How to install fuser maintenance kit on the HP LaserJet 4200 4250 4350 4300

Turn the printer off and unplug the power cord. The fuser might be hot if you have been using the printer. As a safety precaution wait 30 minutes for the fuser to cool before proceeding.

Important Note: After you install your new fuser, you may hear excessive gear noise if the printer’s Swing Plate Drive Gear is worn out. The new gears on the new fuser may not mesh well with worn-out drive gears in your printer, causing grinding or rumbling noises. The most common culprit is the black plastic swing plate gear pictured below. This gear is a high failure rate part. So if you install a new fuser, and you begin hearing a grinding noise, you’ll want to examine your swing plate drive gear for wear and tear.

When handling the replacement transfer roller be careful not to touch the black roller surface. Oils from your skin can adversely affect print quality. Some people recommend wearing latex gloves when handling the transfer roller but it isn’t necessary if you are careful to only touch the ends. It is unlikely that you would ever notice poor print quality from accidentally touching the transfer roller’s surface.

Insert the right end of the new transfer roller first. Follow with the left end, making sure the black plastic clip at the left end of the roller is oriented with the open end facing down. When the transfer roller is seated comfortably in its slot, press down on the black plastic clip to snap the clip in place.

Resetting the maintenance count.

If the display panel on your HP LaserJet reads “perform printer maintenance”, “perform user maintenance”, or anything along those lines it means your printer needs a preventative maintenance kit. Once you have installed the maintenance kit the message will only go away if you reset the maintenance count. (Even if the message is not being displayed, the maintenance count needs to be reset.)

Reset the maintenance count on an HP LaserJet 4200, 4300, 4250, 4350

1. Turn the printer off.

2. Turn the printer back on and, as the memory begins counting, press & hold down the checkmark button while the memory is counting. The memory starts counting at 000MB immediately after you turn the power on. If you press the checkmark buttong too soon – before the memory starts counting – this procedure won’t work.

3. Continue to hold down the checkmark button until all three LEDs are illuminated.

4. Release the checkmark button.

5. Press the up arrow (Navigation) button until the message “New Maintenance Kit” appears on the control panel display.

6. Press the checkmark button once.

A message “New Maintenance Kit ” will appear in the control panel display and the printer will be reset.

Once the maintenance count has been reset the “Perform Printer Maintenance” message won’t appear again until the maintenance interval has been reached (200,000 pages on a LaserJet 4200, 4250, 4300, and 4350 series printers).

Here are two short video clips showing how to punch down a CAT5e or CAT6 UTP cable onto a Keystone Jack. Keep in mind that for Voice/Data applications we use the standard T568B  and simply match the wire colors to the T568B color patterns on the jack itself. Always be sure to punch straight down onto jack, sometimes installers have a tendency to slightly shift the tool on an angle (usually because of rushing, inexperience, or both) which can cause damage to the jack.  Be sure to remove any uncut wires from the sides of the jack by using a circular motion to break wire off the jack (in case tool didn’t cut during the punch).
