[A] Reproduction ratio of primary scanning direction (Fine adjustment of polygonal motor
rotation speed (Printer))
<Procedure>
(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 in the 2nd
drawer.
(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.
(e-STUDIO556/656: 0.3 mm/step, e-STUDIO756/856: 0.1 mm/step)
[B] Primary scanning data laser writing start position (Printer)
<Procedure>
(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 in the 2nd
drawer.
(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 (approx. 0.05 mm/
step).
Make sure the first line of the grid pattern is printed out since the line is occasionally vanished.
[C] Reproduction ratio of secondary scanning direction (Fine adjustment of transfer belt motor
rotation speed (Copier/Printer))
