Well my Mutoh Falcon Jr outputs very good quality prints at 720 bi-direction and outstanding prints at 720 high quality. If you are not printing everyday, run a nozzle check or make a small CYMK test file to print so the printhead stay open. You can perform "head cleanings and powerful head cleanings" if needed. Cleaning the cap station, around the print heads and watching your waste lines and make sure everything is moving are basic part of maintenance. Maintenance manuals are available in PDF form and are free. Parts are available and replacing them are only part of maintenance. Look at it like the tires wear out on your car and need to be replaced. There have been a lot of post here about printer maintenance that is available. If you need anything, I am always glad to share what I know or have found out. The Falcon is a good printer and with a cutter for contour cutting, you will find you have a very efficient work system. Check out the "looking at print/cut?"link on the bottom, signmythbreakers.com for real life speed and work flow information.
Nice going and good luck.
