Hi there, Recently i changed my Plotter Timing Belt along with its Pulley( Left Side one ) but my engineer put Plain Pulley with up-down guider for belt to move L/R. When we started the plotter we realised that the centre Pinch Roller when placed at distance of 24" and upto till second last one the plotter gives the ERROR S05 ( MEDIA NOT DETECTED ), its really Weard. Could anyone of you'l help me in Solving this problem. Please Help.
