The printer's rear lights
At the rear of the printer, above the power switch, are three small lights:
● The amber light on the left is on when the printer is in sleep mode.
● The blue light in the center is on when the printer is on (when it has electrical power).
● The green light on the right is on when the printer is printing.
NOTE: You should never see all three lights on at the same time, because the printer cannot print in
sleep mode.
The printer's internal prints
The internal prints give various kinds of information about your printer. They can be requested from the
front panel without using a computer.
Before requesting any internal print, make sure that paper is loaded (roll or sheet), and that the front
panel displays the Ready message. The paper should be at least 36 in (91.44 cm) wide, otherwise the
print may be clipped (HP Designjet 4020 series) or put “on hold for paper” (HP Designjet 4520 series).
To print any internal print, select the icon, then Internal prints, then select whichever internal print
you want.
The following internal prints are available:
● Demo: shows some of the capabilities of the printer.
● Menu map: shows details of all the front panel menus.
● Configuration: shows all the current front panel settings.
● Usage report: shows estimates of the total number of prints, number of prints by paper type, number
of prints by print quality option and total amount of ink used per color. The accuracy of these
estimates is not guaranteed.
