SECTION 4

SERVICE TABLES

1. SERVICE REMARKS

1.1 GENERAL CAUTION

1. To prevent physical injury, keep hands away from the mechanical drive components when the main switch is on (especially during the warm-up cycle). If the Start key is pressed before the copier finishes the warm-up cycle, (Start indicator starts blinking) the copier starts making copies as soon as the warm-up cycle is completed.

2. When the development unit, cleaning unit, drum unit or the DF is removed from the machine, the upper unit becomes lighter. If the upper unit is released under this condition, it tends to open very abruptly. The service engineer might be injured if he is leaning over the machine at this time. Also, the machine might move due to the shock of the upper unit opening abruptly. To avoid possible injury or machine damage, hold the upper unit firmly when opening the unloaded upper unit.

3. Even with the above mentioned components installed the upper unit can open rather rapidly. Due to this possibility it is important to always hold the upper unit with one hand when releasing it from the lower unit. It is also important that the operator also be familiar with the proper method of releasing the upper unit. This condition is not a concern if the DF is installed to the FT3213.

4. Due to variation in the tolerance of the torsion springs, the upper unit cannot hold at an angle of 16 degrees by itself when the DF is installed. To avoid possible injury, always use the upper unit stand to keep the upper unit open.

1.2 DRUM

The organic photoconductor drum is comparatively more sensitive to light and ammonia gas than a selenium drum.

1. Never expose the drum to direct sunlight.

2. Never expose the drum to direct light of more than 1,000 Lux for more than a minute.

3. Never touch the drum surface with bare hands. When the drum surface is touched with a finger or becomes dirty, wipe with a dry cloth or clean with wet cotton. Wipe with a dry cloth after cleaning with wet cotton.

4. Never use alcohol to clean the drum. Alcohol dissolves the drum surface.

5. Store the drum in a cool, dry place away from heat.

6. Take care not to scratch the drum as the drum layer is thin and can be damaged.

FT3013/3213 4-1 FSM

7. Never expose the drum to corrosive gases such as ammonia gas.

8. Always keep the drum in the protective sheet when inserting or pulling the drum unit out of the copier to avoid exposing it to bright light or direct sunlight. This will protect the drum from light fatigue.

9. Before pulling out the drum unit, place a sheet of paper under the unit to catch any spilled toner.

10. When installing a new drum, do the following: a) Apply setting powder to the entire surface of the drum.

b) Perform the drum initial setting (SP66). NOTE: This is not necessary at installation of a new machine as the

drum initial setting is performed at the factory.

c) Perform the Vsg adjustment (SP54).

11. Dispose of used drums according to local regulations.

1.3 CHARGE CORONA

1. Clean the corona wire by sliding the corona unit in and out. (The cleaner pads come into contact with the corona wire when the corona unit is slid all the way out.) The wire and casing can also be cleaned with water or dry cloth. Do not use any abrasives or solvents.

2. Do not touch the corona wire and the grid plate with oily hands. Oil stains may cause uneven image density on copies.

3. Make sure that the corona wire is correctly positioned between the cleaner pads and that there is no foreign material on the casing.

4. When adjusting the charge corona current, always make sure that the center of the drum shoe is aligned with the middle of the corona wires.

5. Clean the charge grid with a blower brush (not with a cloth).

6. The corona height should only be adjusted in the following two cases: a) When the front end block is replaced

b) When the drum charge current is uneven

FSM 4-2 FT3013/3213

1.4 OPTICS

1. The position of following parts are very difficult to adjust. Do not adjust them. a) 4th/5th Mirror Home Position Sensor

b) Lens Home Position Sensor c) Lens and 4th/5th Mirror Guide Rails

NOTE: Before removing a sensor bracket to replace a sensor, mark the

position of the bracket. Check the copy image (magnification and focus)to confirm that the sensor bracket has been properly repositioned.

2. Clean the exposure glass with glass cleaner and a dry cloth to reduce the amount of static electricity on the glass surface.

3. When reinstalling the exposure glass, make sure that the red mark on the edge of the glass is positioned on the right hand side facing upward. This side has received a special treatment to make it smoother and generate less static electricity. This is especially important when the DF is installed.

4. Clean the following parts with a dry cloth: a) Lens and 4th/5th Mirror Guide Rails

b) Scanner Guide Plates

5. Only use a clean soft cloth damped with alcohol or water to clean the mirrors and lens.

6. Do not touch the following parts with your bare hands: a) Reflectors

b) Exposure Lamp c) Mirrors and Lens

7. Whenever one of the actions listed below needs to be performed, all the following actions must be done in order. a) Optics cleaning

b) SP95 (VL Correction Reset) c) SP48 (Light Intensity Adjustment) d) SP56 (ADS Reference Voltage Adjustment)

8. Do not adjust VR401 on the AC drive board.

FT3013/3213 4-3 FSM

1.5 DEVELOPMENT

1. Be careful not to nick or scratch the development roller sleeve.

2. Place the development unit on a sheet of paper after removing it from the copier. This prevents any small metal objects (staples, paper clips, E-rings, etc.) from being attracted to the development roller and getting inside the unit.

3. Never loosen the two screws securing the bias terminal block. The position of the terminal block is set with a special tool and instrument at the factory to ensure the proper gap between the drum and the development roller.

4. Never loosen the three screws securing the doctor plate and the four screws securing the doctor plate mounting bracket. The position of the doctor plate is set with a special tool at the factory to ensure the proper gap between the doctor blade and the development roller.

5. Clean the drive gears after removing used developer.

6. Developer initial setting (SP65) is necessary when the developer is replaced.

7. Dispose of used developer according to local regulations.
