Minimum skill level: 3

A fuse on the Electronics module has blown, normally caused by the X-axis motor or one of the motors on the Service Station. Follow the steps listed below to accurately determine the cause and replace the appropriate parts.

Tools required

• Ohm Meter
• Tester PCA (Included with new Electronics module)

Parts required (part numbers are subject to change)

Part description	2X00CP - C4703A, C4704A, C6085A	3X00CP - C4723A, C4724A, C6084A
Service Station Assy (Required)	C4723-60276	C4723-60276
X-Axis Motor Assy (Required)	C4724-60053	C4724-60053
Electronics Module (Required)	C4723-69114	C4723-69114

NOTE: If Removal and Installation instructions are needed for reference during any repairs performed, refer to the CP Series Service Manual available on the Computer Care Web site for review or download.

Troubleshooting steps

1. Turn the printer off, then on, to verify the system error.
2. If no error, verify printer functionality by printing several internal prints.
3. If error appears, continue with the checking the motors.

NOTE: The X-axis motor or one of the service station motors are the most suspected cause of the error, however; all motors must be thoroughly checked, as other failing motors may not have been detected.

Check all motors using Tester PCA and Volt Meter

1. Turn the printer off (using the power switch in back).
2. Connect the Tester PCA to the Electronics module (per the instructions shipped with the Tester PCA).
3. Hold down the Form Feed and Cut key and turn the power on.

NOTE: If the Form Feed and Cut key is not pressed when powering the printer on, the tester PCA will not function.

4. The Test PCA detects if there is a short in the DC motors (Carriage and media axis), stepper motors, or defective connections.
5. Note all failing motors/cables for replacement, and continue with Step 6.
6. Ohm all motors:
1. Check all motors by measuring the resistance values of the connectors.
2. Make sure that you check the resistance between pins 1-3 and 4-6.
3. If any of the motors are shorted, the value measured will be 0-5 ohms.
7. Replace the Electronics module, and all failed motors determined in any previous troubleshooting steps (refer to pg. 8-6 of the Service Manual).

CAUTION: If the Electronics module is replaced without replacing all failing motors, the new Electronics module will be burned.

NOTE: Following replacement of the Electronics module, the printer must be powered On in Normal mode to choose the appropriate language. Once the language has been chosen, turn the printer off, and continue with performing the necessary calibrations (listed below).

8. Perform calibrations C02, C03, and C08 (instructions listed below). All other necessary calibrations will be completed when printer is turned On in Normal mode (during printer initialization).

NOTE: Following each calibration, turn the printer Off to store the new calibration values in the EEROM. Turn the printer On (entering Service mode) to perform the next required calibration. Repeat this cycle until all necessary calibrations have been performed.

Performing Service Calibrations

Following each calibration, turn the printer off to store the new calibration values in the EEROM. Turn the printer on (entering Service mode) and perform the next required calibration. Repeat this cycle until all necessary calibrations have been performed.

1. Make sure the printer is turned off from the power switch on the back of the printer.
2. Hold the Up arrow key and the Enter key down while turning the printer on.

NOTE: Continue to press both the Up arrow key and the Enter keys until letters begin to scroll on the lower right corner of the front-panel display.

3. Once the message Status/Ready is displayed on the front panel, press Enter.
4. Use the arrow keys to scroll to the Utilities menu display and press Enter.
5. Scroll to Service Tests and press Enter.
6. Scroll to Service Calibrations and press Enter.
7. Use the arrow keys to scroll through the specific calibrations and press Enter when the required calibration is displayed.

NOTE: For the best results when performing the Accuracy calibration, use a Polyester Matte film. If Polyester Matte film is not available, use HP High Gloss or Heavy Coated media.

Verify printer functionality

Power the printer off, then on and perform several internal prints.
