1. Power button 2. Feed button 3. POWER indicator 4. DATA indicator 5. STATUS indicator 6. WIRELESS LAN indicator

[Case 1]  The DATA indicator remains lit in green, but the printer does not print.
 

• Printing of all received data is not completed. Wait until it is finished.
   
• If paper is not installed, load new paper.
   
• If the printer does not print even though paper is loaded, remove the paper, and then load it again.
   
• Try printing again after turning the printer off and then on again.

  If the printer is connected via wireless LAN, the connection is cut when the printer is turned off. When the printer is turned on again, it will take a maximum of about 15 seconds for wireless LAN to become functional.

• There may be problems with sending simple ASCII text data to the printer. If the CR/LF command is not at the end of lines or the form feed command is not at the end of the last line, the printer may be waiting for this data to be sent. Print another page, or press the Feed button to feed the paper.

[Case 2]  The computer program should be sending data to the printer, but the DATA indicator does light in green.
 

• With a USB connection:

   

  1. Make sure that the USB cable is connected firmly and properly.
      
  2. If the WIRELESS LAN indicator is lit or blinking, the printer is in wireless LAN mode. Switch the printer to USB mode.
      
  3. Try using another USB cable.

   

• With a wireless LAN connection:

   

  1. If the WIRELESS LAN indicator is turned off, the printer is in USB mode. Switch the printer to wireless LAN mode.
      
  2. Make sure that the wireless LAN settings have been specified properly.
