Sharp AR-160, AR-161 specifications 10mm

AR-161

1)Making of a test sheet

Make test sheet by drawing parallel lines at 10mm from the both ends of A3 (11" x 17") white paper as shown below. (These lines must be correctly parallel to each other.)

10mm 10mm

10mm 10mm

2)Make a normal (100%) copy of the test sheet on A3 (11" x 17") paper. (Fit the paper edge with the glass holding plate edge.)

3)Measure the distances (La, Lb, Lc, Ld) at the four corners as shown below.

La Lc

Lb Ld

When La = Lb and Lc = Ld, no need to perform the procedures 4) and 5).

4)Move the mirror base B rail position up and down (in the arrow direction) to adjust.

•When La > Lb

Shift the mirror base B rail upward by the half of the difference of La – Lb.

•When La < Lb

Shift the mirror base B rail downward by the half of the difference of Lb – La.

Example: When La = 12mm and Lb = 9mm, shift the mirror base B rail upward by 1.5mm.

•When Lc > Ld

Shift the mirror base B rail downward by the half of the difference of Lc – Ld.

•When Lc < Ld

Shift the mirror base B rail downward by the half of the difference of Ld – Lc.

*When moving the mirror base rail, hold the mirror base rail with your hand.

<Adjustment specification>

La = Lb, Lc = Ld

5)After completion of adjustment, manually turn the mirror base drive pulley, scan the mirror base A and mirror base B fully, and check that the mirror bases are not in contact with each other.

*If the mirror base rail is moved extremely, the mirror base may be in contact with the frame or the original glass. Be careful to avoid this.

(5)Main scanning direction (FR direction) magnification ratio adjustment (SIM 48-1)

Note: Before performing this adjustment, be sure to check that the CCD unit is properly installed.

1) Put a scale on the original table as shown below.

2)Execute SIM 48-1.

3)After warmup, shading is performed and the current set value of the main scanning direction magnification ratio is displayed on the display section in 2 digits.

4)Select the mode and press the start key again.

5)Auto correction mode (AE lamp ON)

The mirror unit moves to the shading position, and the reference width of the reference white plate is scanned, and the correction value is automatically calculated from that scanned value.

The correction value is displayed and a copy is made.

6)Compare the scale image and the actual scale.

If a fine adjustment is required, switch to the manual correction mode with the magnification ratio display key and perform fine adjustment.

7)Manual correction mode (TEXT lamp ON) Enter the set value and press the start key. The set value is stored and a copy is made.
