1. A method for adapting a conventional printer to print on a silica-based medium, the conventional printer being adapted to print images transmitted from a computer and having a fixing unit for bonding a toner to a cellulose-based print medium;

  • the bonding being at least partially accomplished using a top fuser roller and a bottom fuser roller where each of the top fuser roller and the bottom fuser roller enclose a top heating element and a bottom heating element, respectively, and the top fuser roller and the bottom fuser roller each having a roller body elongated about a central axis and having a first liner covering the roller body;

    the fixing unit further having an oil depositing assembly for depositing oil with an oil roller onto the top fuser roller for a fixed duration prior to receipt of the cellulose-based print medium by the fixing unit and having a retraction system for withdrawing the oil roller from the top fuser roller after the fixed duration;

    said method comprising a step of disabling the bottom heating element in the bottom fuser roller thus discontinue thermal radiation from the bottom heating element and decreasing heat propagation to a bottom portion of the silica-based medium.
