J2SS-C3

(Machine Code: B047/B048)

Service Manual

– Insert Version –

The B047/B048 machines are based on the A163/A251/A252 copiers. Only the differences from the base copier are described in the following pages.

Therefore, this documentation should be treated as an insert version of the base copier’s service manual. It should always be utilized together with the base copier’s service manual.

INSERTION PROCEDURE OF SERVICE MANUAL

1. Replace the book spine tag with the new one.

2. Insert the B047/B048 service manual a fter the A1 63/A 25 1/A252 manual.

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 and the peripherals 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.

6. The copier is not attached to the table. Pushing the copier too hard may cause it to drop onto the floor. While moving the copier, push the table.

7. When the main switch is turned on, the machine will suddenly start turning to perform the developer initialization. Keep hands away from any mechanical and electrical components during this period.

HEALTH SAFETY CONDITIONS

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

2. Always replace the ozone filters with the specified ones at the specified intervals.

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.

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.

NOTE: For clarity’s sake, the following description will ref er to the paper’s edges

as edge [A] (furthest edge from the operator) and edge [B] (closest to the operator).

Original Positioning

In the B048 copier, edge [A] of the original is placed onto the original table. This activates the original entrance sensor [C].

The main motor turns the original entrance rollers [D]. The quenching lamp, development bias and PTL also turn on.

For proper feeding (especially for a thin original), the original entrance rollers rotate backwards (feeding towards the operator) for 300 ms. This ensures that the original is gripped firmly by both of the original entrance rollers [D], feeding it evenly.

2-1

EXPOSURE 11 May, 2001

4 seconds after the sensor is activated, the original feed motor starts rotating. This delay gives the user time to align edge [A] against the original entrance rollers [D]. This helps prevent skew.

The original is fed through the machine to the scanning start position [E]. This machine scans the original backwards, starting with edge [B] and scanning towards edge [A]. The original is now ready to scan.

Scanning

The original is scanned, moving back towards the operator. When edge [ A] activates the original registration sensor [F], the roll paper feed

motor turns on. Copy paper begins to feed, and the registration clutch is activated. When edge [B] reaches the original feed start posi tion [E] (26 mm ahead of the

original registration sensor [F]), the original feed motor stops to wait for the copy paper.

In the copy section, the registration clutch turns off once the copy paper’s leading edge is 10 mm past the registration sensor [H]. The voltage is now applied to the charge coro na.

The original feed motor begins rotating towards the operator again at 60 mm/s, and the original is delivered to the exposure glass. Light from the exposure lamp [M] is reflected off the paper to the fiber optics array [L].

Once the original’s edge [B] passes the original entrance sensor, the registration clutch and roll paper feed motor turn on agai n. The pap er feed res ume s and the copy paper is transported to the drum [I].

To measure the original length for cutting, the copier’s CPU measures the time from when the original registration sensor detects edge [A] until the original entrance sensor detects edge [B].

The copy paper length is measured by counting the number of steps as the roll paper feed motor (a stepper motor) turns. Just before the paper is cut, the feed motor speed doubles. This creates a buckle at the trailing edge of the copy paper. The feed motor then stops as the cutter unit cuts the paper. Copying, however, continues. The buckle provides the necessary slack while cutting.

When making duplicate copies, the original feed motor pauses, then changes directions again, and the original is fed back to the scanning position 200 mm/s. Once previous paper exits out of the roll feeder, the roll paper feed starts as well, and the process repeats.

After all copies are made, the original is delivered to the original table. If original hold mode is enabled (SP16), the original will stop with edge [A] caught by the original entrance rollers. The original can be fed out by pressing the ! key. If original hold mode is not enabled, the original feeds out completely, and is not caught.

Start Key Enable

When the start key enabled (SP34) is set, the start key acts as a starting trigger. In this mode, when the original activates the original registration sensor, edge [B] is delivered to the original registration sensor position. Everything pauses until the user presses the start key. Original feed and paper feed then resume.

Recovery from Toner End Condition

After replacing the toner cartridge (opening and closing the original feed unit), the main motor rotates the development unit for 60 seconds. During the first 30 seconds, toner is supplied at 100% of the supply amount until TS level reaches 3. The main motor continues to rotate the development unit for another 30 seconds. Then copies can be made.

