5.11.1.1 Receipt Paper-error Sensor
The paper-error sensor in the Series 90PLUS Printer monitors the diameter of the paper roll to
determine how much paper is left. The sensor will report paper low to the software when a 1.27-inch
roll diameter is reached. The amount of paper left on the roll depends on the type of paper being used.
The following table specifies the amount of paper on the roll when paper low is sensed.
Type of paper Amount of Paper Left
Single-ply
16 feet ± 8 feet (487 cm ± 244 cm)
Double-ply
8 feet
±
4 feet (244 cm

122 cm)
Triple-ply

There are four ways that the sensor can operate. The first is hard-fault mode. In hard-fault mode when
paper low is detected, the printer goes off-line and stops. (To select this option, choose Mode 1 with 0
feet). The second is soft-fault mode. With soft-fault mode when the printer detects paper low, an error
is visually displayed to the operator. The printer will continue to print the number of lines specified by
the paper error command. (To select this option, choose Mode 2 with 1 to 15 feet). When paper-low
status is detected in the third method, the printer continues to print for a specified length of paper and
faults with no operator warning. (To select this option, choose Mode 1 with 1 to 15 feet). In the fourth
method, the paper-low signal is completely ignored, and the printer will print with no paper

or error
fault. (To select this option, choose Mode 0 with 0 feet).
When the printer generates a paper out fault, the printer stops printing. Because the paper out fault is
calculated, the printer may not be completely out of paper. By pushing the RESUME key, the printer
will add four inches to the paper out length. This can be done as long as the cover is not opened. It is
possible, however, to print past the end of the receipt roll by continually pushing the RESUME key.

This mode should not be selected unless the receipt station is not to be used. In other words, it must be a
validation only printer.
Note: in disabled mode, the [ENQ] command for receipt paper status will not operate. It will always return “paper
present.”
