Xerox 96 NPS manual Fault masking

2.	Fault masking

This chapter describes the behavior of the 96/4635/180 NPS while printing with fault conditions in existence.

The DocuPrint 96, 4635, and 180 NPS enable you to continue printing while certain faults or conditions exist in parts of the printer not currently in use. Such faults or conditions are said to be masked. If, for example, you are printing a job using feeder tray 1 and stacker bin A, the printer continues printing even if feeder tray 2 is jammed or if stacker bin B is full.

When there is a masked fault or condition, the Hint icon (a light yellow circle with an asterisk inside) appears on the printer console and the Attention light goes on. A message, preceded by an asterisk, also appears in line 3 of the message area of the printer console. To display the area containing the masked fault (for example, the location of the paper jam), touch the Fault List icon (shown below) on the printer console to display the Fault List screen.
