My printer as stopped printing

My printer as just stopped printing.
It's going through all the motions but nothing is coming on the paper.
HELP PLEASE

 

What type of printer is it? The print heads may be blocked. If you look in the utilities section of the printer software there should be a cleaning facility. May take a few runs to clean if it is well blocked

 

The more obvious explanation would be that the ink is finished. If the black and colour ink are in separate cartriges it could be that if one of the two is empty, the other does not work either.

 

I tried everythink changed the ink did all cleaning and checks.
I have now put another set of ink in and it seems to be working O.K a little faint in places.
I'll see how it does .
Might of been a faulty set on ink.
Thanks for replies.
