  • Page 140 S900/ S820/ S750/ S520 Part 3: Technical Reference 1. NEW TECHNOLOGY 1.1 Borderless printing To allow printing of the entire paper surface, and an area exceeding the paper surface, borderless printing has been enabled. The difference from printers to date not capable of borderless printing is that the paper size may or may not need to be set in the application being used.

  • Page 142 S900/ S820/ S750/ S520 Part 3: Technical Reference 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.
