Low paper sensing and calibration

Low-paper sensing in the Model 1NF is based upon the paper thickness and the core size. You can modify
the low-paper and critically low sensing settings. These settings determine the amount of paper that
remains on the roll and at which time the low-paper and the critically low-paper status is sent. The default
setting for low-paper status is 5 meters (or 5000 mm) remaining on the roll, and critically low status is 1
meter (or 1000 mm) remaining on the roll.
You must calibrate the printer to accurately recognize the thickness of the paper supply, which you can do
with an off-line test or by a command (see Table 13). You only need to calibrate one printer for a specific
paper supply. You can then broadcast that calibration constant to all printers that will use the same paper.
To set the low-paper supply sensors of all printers within your system:
1. Run the calibration on one printer (see Table 13).
2. Read out MCT#0X'28' from the calibrated printer.
Note: The calibration constant is stored in MCT#0X'28'. System management can interrogate all
printers to determine whether one has been recently calibrated.
3. Clear the high-order bit and send the value to all printers in the enterprise.

Provides information for service personnel.
You are instructed to insert a small roll of paper in the
printer. During the test the printer ejects all of the
paper from this roll to calibrate the low-paper sensor.
