*1: External temperature is measured (temperature/humidity sensor) when the main switch is
turned on and when a job start signal is received.
*2: The pressure and heating rollers start idling.
*3: Fusing idling stops when both roller temperatures reach the print ready condition. The
printer can process jobs when the rollers reach this temperature during warm-up.
*4: A user tool (User Tools - System Settings - Tray Paper Settings - Paper Type) specifies the
paper type in each tray (plain, thick, or OHP). If "plain" is selected, then another user tool
(User Tools - Maintenance - Plain Paper Type) defines whether the paper in the tray is
"normal" or ">90 g/m2, 24 lb". (☛ 5.1.2). ">90 g/m2, 24 lb" means "greater than or equal to
90 g/m2, 24 lb".
• "Thick" means paper heavier than 105 g/m
*5: Both sides of the paper are processed with the same roller temperatures.
*6: Use SP1-105 to adjust the default fusing temperatures (☛ 5.1.2).
