2.2.4.3 Paper Mode Setting
The paper mode that matches the print medium is selected according to the statuses of
the PE sensor, CD-R sensor (Only for Stylus PHOTO 2100) and Release lever (sensor)
to determine the paper loading sequence (paper locating control). The following table
indicates the relationships between the sensors and paper modes.
Note: Panel switch operations change depending on the selected paper mode.
When the PE sensor detects paper after operation of the Release lever, pressing the Paper
feed switch causes the PW sensor to detect the leading edge of the paper and the printer
to perform paper locating control and enter the standby status.

Wait time
Photo-ink (HCD ink: Photo-black, Light-black) is easy to dry, but Matte-ink (PPI
ink: Matte-black) is difficult to dry. For the medium that uses Matte-black,
therefore, paper is transferred after a maximum of 2 second wait time has elapsed
after printing according to paper loading amount conditions.
"
Waiting conditions
1. When the paper loading instruction is 2672/1440 steps or more, paper
loading starts after the wait time.
2. When the paper loading amount is less than 2672/1440 steps, the time
taken between paper loading and printing up to the roller is estimated so
that the time to reach the roller will be the wait time.
