Text Mode
The following SP modes select the MTF filter coefficient and strength in the main
scan direction for text mode.
• SP4-903-20 to SP4-903-23 (25%~64%)
• SP4-903-24 to SP4-903-27 (65%~154%)
• SP4-903-28 to SP4-903-31 (155%~256%)
• SP4-903-32 to SP4-903-35 (257%~400%)
NOTE: Increasing this value strengthens MTF but can also increase the
occurrence of moiré and reduce sharpness.
