1.2 Quiet mode

By feeding and ejecting paper gently and suppressing the sound from mechanical parts,
printing noise can be suppressed. This setting (including specific operation hours) can
be made from the driver when the printer is connected.

1.2.1 Quiet mode limitations

(1) Lowered throughput

Since the speed of paper feeding and ejection is slower, throughput is lower.

(2) Settings reset at power OFF

The Quiet mode setting is not stored within the printer itself (in the EEPROM), so
that it will be reset (turned off) when the printer is powered OFF.

1.3 Remaining-ink amount detection (S900/S820)

The remaining-ink function determines whether there is ink in the ink chamber
(yes/no) and uses dot-count logic to display the amount of ink remaining in the ink
chamber.

1.3.1 Limitations when using the remaining-ink amount detection function

The amount of remaining ink may not be displayed accurately due to dot count error
margins or ink tank replacement.
