I didn't know you get cleaning paper for laser printers, but I assume it cleans the surplus? toner off the drum, you could try it on your inkjet I suppose. Have heard that a big sheet of blotting paper cut to A4 and Form fed through an inkjet wil pick a lot of stuff but never tried it. others swear by a sheet of very fine wet&Dry paper, the kind for rubbing down a car prior to painting, can be useful. Top feeding printers are obviously more prone to dirt pick-up so a cover might be useful when printer is not in use?
Be interesting to hear what others say.
