The ink cartridge wont stop in the right place for me to change them it keeps going straight across to the left and then across to the right and wont stop in right place

There may be a setting that requires you to select it in order to change the ink.
I went on Canon's website and they were less than helpful.

If the printer is out of ink in one or more cartridges (the ink light is steady), then with the printer on, lift the scanner unit and use the support to prop it up. Press the Stop button and the (first) empty cartridge will line up with the No Ink symbol on the printer. Press Stop again and the next empty cartridge will be moved to this symbol. Continue to press Stop until the cartridge carrier moves to the ink replacement position (depends on how many cartridges are empty). This is on the right side of the printer. Wait for the cartridge carrier to stop moving. Do not touch the white cable while changing the ink.

Next remove the first ink cartridge by pressing the two tabs towards the center of cartridge and pulling it straight up. (One tab is close to you and the other is closest to the printer.) Take your new cartridge for the slot and shake it four or five times. Then remove the cartridge from the package. Do not touch the green chip. Remove the yellow tape from the bottom of the cartridge. Next rotate the cartridge so that the nozzle is down and facing towards the inside of the printer. Then push it straight down into the slot until it snaps into place. Repeat these steps for the rest of the empty cartridges.

Once all of the empty cartridges have been replaced, lift the scanner unit and push the support to fold it. Close the scanner unit. Press Stop to start charging the ink system. Wait until the Power light stops flashing and remains on before turning off the printer or sending a print job to the unit.

If the Ink light continues to flash, open the scanner unit and press Stop. Press down on the cartridges to make sure that they are completely seated in the cartridge carrier.

If the ink out light is flashing or not lit, you need to use the Epson Utility to change the ink. This is part of the full software from Epson. For Windows right click on the printer icon in the taskbar (bottom right of the screen). Then select Printer Settings and click on the Maintenance tab. For a Mac, open the Applications folder and open Epson Printer Utility 3. Select your printer (if you have several Epson printers listed). Then click OK. (You will need to launch the utility before you open the scanner unit.)

The documentation for the Epson NX110 is available here: http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_SessionID=@@@@1663277658.1305218830@@@@&BV_EngineID=cceeadfdielfldicfngcfkmdhjidfmh.0&cookies=no&infoType=Doc&oid=128284&prodoid=63084353 .

I hope this helps.

Thank you!

You need to clean the encoder strip, it's the clear strip that runs across behind the carriage assembly. Use a Q-tip damp with alcohol and don't press too hard. With a light you'll see ink or grease spots that cause the carriage to lose it's place while moving across the page.

Aligning an Ink Cartridge You may need to align the ink cartridge when characters are not properly formed or are not aligned at the left margin, or when vertical or straight lines appear wavy.
To align the ink cartridge:

1. Load plain paper. For more information, see Loading Paper.
   
   
2. In Windows XP, click Start® Control Panel® Printers and Other Hardware® Printers and Faxes.
   
   

In Windows 2000, click Start® Settings® Printers.

1. Right-click the Dell AIO 810 icon.
   
   
2. Click Printing Preferences.
   
   

The Printing Preferences dialog box opens.

2. Click Align Print Cartridge.
   
   
3. Click Print.
   
   

A blue and black alignment page prints.

1. After the alignment page has finished printing, place the page face-down on the scanner glass. Make sure the upper left corner of the front of the page aligns with the arrow on the printer.
   
   

1. Press the Scan button .
   
   

The page is scanned. When the scan is complete, the cartridge is aligned. You may discard the alignment page when the alignment is complete.

Hope it helped.

It would help if you told us the printer make & model, however the easy way (for most inkjets) is to turn on the printer, when the carriage moves across simply pull out power cable or switch off at the wall socket. You can now push the carriage into the right position. Ensure it is pushed back the the park position before turning back on.

Please take a moment to rate this solution, thanks.

Disregard the monitor information and rely on the printer.

On the left panel of the printer are your indicator lights and buttons. Push the button immediately to the left of the 'ink drop' light [looks like a little tear drop]. Open the cover and the printhead assembly will move to the left and stop. Look very closely and find that little 'ink drop' imprinted into the plastic in the very middle of the printer where the printhead assembly stopped. That 'ink drop' will line up wih the ink cartridge that needs replacing. Push that button on the left again and the printhead assembly will either return to the 'replace' position, or move to the next ink cartridge that needs replacing. Keep pushing that button just once at a time until the printhead assembly identifies all cartridges that need replacing and moves into the 'replace' position. This 'replace' position will be on the right side of the printer where the opening occurs that allows the top cover of the printhead assembly to open.

Change the appropriate cartridges and you should be good to go.

With the power on and the lid up, click on the red stop (left panel). You will notice the cartridges move to the left and then they come back and stop halfway. Afterwards you should be able to slide the cartridges manually with your hand to the larger area on the right where you could do the cartridge change. Once you've moved it to that area just the lift the cover where the arrow is.

Hi-

Follow the steps below to replace one or more ink cartridges that are low on ink, expended, or too old:

1. Turn on the printer.

If you're replacing a cartridge before you see a message on the LCD display screen, press Setup, select Maintenance, and press OK. Then select Change Ink Cartridge and press OK.

2. Open the scanner.

3. Open the cartridge cover.

4. Squeeze the tab on the cartridge and lift the cartridge straight up to remove it. Dispose of it carefully. Do not take the used cartridge apart or try to refill it.

5. Before opening the new cartridge package, shake it four or five times. (Do not shake a cartridge after opening the package; ink may leak.)

6. Remove the cartridge from the package, but be careful not to touch the green chip on the cartridge.

7. Remove the yellow tape from the bottom of the cartridge.

CAUTION:
Do not remove any other labels or seals, or ink will leak.

8. Insert the new cartridge into the holder and push it down until it clicks into place.

9. Once you replace all the necessary cartridges, close the cartridge cover and push it down until it clicks into place.

10. Close the scanner.

11. Press OK to begin charging the ink. This takes about 2 minutes.