If the TS level does not reach 3, the CPU stops the machine and displays the toner end condition. This prevents the operator from resetting the toner end condition by simply opening and closing original feed unit.

B047D101.WMF

B047/B048 copiers have a used toner overflow sensor [A] and a used toner cover switch [B].

When the used toner overflow sensor detects that the used toner tank is full, the overflow indicator begins blinking on the operation panel. 30 more meters (A1/D size: 50 copies, SP51) can be copied. After that, the used toner overflow indicator stays ON, and the machine will not operate.

The used toner cover switch detects when the used toner cover is open. “Door open” is displayed on the operation panel, and the start key is disabled.

2.8.1 OVERVIEW

[A]

Detailed

Descriptions

B047D102.WMF

Two thermofuses [A] (184°C, 192°C) keep the fusing unit from overheati ng . Two thin-film thermistors measure the hot roller and pressure roller’s temperature. The hot roller is a thin-shell, Teflon coated roller. The thinne r roller allows a much-

shorter warm-up time. However, extra care should be taken while working around the hot roller. It is very easy to damage.

Like the A163/A251/A252 copiers, if the fusing temperature is lower than 60°C when the main switch is turned on, the machine assumes that it has not been used recently, and the main motor must rotate to generate the necessary triboelectric charge on the toner and developer.

In the A163/A251/A252 copiers, the main motor begins rotating immediately. However, the B047/B048 copiers have a thin shell hot roller and a contact thermistor. When cold, the thermistor is hard and might damage the roller. The machine waits until the hot roller temperature reaches 80°C. At that temperature the thermistor softens and the hot roller can rotate safely.

Except for the differences listed above, the B047/B048 copiers are identical to the A251 and A252 copiers. Please refer to A163/A251/A252 copier service manual for additional details.

CAUTION

1. Unplug the main machine’s power cord before starting the following procedure.

2. Before starting the installation, make sure the machine is level.

3. The copier is very heavy (85 kg, 187 lbs). To avoid serious injury, make sure that you have a sufficient number of people to assist you. It takes at least two people to lift the copier safely.

4. Please be careful not to get your hand caught under the copier as you place the copier onto the roll feeder.

1. Lower the feet [A] (4 feet) so that the roll feeder [B] does not move while the copier [C] is being installed.

CAUTION Do not open the paper tray until the copier is placed on top of the roll feeder. The paper tray drawer is very heavy. Without the copier weight to hold it down, the roll feeder will fall over. The tray is shipped with a safety latch holding the drawer shut.

Sets the process for toner end recovery. When set to the default value, the toner density is checked as described in the Toner Density Control section 2.4.2. Forced recovery skips this testing procedure, and just clears the toner end condition.

The fusing section’s transport speed is slightly faster than the roll feeder’s. This is done to stretch the copy paper. However, due to over-stretching, creases may develop along the trailing edge when the copy paper is longer than 1,200 mm. To prevent this, the roll feeder’s speed is increased slightly every second once the paper feed length exceeds 1,200 mm. The speed is changed 5 times.

Normally the copy process stops at the trailing edge of paper or original which ever comes first. If this mode is selected, copy process continues to the copy’s trailing edge even if the original trailing edge comes first. Use this mode to combine several originals onto a single copy.

Normally, an original cannot be inserted into the rear feeder while in Synchro-cut mode. If 1 is selected, an original can be inserted from the rear side even if Synchro-cut mode is used. This cannot be used with the trailing edge margin function. In this mode, the copy will be about 200 mm longer than the original (B048 copier only).

For the 2nd copy, it is not necessary to press the cut key at the trailing edge of the original. Also, before the 2nd original is inserted, the cut length in the cut length counter can be changed using the “+”/“–” keys.

It can also be set to start after the trailing edge passes the original entrance sensor. The default value provides a faster first copy and increases 1 to 1 CPM. If the emergency stop key is pressed while the original is being transported to the scanning start position, copy paper is cut and fed out of the copier. Whichever setting is selected, the first copy and 1 to 1 CPM are within specification.

Select whether the origin al is transported from the original table to the scanning start position directly, or whether the original is returned to the scanning start position after the trailing edge of the original passes through the original registration sensor (B048 copier only).
