Read This First

A few simple symbols and notations are used to help you read faster and find the information you need. Before you use this guide, glance over this list of special notations and be sure you understand what they mean.

NOTE

Information under this heading describes helpful hints, restrictions, and how to avoid difficulties.

CAUTION Failure to pay attention to CAUTION notices can

result in damage to the equipment.

WARNING

Warnings are for your safety. Failure to pay attention to WARNING information can be dangerous to you and others.

IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged.

2. The wall outlet should be near the copier and easily accessible.

3. Note that some components of the copier are supplied with electrical voltage even if the main switch is turned off.

4. If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

5. The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

1. Never operate the copier without the ozone filter installed.

2. Always replace the ozone filter with the specified one at the specified interval.

3. Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.

2. The main control board has a lithium battery which can explode if handled incorrectly. Do not replace the battery. Do not recharge, or burn this battery. Used batteries must be handled in accordance with local regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Do not incinerate the toner cartridge or the used toner. Toner dust may ignite suddenly when exposed to open flame.

2. Dispose of used toner, developer, and organic photoconductors according to local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

4. When keeping used lithium batteries (main control boards) in order to dispose of them later, do not put more than 100 batteries (main control boards) per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

Machine Operation Check 1 July 1994

1.3.3 Copy quality check CAUTION Before checking copy image quality, check the toner density control data in the

service tool [4-02] screen. Perform setting C if the data is not correct. Also, check the AID reference voltage in the [4-03] screen using the PC-1 chart. Perform setting A if the value is not correct. (If the AID reference voltage is within the standard, you do not have to perform setting A.)

To check the copy image quality and paper transportation in the copier, make some copies in the platen cover (no ADF and SADF) and AID (Auto Image Density) modes using a test chart.

2. Follow the steps below to complete the image quality adjustment. (Refer to the following

page for the standards.)

1) Position a test chart on the exposure glass. Make copies to check the side-to-side registration. Adjust it by changing the paper tray position, if necessary. Repeat this step for all paper trays.

2) Select the paper tray which has the largest paper size.

3) Access the service tool and select the [5-02] screen. Check and adjust all items in that screen.

4) Leave the service tool, and select the paper tray which has another paper size.

5) Again, check and adjust the erase margin and duplex side fences width on the [5-02] screen. Repeat this step for each paper size which will be used by the customer.

6) To check and adjust the side-to-side registration of the back side of the copy, make copies in the duplex mode.

7) Remove the test chart from the exposure glass and insert an original in the SADF. Make copies to check and adjust the leading edge and side-to-side registration in the SADF mode.

8) Place some originals in the ADF. Make copies to check and adjust the side-to-side registration in the ADF mode.

CAUTION

a) The side-to-side registration must be checked for all paper trays. b) The erase margin and duplex side fence width must be checked for all paper sizes. c) If the erase margin is not sufficient, thin black lines may sometimes appear on

copies (especially on the side edges of copies in the ADF mode). This is because the side-to-side registration varies slightly on each copy if an operator does not set the original side guides securely. You have to make more than 10 copies and check that all of them are within specifications after the adjustment.

d) Check the side-to-side registration of the back side of the copy in the duplex mode before installing the peripherals. If the value is outside specifications, you have to remove the copier right cover.

Put about 20 originals on the ADF and make one set of copies in the single original duplex mode. Repeat this procedure for all paper trays.

4. Put about 100 originals on the ADF and make one set of copies in the 2-sided original du-

plex mode.

5. Insert an original in SADF and check that copying is normal.

6. If peripherals are installed, check that they works properly.

User Guidance Items 1 July 1994

1.5 User Guidance Items

This section contains important information regarding efficient operation of the machine.

1.5.1 Guidance items prior to the installation

Items requiring user approval after explanation. This has to be done before machine installation.

Paper to use

1. We recommend using neutral paper as copy paper to prevent abnormal images. Some acid

papers contain talc, and this white powder will appear on the OPC surface as spots. This causes abnormal copies, which have dirty spots on the background.

