APER EEL ARRIER INCH OLLER PRINGS
A spring is fitted at each end of the paper reel carrier to force the pinch roller into contact with the paper.
Although the springs are identical, they must be fitted in the correct manner (see Figure 5) always remove
and install one spring at a time. Early printers are fitted with springs made from 0.55 mm diameter wire;
later printers are fitted with springs made from 0.60 mm diameter wire. Whenever these springs are to
be changed, the thicker springs should be fitted, regardless of whether the printer is an early or later
version.
