Connector Shells Note Connector Shells Some of the cable connectors in the printer are grouped inside connector shells. The procedure below explains how to remove and install cable connectors from connector shells. There is also a diagram of the P106 and P107 connector shells on the plastic heat shield over the power supply. Removal 1. Prepare the printer for maintenance (page 100). 2. Cabinet Models: Remove the paper path (page 161). Pedestal Models: Remove the top cover assembly (page 142). 3. Remove the stiffening clip (page 133). 4. Disconnect the cable connector shell containing the cable assembly that you will replace. 5. Pull the side of the connector shell outward and gently pull the cable connector upward. (See Figure 18.) Notice that two-wire connectors are grouped across from two-wire connectors in a connector shell. Four-wire connectors are grouped across from four-wire connectors in a connector shell. 6. Disengage the key tab(s) on the cable connector from the slots in the side of the connector shell. 7. Remove the cable connector from the connector shell. (Remove only the cable connector for the cable you are replacing; leave the other cable connectors in the shell.) Installation 1. Position the cable connector in the connector shell. Two-wire connectors are always grouped across from two-wire connectors in a connector shell. Four-wire connectors are always grouped across from four-wire connectors in a connector shell. (See Figure 18.) 2. Pull the side of the connector shell outward and gently push the cable connector down into the connector shell. 3. Engage the key tab(s) on the cable connector in the slots in the side of the connector shell. Press the sides of the connector shell inward to make sure all cable connector tabs are engaged in the shell slots. 4. Install the stiffening clip (page 133). 5. Connect the cable connector shell to its printer connection. 6. Cabinet Models: Install the paper path (page 161). Pedestal Models: Install the top cover assembly (page 142). 7. Return the printer to normal operation (page 101). 131

Connector Shells

Connector Shells

Some of the cable connectors in the printer are grouped inside connector

shells. The procedure below explains how to remove and install cable

connectors from connector shells.

Removal

Prepare the printer for maintenance (page 100).

Cabinet Models: Remove the paper path (page 161).

Pedestal Models: Remove the top cover assembly (page 142).

Remove the stiffening clip (page 133).

Disconnect the cable connector shell containing the cable assembly that

you will replace.

Pull the side of the connector shell outward and gently pull the cable

connector upward. (See Figure 18.) Notice that two-wire connectors are

grouped across from two-wire connectors in a connector shell. Four-wire

connectors are grouped across from four-wire connectors in a connector

shell.

Disengage the key tab(s) on the cable connector from the slots in the side

of the connector shell.

Remove the cable connector from the connector shell. (Remove only the

cable connector for the cable you are replacing; leave the other cable

connectors in the shell.)

Installation

Position the cable connector in the connector shell. Two-wire connectors

are always grouped across from two-wire connectors in a connector shell.

Four-wire connectors are always grouped across from four-wire

connectors in a connector shell. (See Figure 18.)

Pull the side of the connector shell outward and gently push the cable

connector down into the connector shell.

Engage the key tab(s) on the cable connector in the slots in the side of

the connector shell. Press the sides of the connector shell inward to make

sure all cable connector tabs are engaged in the shell slots.

Install the stiffening clip (page 133).

Connect the cable connector shell to its printer connection.

Cabinet Models: Install the paper path (page 161).

Pedestal Models: Install the top cover assembly (page 142).

Return the printer to normal operation (page 101).

There is also a diagram of the P106 and P107 connector shells on the

plastic heat shield over the power supply.

Note
