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 the code [401]) → [START]
→ (Key in a value (acceptable values: 0 to 255))
→ [ENTER] or [INTERRUPT] (Stored in memory)

→ Press [1] → [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance B becomes (approx.
0.04 mm/step).
6. After the adjustment for the code 411 is completed, apply the same adjustment value for the
code 410.
