HP LaserJet 4250 User Manual

							Loading staples
Load staples if the printer control-panel display prompts you with a STAPLER LOW ON
STAPLES  message (the stapler has fewer  than 70 staples left) or a STAPLER OUT OF
STAPLES  message (the stapler is empty). If the  stapler runs out of staples, jobs continue to
print to the stapler/stacker, but they are not stapled.
To load staples
1. On the right side of the stapler/stacker, turn  the stapler unit toward the front of the printer
until the unit clicks into the open  position. Grasp the blue staple-cartridge handle and
pull the cartridge out of the stapler unit.
2. Insert the new staple cartridge into the stapler  unit and rotate the stapler unit toward the
rear of the printer until the unit snaps into place.

							Loading trays
This section describes how to load the standard and optional printer trays.
Loading tray 1 
Tray 1 is a multipurpose tray that holds up to 100 sheets of paper, 50 transparencies or
sheets of labels, 10 envelopes, or 20 index cards. The printer default is to pull media from
tray 1 first, if it is loaded. To change this behavior, see 
Customizing tray 1 operation .
Tray 1 provides a convenient way to  print on envelopes, transparencies, custom-size paper,
or other types of media without having to unload the  other trays. It can also be used just as a
convenient additional tray. For supported media sizes, see 
Supported sizes of print media .
If an optional stapler/stacker is installed, the printer automatically rotates the printed images
180° on all media sizes, even if the job is  not stapled. If you are printing on paper that
requires a specific orientation, such as letterhead, preprinted paper, prepunched paper, and
paper with watermarks, make sure that the paper is loaded correctly in the tray. See
Orientation of paper when a stapler is installed .
NOTE
The printer might print at a slower speed when using tray 1.
CAUTION
To avoid jams, do not load trays while the  printer is printing. Do not fan the paper. Fanning
can cause misfeeds.
To load tray 1
1. Open tray 1.
2. Pull out the tray extension.

							3. Set the side guides to the correct width.
4. Load the media in the tray. Make sure that the media fits under the tabs and below the
maximum-height indicators.
NOTELoad media with the front side facing up and the top, short edge toward the printer. For
information about loading special media, see 
Printing on small sizes, custom sizes, or heavy
paper .
5. Adjust the side guides so that they lightly touch the media stack but do not bend the media.
Loading tray 2 or an optional 500-sheet tray
The 500-sheet tray adjusts for six standard sizes (letter, A4, legal, executive, A5, and B5
JIS), and for many custom sizes. See 
Supported sizes of print media . The printer senses
standard sizes if you set the tray guides to  a standard size and turn the media knob to
Standard.
If an optional stapler/stacker is installed, the printer automatically rotates the printed images
180° on all media sizes, even if the job is not stapled. If you are printing on media that
requires a specific orientation, such as letterhead, preprinted media, prepunched media, and
media with watermarks, make sure that the media  is loaded correctly in the tray. See
Orientation of paper when a stapler is installed.
CAUTION
To avoid jams, do not load trays while the printer is printing.

							To load tray 2 or an optional 500-sheet tray
1. Pull the tray out and lift up slightly to remove it from the printer.
2. Pinch the release that is located on the left guide and slide the side guides to the correct
paper size.
3. Pinch the release that is located on the rear  paper guide and slide it to the correct media
size.
4. On the right side of the tray, turn the knob to Standard for LTR (letter), A4, LGL (legal), EXEC (executive), A5, or JIS B5 paper. Turn  the knob to Custom for supported custom
paper sizes.

							5. Load the paper with the front side facing down and the top edge toward the front of the
tray.
CAUTIONDo not fan the paper. Fanning can cause misfeeds.
6. Make sure that the stack is flat at all four corners and that the top of the stack is below the maximum-height indicators.
7. Slide the tray completely into the printer.
Loading an optional 1,500-sheet tray
The optional 1,500 sheet tray adjusts for letter,  A4, and legal sizes. The printer automatically
senses which size is loaded if the tray guides are properly adjusted.
If an optional stapler/stacker is installed, the printer automatically rotates the printed images
180° on all paper sizes, even if the job is  not stapled. If you are printing on media that
requires a specific orientation, such as letterhead, preprinted media, prepunched media, and
media with watermarks, make sure that the media  is loaded correctly in the tray. (See
Orientation of paper when a stapler is installed.)
CAUTION
To avoid jams, do not load trays while the printer is printing.
ENWW Loading trays53
 
						

							To load an optional 1,500-sheet tray
1. Open the door of the 1,500-sheet tray.
2. If media is in the tray, remove it. When media is in the tray, the guides cannot be
adjusted.
3. Pinch the guides at the front of the tray and slide them to the correct media size.
4. Load the media with the front side facing down  and the top edge toward the front of the
tray.
CAUTIONDo not fan the media. Fanning can cause misfeeds.

							Understanding media output options 
The printer has three output locations: the top (standard) output bin,\
 the rear output bin, and
the optional stacker or stapler/stacker.
Printing to the top (standard) output bin
Printing to the rear output bin
Printing to the optional stacker or stapler/stacker
Orientation of paper when a stapler is installed
Printing to the top (standard) output bin
The top output bin collects paper face-down, in the correct order. The top output bin should
be used for most print jobs, including transparencies. To use the top output bin, be sure that
the rear output bin is closed.  To avoid jams, do not open or  close the rear output bin while
the printer is printing.
Printing to the rear output bin
The printer always prints to the rear  output bin if it is open. Media that is printed to this bin
will exit face-up, with the  last page on top (reverse order).
Printing from tray 1 to the rear output bin  provides the straightest path. Opening the rear
output bin might improve performance with the following items:
● Envelopes
● Labels
● Small custom-size paper
● Postcards
● Paper heavier than 120 g/m
2 (32 lb)

							To open the rear output bin, grasp the handle at the top of the bin. Pull the bin down, and
slide out the extension.
Opening the rear output bin makes the duplexer (if installed) and the top output bin
unavailable. To avoid jams, do not open or close  the rear output bin while the printer is
printing.
Printing to the optional stacker or stapler/stacker
The optional stacker or optional stapler/stacker can  hold up to 500 sheets of paper (20-lb
paper). The stacker accepts standard and custom paper sizes. The stapler/stacker accepts
standard and custom paper sizes, but only letter, legal,  and A4 sizes can be stapled. Do not
try to send other types of print media, such as labels or envelopes.
When a stapler/stacker is installed, the printer automatically rotates the printed images 180°
on all paper sizes, regardless of whether the job is stapled. Paper types that must be printed
in the correct orientation, such as letterhead  or prepunched paper, might need to be loaded
in a different direction. See 
Orientation of paper when a stapler is installed .
To print to the optional stacker or optional stapler/stacker, select the option in the program,
in the printer driver, or at the printer control panel.
Before you use the optional stacker or optional stapler/stacker, ensure that the printer driver
is set to recognize it. You need to set  this setting only once. See the printer driver online
Help for details.
