This is the reversed engineered HP Laserjet 4P printer. Materials used for the contruction are mild steel stamppings, injection molded plastic housing, precision machine screws, glass use for the lens, silicon for the semiconductors ICs etc.
Paper for some of the PCBS, aluminium for the fuser assembly, copper for the interconnection wires and PCB foil, some chemicals used in the larger capacitors, soft iron for the transformer, ferrite for the high frequencies transformers,
clever engineering.
Wonder if the King's men and horses could help to put the printer back again. The screwdrivers and plier are the tools use in the reverse engineering study.
