Print Head Maintenance


If your printouts become too light, or you see dark or light bands across them, you may need to clean the print head nozzles. Cleaning uses ink, so clean the nozzles only if print quality declines.
You can check for clogged nozzles before you clean them so you don’t clean them unnecessarily.
Note: You cannot clean the print head if an ink cartridge is expended, and may not be able to clean it when a cartridge is low. You must replace the cartridge first.
 

Print Head Nozzle Check

You can print a nozzle check pattern to check for clogged nozzles. 

Checking the Nozzles Using the Product Control Panel

You can check the print head nozzles using the control panel on your product.

  1. Make sure roll or cut sheet paper is loaded in the printer.
  2. Make sure the correct paper type is selected.
  3. Press the Menu button.
  4. Press the up or down arrow button to select Maintenance and press the right arrow button.
  5. Select Nozzle Check and press the right arrow button.
  6. Press the OK button. The nozzle pattern prints.
  7. Check the printed pattern to see if there are gaps in the lines.
    Note: Use at least a 10× eye loupe to examine the pattern for any missing or deflected dots or segments.
    1. Print head is clean
    2. Print head needs cleaning
  8. Do one of the following:
    1. If there are no gaps, select Exit and press the OK button.
    2. If there are gaps or the pattern is faint, select Head Cleaning and press the OK button.
  9. Follow the instructions on the screen to clean the print head, check the nozzles, and repeat the process as necessary.


Print Head Cleaning

If print quality has declined and the nozzle check pattern indicates clogged nozzles, you can clean the print head. Use the nozzle check pattern to determine which colors need cleaning. You can save ink by cleaning only selected colors (control panel only).
Note: You cannot clean the print head if an ink cartridge is expended, and may not be able to clean it when a cartridge is low. You must replace the cartridge first.

Print Head Alignment

If your printouts become grainy or blurry, you notice misalignment of vertical lines, or you see dark or light horizontal bands, you may need to align the print head. You can align the print head automatically from the control panel or your computer, or align it manually from the control panel.

Before you align the print head, note the following:

  • Alignment will vary based on the loaded media. Align the print head using the media on which you want to print and select the correct paper type as the Select Paper Type setting.
  • Run a nozzle check before you align the print head. If there are any gaps in the nozzle check pattern, clean the print head.
  • Automatic print head alignment cannot be performed on any transparent or colored paper or on these paper types: Plain paper, Epson Enhanced Matte Posterboard. Manually align from the printer control panel when using these media types.
  • Make sure the printer is not exposed to direct, bright light (such as direct sunlight) while performing an automatic print head alignment.

Aligning the Print Head Automatically Using the Product Control Panel

You can automatically align the print head using the control panel on your product.

  1. Load roll paper or cut sheet paper in this size or larger: A4 (8.3 × 11.7 inches [210 × 297 mm]).
  2. Make sure the correct paper type is selected.
  3. Press the Menu button.
  4. Press the up or down arrow button to select Maintenance and press the right arrow button.
  5. Select Head Alignment and press the right arrow button.
  6. Select Auto and press the right arrow button.
  7. Press the up or down arrow button to select one of the following options:
    1. Uni-D aligns each color for uni-directional printing based on Light Cyan.
    2. Bi-D 2-color aligns each color for bi-directional printing based on Light Cyan and Vivid Light Magenta.
    3. Bi-D All Color aligns each color for bi-directional printing based on all colors.
    4. Bi-D #1, Bi-D #2, Bi-D #3, and Bi-D #4 perform the most detailed adjustments based on the size of the ink dots. Run all four adjustments in order from Bi-D #1 to Bi-D #4 to ensure that the printer is aligned properly for all driver settings and ink dot sizes.
  8. Press the OK button.
  9. The alignment process starts.
    Note: Do not open the front cover or turn off the printer during the alignment process.
    When the automatic head alignment process is complete, your product should be properly aligned. If it is not, select a different alignment method and repeat the process. If your printer still is not properly aligned, perform a manual head alignment.

Aligning the Print Head Manually Using the Product Control Panel

   

  1. Load roll paper or cut sheet paper that is in this size or larger: A4 (8.3 × 11.7 inches [210 × 297 mm]).
  2. Make sure the correct paper type is selected.
  3. Press the Menu button.
  4. Press the up or down arrow button to select Maintenance and press the right arrow button.
  5. Select Head Alignment and press the right arrow button.
  6. Select Manual and press the right arrow button.
  7. Press the up or down arrow button to select one of the following options:
    1. Uni-D aligns each color for uni-directional printing based on Light Cyan.
    2. Bi-D 2-color aligns each color for bi-directional printing based on Light Cyan and Vivid Light Magenta.
    3. Bi-D All Color aligns each color for bi-directional printing based on all colors.
  8. Press the OK button.
  9. The alignment sheet prints.

    Note: When aligning on cut sheet paper, the alignment sheet it printed across multiple pages. Once the first sheet prints, load the next piece of paper.

  10. After each alignment sheet is printed, view the LCD screen for instructions on selecting the best square in each pattern set.
  11. Check the printed patterns and choose the number representing the pattern in which the white lines are the most evenly spaced, then press the OK button.
  12. When the manual head alignment process is complete, your product should be properly aligned. If it is not, select a different alignment method and repeat the process.
