  The message Cooling appears on the LCD.

  Wait until the message disappears and then try printing again.

• Are there any unfinished print jobs?

  If you try to print while other users are printing large amounts of data, the printer is unable to accept your print job until the current print jobs are completed. If this occurs, send the print job again after the other jobs are completed.

• Head:

  If the print head becomes too hot, it may produce imaging on the paper in areas not intended to be printed. This condition is normal when printing documents with a lot of “black” content.

  The printer will stop and resume printing after the print head has cooled down.

  To avoid or delay this condition, print using a lighter density setting, reduce the amount of black space being printed (for example, remove background shading and colors in graphs and presentation documents), and make sure that the printer has adequate ventilation and is not located in an enclosed space.

• Motor or battery:

  Do not use the printer continuously. If the printer is used continuously, the motor or battery will become too hot. In this case, the printer will stop and resume printing after the motor or battery has cooled down.
