50.8 fuser error – HP Color Laserjet 3000, 3600, 3800, and CP3505

HP used to give you just one or two general error codes for fusers. Now they are getting more specific in detail so you can troubleshoot errors like the 50.8 fuser error, making them easier and hopefully resolving the issue without buying unwanted parts.   One important issue that has been known to cause problems with fusers is surge arrest or power strips. More and more electrical devices are being used in offices everyday. With that comes power strips to make sure everything can be plugged in and used. LaserJets are like big heaters, they draw a lot of power so they need to be plugged into their own socket and make sure no other heating device like a   coffee maker, copier, or space heater is plugged into the same circuit. The HP Color Laserjet 3000, 3600, 3800, and CP3505 machines  have a certain time frame in which to get to ittheir correct operating temperature so if other large devices are drawing power on the same circuit it could cause these machines to work incorrectly. If you were to call HP one of the first questions they always ask is if the machine is plugged straight into the wall or on a power strip or battery back up. If the  HP Color Laserjet 3000, 3600, 3800, and CP3505 doesn’t get to that temperature in time it will throw you possibly a 50.8 fuser error meaning the sub thermistor is reading an incorrect value.
