Canon BJ Printer Driver Version 1.07 for AutoCad R12 To correct for the paper feed slippage apparent with the 3X0 printers the printer driver may be calibrated. Note that the paper motion is in the X direction (ie the Y direction should not need calibrating). The slippage is dependent on the paper width (and type) so you may need to set up several copies of the driver for different widths. After calibration you will still see slight jaggies where the print head bands overlap, but the overall length will be better. The instructions on page 43 & 44 of the Installation manual may be used to calibrate the plotter, but you will have to re- answer the plotter specific questions (including the plotter model) first to get to the "generic" questions that allow you to enter the calibration factors (simply use the defaults for the plotter questions). The installation manual says that the calibration may be cancelled by entering the same plotter name after saying that you want to choose a new one, note that this is also within the Change Plotter sub-menu. Show Device Requirements will say "calibrated" on the line which displays the resolution if this has been done.
