How do I get the carriage to move awayfrom the right side of the printer?

Hello,Lester Makang
Your carriage got stuck in service station,is there any noise coming from the right side of printer then there will be broken gear.
Power on your printer,after you got carriage jam error open cartridge access door and wait 5 second when you see that gears trying to move,use your hand to pull your carriage to left side.Don't use much force.If your carriage got free then install your print head and cartridges.If this will happen again then take it to service center they will change the service station or broken gear but the cost goes much high.

it will be stuck in roller cleaner mode, that is mechanical. the only real way is to push it thether over to the left. with the power off the printer, then close the compartments and turn on the printer it can take 2 o3 goes as it will try to move it right. you have to get it off the clip that is holding it there. the cartridge is held in place to stop it moving while the roller is cleared.

You might wanna try removing and reinserting the cartridges and make sure that they are properly fitted in.
Sometimes cleaning the cartridge and the carriage where you took out the cartridges from with a damp lint free cloth does the trick.
If you still have that message, open the cartridge access door.
If the carriage is stuck at the right side of the printer, move the carriage to the left side by hand. If it's stuck on the left side, try moving it by hand in the right side of the printer. Then while the printer is turned on, unplug it from the wall outlet and then plug it back in.
If the printer does not turn on, use the power button.
Try printing again.

You would want to try and reinstall the print cartridges. It is possible that something is just stuck that is why you are hearing the grinding sound.
Let me know.

It's probably jammed by dirt. Unplug the printer, move the carriage out of the way and clean thoroughly the metallic rails the carriage runs to using a cue tip.You might have to move the carriage multiple times to clean it totally. Finally spread a little fine grease over the metallic rail and again move the carriage from side to side. Now plug it in and try using it.

The print carriage may get stuck on either side or in the middle of the printer. The Carriage Jam: Open Door, clear carriage jam, and then press OK to continue error message may display on the front panel of the all-in-one.

Solution
The print carriage is the device which contains the print head and moves left to right during printing.
Figure 1: Carriage Assembly

To resolve this issue, follow the steps below in the order presented.

Step one: Print a Self Test

Follow the steps below:
1. Press the Setup button.
2. Select Print Report and press OK .
3. The self-test page should print. If it prints a test page, there is no need to follow the remaining steps, as the error message may be false. Make sure the printer now prints from the computer (if installed on one). If it does not print, proceed to the step two.

Step two: Clear the paper path

Follow the steps below to clear the printer of any jammed paper and reset the printer.
1. Leave the printer on and then disconnect the power cable and the USB or Ethernet cable from the back of the printer. Do not reconnect them until instructed to later.

NOTE: Make sure the printer is on before disconnecting the power cord. Failure to disconnect the power cord from the rear of the unit can cause damage when removing jammed paper.

2. Open the top access door.

Figure 2: Opening the top access door

3. Make note of where the carriage is stuck and look for jammed paper. A paper jam can cause the error message and the carriage stall. Some paper may be jammed in different locations than those shown in the photos below.

Figure 3: Paper jammed on the left side

Figure 4: Top view of paper jammed on the left side

Figure 5: Paper jammed on the right side

Figure 6: Top view of paper jammed on the right side

NOTE: Do not use any tools or other devices to remove jammed paper. Always use caution when removing jammed paper from inside the unit.

If the carriage is stuck on the right side:
a. Check for any paper or object that may be restricting the carriage.
b. Move carriage all the way to the left side.
c. Check the paper path all the way to the right side and remove any paper still in the printer.

If the carriage is stuck on the left side:
d. Check for any paper or object that may be restricting the carriage.
e. Move carriage all the way to the right side.
f. Check the paper path all the way to the left side and remove any paper still in the printer.

If the carriage is stuck in the middle:
g. Check for any paper or object that may be restricting the carriage.
h. Move carriage all the way to the left side.
i. Check the paper path all the way to the right side and remove any paper still in the printer.
j. Move carriage all the way to the right side.
k. Check the paper path all the way to the left side and remove any paper still in the printer.
4. Remove the rear access door or duplexer (if installed) from the back of the printer.
5. Check for and remove any paper still in the printer.
6. Replace the rear access door, and close the top access door.
7. Reconnect only the power cable. If the printer does not automatically turn on, press the Power button.

NOTE: The printer may go through a warm-up period of up to two minutes. Lights may flash and the carriage may move. Wait until this warm-up period is complete before going to the next step.

8. If the Power light is on steady, print a self-test page as done in Step one.

If the Power light is not on steady and the carriage is still in a stalled position, proceed to the next step.

Step three: Plug the printer directly into a wall outlet

Verify that the printer is properly connected to a suitable power source by following the instructions below.
1. Verify that the computer and the printer have a three-prong power plug.
2. Remove the printer cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
3. Try the print job again to see if this step resolved the issue.

NOTE: If the printer prints when plugged directly into a wall outlet while disconnected from any power strips or surge suppressors, the power strip or surge suppressor may not be allowing sufficient voltage to reach the product.

4. If this did not resolve the issue, proceed to the next step.

Step four: Service the product

If you have completed all of the steps listed above and are still experiencing a problem, service your product.hope this helps
