These are the most important components around the drum.
The paper passes the drum at 120 mm/s (D046/D154) or 170 mm/s
(D049/D155). However, the fusing motor pulls a little faster. This will be
discussed in the Fusing section of the course.
The drum diameter is 80 mm.
This means that the circumference is about 251.4 mm.
The charge corona unit has widely-spaced grid wires, like some previous wide-
format copiers.
The machine prints with LEDs, not a laser beam. The LPH (LED Print Head)
consists of three A3-width LED arrays, to allow A0-width printing.
A single A0 LED array is very costly, so three A3 arrays are used. This is
discussed in more detail in the Exposure section of the course.
