The best way to maintain peak performance from your PrismJet 48 or VJ-1204 54" printer is to print daily. At a minimum, you must print at least every week. Not printing every week can void your warranty and cause extensive damage to your printer which is costly to repair. For this reason, it is essential that owner/operators take proper longstore precautions before allowing the printer to rest for over a week.
