the service book, and can't find nothing to change this..
I want to change because this machine have some paper problems, like when I print or make a copy in A3 always jams. When I try to make a copy in A4, don't appear everything.. Etc.
How can I change the country/region?

1. Turn power off.
2. Press and hold [0] and [2] simultaneously while power on the machine.
3. Enter Region Code.
4. Press [Enter].
The machine will re-activate, wait a while for Ready Mode and that's all.

I believe that region code won't resolve your problem with jams.
There are 3 places in driver properties that should be changed to A3 size,
and you'll be able to print.

Region code does matter paper formats. 1 stands for letter, ledger and so on. 44 is MJD=Europe formats - A4, A3. As TTL says there are paper jams even in copy mode! Strange thing is that in both SH - for e166 and for e167, there are mentioned only CJ-High (e167) but no CJ-low (e166). Nevertheless 44 must be OK for e166.
