Shield
Figure 188. Lower Plastic Shield - Two Piece Version. Attaches to Support Assembly
If the printer has a one-piece version, the entire Lower Plastic Shield/Support Assembly must be removed
regardless of the damage. Go to "Removal - One-Piece Version". The two piece version will be installed as the
replacement. See "Replacement - Two-Piece Version" on page 456.
If the printer has a two-piece version and the failure is only the damaged plastic shield, the plastic shield
assembly can be exchanged without exchanging the entire Lower Plastic Shield/Support Assembly. Go to
"Removal - Two-Piece Version" on page 455.
If the printer has a two-piece version and the failure is something other than a damaged plastic shield, the entire
Lower Plastic Shield/Support Assembly must be exchanged. Go to "Removal - One-Piece Version".
