Housing (Right/Left/Frame)

￿Removal procedure

1)Release CR lock lever toward the backside of the printer by the tweezer, and move CR unit from home position to around the center of the printer mechanism.

2)Remove Clamp core from [Mounting plate, M/B], and disconnect Head FFC from the connector on main board. Then, release Head FFC from Holder shaft unit.

￿Shield plate FFC on Head FFC is pasted on [Mounting

CAUTION	Plate, M/B]. Therefore, you have to remove Shield plate
	FFC with Head FFC carefully.

3)Loosen one screw for securing Stopper holder pulley driven to main frame & CR timing belt by pushing Driven pulley holder to the right side, and release CR timing belt carefully from CR motor pinion gear.

4)Remove CR encoder scale from main frame.

5)Release one hook for securing Cover cable head to CR unit, and remove Cover cable head with pushing it down .

6)Release two hooks for securing IC holder to Print head assy.by the tweezer, and pull IC holder until the holder contacts Front frame.

7)Return CR unit to home position before removing Front frame.

8)Remove two screws for securing Front frame to main frame.

9)Lift up the left side of Front frame slightly, and slide the frame toward the front side of the printer.

10)Move CR unit to the center of the printer mechanism with holding the whole of the unit by hand.
