Alignment problems can?t get me Epson CU6400 alignment fixed. I print out the alignment sheet and all the choices are out of line, none match up with each other. What can I do to fix it. I think I have the same problem. I wish there was a way to restore the default factory settings. It seems that each time I re-run the test, it gets worse. The "redo test" suggestion is not helpful. The lines are so squiggly, there ARE NO "BEST" aligned samples.

This issue is usually caused by miss-aligned cartridges or failing cartridges.
Try re-aligning the cartridges by going through the setup and selecting option to realign.

1. Press the Menu button.
2. Press the up or down arrow buttons to select Maintenance and press the OK button.
3. Press one of the button to print an alignment sheet. Note: Do not cancel printing while you are printing a head alignment pattern.

This alignment can also be done using utility software for this printer.

If alignment does not fix the issue then try cleaning cartridge before replacing them. Procedure for cleaning is the same as above.

Sounds like the paper might be damp

If your printed pages have a horizontal line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned

Every time you replace ink you need to do an alignment. To do this follow these simple steps:

1. Press the Ink or Ink Management key on the control panel.
   
   
2. Press the up or down navigation key to select TEST PRINT and press Menu/Set or Set.
   
   
3. Press the up or down navigation key to select ALIGNMENT and press Menu/Set or Set.
   
   
4. Press Black (Mono) Start or Color (Colour) Start. The machine begins printing the Alignment Check Sheet.
   
   
5. By reviewing this Test Sheet, you can determine if the alignment needs adjustment.
   
   
6. Examine the 600 DPI and 1200 DPI test prints on the Alignment Check Sheet. If the number 5 sample of both the 600 DPI and 1200 DPI most closely matches the 0 sample, press 1 (YES).
   If one of the other samples is a better match for the 0 sample, press 2 (NO). The display will then prompt you to select the sample that most closely matches the 0 sample for 600 DPI and then 1200 DPI.
   
   
7. Press Stop/Exit.

Check the alignment. Press the key for Ink or Ink Management on the Control Panel. Select Test Print (the up/down arrows) and hit Menu/Set or Set. Select Alignment and press Menu/Set or Set. Next hit Mono (Black) Start. Look at the Alignment Sheet that prints out. Press 1 if the number 5 sample matches line 0 for both 600 and 1200 DPI samples. Press 2 and then the number for the line that matches that matches the 0 sample.
Then press Stop/Exit. Repeat this for color printing by using the Color button.

You should also check the Print Quality. (Very similar menu choices - just choose Print Quality after choosing Test Print but you only need to hit the Color button to print the test sheet.) This will initiate a cleaning cycle for any poor quality ink test pattern. You will need to respond Yes or No for the print quality and each ink (if you answered No). If you do the cleaning 5 times with problems, replace the cartridges in question.

Finally try cleaning the printhead (Press Ink or Ink Management and then 1 for cleaning) If 5 repeats do not help, contact Brother support, the print head may need to be replaced. (Unfortunately, this isn't the only reason for the problem. Once you put in a print head, it isn't returnable. It could be that the entire printer is ready for recycling.)

I hope this helps.

I hope this resolves your problem.

Check if the charge corona cleaner is pushed all the way to the end. If not, it will leave a black bar on all images.

Try selecting the closest set of line(s) and redo the test .

I have figured it out! I have a Brother MFC 240CN and I was having the same alignment problem and I followed the instructions from the printer prompt as well as the manual and it does not work.

So, this is what I did. I ran the alignment test print, then when it asked if it matches, I would say "No". And then I would pick number "8" to be the one that most closely matched "0" regardless if it did or not. I did this for the 600 and 1200dpi. Then when I ran the alignment test print again, it looked better! So I repeated it again and again picking "8" each time and it looked better with every test print. After about 4 or 5 tries, it looked normal again!

I hope everyone else with this problem will see this response and I hope it works too. I was getting so frustrated with this problem. Now I don't have to get it serviced or buy a new printer!
