HP LaserJet M1120 User Manual

							Embedded Web server (network models only)
Network models are equipped with an embedded Web server (EWS), which provides access to
information about product 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 a 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 HP LaserJet product) 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 product that anyone with a network-
connected product and computer can use. There is no special software to install or configure, but you
must have a supported Web browser on the computer. To gain access to the EWS, type the IP address
for the product in the address line of the browser. (To find the IP address, print a configuration page.)
Features
The EWS allows you to view product and network status and manage printing functions from a computer.
With the EWS, you can complete the following tasks:
●View product status information
●Determine the remaining life on all supplies and order new ones
●View and change part of the product configuration
●View and print some internal pages
●Select the language in which to display the EWS pages
●View and change network configuration
NOTE:Changing network settings in the EWS might disable some of product software or features.
Security features
Secure the embedded Web server
On network models, use the EWS to set a password.
1.Open the EWS, and then click the System tab.
2.Click Password.
3.In the Password box, type the password you want to set, and then in the Confirm password box,
type the same password again to confirm your choice.
4.Click Apply to save the password.

							Manage supplies
Check and order supplies
You can check the supplies status by using the product control panel. Hewlett-Packard recommends
that you place an order for a replacement print cartridge when Low message for a print cartridge first
appears. Use a new, authentic HP print cartridge to obtain the following types of supplies information:
●Amount of cartridge life remaining
●Estimated number of pages remaining
●Number of pages printed
●Other supplies information
If the supplies levels are low, you can order supplies through a local HP dealer, by telephone, or online.
Go to 
www.hp.com/go/ljsupplies to order online.
Store supplies
Follow these guidelines for storing print cartridges:
●Do not remove the print cartridge from its package until you are ready to use it.
CAUTION:To prevent damage, do not expose the print cartridge to light for more than a few
minutes.
●Store print cartridges within storage temperature ranges of -20° to 40° C (-4 to 104° F).
●Store the supply in a horizontal position.
●Store the supply in a dark, dry location away from heat and magnetic sources.
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.
HP fraud hotline
Call the HP fraud hotline if the product 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.
The print cartridge might not be a genuine HP one if you notice the following issues:
●You are experiencing a large number of problems with the print cartridge.
●The print cartridge does not look like it usually does (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,
72 Chapter 10   Manage and maintain the product ENWW
 
						

							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.
Recycle 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.
Redistribute toner
If faded or light areas appear on the printed page, you might be able to temporarily improve print quality
by redistributing the toner.
1.Remove the print cartridge from the printer.
2.To redistribute the toner, gently rock the print cartridge from front to back.
CAUTION:If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold
water. Hot water sets toner into the fabric.
3.Reinsert the print cartridge into the printer, and close the print cartridge door. If the print is still light
or unacceptable, install a new print cartridge.

							Control-panel messages
The majority of the control-panel messages are intended to guide the user through typical operation.
The control-panel messages indicate the status of the current operation, and include a page count on
the second line of the display, if appropriate. When the product is receiving print data or scanning
commands, control-panel messages indicate this status. In addition, alert messages, warning
messages, and critical error messages indicate situations that might require some action.
Alert and warning messages 
Alert and warning messages appear temporarily and might require the user to acknowledge the
message by pressing OK to resume or by pressing Cancel to cancel the job. With certain warnings, the
job might not complete or the print quality might be affected. If the alert or warning message is related
to printing and the auto-continue feature is on, the product will attempt to resume the printing job after
the warning has appeared for 10 seconds without acknowledgement.
