5.5.11 P_REAR Sensor Position Adjustment Menu
This menu is used to adjust the P_REAR sensor position for the detection of the correct cut sheet length..
In this adjustment, the P_REAR sensor position can be corrected in the firmware using nozzle print as a
reference, in order to maximize the printable area based on the end of media.
To adjust the margins, follow the steps below.
1. Set media as necessary.
NOTE
• For P_REAR sensor position adjustment, cut media is used. Set A3 or A4 cut sheet in the
longitudinal direction.
• P_REAR sensor position adjustment is required in the manufacturing process. Even if band feed
correction is performed, there is no need to perform this adjustment.
2. After media is set, the machine prints out P_REAR sensor position adjustment patterns as follows.
• Plot a horizontal line(black 1-dot line) for 17mm from the media end.
3. Measure the distance from the media end to the plotted line.
