HP LaserJet 3050z User Manual

							Embedded Web server
This all-in-one is equipped with an embedded Web server (EWS), which provides access to
information about all-in-one and network activities. A Web server provides an environment in which
web programs may run, much in the same way that an operating system, such as Windows, provides
an environment for programs to run on your computer.  The output from these programs can then be
displayed by a Web browser, such as Microsoft Internet Explorer, Safari, or Netscape Navigator.
An “embedded” Web server resides on a hardware device (such as an all-in-one) or in firmware,
rather than as software that is loaded on a network server.
The advantage of an EWS is that it provides an interface to the all-in-one that anyone with a network-
connected all-in-one and computer can use. There is no special software to install or configure, but
you must have a supported Web browser on your computer. To gain access t\
o the EWS, type the IP
address for the all-in-one in the address line of  the browser. (To find the IP address, print a
Configuration page. For more information about printing a Configuration page, see 
Configuration
page .)
NOTE For Macintosh operating systems, you can use the EWS over a USB connection after
installing the Macintosh software included with the all-in-one.
Features
The EWS allows you to view all-in-one and network status and manage printing functions from your
computer. With the EWS, you can complete the following tasks:
● View all-in-one status information
● Determine the remaining life on all supplies and order new ones
● View and change part of the all-in-one configuration
● View and print some internal pages
● select the Language in which to display the EWS pages
● View and change network configuration

							Managing supplies
Checking status and ordering supplies (HP LaserJet 3390/3392 all-
in-one only)
You can check the supplies status by using the all-in-one control panel, printing a Supplies Status
page, or viewing the HP ToolboxFX. Hewlett-Packard recommends that you place an order for a
replacement print cartridge when you first receive the  Low message for a print cartridge. When you
use a new, authentic HP print cartridge, you can obtain the following types of supplies information:
● Amount of cartridge life remaining
● Estimated number of pages remaining
● Number of pages printed
● Other supplies information
NOTE
If the all-in-one is connected to the network, you can set the HP ToolboxFX to notify
you by e-mail when a print cartridge is low. If the all-in-one is directly connected to a
computer, you can set HP ToolboxFX to notify you when supplies are low.
To check supplies status by using the control panel
Do one of the following:
● Check the all-in-one control panel, which indicates when a print cartridge is low or empty. The
control panel also indicates when a non-HP print cartridge is first installed. See 
Troubleshooting
tools
 for more information.
● Print a Supplies Status page, and then check 
the supplies levels on the page. See 
Supplies
Status page (HP LaserJet 3390/3392 all-in-one) for more information.
If the supplies levels are low, you can order supplies through your local HP dealer, by telephone, or
online. See 
Accessories and ordering information  for part numbers. See www.hp.com/go/ljsupplies  to
order online.
To check supplies status by using HP ToolboxFX
You can configure HP ToolboxFX to notify you when the supplies are low. You can choose to receive
alerts by e-mail or as a pop-up message or taskbar icon.

							Storing supplies
Follow these guidelines for storing print cartridges:
●Do not remove the print cartridge
 from its package until you are ready to use it.
CAUTIONTo prevent damage, do not expose the print cartridge to light for more than a
few minutes.
● See Environmental specifications for operating and storage temperature ranges.
● Store the supply in a horizontal position.
● Store the supply in a dark, dry location away from heat and magnetic sources.
Replacing and recycling supplies
To install a new HP print cartridge, follow the instructions  that are included in the box that contains
the new supply, or see the getting started guide.
To recycle supplies, place the used supply in the box in which the new supply arrived. Use the
enclosed return label to send the used supply to HP for recycling. For complete information, see \
the
recycling guide that is included with each new HP supply item. See 
HP LaserJet printing supplies  for
more information about HPs recycling program.
HP policy on non-HP supplies
Hewlett-Packard Company cannot recommend the use  of non-HP supplies, either new or
remanufactured. Because they are not HP products, HP  cannot influence their design or control their
quality. Service or repairs required as a  result of using a non-HP supply will not be covered under the
warranty.
When you insert a supply into the all-in-one, the all-in-one will inform you if the supply is not a
genuine HP supply. If you insert a genuine HP supply  that has reached the low state from another
HP device, the all-in-one identifies the supply as  non-HP. Simply return the supply to the original
device to reactivate the HP features and functionality.
Resetting the all-in-one for non-HP supplies (HP LaserJet 3390/3392 all-in-one)
When you install a non-HP print cartridge,  Unauthorized appears on the control-panel display. In
order to print with this supply, you must press 
 the first time you install this non-HP supply.
CAUTION The all-in-one will not stop printing when this  type of supply is empty. Damage to
the all-in-one could occur if the all-in-one prints with an empty non-HP print cartridge. See
Hewlett-Packard limited warranty statement  and Print Cartridge Limited Warranty Statement .
HP fraud hotline
Call the HP fraud hotline if the all-in-one or HP  ToolboxFX indicates that the print cartridge is not an
HP print cartridge and you think that it is genuine.  HP will help determine if the product is genuine
and take steps to resolve the problem.
ENWW Managing supplies 285
 
						

							Your print cartridge might not be a genuine HP one if you notice the following issues:

 (for example, the pull tab or the box is
different).
In the United States , call toll-free: 1-877-219-3183.
Outside the United States , you can call collect. Dial the operator and ask to place a collect call to this
telephone number: 1-770-263-4745. If you do not  speak English, a representative at the HP fraud
hotline who speaks your language will assist you. Or,  if someone who speaks your language is not
available, a language line interpreter will connect approximately  one minute after the beginning of the
call. The language line interpreter is a service that will translate between you and the representative
for the HP fraud hotline.
