There could be a number of reasons why your Lexmark T654 printer is taking to long to switch, or turn on. You may want to check the power cord to make sure that it isn't damaged anywhere. Also, check the outlet that it is plugged into. You very may well need to replace the power cord, or purchase a new printer. Lexmark can tell you if there is any known issues with your particular model, and if it is within the warranty period, you may get a replacement.
