4.1.1 Cover Removal
Before removing any covers ensure that the supplies (air and electrical) have been isolated from
the printer.
4.1.1.1 Earth Bonding
All external metal surfaces are mechanically and electrically bonded to the printer earth point. The
bonding wire used is identified by its green and yellow insulation and is commonly used to earth
bond throughout.
Using an 8mm spanner, remove the two earth lead securing nuts and washer. Detach the earth
lead from the panel.
Care should be taken when removing these links, to ensure that when they are replaced they are
secured tightly and cleanly.
4.1.1.2 Locating Pins
Side, corner, front and rear panels are secured on location pins at the base of the printer. Plates
mounted on each corner of the printer (see vignette below) house the pins.
