7.5.2 Vertical Timing Pattern Adjustment Procedure
1. Press the PAPER REV (6) key and observe that the printer display
changes to [.U E P]. The Vertical Timing Pattern is printed. Fig-
ure 7–4A represents a magnified view of three of the 25 vertical bars
that are actually printed. Press the FCT (9) key to stop printing the
pattern; press the FCT (9) key again to resume printing the same
pattern.
2. If the printout of the pattern consisting of three level evenly spaced
dots flanking six level evenly spaced dots is the same as Figure 7–4A,
proceed directly to Horizontal Timing Pattern Adjustment (see Sec-
tion 7.5.3).
3. If the printout is not the same as Figure 7–4A, follow the instruc-
tions given with the figure (Figure 7–4B or C) that matches your
printout. When the adjustments have been made to produce the
printout shown in Figure 7–4A, proceed to Horizontal Timing Pat-
tern Adjustment (see Section 7.5.3).
NOTE
In rare cases, the printer may lock up if R27 is overadjusted.
This lockup can be cleared by turning the printer power switch
OFF, then ON again.
