Basic printer troubleshooting
The printer does not print
If all is in order (paper loaded, all ink components installed, and no file errors), there are still reasons
why a file you have sent from your computer may not start printing when expected:
1. You may have an electrical power problem. If there is no activity at all from the printer, and the
front panel does not respond, check that the power cord is connected correctly and that there is
power available at the socket.
2. You may be experiencing unusual electromagnetic phenomena, such as strong electromagnetic
fields or severe electrical disturbances, which can cause the printer to behave strangely or even
stop working. In this case, turn off the printer using the power key on the front panel and unplug
the power cord, wait until the electromagnetic environment has returned to normal, then turn it on
again. If you still experience problems, please contact your customer service representative.
3. You may not have installed in your computer the correct driver for your printer.
4. If you are printing on a sheet, you must specify Printer Autoselect or Single-Sheet or Multi-Sheet
Tray as the paper source in your printer driver.
The Front Panel is blank (the printer does not start)
If the printer does not start (the front panel is blank), try the following:
Remote troubleshooting
1. Ask the customer to unplug and plug in the power cord. The customer should check when the
power cord is plugged in that the front panel is illuminated (white) for a few moments, after which
the printer should start the initialization process.
2. If the front panel is still blank (does not show a flashing white screen), and the printer does not
start up, then ask the customer to hold down the Power key for a few seconds and ask to check
whether the Power LED button turns orange while the key is held down.
3. If the customer does not see the orange light, no power is reaching the printer; ask to check that
the power cord is correctly plugged in. If the problem persists, there is a problem with the power
supply. Arrange a service engineer visit to replace the Power Supply, see
Power Supply
on page 202.

4. If the customer sees the orange light, ask to unplug and plug in the power cord and to listen and
wait for around 30 seconds for the printer to make a beeping sound.
5. Three beeps mean that the Front Panel has failed or the Front Panel cable is disconnected or
damaged. Arrange a service engineer visit to check the cable and replace the Front Panel if
needed, see
Front Panel on page 165.

6. One long beep means an electronic problem. Arrange for a service engineer visit to replace the
Main PCA. To check that the Main PCA is broken you can ask the customer to open the Ink
Cartridge Cover and check whether there is a green light (heartbeat LED) flashing in the left
bottom part .
