1.2 Quiet modeBy feeding and ejecting paper gently and suppressing the sound from mechanical parts,printing noise can be suppressed. This setting (including specific operation hours) canbe made from the driver when the printer is connected.1.2.1 Quiet mode limitations(1) Lowered throughputSince the speed of paper feeding and ejection is slower, throughput is lower.(2) Settings reset at power OFFThe Quiet mode setting is not stored within the printer itself (in the EEPROM), sothat 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 inkchamber.1.3.1 Limitations when using the remaining-ink amount detection functionThe amount of remaining ink may not be displayed accurately due to dot count errormargins or ink tank replacement.Part 3: Technical Reference S900 / S820 / S750 / S5203-2Dot countSensor detectionDot countInkchamberRemaining-ink amount display(100/70/40%)Ink low warning(10%)Ink out errorFigure 3-1 Remaining-ink amount detection
