necessary. Saving place of adjustment value is selected as following list.

Note *1: For the other PG settings (for 0.7/2.1/2.6), overwrite the values adding a
offset value if the set value in the user area and the default values are the
completely same with each other. If the PG setting differs in any one of eight
colors, do not overwrite the current settings because the difference means
that the user has changed the setting.
*2: Even when paper thickness sensor detects thin paper (less than 0.8mm), PG
is set as 2.6mm if paper thickness setting is more than 0.7mm.
*3: When paper thickness sensor detects thick paper (more than 0.8mm), PG is
set as 2.6mm regardless of PG setting and paper thickness setting.

thickness setting command PH.
