Clean The Print Head Nozzles

The following contains instructions to check the nozzles for poor print quality and perform cleanings of the print head nozzles as necessary. If print results are faint or streaks are printed, the print head nozzles may be clogged. Those phenomena can be improved by performing print head cleanings or print head deep cleanings.

Print Nozzle Check Pattern

1. Open the paper output tray.
   (Confirm that the paper thickness lever is set to the left.)
   
   
2. Load letter-sized plain paper in the auto sheet feeder (ASF).
   
   
3. Press the <Menu> button.
   
   
4. Press the left or right cursor to select [Maintenance/settings], then press <OK>.
   
   
5. Press the left or right cursor to select [Maintenance], then press <OK>.
   
   
6. Press the up or down cursor to select [Nozzle check], then press the <OK>.
   
   
   
   
7. Press the up or down cursor to select [Yes], then press <OK>. (The nozzle check pattern is printed.)
   
   
8. Confirm the nozzle check pattern.

Note:

• When all patterns are printed normally, press the up / down cursor button to select "All A" and press the OK button.
• When any pattern is printed abnormally, press the up / down cursor button to select "Also B" and press the OK button.

Deep Print Head Cleaning

1. Press the <Menu> button.

6. Print the nozzle check pattern and check the print head status.

Note:

If the printed result dose not improve even after doing print head deep cleaning, turn off the printer. Then, after 24 hours or later, do print head deep cleaning again. After a given time interval, ink could dissolve itself, resulting in ink unclogging. When the printed result does not improve even after these steps, replacement of ink cartridges may be required.
