Control Board Assy. Removal

The Control Board Assembly has eight connectors to interface with external assemblies. A single connector (CN5) is used with the TwinAx/CoAx interface option as an external interface. The other seven connectors are used with board-mounted option assemblies. The daughter board also has three connectors which must be disconnected for board assembly removal.

CAUTION

CN15 and CN16 are identical in appearance, but are oriented differently. Reversing the two connectors could damage the printer.

1.Remove the following connectors from the Control Board:

∙CN2 Printhead

∙CN3 Stepper Motor

∙CN4 Operator Panel

∙CN6 Power

∙CN8 Bi-Cell Sensor (detector)

∙CN11 Bi-Cell Emitter

∙CN15 Ribbon Take-Up Motor

∙CN16 Ribbon Supply Motor

NOTE: CN3 is not readily accessible in its installed position. It is removed with the board partially lifted free.

2.Remove wiring at connectors CN3, CN6 and CN10 from the daughter board.

3.Move harness cables aside to allow clearance for board removal.

4.Slide AC inlet module boot back to access connectors.

5.Disconnect seven spade connectors at back of inlet.

6.Release the AC inlet retaining tabs and slide the AC inlet out the back of the printer.

7.Remove the AC inlet’s green ground wire from the frame to allow the module to clear the back frame.

8.Before removing the Control Board Assembly:

∙Verify the print assembly is in the closed and latched position.

∙pull the two yellow AC supply wires to the front side of the transformer.

∙reposition the parallel port latch wires inside the frame opening.

CAUTION

∙Do not bend the hall effect sensor (HALL1), located in the upper right corner of the board. The leaded device is fragile and can be bent or broken easily.

∙Use care not to scratch the back side of Control Board with the stand-offs, or the board could be damaged.

9.Remove three stand-off retainer screws located in connectors CN1,CN7, and below CN4.

10.Carefully pull the Control Board off the stand-off detents, while lifting it past the transformer wires to clear the large slot in the rear frame wall.

CAUTION

There is a large metal thermal heat sink on the bottom of the board. Snagging it on the AC inlet module boot or transformer wires can damage the equipment.

1.Remove stepper motor connector CN3.

2.Reassemble in reverse order except before seating the Control Board:

∙Reconnect stepper motor connector CN 3.

∙Feed the wire latches through the printer frame opening.
