No power to the printer.
1) Either the power adapter is not connected properly.Remove the power cord from main power outlet and connect it to any other electric outlet.Also at the back of the printer there is a socket where the power got get connected.Remove power wire from there too and reconnect it.
2) If the problem is not solved then there are two possibilities:--
A) The power cord is faulty and needs replacement.
B) Or the printer circuit board is got short and it has to be replaced.
In both the cases A as well as B you need to get the fault checked by other spare power adapter or power supply board in printer.At local printer repair shops they have this parts in spare.They will get the fault checked and let you know that which part has to be replaced.Either the power adapter or power supply board.The cost of new power adapter is near to $10 and cost of new power supply board is near to $40.
One more thing i want you to check is.In your printer power adapter there is one three pin power wire is connected.That three pin power wire wire goes from main power outlet to the printer adapter.In some cases that three pin power adapter gets faulty.If that three pin power wire is faulty then the cost of that power wire is just $2.So get that three pin power wire also checked.
To see how this three pin power wire looks.See the fig below:---
If this wire is faulty then its not much costly.
This are all the possibilities that you will have to get checked.To get the fault confirmed.Thanks.Helpmech.
Failurre of the power supply .This is Switch mode Power Supply unit and it ispossible that the fuse blew off. But if replaced fuse blows then the surrge protector, the recifier, the filter main capapcitor or the OSC IC/ driver can be defective.
Check for spares or replace as a whole unit.( it is plug and push unit and can be DIY)
open all case. power supply bored is seen.removable an 8 pin ic is seen. exchange ic from the one same ic besides the secondary memory ****. and transfer jumper lug downward.power on unit for 2 sec. return jumper lug up. power on unit. unit is now ok
