Have you ever encountered before the problem of having multiple paper loading in your HP LaserJet 5L and 6L? Do you know that this is caused by a defective separation pad where it's rubber has worn out. The function of separation pad is to control or allow paper to go through it, one at a time.
If it spoilt, few sheets of paper will be pulled instead of one whenever you send a printer command. This sometimes will caused the papers to jammed up. For the worst case, it will spoil your heating/fuser sleeve. The price of a heating element is more expensive than a separation pad. There is one temporary way that you can use to solve the problem stated without buying a new separation pad. The process of removing and changing the separation pad is just easy and fast. Firstly, remove the rubber pad from the holder. Be careful while you're removing because you mighttorn the rubber into pieces. Secondly, clean the holder to prevent any dirt or glue sticking on it. After that, apply a small amount of super glue that is just enough to cover the full surface of the rubber pad.Finally, reversed the rubber pad and stick it back to the holder. Please ensure that the surface should face upward before you stick the rubber pad. It will work as good as a new one.
Note: If you are servicing the printer for your customer, I'll recommend you to replace a new one for them unless you’re maintaining and servicing your own laser printer.
Testing Capacitor-How to test a capacitor when breakdown under load.
Have you ever come across power problem where onceyou switch on the power supply and the fuse blow? Youhave checked all the components in the power (primary)and secondary section and all the components seems to beok! Where is the fault? A fuse blown are usually causedby a shorted bridge rectifier, defective posistor, powertransistor or FET, shorted primary winding of switch modepower tranformer, shorted secondary diode and etc. Butin this article i'm gone to show you another secret of electronic troubleshooting tips.
