CAUTION

This copier machine 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 safety interlock switch is equipped.

Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

[1] GENERAL

1. Features of copying functions

(1) Various functions in the digital system

Different from the conventional analog copiers, the original image data scanned by the CCD sensor (which converts optical signals into electrical signals) are converted into digital signals. With the printer kit (option), in addition to copying functions, this machine can be connected with a computer to serve as a printer. The other features include the independent zooming function and black-white reversing function.

[5] UNPACKING AND

INSTALLATION

1. Use environment

To ensure safety and proper machine performance, please note the following before initial installation and whenever the machine is to be relocated.

(1) The copier should be installed near an accessible power outlet for

easy connection.

(4) Ensure that the area chosen for the machine location is level.

(5) Be sure to allow the required space around the machine for ser-

vicing and proper ventilation.

11-13/16" (30 cm)

(2) Be sure to connect the power cord only to a power outlet that

meets the specified voltage and current requirements. Also make certain the outlet is properly grounded. The outlet must be kept apart from appliances that consume much

power, such as large motors.

(3) Do not install the machine where it is:

• damp or humid,

• exposed to direct sunlight,

• extremely dusty,

• poorly ventilated,

• subject to extreme temperature or humidity changes (e.g., near

an air conditioner or heater).

23-5/8" (60 cm)

A small amount of ozone is produced within the copier during operation.

The emission level is insufficient to cause any health hazard.

NOTE:

The present recommended long term exposure limit for ozone is

0.1 ppm (0.2 mg/m3) calculated as an 8 hr. time-weighted average concentration. However, since the small amount that is emitted may have an objectionable odor, it is advisable to place the copier in a ventilated area.

Before setting the shading whiteboard correction value, make sure:

• Each of the 1st to 3rd mirrors is free from dust or contamination.

• The standard whiteboard is clean.

• The table glass is free from dust or contamination.

• The A3 or W letter size paper to be placed on the document table

is free from contamination, folds, or wrinkles.

Setting procedure:

1 Lay 10 sheets of A3 or W letter size paper one on top of another

on the document table, as shown in the illustration below. (Do not use recycled paper or color paper.) Use the white paper specified by Sharp.

Points to be kept in mind when carrying out shading correction

• Lay A3 or W letter size paper, aligning their edges with the rear

edge of the table glass and the OR guide L alignment position. (See the illustration.)

• When executing a simulation, do not hold down the A3 or W

letter size paper with the RADF.

How to stretch the mirror base wire (Check the following in advance.) Check the wire winding pulley stopping position. Check the wire winding pulleys (front/rear) have a wire groove in the

same position. (Visual checks) If the two wire grooves are much different in their level, loosen two set

screws securing the pulleys and align the position of the two wire winding pulleys (front/rear).

Tighten the two set screws securing the pulleys.

1 Hook the mirror base wire holder on the optical base hook. 2 Apply the mirror base B against the mirror base positioning plate.

Pass the front and rear mirror base wires through the outside grooves in the mirror base B pulley.

3 Pass the mirror base wires through the grooves in the paper feed

pulley.

4 Pass the mirror base wires under the mirror base B and wind them

on the winding pulleys. At this time, secure the wire groove of each winding pulley at its

upper position. Wind the mirror base wires 9 turns, with the 8th wind settled into the groove.

The copy lamp should be reinstalled as shown above, so that the copy lamp projection is located close to the R side.

against the drum surface and document surface.

1 Turn the mirror base drive pulley by hand to let the mirror base B

come in contact with the mirror base positioning plate. If both the front frame side and frame side of the mirror base B come in contact with the mirror base positioning plate simultaneously, it indicates that the mirror base B does not have proper parallelism.

ley. If La > Lb, turn the rear frame mirror base drive pulley in the

direction of A. (Do not move either of the flange or the mirror base drive shaft.)

If La < Lb, turn the rear frame mirror base drive pulley in the direction of B. (Do not move either of the flange or the mirror base drive shaft.)

5 Tighten the screw securing the mirror base drive pulley. 6 Repeat steps 1 to 3. 7 If La = Lb, carry out steps 4 and 5. (If La = Lb, adjustment is

over.) Repeat steps 1 to 6 until La = Lb.

Adjustment

1 Adjust by moving the mirror base B rail height up and down (in the

direction of indicated by the big arrow). If La > Lb, move the paper exit-side mirror base B rail upward by

half the difference between La and Lb. If La < Lb, move the paper exit-side mirror base B rail downward

by half the difference between Lb and La. Example: If La is 12 mm and Lb is 9 mm, move the paper exit-

side mirror base B rail 1.5 mm upward.

8 – 9

If Lc > Ld, move the paper feed-side mirror base B rail downward by half the difference between Lc and Ld.

If Lc < Ld, move the paper feed-side mirror base B rail upward by half the difference between Ld and Lc. (When moving the mirror base rail, hold the mirror base rail handle.)

2 Adjust the mirror base rail properly using step 1, so that La = Lb

and Lc = Ld.

3 After adjustment, turn the mirror base drive pulley by hand to

operate both the mirror bases A and B fully, to make sure that each mirror base does not interfere with other parts.

(Note): If the mirror base rail is moved extremely, the mirror bases

might interfere with other parts.
