2. Press [1]ৎ[PRINTER/NETWORK]. (A grid pattern with 10mm squares is printed out. Use A3/LD from
the 2nd cassette.)
3. Measure the distance C between the 6th (down from the leading edge of the paper) and the 26th grid
lines of the grid pattern.
4. Check if the distance C is within 200±0.5 mm or not.
5. If it is not, use the following procedure to change values and repeat step 2. to 4. above.
<Procedure> (Adjustment mode) ৎ (Enter code [401] with digital keys) ৎ [START]
