[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)
Press [98] → [FAX]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from the 2nd
(2)
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.
<Procedure>
(Adjustment Mode) → (Key in the code [401]) → [START]
→ (Key in a value (acceptable values: 0 to 255))
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed.
→ Press [98] → [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance A becomes (approx. 0.08 mm/
step).
[B] Primary scanning data laser writing start position (Printer)
While pressing [0] and [5] simultaneously, turn the power ON. → (Adjustment Mode)
(1)
Press [98] → [FAX]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from the 2nd
(2)
drawer.)
(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.
<Procedure>
(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 [98] → [FAX] → (A grid pattern is printed out.))
* The larger the adjustment value is, the longer the distance B becomes (approx. 0.04 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.
