[C] Reproduction ratio of secondary scanning direction (Fine adjustment of main motor rota-
tion speed (Copier/Printer))
While pressing [0] and [5] simultaneously, turn the power ON. → (Adjustment mode)
(1)
Press [1] → [FAX]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from the lower
(2)
drawer.)
(3) Measure the distance C from the 2nd line at the leading edge of the paper to the 22nd line of the
grid pattern.
* Normally, the 1st line of the grid pattern is not printed.
(4) Check if the distance C is within 200±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance C again.
<Procedure>
(Adjustment Mode) → (Key in code [421]) → [START]
→ (Key in a value (acceptable values: 0 to 255))
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed
→ Press [1] → [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance C becomes. (approx. 0.125 mm/
step)
[D] Secondary scanning data laser writing start position
This adjustment has to be performed for each paper source.

(3) Measure the distance D from the leading edge of the paper to the 6th line of the grid pattern.
* Normally, the 1st line of the grid pattern is not printed.
* At the duplexing, measure it on the top side of the grid pattern.
(4) Check if the distance D is within 52±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance D again.
<Procedure>
(Adjustment Mode) → (Key in the code shown above with digital keys) → [START]
→ (Key in an acceptable value shown above with digital keys)
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed
→ Press [1] ([3] for duplexing)
→ [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance D becomes. (approx. 0.4 mm/step)