2. We recommend using lengthwise grain in all cases to prevent creased copies.

How the original influences copy images

1. In patched originals, shadows around the patched part appear on copies as black lines.

2. In OHP originals, drawn pictures and characters are copied double.

Smoothing original curls

To avoid transport trouble, advise users to correct large curls before setting the original. Refer to the illustrations and information given below.

Face curl (3 mm or less) No curl is acceptable for thick originals of 65 g/m

Back curl (10 mm or less)

The original cannot be transported if it curls (face curl).

or heavier.

2. The original cannot be transported if it curls down (back curl) 10 mm or more.

Original to use

There are some types of paper that should not to be used as originals with the ADF. The following are some examples:

1. Dog-eared, torn, or creased paper

2. Coated paper (carbon paper, thermal paper, etc.)

3. Curled paper

4. Originals that are glued or taped

1-18

1 July 1994 User Guidance Items

5. Translucent paper (including OHP)

NOTE

The above types of paper may be used as an original in the SADF mode.

6. Damp paper

7. Bound originals

8. Paper that is thicker or thinner than specified for this machine

Originals that have holes as shown cannot be used in the ADF mode.

A: No holes are allowed on the leading

edge. (To prevent multifeeding.)

B: No holes are allowed in these areas.

(The recycle arm may be caught in the holes.)

C: Holes larger than 6 mm in diameter are

not allowed on the trailing edge.

D: Holes larger than 10 mm in diameter are

not allowed in the center. (To prevent sensor’s misdetection.) This type of paper cannot be used in the SADF mode either.

[Leading edge]

100 mm

10 mm

50 mm

Paper replenishment

When the 2nd or 3rd paper tray runs out of paper and the indication Add paper lights in red, this means there are still about 50 sheets of paper left in the tray.

Fusing oil

The pick-off pawls of the fusing unit sometimes make slight oil marks on the leading edge of copies .

Copy image area

1. The blank range is provided as shown to prevent

original shadows on copies.

2. Damp copy paper will have an 8 mm blank margin

(or less) at the trailing edge of the front side, and if duplex copying, the back side will have a blank margin of 10 mm (or less) at the trailing edge.

Total of left and right should be 7 mm or less.

1-19

User Guidance Items 1 July 1994

1.5.2 Additional guidance items

Explain the following if the user is unfamiliar with the subject items.

Stacking duplex copies

When a large number of duplex copies (100 copies or more) are produced, we recommend using the finisher so they are stacked in the shift tray because toner from the stacked copies on the copier’s copy tray may be deposited by heat.

How the main switch is used

The ozone exhaust fans and transport vacuum fan continue to operate when the main switch is OFF to discharge air from the machine. This prevents image deterioration on the OPC caused by fumes, which is produced by the corona discharge. Also, heaters turn on when the main switch is OFF and prevent condensation on the mirror and lens and damp paper in trays. Advise users never to pull out the power plug or shut off power from the source. Tell them to use the main switch to power off.

Toner cartridge replacement

Used toner is collected in the toner cartridge and is never used again because it cannot be used for copying. Direct users about the following points.

1. Never pull the shutter again after the cartridge is set. If the shutter is pulled, the collected

toner is used again.

2. Firmly pull the vinyl sheet on the shutter when installing a new cartridge. If not, only about

half the amount of toner in the cartridge will fall to the development unit. This may cause a used toner blockage on the way from the cleaning unit.

Loading paper

When loading paper in the paper trays, do not exceed the load limit. It is indicated by a decal. If paper is excessively loaded, the top of the paper stack may hit the pick-up roller and damage it when the paper tray is set.

Loading original

When loading paper on the original table of the ADF, keep the maximum capacity (40 sheets for A3 or 11" x 17" original and 80 sheets for the other sizes original). The load limit is indicated by a decal. If originals are excessively set in the ADF, original misfeeding or multifeeding may occur because of the original separation system. The air knife cannot separate the originals when weight of the original stack is too heavy.
