New Plain Black Group 4 Typewriter Ribbon for Olivetti
New plain black typewriter Group 4 ribbon for Olivetti typewriters which includes Lettera 22 , 32 ,82 , Studio 35 ,42 ,44 , 45 ,46 , Valentine , Dora and Roma . It comes on two Group 4 plastic spools . These should drop into your Olivetti manual machine or we would recommend in most cases that you rewind this new ribbon onto the existing spools in your typewriter , if it has the original metal spools .These ribbon spools will also suit later Underwood portable typewriters as they were basically Olivetti models such as the Underwood 310 and 315.
It's also a good idea to take a photo of the way the ribbon is threaded through the " ribbon throw " in the centre of the typewriter . You then have something to refer to when you have taken the old ribbon out and are trying to fit your new ribbon .
Our ribbons are 10 m long and the standard 1/2 inch width , with a good level of black ink in them. The plastic spools that the ribbon comes on are 5.3 cms in diameter , with the central hole 7 mm in diameter .The ribbon passes from one spool to other by moving fractionally every time you type , and then returns back from the full spool to the empty one again .This process can be repeated many times and for someone typing 40 hours a week in an office a ribbon would last around 3 months .
The ribbon comes in a sealed plastic bag and as long as you keep it sealed and out of direct sunlight will be fine for a long period of time .
Delivery anywhere within Australia is included in the price .
