[A] Reproduction ratio of primary scanning direction (Fine adjustment of polygonal motor rotation
speed (Printer))
(1) While pressing [0] and [5] simultaneously, turn the power ON.

(Adjustment Mode)
(2) Press [1]

[FAX]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from the lower
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.

(3) Measure the distance B from the left edge of the paper to the 6th line of the grid pattern.
(4) Check if the distance B is within 52±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance B again.

(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.
