You have to clean or renew the ink pads at the back of the printer after removing the cover - these are the parts that need maintenance !
There is a counter program inside the printer and when it reaches 8300, the printer will not work and this is when you get the maintenance required message...
You have to reset the counter before the printer will work OK again and this is what the software does - downlaod it from here... cheaper than taking it to an Epsom dealer then be
pursuaded to buy a new printer... http://www.ianwillis.co.uk/c42/
