(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 A from the 1st line to the 21st line of the grid pattern.
(4) Check if the distance A is within 200±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance A again.
<Procedure>
(Adjustment Mode) → (Key in code [401]) → [START]
→ (Key in a value (acceptable values: 0 to 255))
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed.

(5) If not, use the following procedure to change values and measure the distance B again.
<Procedure>
(Adjustment Mode) → (Key in the code [411]) → [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 B becomes. (approx. 0.05 mm/
step)
(6) After the adjustment for the code 411 is completed, apply the same adjustment value for the
code 410.
<Procedure>
(Adjustment Mode) → (Key in the code [410]) → [START]
