1 - HI Blanka. What’s the matter?, 2 - It’s my printer. It won’t give me clean print-outs of anything. It just messes them up, 3 - What exactly do you mean by “messes them up”?, 4 - Well, it keeps on missing lines and you can hardly read it., 5 - Oh. that sounds like you need to change the cartridge. That should sort it out., 6 - No, it’s not the cartridge. It’s a new cartridge, 7 - Hmm, well, if it’s not the cartridge, it sounds as though it could simply be a printing-head problem. Have you tried cleaning them?, 8 - No, I don’t know I had to., 9 - Yes, the best thing would be to clean them. I’ll show you. There, that should solve the problem, 10 - Oh that’s so much better. Thanks, Gareth!,
