How do I replace the Carriage Cable? - HP Officejet 6310 All-In-One InkJet Printer

Congratulations, it probably has the best inkjet printer mechanics in the world. Anyway. The contacts in the carriage are tiny rods on springs. They can loose contact both in front due to ink, or in the back due to softened springs or oxidized carriage PCB. You have to dismantle the carriage to strengthen the springs and to clean their footprints. Second version: probably the flex cable from the main board to the carriage got cracks in the conductor and needs replacement. It happens often with old or heavily used inkjets/design-jets.

this is what i am finding out from other fixya site members so if this helps you out its them you need to thank...
Follow these steps :Cause: The Voltage of the print head is abnormal.
Problems can be with:
-Printhead -head relay PCB -Carriage relay PCB -Main controller PCB
Steps to be followed:
1. Replace the printhead. 2. Cable continuity check. if continuity of the cable between the head relay PCB and the carriage relay PCB is abnormal, replace the cable. 3. Replace the head relay PCB. 4. Cable continuity check. if continuity of the cable between the carriage relay PCB iand the main controller PCB is abnormal, replace the cable. 5.Replace the carriage relay PCB. 6.Replace the main controller PCB...
In my knowledge the error indicates the voltage on the print head is abnormal. It is an hardware related issue.

Possible cases can the print head is faulty or the relays to the PCB may be faulty or the PCB itself.

We have to perform continuity checks between the relays and between relays and PCB. then we can confirm if the relay is faulty or the cables between them . If not print head would have failed and needs to be replaced...

Problem with the Carriage PCA

Corrective action: Try the following:

1. Switch the power off from the back of the product and disconnect the power cord.

Reconnect the power cord and power on the product.

2. Check that the Trailing Cable is not damaged. Check that the Trailing Cable is correctly

connected between the Engine PCA and Carriage PCA.

3. Replace the Carriage PCA. See Carriage PCA on page 334.

4. Replace the Trailing Cable and Carriage PCA Covers.

5. Replace the Engine PCA. See EE Box on page 370.

The smoking and melting cable are the result of a short cicuit.
The problem is going to be determining which end the short is occuring on. It most likely is the carriage end of the cable that is the culprit. Most likely you will need to replace the carriage assembly and of course the trailing cable as the new one may have also been damaged.
You may need to use your fingers to check if the top of the carriage assembly (where the cable connects) is also getting hot (warmer than normal).

Hello,
this means that you have problem with carriage home position error.

This is displayed when the carriage homeposition sensor could not detect the
carriage within the prescribed time.

Some of things that needs to be checked or replaced:
1.Visual check
Remove any foreign objects adhering to the carriage contact section, carriage
homeposition sensor, linear scale, and linear sensor.
2.Carriage homeposition sensor
Check operation using SERVICE MODE>I/O DISPLAY, and replace if anything
does not function normally.
3.Cable connection check
Replace the cable between the carriage homeposition sensor and engine controller
if the connection is not functioning normally.
4.Replace the linear scale.
5.Replace the linear encoder.
6.Replace the engine controller.
7.Replace the system controller.

How to enter Service mode:
Follow the procedure below to enter Service mode.
1) Turn off the printer.
2) Turn on the printer while holding down the [PAPER SOURCE] button and [Online]
button.
3) Check that "Canon W72xx" is shown on the display, and then release the buttons.
4) Next, "SERVICE MODE" is shown on the display. (If sheets are inserted, this will
be displayed after the sheets are loaded.)
5) Use the [down arrow] button to make a selection.

Hope that helps!

From the service manual:

1. Remove the Left Hand Cover
2. Remove the Right Rear Cover
3. Remove the Right Hand Cover
4. Remove the Tensioner Assembly
5. Pull out Printhead Cleaner Carriage
6. Slide Carriage Assembly to position shown.
7. Lift up the Carriage Cover and remove ALL the Printheads and close the Carriage Cover.
8. Slide the Carriage along the Printer to the position shown.
9. Push in the 2 retaining clips either side of the Printhead Tube Connector.
10. Pull the Printhead Tube Connector towards you.
11. Push the button to release the Printhead Tubes in the Carriage.
12. Release the retaining clip by pulling it away from the holding brackets.
13. Pull the Printhead Tube Connector up between the two Tube Guides.
14. Slide the Carriage to the left side of the Printer.
15. Unclip and remove the Carriage Cover to access the Trailing Cable in the Carriage.
16. Carefully disconnect the Trailing Cable from the connectors in the Carriage PCA. NOTE Remove Trailing Cable
Ferrites if they fall into the Carriage.
17. Remove the Trailing Cables from the Trailing Cable Holder.
TIP Press the Trailing Cables firmly in the center to release.
18. Slide the Trailing Cable Guide out of the Carriage.
19. Slide the Carriage (including the Belt) to the left and out of the Printer.
20. Remove the Belt from the Carriage by releasing it from the retaining clips underneath the Carriage.


As you can see it looks to be a long process. I have the reinstallation instructions as well. If you still want to carry through with this, let me know and I'll send you the service manual....it will be easier than posting the text and the pictures that go along with each step.

Thanks and please take a moment to rate this solution as fixya.

Hi,

Please letme know what do you mean by Flex cable.

This error code is a Carriage motor error. Below is the outline for what to check and what to repair/replace. Good luck.

Cause
This is displayed when a jam or other physical problem puts an excessive load on the carriage motor so that the carriage could not operate.
This is displayed when the carriage motor could not reach the prescribed speed within the prescribed time.

Probable problem locations
Foreign object in carriage movement path, carriage rail, carriage belt, linear scale, linear encoder, carriage motor, engine controller, system controller


Remedy
1. Carriage movement path check
Remove any foreign objects (jammed sheet) in the carriage movement path.
2. Carriage rail
Use rail cleaner to clean the carriage rails if a visual check reveals that they are dirty.
3. Carriage belt
If a visual check reveals slack in the carriage belt, remount the belt.
4. Replace the linear scale.
5. Replace the linear encoder.
6. Replace the carriage motor.
7. Cable connection check
Replace the cable between the carriage motor and engine controller if the connection is not functioning normally.
8. Replace the engine controller.
9. Replace the system controller.
