What card thickness is recommended for each unit and why?
For optimum printing quality we recommend that you use a 10mil to 33mil card in the PR5100. For the 5200, we recommend that you use nothing smaller then a 10mil card and nothing larger then a 50mil card. For the 5300, we recommend that you use nothing smaller then a 10mil card and nothing larger then a 45mil card. Reasons for the difference are: The 5100 was made with adjustable print block pinch rollers that can tighten to accept a 10mil card or loosened to accept a 33mil card. These rollers have springs on them, which only allow the rollers to spread apart so far limiting the size of the cards. NiSCA introduced the 5200 with the thicker card use market in mind. These print block rollers and pinch rollers automatically adjust for card thickness. Whether thick or thin this printer can handle it. The 5300 is set up exactly like the 5200 except that the rollers are limited in how far they will stretch and will accommodate up to a .045mil card.
