ADJUSTMENT
3 - 9
[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 from the lower
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 [401]) [START]
(Key in a value (acceptable values: 0 to 255))
[ENTER] 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 (approx. 0.125 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 from the lower
drawer (Refer to *).
(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 [411]) [START]
(Key in a value (acceptable values: 0 to 255))
[ENTER] 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).
(6) After the adjustment for the code 411 is completed, apply the same adjustment value for the
code 410.
(Adjustment Mode) (Key in the code [410]) [START]
(Key in the same value in the step 5 above)
Press [ENTER] or [INTERRUPT] (Stored in memory).
Note:
Make sure the first line of the grid pattern is printed out since the line is occasionally vanished.
