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 ceter of the printer

 

mechanism.

2)

Loosen one screw for securing Stopper holder pulley driven to main frame &

ADJUSTMENT ￿

REQUIRED

￿Do not damage CR motor pinion gear with main frame.

￿Make sure to connect the CR motor connector cable to the connector (CN5) on main board.

￿Make sure to place CR motor connector cable to Holder shaft unit properly.

￿Fasten two screws for securing CR motor in the order/ tightening torque indicated in the figure.

￿Make sure that there is no gap between CR motor and frame main.

￿Make sure to set CR motor upward the serial no. of the motor.

￿Make sure that two dowels of Clamp core is set in home position direction.

￿Make sure that PE sensor cable & CR motor connector cable are set on Holder shaft unit, and in Clamp core.

When CR timing belt is removed or replaced with new one, tension adjustment of CR timing belt must be performed by the degital tension gauge.

 

CR timing belt by pushing Driven pulley holder to the right side, and release

 

CR timing belt carefully from CR motor pinion gear.

3)

Disconnect CR motor connector cable from the connector (CN5) on main

 

board, and release CR motor connector cable from on Holder shaft unit.

4)

Remove two screws for securing CR motor while holding the motor by hand.

￿When removing CR motor from main frame, do not damage

CAUTION

the pinion gear of the motor.

 

￿When CR motor is removed or replaced with new one, the following adjustment must be performed in the order below.

1)Top margin adjustment

2)PF adjustment

3)Bi-d adjustment

4)Head angular adjustment

5)1st dot adjustment

6)PW sensor adjustment (Only for SC83/84)

7)CR motor drive torque dispersion measurement
