[B] Reproduction ratio adjustment of primary scanning direction
(1) While pressing [0] and [5] simultaneously, turn the power ON.
→
(Adjustment Mode)
(2) Place Test Chart No. TCC-1 on the original glass (with the arrow positioned at the left rear side).
(3) Press [FAX]
→
[START] to make a copy at the mode of A4/LT, 100%, Black and Text/Photo.
(4) Measure the distance A between M1 and M2 on the copy with a ruler.
(5) Check if the distance A is within 200±0.5 mm.
(6) If not, use the following procedure to change values and repeat step 3. to 5. above.
<Procedure>
(Adjustment Mode)
→
(Key in the code [405])
→
[START]
→
(Key in a value (acceptable values: 0 to 255) with digital keys)
→
[ENTER] or [INTERRUPT] (Stored in memory)
* The larger the adjustment value is, the longer the distance A becomes (approx. 0.1
mm/step).
[C] Image location of primary scanning direction
(1) While pressing [0] and [5] simultaneously, turn the power ON.
→
(Adjustment Mode)
(2) Place Test Chart No. TCC-1 on the original glass (with the arrow positioned at the left rear side).
(3) Press [FAX]
→
[START] to make a copy at the mode of A4/LT, 100%, Black and Text/Photo.
(4) Measure the distance B from the left paper edge to the 10 mm line of left grid pattern on the copy
with a ruler.
(5) Check if the distance B is within 10±0.5 mm.
(6) If not, use the following procedure to change values and repeat step 3. to 5. above.

[START]
→
(Key in a value (acceptable values: 0 to 255))
→
[ENTER] or [INTERRUPT] (Stored in memory)
* The larger the adjustment value is, the longer the distance B becomes (approx. 0.04 mm/
step).
[D] Reproduction ratio of secondary scanning direction
(1) While pressing [0] and [5] simultaneously, turn the power ON.

[START]
→
(Key in a value (acceptable values: 0 to 255))
→
[ENTER] or [INTERRUPT] (Stored in memory)
