CX400 Technical Manual (Rev 1.00) Or you are also able to directly send out a group of commands to printer for calibrating the media sensors in either Imark(Reflective )or Gap(See-Through ) mode. Two groups of commands for Bar & Gap mode sensor are listed below, A CI1 CA Z < In Gap mode > A CI2 CA Z 3. Once the Media sensor calibration is activated in step 2, the printer will feed several labels ( 6 inches) to perform this calibration.
PAGE 13
CX400 Technical Manual (Rev 1.00) 5.2.2 Calibration for Ribbon Sensor The calibration for Ribbon sensor might need to be performed while the particular Ribbon & Media you installed makes this printer fails to detect ribbon out or the end of ribbon. Actually it is not necessary to perform this calibration except the installed Ribbon & Media are very particular. The calibration for ribbon sensor is used for the printer to keep the characteristics of ribbon sensor, ribbon and media.
