3. CHAPTER 8 CARING FOR YOUR PRINTER Subjects we ll cover in Chapter 8 include e Cleaning the printer Changing the ribbon e Replacing the print head As any good mechanic will tell you dust and heat are the big gest enemies of any mechanism And your printer is no excep tion The best maintenance is preventive maintenance so the first step in keeping your printer healthy and happy is to make sure it s in a clean dust free location The range of temperature should be comfortable for both you and your computer printer system Please refer to Chapter 1 for more tips on locating your printer CLEANING THE PRINTER Another important rule for keeping your printer young and healthy is to clean it regularly inside and out Just use a damp towel every week or so you can moisten the towel with alcohol for stubborn dirt but be careful not to get any alcohol on the printer mechanism Use a soft brush to remove dust and lint from wside the printer but be very careful not to bend or injure any electronic parts or wiring It doesn t take much to do expensive damage so don t fuss where you re not supposed to besides periodic cleaning the only other maintenance you ll have to do will be changing the ribbon cartridge or the print head 124 REPLACING THE RIBBON This printer uses an endless ribbon cartridge which means that the inked ribbon inside is recycled automatically Eventual ly though pri
