is the printer fusing temperature.
CAUTION
To avoid damage to the printer, use only transparencies that are recommended for use in
laser printers. See

Resolving the control panel messages.
ENWWControl panel features23
 
						

							Understanding Supplies Status
The printer contains five lights and one button to indicate and control the status of the print
cartridges and imaging drum. To interpret and troubleshoot control panel light messages,
see 
Resolving the control panel messages.
Black, Cyan, Magenta, and Yellow Supplies Status lights
These lights indicate when a print cartridge is low (the light is on), or empty or missing (the
light blinks). The lights also indicate when a non-HP print cartridge is installed (the light
blinks and the Attention light is on).
Rotate Carousel button
When the top cover is closed, pressing  (ROTATE CAROUSEL) rotates the print-cartridge
carousel to bring the next print cartridge into the top position. The light for the print cartridge
that is approaching the top position blinks quickly two or three times.
Imaging drum light
This light indicates when the imaging drum is low (light is on), or empty or missing (light
blinks). The light also indicates when a non-HP imaging drum is installed (the light blinks and
the Attention light is on).
Understanding Printer Status
The printer has two buttons and three lights to indicate and control the printer status. To
interpret and troubleshoot the control panel light messages, see 
Resolving the control panel
messages.
Cancel Job button
●
When the Ready light is blinking, pressing  (CANCEL JOB) cancels the current job.
●
When the printer is not experiencing an error, pressing 
 (GO) and  (CANCEL JOB)
simultaneously prints a Configuration page and a Supplies Status page. (If an HP
Jetdirect print server is installed, an HP Jetdirect page also prints.)
●When a Supplies Status light is blinking and the Attention light is on (indicating that a
non-HP supply has been installed), pressing 
 (CANCEL JOB) allows you to continue
printing.
CAUTION
You might not receive any indication when a non-HP supply is empty. If you continue
printing after the supply is empty, damage to the printer can occur. See 
Hewlett-Packard
limited warranty statement.
Attention light
Generally, the Attention light blinks when the printer is out of paper, when a jam has
occurred, or when other problems that need attention occur.
The Attention light is on and one of the Supplies Status lights is blinking the first time a non-
HP supply is installed.
24Chapter 2 Control panelENWW
 
						

							Ready light
The Ready light is on when the printer is ready to print (experiencing no errors that prevent
printing) and blinks when it is receiving data to be printed.
Go light and Go button
●
When the Go light is on and the Attention light is blinking, pressing  (GO) continues
the print job after you load print media for a manual feed, or clears some errors.
●When the Go light is blinking, the top cover has been opened and then closed or you
have pressed 
 (ROTATE CAROUSEL). Pressing  (GO) returns the printer to the Ready
state. If you do not press 
 (GO), the printer returns to the Ready state on its own.
●
When the Go light is off, pressing 
 (GO) prints a Demo page. Pressing  (GO) and
 (CANCEL JOB) simultaneously prints a Configuration page and a Supplies Status page.
(If an HP Jetdirect print server is installed, an HP Jetdirect page also prints.)

							Loading trays
Load special print media, such as envelopes, labels, and transparencies, in tray 1 only. Load
only paper in optional tray 2 or optional tray 3.
Note
Because tray 2 and tray 3 are not included for all models, they are referred to as optional
tray 2 and optional tray 3 in this documentation.
Loading tray 1
Tray 1 (the multipurpose tray) holds up to 125 sheets of paper or other print media, or it
holds up to 10 envelopes.
For information about loading special print media such as labels and transparencies, see
Printing on special media.
CAUTION
Avoid adding print media to tray 1 while the printer is printing, or jams can occur. Do not fan
paper before loading it into trays, and avoid overloading trays.
To load tray 1
1. Open tray 1.
2. Slide out the tray extender. If the print media being loaded is longer than 23 cm (9
inches), also open the additional tray extender.
3. Slide the media-width guides slightly wider than the print media.
28Chapter 3 Printing tasksENWW
 
						

							4. Place print media into the tray with the side to be printed up, and the top, short edge in
first.
NoteIf you are manually duplexing, see Printing on both sides (duplexing manually) for loading
instructions.
5. Slide the media-width guides inward until they lightly touch the print media stack on both
sides without bending it. Make sure that the print media fits under the tabs on the media-
width guides.
CAUTIONWait for the printer to finish printing before closing tray 1. Closing the tray before the printer
finishes can cause jams.
6. On the back of the printer, lower the rear output door if you are printing on special
media, such as labels, envelopes, or heavy or light paper, to prevent curl.
Loading optional tray 2
Paper includes average-weight letterhead and prepunched paper. For additional information
about letterhead and prepunched paper, see 
Printing on letterhead or preprinted forms.
CAUTION
Print on special print media such as labels and transparencies from tray 1 only. Printing on
special print media from optional tray 2 or optional tray 3 can cause jams. Do not fan paper
before loading it into trays, and avoid overloading trays.
ENWWLoading trays29
 
						

							To load optional tray 2
1. Pull optional tray 2 out of the printer and remove any paper.
2. Move the media-width guides to match the size of paper that you are loading. Tray 2
accepts several standard paper sizes.
3. Extend the rear of the tray until the arrow on the markings points to the size that you are
loading.
4. Load the paper. If this is special paper such as letterhead, load it with the side to be
printed on facing down and the top edge toward the front of the tray.
NoteIf you are duplexing manually, see Printing on both sides (duplexing manually) for loading
instructions.
