CAUTION

This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot damage to the retina. The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts.

2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical system.

4) The middle frame contains the safety interlock switch. Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

Warning!

This product is a class A product. If it is operated in households, offices or similar surroundings, it can produce radio interferences at other appliances, so that the user has to take adequate countermeasures.

• There must be no other sheet than the black chart on the glass sur-

face.

• Especially when in SPF scan, the center area is scanned in the main

scan direction. Be careful to prevent external light from entering the scan area.

3) Check that the lead edge is not shifted. (Both surfaces)

Place only the black chart on the OC glass.

rescent lamp, etc.

Outline of SIM: The optical unit is shifted to recognize the boundary between the OC glass and the SPF glass cover. With the same position as the reference, the SPF scan position is automatically adjusted.

(If the original lead edge adjustment has been made properly, even when the scan position is shifted, it is followed automatically.)

For the SPF standard-provision machine, check that the black chart covers the SPF glass.

Placing the black chart The black chart must cover this area.

C. Image density (exposure) adjustment

(1) Copy mode (SIM46-2)

1) Set a test chart (UKOG-0162FCZZ) on the OC table as shown below.

Rear

Front

2) Place three or more sheets of A3 (11" x 17") paper on the test chart.

3) Execute SIM 46-2.

4) After warm-up, shading is performed and the current set value of the density (exposure) level is displayed on the display section in 2 digits.

For mode selection, use the [10-key].

5) Change the set value with the [10-key] to adjust the copy image density.

6) Make a copy and check that the specification below is satisfied.

Note: Place originals in the rear reference, and the test chart in the

front reference when adjusting the exposure.

4) Change the adjustment value of the SPF scan end position. (Change the adjustment value of SIM50-6-3 from 50 to 36.)

Change the number of steps for Pin off – scan end position from 1,014 to 986. Be sure to execute this adjustment because an image may be cut off during FAX transmission though copying is normally performed.

5) Change the initial value of the SPF exposure adjustment (SIM46-

20) from 50 to 53. (For the CCD exposure adjustment with SPF, use the value of the OC adjustment value +3.) There are suffixes of –1 SPF and –2 SPF. Change each of them.
