Special Mode M

Sets to improve print quality or fix irregular print density. If 
print quality decreases or an irregularity in the print density 
appears, transcription output may not function adequately.

Standard

Normal transcription output.

Low

Lower than normal transcription output.

Selecting [Low] may be effective when printing on paper that 
contains a lot of moisture because it was stored for a long period of 
time after opening, or when printing on recycled paper.

Moderate

Slightly higher than normal transcription output.

High

Higher than normal transcription output.

Selecting [High] may be effective when printing on the 
heavyweight paper.

Special Mode N

Sets whether to prevent paper curls or jams which may occur 
when printing on paper that has absorbed moisture.

Do not use paper that has been exposed to high temperature or 
humidity for an extended period of time. Printing on such paper 
will frequently result in a paper jam.
Printing times with Special Mode N activated are longer than 
when the function is not used.
If you select [Medium] or [High] when paper is not moistened, the 
print quality may be deteriorated.
