HP LaserJet 9000 and 9000mfp Series Printers - Installing the Printer Maintenance Kit

Document number bpl10586

Introduction

The parts in the end user installable printer maintenance (PM) kit need to be replaced every 350,000 pages. The printer/mfp control panel will display the message Perform Printer Maintenance when the kit needs to be installed. Replacing the parts in the PM kit is a part of normal printer maintenance.

The printer maintenance kit consists of the following parts:

• One Fuser assembly

• One Transfer Roller assembly

• Seven Feed rollers (two per tray, includes rollers for Tray 4 and one roller for Tray 1)

• Three Pickup rollers (one per tray, includes roller for Tray 4)

   

  NOTE: Variables such as media, environment, and usage can prematurely wear these parts out. See the HP LaserJet Printer Family Print Media Guide (http://www.hp.com/support/ljpaperguide) for more information about suitable media, environment, and use conditions.

   

There are several options for purchasing the printer maintenance kit.

• The Embedded Web Server (EWS) can be configured to e-mail an alert to specified users such as a Systems Administrator when the printer senses that the maintenance kit needs to be installed (the control panel will also display the Perform Printer Maintenance message at this time). From the EWS the printer maintenance kit can be ordered directly from HP. For more information on how to set up and use the EWS, see the Embedded Web Server User Guide (/nav/sitedirector?pageType=manual&lc=en&docName=bpl10150&docSuffix=pdf).

• The printer maintenance kit can also be ordered from the HP Small and Medium Business Store (SMB) Web site, the part number is H3730A for the 110V kit and H3731A for the 220V kit. Customers can also purchase installation of the PM kit along with the kit itself. Click here to view all the HP Care Pack, Warranty/ Service Upgrades and HP Maintenance Kit Replacement services.

Instructions on how to replace the parts included in the maintenance kit

First turn the printer/mfp off and unplug it from its power source. Let it cool down for at least 30 minutes, this allows the fuser to cool off.

1. Open the front door of the printer and rotate the large green lever downward.

2. Pinch the blue tab on the transfer roller assembly and pull it out of the printer. Observe how it is installed before removing it.

3. Reinstall the new transfer roller without touching the black foam roller. Skin oil can contaminate the roller. The new assembly should lock into place when installed correctly.

    

   CAUTION: Be very careful not to touch the black foam roller when handling the new transfer roller.

    

4. Lock the green lever and close the front door.

1. Remove Trays 2 and 3 to access the rollers. There are three rollers per Tray, one pickup and two feed rollers.

2. The rollers come off by squeezing the tab on the end of each roller. Replace each roller one at a time.

3. Open Tray 4 all the way (if equipped) and remove all the paper from the tray. Then gently remove the tray. Replace the rollers the same as Trays 2 and 3.

 

WARNING: Be sure the printer has been turned off and unplugged for at least 30 minutes before attempting to remove the fuser. The Fuser may be very hot.

1. If the printer is equipped with a High Capacity Output Device (HCO), pull it away from the printer far enough to allow the left door to be fully opened. Then open the left door.

2. Remove the Duplexer (if equipped) by pushing downward on the green tab and slide the duplexer out.

3. Rotate the small blue levers on each side of the fuser toward the center to unlock the fuser.

4. Lift up on the finger handle slightly and pull it away from the printer until it stops.

5. Grab the blue handle on the top of the fuser and lift up on the fuser to remove it. Use the finger handle as well to prevent the fuser from being dropped.

6. Before reinstalling the new fuser, remove any orange packing material.

7. After reinstalling the new fuser, be sure to lock it into place with the small blue levers.

8. Reinstall the Duplexer (if equipped).

9. Power up the printer/mfp and clear the Perform User Maintenance message from the control panel using the following instructions.
