This is solution for problem when you press copy button on printer,nothing happens
- Connect your printer to computer. Open the scanner lid on printer and run scan function from computer. If you can see scanner moving but its light not glowing or scanner does not move,then it is scanner problem. In this case you need to contact hp service support.
If scan function is working fine,then it is problem with your copy buttons (It was in my case)
Things required to repair this problem:
- Soldering iron and soldering wire
- Soldering skills
- Multimeter (any cheap one will do fine)
- Multibit Screwdriver
1.Disassemble the button panel of printer by prying it from corners. It does not have screws
4.You can see every button have 4 legs. You need to test continuity (connectivity) of these legs with help of multimeter.
5.Look this picture for knowing on which pins to check connectivity.
- Set your multimeter to beep mode. Touch one probe of multimeter to pin number 1 and second probe to pin number 3. You will not be getting any beep sound. Keep these probes connected to both pins and press the button. You should hear beep sound. Test same with pin number 2 and 4
If you get connectivity between 1 and 3 pin and 2 and 4 when you press the button. This means your buttons are fine, If you don’t have connectivity between these buttons,It means these buttons are faulty. Check all other buttons too.
