1. 6. 3 Printer related adjustment

(a) Reproduction ratio adjustment of primary scanning direction (Fine adjustment of polygonal motor

rotation speed)
1. While pressing the digital keys [0] and [5] simultaneously, turn ON the power.→(Adjustment mode)
2. Press [1]→[SETTINGS]. (A grid pattern with 10 mm squares illustrated later is printed out. Use A3
(LD) from the 2nd cassette.)
3. Measure the distance A from the first grid line at the rear to the 21st of the grid pattern.
4. Check if the distance A is within 200 ± 0.5 mm or not.
5. If it is not, use the following procedure to change values and repeat the steps 2. to 4. above.
<Procedure> (Adjustment mode)→(Input code [400] with digital keys)→[START]
→(Input a value (acceptable values: 1209 to 1235) with digital keys)
→[SET] icon or [INTERRUPT] key (Stored in memory)
→(Input code [407] with digital keys)→[START]
→Color registration control forced performing
*The larger the adjustment value, the shorter the distance A becomes
(0.082 %/step = 0.164 mm/step).
(b) Primary-scanning data write start position adjustment
1. While pressing the digital keys [0] and [5] simultaneously, turn ON the power.→(Adjustment mode)
2. Press [1]→[SETTINGS]. (A grid pattern with 10 mm squares is printed out. Use A3 (LD) from the 2nd
cassette.)
3. Measure the distance B from the front edge of the paper to the 1st grid line from the front of the grid
pattern.
4. Check if the distance B is within 5 ± 0.5 mm or not.
5. If it is not, use the following procedure to change values and repeat the steps 2 to 4 above.
<Procedure> (Adjustment mode)→(Input code [470] with digital keys)→[START]
→(Input a value (acceptable values: 0 to 255) with digital keys)
→[SET] icon or [INTERRUPT] key (Stored in memory).
→(Input code [407] with digital keys)→[START]
→Color registration control forced performing
*The larger the adjustment value, the longer the distance B becomes
(0.0423 mm/step).
