HP LaserJet 5Si, 8000, 8100, 8150: Maintenance Kit Instructions

FUSER REPLACEMENT. (Refer to Figure A)

  1. Turn the printer off. Warning: The fuser may be hot! Either wait for it to cool before proceeding further, or handle it with caution.
  2. Open the left door. If a duplexer is installed, remove it by pressing down on the green lever and pulling the duplexer toward you.
  3. Rotate the blue fuser locking levers downward to unlock the fuser, and then remove the fuser by lifting up on the finger handles while pulling outward.
  4. Reverse steps 2-3 to install the new fuser. Make sure the locking levers are down while installing the fuser, and rotate them up after installation to lock the fuser in. Also be sure to place the two envelope levers in the down position after installation.

TRANSFER ROLLER REPLACEMENT: Refer to Fig. B)

  1. Open the top cover and remove the toner cartridge. Avoid exposing the cartridge to light for prolonged periods; i.e., put it in a dark place or cover it while it is out of the printer.
  2. The transfer roller is mounted to the floor of the printer. To remove it, use a screwdriver or pick to lift the left end of the metal shaft, and then slide the roller to the left to free the right end.
  3. Unclip the transfer guide from the old roller and clip it onto the new one. Take care not to touch the rubber surface of the transfer roller – wear rubber gloves or handle the metal shaft only.
  4. To install the new roller, slide the non-gear end of the shaft into the right holder, then, while holding the transfer guide up, push down on the left end of the shaft until it snaps in. Finally, press the transfer guide down until it snaps in. If the roller has a protective paper sleeve, remove the sleeve after installing the roller.

FEED/SEPARATION ROLLER REPLACEMENT: Refer to Figs. C, D

  1. The same two feed/separation rollers (identifiable by blue plastic, as opposed to the black plastic of the pickup roller) are used for all 500-sheet cassettes – trays 2 and 3 in the main printer body, and trays 4 and 5 in the optional 2x500-sheet feeder – as well as for the optional 2000-sheet feeder (tray 4).
  2. The maintenance kit includes four pairs of these rollers, for up to four trays.
  3. Removal and installation of the rollers is the same in all cases: squeeze the retaining tab and slide the roller off the shaft; then slide the new roller onto the shaft and rotate it until it locks in.
  4. However, the procedure for accessing the rollers differs for 500-sheet cassettes vs. the 2000-sheet drawer.
  5. 500-sheet cassettes: 1. Remove the paper cassette from the printer. To do this, open it all the way to the stops, press the colored tab on the right side (8100/8150 only – the others do not have this tab), lift the front end slightly to clear the stops, and pull it the rest of the way out. 2. Replace the two rollers as described above. 3. To reinstall the cassette, align the left and center of the cassette with their respective guides in the printer, and push the cassette an inch or two into the printer. Then lift it slightly while pulling the tray stop mechanism (located at the right rear) out and over the roller and guide assembly on the cassette. Finally, push it in the rest of the way
  6. 2000-sheet drawer: 1. Open the vertical transfer door on the right side of the feeder to access the rollers. (Fig. 5) 2. Replace the two rollers as described above. 3. Close the vertical transfer door.

RESETTING THE MAINTENANCE MESSAGE/COUNT: 5Si

  1. If the display is showing “Perform User Maintenance,” go into the Configuration Menu, find “Service Message = On,” and use the + key to change it to “Off.” Then press Select to save this setting.
  2. If you have installed the maintenance kit prematurely, before the “Perform User Maintenance” message comes up, you will not find the service message in the menu. In this case, you will have to go into the service mode and edit the maintenance count:
    1. Turn the printer off. Then press and hold Items and + while powering on. Continue to hold these keys until all display lights are on, then release them
    2. Press and release Select. The display will briefly show “Service Mode” and return to this after initializing.
    3. Go into the Service Menu and set “Maintenance Count” to zero, one digit at a time (+ changes the underlined digit; Select sets that digit and moves to the next one – make sure to select all digits). When finished, press Menus followed by On Line to exit the service mode.
    4. Print a configuration page. This should cause the “Perform User Maintenance” message to appear. Now go back and perform step 1 to turn off the message and reset the count.

RESETTING THE MAINTENANCE MESSAGE/COUNT: 8000/8100/8150

  1. Turn the printer off. Then press and hold the left (“-“) side of both the Item and Value keys while powering on. Continue holding these keys until the display reads “Reset Maintenance Count” (on some printers, it will read “Count”), then release them. Once the display goes to “Ready,” print a configuration page and check that “Pages Since Last Maintenance” has gone to zero. If not, go to step 2.
  2. In some cases (especially if the maintenance kit is installed prematurely – before the “Perform User Maintenance” message comes up), step 1 may not work. In these cases, you will have to go into service mode and directly manipulate the maintenance count:
    1. Turn the printer off. Then press and hold Select and Cancel Job while powering on. Continue to hold these keys until all display lights are on, then release them.
    2. Press and release the right side of Menu, then Select. The display will briefly show “Service Mode” and return to this after initializing.
    3. Go into the Service Menu and set “Maintenance Count” to zero, one digit at a time (Value changes the underlined digit; Select sets that digit and moves to the next one – make sure to select all digits). When finished, press Go twice to exit the service mode. Caution: Do not change the “Maintenance Interval” – in particular, do not set it to zero! This can cause a permanent “49” error and necessitate replacement of the formatter board.
    4. Print a configuration page. One of two things will happen:
      1. “Pages Since Last Maintenance” will have gone to zero (in this case, no further action is required);
      2. “Perform User Maintenance” will come up on the display. In this case, go back and perform step 1, which will now work.
