1Under normal environmental conditions and on HP inkjet polyester D/A16size media, plot a drawing that contains two •X" marks nominally positioned 500 mm (19.69 in.) apart.
2Measure the distance between the centers of the •X" marks on the plot.
Accuracy calibration is needed if this distance is not 500 mm (19.69 in) 1 mm (0.04 in).
If the measured accuracy, media thickness, or environmental conditions vary greatly from the factory standards, recalibrate the plotter by continuing with the following procedure.
Performing the Accuracy Calibration on the DesignJet 230 and 250C1Read w Before Performing the Accuracy Calibration above.
2Place a sheet of HP inkjet polyester film over the top of the plotter for 10 minutes to let the sheet stabilize to the environmental conditions.
Use a sheet of approximate size A1 or D.
You must use polyester film. Otherwise the optical sensor on the carriage will be calibrated incorrectly, and the plotter will have problems loading some types of media.
3 In service mode 2, set the Media Type on the front panel to Film.
4Load the film, with the matte (dull) side down, in portrait orientation into the plotter.
5When the Ready LED lights up, hold down the
SHIFT key and press Accuracy Calib. Print.
The Ready LED begins to flash and the plotter plots a calibration plot. The plotter ejects the sheet, and the Load Media LED lights up.
6Unload the sheet.

7Cut the blank end off the film by cutting along the long dashed line on the plot; the cut must be very straight.
