HP Designjet 4000 Printer Series - User Guide

3. When you have inserted the printhead cleaner(s) into the printer, close the door.
Note The printer needs all the ink cartridges, printheads, and printhead
cleaners to be installed before it can continue.
4. If no paper is loaded, the front panel will instruct you to load some.
Whenever you insert a new printhead and cleaner, the printer will normally perform a
printhead alignment and color calibration. Both are recommended for best print
quality. In some cases, you may decide to postpone printhead alignment until after
some further printing has been done.
Note If you prefer to save some time at the expense of print quality, you can
turn off these automatic procedures from the front panel, by selecting the
icon, then Configuration menu > Auto. printhead alignment > Off and
Configuration menu > Color calibration > Off.
The front panel may request that you load paper that is suitable for printhead
alignment. The printhead alignment procedure requires a roll of opaque paper: not a
single sheet, and not any kind of transparent or translucent material.
When the front panel displays Ready, you are ready to print.
Note Make sure the printer window and the right-hand door are closed after
you replace the supplies. The printer will not print while these are open.
