2.1 Print Engine Control
2.1.2 Print Engine Modes
Figure 2–3 shows the activity that occurs during the following DEClaser 5100
operational modes:
1. When the printer is powered on, the printer enters the wait mode and:
• Turns on the fusing heater and monitors the temperature rise.
• Checks the top door and rear door closed sensors
• Makes sure the selected feeder is installed and loaded
• Checks the EP-ED cartridge and toner empty signal
• Runs the main and scanner motors
• Turns the high-voltage bias supplies on and off
• Cleans the transfer roller
2. If all the wait checks pass, the printer enters standby STBY mode
until a print request is received. During standby, fusing temperature
and interlocks are maintained. Standby ends when a print command is
received from the video controller or from the test print switch.
3. After a signal is received, the printer enters the initial rotation
(INTR mode) which lasts approximately six seconds. During this period
the fusing temperature is raised, the main and scanner motors come
up-to-speed, and the print drum stabilizes.
