(c) Reproduction ratio adjustment of secondary scanning direction (Fine adjustment of transfer belt mo- tor 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 illustrated later is printed out. Use A3 (LD) from the 2nd cassette.)

3.Measure the distance C from the 6th to 26th grid lines of the grid pattern.

4.Check if the distance C 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 [401] with digital keys)[START](Input a value (ac-

 

ceptable values: 1327 to 1382) 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 C becomes (0.074 %/step =

0.15mm/step).

(d)Secondary-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]. (The following grid pattern is printed out. Use A3 (LD) from the 2nd cassette.)

3.Measure the distance D from the leading edge of the paper to the 6th grid line of the grid pattern.

4.Check if the distance D is within 55 ± 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 [474] with digital keys)[START](Input a value (ac-

 

ceptable values: 0 to 15) 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 D becomes (0.6 mm/step).

Note: The reproduction ratio adjustment and the data write start position adjustment in the primary and secondary scanning directions have a connection as shown below.

1.When [05-400] is adjusted, [05-401, 402, 403, 404 and 474] are automatically adjusted.

2.When [05-401] is adjusted, [05-402, 403, 404 and 474] are automatically adjusted.

3.When [05-406] is adjusted, [05-404] is automatically adjusted.
