nothing happens (nothing is dis-
played, no noise). Switch off the printer and proceed as follows:
1 Check that the power plug is correctly connected to the socket
on the printer.
2 Check that the power plug is seated properly in the wall socket.
3 Switch on the printer again. If the printer is now connected cor-
rectly, the printer initializes and text is shown on the display.
If these steps do not eliminate the fault:
` Replace the power cord and repeat step 3.
`
Check whether the fuse is faulty and if so exchange it:, see
