If La quals Lb and Lc quals Ld, there is no need to adjustthe
mirrorbase.
Move tie No.2 mirrorbase rafllocationup ordowntoadjust.
If La isgreaterthan Lb:
Shift the paper exit side No.2 mirrorbase rail up hati the dis-
tance betweenLa and Lb.
If La is notgreaterthan Lb:
Shiftthe paper exit side No.2 mirrorbase rail down haffthe dis-
tan~ betweenLa and Lb.
(Example):
If La is 12mm and Lb 9mm, shiftthe paper exit side No.2 mirror
base rail1.5mm up.
r;
(La – Lb)/ 2 = (12 - 9)/2 = 1.5
If Lc is greaterthan Ld:
Shift the paper ent~ stie No.2 mirrorbase rail up half the dis-
tance between Lc and Ld.
If Lc is notgreaterthan Ld:

La becomesqual to Lband Lcto Ld.
Manual~ rotate the mirrorbase dfie pulley to insure that the
mirrorbasesdo notcontacteach other.
NOTE: Move the mirror base rail carefully to prevent possible
damage to the mirrorbases.
