Powers off on own while printing

Year, make, model, and engine size?

if power light is on most of the set inside is on.

Follow power cord inside set and on power supply board look for up to three rectangular black relays that are there-----they will be marked with relay voltage in white.

Gently tap with something not metal on each until the power light goes off.

What happens is one of the relays sticks in the closed position.

If the power light goes off when you do this the relay is bad and if there are three the part number is printed on them----replace all three as they each have only 4 solder connections and are generally under 10 dollars each (wholesale about half that).

If tapping stops it sooner or later it will do the same thing again.

Try removing and reinserting the cartridges. Remove and reinsert the USB Cable from the back of the printer. Unplug the power cord and plug it back in from the back of the printer.
If the printer is still turned off use the power button to turn it on.

There might be documents that are stuck on the queue. So in order for you to remove that.
Type services.msc on the run command if you OS is a Windows XP. If it's Vista or 7. Type it in the search box on your start menu.
Look for Print Spooler under the list of services.
Right Click on the Print Spooler, Click Stop Right Click on the Print Spooler again and click Start.
Restart the computer.
Try Printing again. ^_^

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

If you try the print head alignment or head cleaning wizard under the maintenance tab, they may help!
