An error has occurred in finding the Primer home position. The most common cause of this issue is the Primer that is attached to the Service Station assembly. Follow the steps listed in this document to accurately determine the cause and replace the appropriate parts.

Parts required (part numbers are subject to change)

Part description	Model numbers C4703A, C4704A, C6085A	Model numbers C4723A, C4724A, C6084A

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

If parts are replaced or fixed in any of the steps listed below, attempt to verify printer functionality by turning the printer on and printing internal test prints. If functionality is verified, no additional parts should be replaced.

1. Turn the printer off using the power switch located on the back of the printer.
2. Remove the right end-cover from the printer.
3. Manually turn the X-axis motor gear (on Service Station assembly) to move the Service Station toward the front of the printer, refer to Figure 1.

4. Locate the primer motor shaft (refer to Figure 2).

Figure 2: Primer motor shaft

5. Manually turn the primer motor shaft until two distinct clicking noises are heard.

NOTE: Primer motor shaft will only turn one direction.

6. Turn the printer on, and allow printer to initialize.
7. If no error is reported, verify functionality by printing several internal prints.
8. If the error reappears, continue with the remaining steps listed below.

Perform the D05 Service Station Diagnostic Test

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 and turn the power on.

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

3. Once the message "Status/Ready" is displayed, press Enter.
4. Use the Arrow buttons to scroll to the Utilities menu and press Enter.

NOTE: Full menu mode must be set to access the Service Tests submenu. In the Utilities menu, scroll to Menu Mode and select Full.

5. Use the Arrow keys to scroll to the Service Tests menu display and press Enter.
6. Use the Arrow keys to scroll to the Diagnostics menu display and press Enter.
7. Using the Arrow keys, scroll to D05 Service Station and press Enter.
8. If the test passes, the Primer and Service Station assemblies are functioning correctly. Turn the printer off, then on and verify functionality by printing several internal prints.
9. If the test fails, or problems persist, replace the Service Station assembly (refer to pg. 8-26 of the Service Manual).

NOTE: No calibrations are required following the replacement of the Service Station assembly.

10. Verify printer functionality by turning on the printer and printing several internal prints.
11. If after replacing the Service Station assembly the error reappears, continue with Step 12.
12. Replace the Electronics module (refer to pg. 8-6 of the Service Manual).

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

13. 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.
