[A] Reproduction ratio of primary scanning direction (Fine adjustment of polygonal motor
rotation speed (Printer))
<Procedure>
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 (Refer to *).
(3) Check the grid pattern on the test chart printed out and 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.
(Adjustment Mode)  (Key in code [4001])  [START]
 (Key in a value (acceptable values: 0 to 255))
 [OK] 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 A becomes.

(3) Check the grid pattern on the test chart printed out and 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.
(Adjustment Mode)  (Key in the code [4006])  [START]
 (Key in a value (acceptable values: 0 to 255))
 [OK] 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.

e-STUDIO207L/257/307/357/457/507: approx. 0.0423 mm/step
(6) After the adjustment for the code 4006 is completed, apply the same adjustment value for the
code 4005.
(Adjustment Mode)  (Key in the code [4005])  [START]
 (Key in the same value in the step 5 above)
 Press [OK] or [INTERRUPT] (Stored in memory).
