Size Code from 0 to 11 uses 1 Block, 12+ occupies multiple blocks.

"Size Code 12" occupies 2 Blocks and this can be set to even Block numbers. If you try to set this to an
odd Block number, it is set to the previous Block number.

The Block after the one you set to "Size Code 12" is also treated as "Size Code 12". This number does not
appear in the Block selection.

For example, if you try to set Size Code 12 to Block 3, it is set to Block 2. Then the Block 3 is skipped
because Block 2 is set to "Size Code 12". Block 2 and Block 3 are treated as "Size Code 12". Then the
scanner advances to Block 4 to select its Size Code.

"Size Code 13" occupies 4 Blocks and this can be set only for Block 0 or Block 4. If you try to set this to
Block number 1 - 3, it is set to Block 0. And if you try to set this to Block number 5 - 7, it is set to Block 4.

When you set a block to "Size Code 13", the following three blocks are also be treated as "Size Code 13".

The "Size Code 14" occupies all 8 Blocks. So, this Size Code can only be set for Block 0. If you try to set
this to another Block, it is set to Block 0. Then only the Block 0 is displayed. All Blocks are treated as
"Size Code 14".

If you change a Size Code from these 3 Codes to a Size Code which occupies a fewer number of Block,
the scanner sets the other Blocks to "Size Code 0".

For example, if you changes the Block 0 from "Size Code 13" to "Size Code 5", the setting of Blocks are:
Block 0 = Size Code 5, Block 1 - 3 = Size Code 0.
