The machine itself requires no maintenance. There are two consumable items with the iMARK Die Cutter—the cutting plastic and multi-purpose carrier tray. Replacement cost of the cutting plastic is relatively inexpensive, at pennies per wallet photo or business card. Three sheets of cutting plastic come with the system, and we recommend the plastic be replaced every 100 cuts, 50 cuts per side. The tray should be replaced if the metal shows signs of stretching (generally caused by using single format dies one at a time).
