5. analyze the results of your check in Steps
3-4, using the criteria below:

to adjust the platen position or the main
roller position.
— Platen is Incorrect: the distances between
the straightedge and the main roller at both

bottom. action: adjust the main roller (refer

ship:

tions.
2. place the straightedge across the top of the
platen graphite and the idler roller in a similar
manner to the method shown in figure 51.

of the platen graphite and the idler roller.

— Idler Roller Incorrect: the distances
between the straightedge and the idler
roller at both the top and bottom are more
