Cleaning the printer
Cleaning the engine
During the printing process, paper, toner, and dust particles can accumulate inside the printer. 
Over time, this buildup can cause print-quality problems such as toner specks or smearing. Use 
a cleaning page to correct and prevent these types of problems. 
Figure 8. Toner specks and smearing
To use a cleaning page
Note The following procedure must be performed from the HP Color LaserJet 2500 Series Toolbox, 
which is supported for Windows 98, NT 4.0, Me, 2000, and XP. To clean the engine when the 
computer is running a different supported operating system, see the Readme on the software 
CD-ROM, or visit http://www.hp.com/support/clj2500.
1 Make sure the printer is turned on and in the Ready state.
2 Open the HP Color LaserJet 2500 Series Toolbox.
3 On the  Troubleshooting tab, click  Cleaning Page and click Print. A page with a pattern 
prints from the printer.
4 At the printer, remove any media from tray 1 (multipurpose tray).
5 Remove the page that printed and load it face-down into tray 1 (see figure 9).

Calibrating the printer
The printer automatically performs a calibration when the imaging drum or a print cartridge is 
changed, and at set intervals determined by the total number of pages the printer has printed. 
You can change the interval at which the printer performs automatic calibrations by using the 
embedded Web server.
You can also calibrate the printer manually when you clean the density sensor or when you 
experience color-related issues.
To calibrate the printer manually
Turn the printer off, wait one minute, and then turn the printer on again.
To calibrate the printer from the HP Color LaserJet 2500 Series Toolbox
NoteThe following procedure must be performed from the HP Color LaserJet 2500 Series Toolbox, 
which is only supported for Windows 98, NT 4.0, Me, 2000, and XP. To clean the engine when 
the computer is running a different supported operating system, see the Readme file on the 
software CD-ROM, or visit  http://www.hp.com/support/clj2500.

Managing supplies
For warranty information about these supplies, see  “Limited warranty for the print cartridge and 
drum”  on page 24.
Supplies life 
The life of the imaging drum depends on the number of black-only or color pages that print jobs 
require. An HP Color LaserJet 2500 series imaging drum lasts an average of 20,000 pages when 
printing black-only pages and 5,000 pages when printing color pages. Actual life lies somewhere 
between these two numbers, depending on the number of black-only pages you print versus 
color. The average life is between 6,000 and 8,000 pages.
The life of a print cartridge depends on the amount of toner that print jobs require. When printing 
text at five-percent coverage, an HP Color LaserJet 2500 series cyan, magenta, or yellow print 
cartridge lasts an average of 4,000 pages, and a black print cartridge lasts an average of 5,000 
pages.
Checking and ordering supplies 
You can check the supplies status by using the printer control panel, printing a Supplies Status 
page, viewing the embedded Web server, viewing Printer Status and Alerts, or viewing 
HP Web Jetadmin. Hewlett-Packard recommends that you place an order for a replacement print 
cartridge when you first receive the Low message for a print cartridge. The Low message 
indicates that approximately two weeks of life remain. When you use a new, authentic HP print 
cartridge or imaging drum, you can obtain the following types of supplies information:

amount of cartridge or drum life remaining

estimated number of pages that can be printed

number of pages printed

other supplies information
Note If the printer is connected to the network, you can set the embedded Web server to notify you by 
e-mail when a print cartridge or the imaging drum is low. If the printer is directly connected to a 
computer, you can set Printer Status and Alerts to notify you when supplies are low.
To check status and order supplies at the control panel
Do one of the following:

Check the supplies status lights on the printer control panel. These lights indicate when a 
print cartridge or the imaging drum is low or empty. The lights also indicate when a non-HP 
print cartridge is first installed. See  “Understanding supplies status ” on page 33 to interpret 
the light patterns.

Press ( GO) and  (CANCELJOB) simultaneously. A Supplies Status page (and the 
Configuration page and, possibly, the HP Jetdirect page) prints. Check the supplies levels on 
the Supplies Status page. See the  HP Color LaserJet 2500 Series Printer User Guide  for 
more information.
If the supplies levels are low, you can order supplies through your local HP dealer, by telephone, 
or online. See chapter 7 for part numbers. See  http://www.hp.com/go/ljsupplies
 to order online.

To check status and order supplies using Printer Status and Alerts
If the printer is directly connected to the computer, you can set Printer Status and Alerts to notify 
you when the supplies are low. On both directly connected and network printers, you can receive 
these messages if you choose to receive alerts about events that do not prevent the printer from 
printing (a print cartridge is low) or that actually prevent the printer from printing (a print cartridge 
is empty). After receiving a message, click  Order Supplies Online in Printer Status and Alerts to 
connect to the Supplies section of the HP website. You must have Internet access to connect to 
the website.
To check status and order supplies using HP Web Jetadmin

information. To order, use the HP Color LaserJet 2500 Series Toolbox or the embedded Web 
server, or see chapter 7.
Storing supplies 
Follow these guidelines for storing print cartridges and the imaging drum:

Do not remove the print cartridge or imaging drum from its package until you are ready to 
use it.
CAUTION To prevent damage, do not expose the print cartridge or imaging drum to light for more than a few 
minutes.

See table 5, “Environmental specifications, ” on page 19 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.

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 printer warranty.
When you insert a supply into the printer, the printer 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 
printer, the printer identifies the supply as non-HP. Simply return the supply to the original printer 
to reactivate HP features and functionality.
Resetting the printer for non-HP supplies
When you install a non-HP print cartridge or imaging drum, the light next to the print cartridge or 
imaging drum you replaced blinks and the Attention light is on. You must press  ( C
ANCELJOB) 
the first time you install this non-HP supply. The status lights will not indicate when this type of 
supply is low or empty.
CAUTION The printer will not stop printing when a non-HP supply is empty. Printer damage can occur if the 
printer attempts to print with an empty print cartridge or imaging drum. See “ Warranty information” 
on page 23.
HP fraud hotline 
Call the HP fraud hotline if the supplies status lights, the embedded Web server, or HP Status 
and Alerts indicates that the print cartridge or imaging drum is not an HP product and you think 
that it is genuine. Hewlett-Packard will help determine if the product is genuine and take steps to 
resolve the problem.
Your print cartridge or imaging drum might not be a genuine HP product if you notice the 
following issues:

You are experiencing a high number of problems with the print cartridge or imaging drum.

The print cartridge or imaging drum does not look like an HP product 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, a language line interpreter will connect approximately one minute after 
the beginning of the call. The language line interpreter is a service that translates between you 
and the representative for the HP fraud hotline.
