OPERATOR PANELS
This chapter describes the function of the operator panel on your
printer. It is useful to describe the Status Monitor software at this
point as it provides the B4250, B4250n status information and the
equivalent of the menu control panel on the B4350, B4350n,
B4350nPS. (See “Printer Drivers” for installation of the Status
Monitor.)

B4250, B4250N
OPERATOR PANEL
The B4250, B4250n operator panel consists of 4 indicating LEDs 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:
lIndicator off
lIndicator on
lFlash 1 - slow blink - 1 long flash every 4 seconds
lFlash 2 - blink - 1 flash per second
lFlash 3 - rapid blink - 4 flashes per second.
All four LED indicators come on momentarily when power is switched
on using the main power switch.
