HP Laserjet 4200, 4300 Maintenance Kit Replacement Procedure Instructions
HP Laserjet 4200, 4300 maintenance kit Replacement Procedure Instructions
The HP laserjet 4200, 4300 printer maintenance kit provides you with the most commonly used parts that wear throughout the machines. I have several HP laserjet 4200’s and 4300’s in the field that the only time I get calls on the machine are for maintenance kit replacement.
Replacing these worn maintenance kit parts will allow for maximum paper feed, quality print performance, and reduce the need for unwanted service calls. Everybody is always looking for the HP laserjet 4200, 4300 maintenance kit reset procedure to just reset the maintenance counter. I strongly advice avoiding this tactic. HP has done a good job at rating these maintenance kit parts to their full life cycle. If you just reset the maintenance kit message and neglect to replace the parts you will be calling in for service shortly after for image or feed problems that could have been avoided if you had just installed the user maintenance kit when advised.

5. Locate the feed roller in the top of the tray cavity.
6. Repeat steps 3 and 4
Make sure you double-check the rollers by pulling on them slightly to make sure they have locked. It’s easy for even seasoned technicians to quickly install these feed rollers and then 20 to 30 prints later have jam issues because they didn’t verify the rollers were truly locked in place. Been there, done that.
NOTE: The removal and replacement process are the same for the feed and separation rollers on tray 3 and the 1500 sheet feeder.
