The image file size may be larger than usual, often a large PostScript file, and may therefore take longer to process. Wait a few minutes for the printer to finish processing the file. The printer is too warm. Turn Off the printer for ten minutes to let it cool down. Consider moving the printer to a location where the temperature is lower.
