[C] Image position adjustment of the primary scannin g direction

(1) While pressing [0] and [5] simultaneously, turn  the power ON.  (Adjustment Mode)
(2) Place a ruler on the original glass with its lea ding edge pushed against the rear side and its side  
along the original scale on the left.
(3) Press [FAX] to make a copy at the mode of A3 (LD ), 100% and standard drawer of the equipment 
(Refer to *). 
*Perform 08-477 and check the value. 
If the value is 0, use the lower drawer. 
If the value is 1, use the upper drawer.
(4) Measure the distance B from the left edge of the  paper to 10 mm of the copied image of the ruler.
(5) Check if the distance B is within the range of 1 0±0.5 mm.
(6) If not, use the following procedure to change val ues and repeat the steps (3) to (5) above.
(Adjustment Mode)   (Key in the code [306])   [START]
  (Key in a value (acceptable values: 0 to 255))
  Press the [ENTER] or the [INTERRUPT] button (store d in memory).
  (“100% A” is displayed.)
*The smaller the adjustment value is, the more the  image is shifted to the left and the distance B 
becomes narrower (0.085 mm/step).
