# Cautions after assembling

Caution / 注意

The ink-path-related components or parts should be firmly and securely reinstalled on the printer to prevent the ink from leakage. When reassembling the printer, make sure to connect the connectors of the electric components or parts correctly and securely. Use extreme care when connecting FFCs (flexible flat cables). Improper connection of the FFCs, such as inserting them diagonally into the connectors, could cause shortcircuiting and lead to breakdown of the electric elements on the boards. When reassembling the printer, make sure to route the FFCs and other cables as specified in this chapter. (Failure to do so may cause an unexpected contact of the cables with sharp metal edges, or lead to lower the noise immunity.) When you removed any parts (especially cables) that are secured with acetate tape or two-sided tape, be sure to reinstall and secure them with the tape as exactly the same as they were.
