Image Writing

6
This machine uses an LPH (LED Print Head) [A] that sends light directly to the OPC drum to make a latent
image.
The A0-size 600-dpi print head is an array of connected self-focusing lenses [B] above an LED array [C]
and drive board [D], and attached to a heat sink [E].
• The maximum printing width of the print head is 914 mm (36").
The LPH has three sections: LPH 1, LPH 2, and LPH 3. The two joints between the sections are identified as
"LPH 1-2" and "LPH-2-3" (see above).
