OPERATOR PANELS

This chapter describes the function of the operator panels. It is useful to

describe the Status Monitor software at this point as it provides the B4100

and B4250 status information and the equivalent of the menu control

panel on the B4350 and B4350n. (See “Printer Drivers” for installation of

the Status Monitor.)

B4100, B4250

OPERATOR PANEL

The B4100 and B4250 operator panel consists of 4 LED indicators and a

control button. From left to right, the LEDs indicate Power On, Ready,

Manual feed and Error.

LED INDICATORS

The LED indicators show the status of the printer and have five operating

conditions as follows:

> Indicator off

> Indicator on

> Flash 1 - slow blink - 1 long flash every 4 seconds

> Flash 2 - blink - 1 flash per second

> Flash 3 - rapid blink - 4 flashes per second.

All four LED indicators come on momentarily when power is turned on.

Power on LED (green)

This indicator comes on and stays on when the printer is turned on.

Ready LED (green)

> Indicator on - the printer is on-line and ready to receive data.

> Indicator off - the printer is off-line and cannot receive data.

page overflow, or receiving buffer overflow.

> Interrupting data processing when the printer is receiving and

processing data.

> Resuming data processing.

The secondary functions of the control button are activated after turning

the printer off line, then pressing and holding the switch for at least two
