P O I N T
The Upper Paper Guides are connected as a single unit with thin
fragile bridges as shown with arrows below. However, these parts
are not to be placed on the shaft holders of the printer frame.
Therefore, it is not necessary to replace the Upper Paper Guides
even if the bridges are broken.
Install the springs properly, while paying attention to the tip
position of each spring.
