5. Changing a tray's paper size setting

Follow these steps to change a tray's paper size setting.

Note:

•The paper size setting cannot be changed when the machine has stopped temporarily due to running out of paper or a misfeed, or during interrupt copying.

•During printing (even in copy mode), the paper size setting cannot be changed.

•Do not load paper that is a different size than the paper size setting. Copying will not be possible.

1) Hold down the [PAPER SIZE ENTER] key for more than 5 seconds to

set the selected paper size. The currently selected paper feed location indicator will blink and the corresponding paper size (which is currently set) indicator will light steadily. All other indicators will go out.

3) Squeeze the lock lever of the front guide and slide the front guide to match the width of the paper, and move the left guide to the appropriate slot as marked on the tray.

Left guide

Front guide

•The front guide is a slide-type guide. Grasp the locking knob on the

guide and slide the guide to the indicator line of the paper to be loaded.

•The left guide is an insert-type guide. Remove it and then insert it at the

indicator line of the paper to be loaded.

•When using 11" x 17" sized paper store the left guide in the slot at the

left front of the paper tray.

2) Use the [ORIGINAL SIZE ENTER] key to select the paper size. The indicator of the selected paper size lights up.

4) Press the [START] key and then the [PAPER SIZE ENTER] key. To change the paper size setting of another tray, repeat steps 2) to 4) after pressing the [START] key.

2) Insert a thickness gauge of 1.5mm to the three positions at 20mm and 130mm from the both ends of the developing doctor as shown.

3) Push the developing doctor in the arrow direction, and tighten the developing doctor fixing screw. (Perform the same procedure for the front and the rear frames.)

4) Check the clearance of the developing doctor. If it is within the specified range, then fix the doctor fixing screw with screw lock.

* When inserting a thickness gauge, be careful not to scratch the

developing doctor and the MG roller.

(2) MG roller main pole position adjustment

1) Remove and separate the waste toner box and put the developing unit on a flat surface.

2) Tie a string to a needle or a pin.

3) Hold the string and bring the needle close to the MG roller horizontally. (Do not use paper clip, which is too heavy to make a correct adjustment.) (Put the developing unit horizontally for this adjustment.)

4) Do not bring the needle into contact with the MG roller, but bring it to a position 2 or 3mm apar t from the MG roller. Mark the point on the MG roller which is on the extension line from the needle tip.

5) Measure the distance from the marking position to the top of the doctor plate of the developing unit to insure that it is 18mm. If the distance is not within the specified range, loosen the fixing screw A of the main pole adjustment plate, and move the adjustment plate in the arrow direction to adjust.

If the width (La) of the black background at the lead edge is equal that (Lb) at the rear edge, there is no need to execute the following procedures of 4) ~ 7).

La = Lb

6) Execute the main scanning direction (FR) distartion balance adjustment previously described in 2) again.

(4) Sub scanning direction (scanning direction) distortion

adjustment

When there is no skew copy in the mirror base scanning direction and there is no horizontal error (right angle to the scanning direction), the adjustment can be made by adjusting the No. 2/3 mirror base unit rail height. Before performing this adjustment, be sure to perform the horizontal image distortion adjustment in the laser scanner section. This adjustment must be performed in the following cases:

•When the mirror base wire is replaced.

•When the copy lamp unit or No. 2/3 mirror unit is replaced.

•When the mirror unit rail is replaced or moved.

•When a following copy is made.

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.

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.
