A:I've just got a new printer . How often do I need to replace the print heads ? B: Well , under normal conditions each head lasts about 5 000 copies or so . It depends on the user , but about once a month is average . A: So if I don't print out very much , it could last a lot longer ? B: That's right . It could <MASK> or more . This model's designed for heavy use . Don't worry - you'll get an error message telling you when to change the head .
