HP laser jet 138 fnw printer main laser scanner is not working problem solved.

HP laser jet 138 fnw printer / 136a & 136w printer main laser scanner is not working problem solved. Friends, today I will show you how to fix the main scanner if the scanner is not working properly on the hp laserjet MFP 138 FMW printer? Sometimes it happens that the printer turns on but there is no sound, the display comes on, the printer goes to the ready to copy option, but when you press the copy button, it says copy, and after a while shows an error code #U2-1113. In this case, you can check the scanner cable and scanner unit firstly by repix, if it does not solve the problem, then definitely change the scanner and scanner cable, your problem will be solved. Or if it is the case that your printer is turning on and the sound is continuous and does not stop, it could be a problem with the mains scanner. Sometimes, if the voltage drops below 220 at home or office, then this type of problem can occur, then you need to check the voltage. If the voltage is OK then the printer problem is confirmed.
