Remarks: “Silicone Oil Type SS” P/No. A2579100 should be used.

CAUSE

One of the features of the new silicone oil is its (small amount of) low molecular “siloxane”. This has an effect on the volatility of the oil. At around 150 °C, the volatility of the new silicone oil is about 1/3 that of the previous silicone oil. This feature prevents the charge corona wire from getting soiled by the vaporized silicone oil. However, the lubrication properties of this new silicone oil are the same as those of the old type. For Cattleya, be sure to use the new type of silicone oil. The new silicone oil has been used from the first step of the development of Cattleya and therefore the machine is not designed to operate using the old type of oil. Consequently, it is impossible to predict the performance under the old type of oil (there are no tests on this available).

NOTE:

1. ”Siloxane” is the name of a chemical compound, which consists of silicon and oxygen.

2. The lubrication properties of a mix between the old and new oils would remain unaffected. However, the advantage of the new silicone oil over the older type is that the low volatility will be lost.

Interchangeability of the firmware

The main control firmware version 1.561 and scanner IPU firmware version 1.19 are not interchangeable with the older versions unless used as a set. They should be updated at the same time. When version 1.561 main firmware is used with the scanner firmware older than version 1.19, or when scanner firmware version 1.19 is used with the main firmware older than version 1.561, errors in machine operation may be expected.

Recommendation for machines produced before July

It is recommended that the firmware for machines manufactured before July 99 are updated to main firmware version 1.561 and scanner firmware version 1.19 at installation. This is because updating to these versions should be done at the same time. If this is not done, trouble may occur if main or scanner firmware update become necessary in the future.

Interchangeability of the main board and the scanner IPU board

The part numbers of the main board and the IPU board have been changed due to the firmware update to ver.1.561 and ver.1.19. (Please refer to MB No. MA257002.) The only difference between the new and old parts is the version of the firmware.

Because the new firmware is not interchangeable with the older versions, please check the version of the firmware and update as necessary when replacing the main control board or the scanner IPU board.

The positioning of the revolver unit is a critical check item when setting the drum unit in the upper drawer unit. To prevent any problems similar to the symptom described below, please release the following information to all technicians in your regions servicing this machine.

Problem

When the drum unit was set in the upper drawer un it, the devel opment unit was placed at 90 degrees (vertical), which is the development unit removal position. Being in this position, the drum came in direct contact with the ribs of the development unit upper cover, causing the drum to be scratched or damaged.

Action required

The above problem would normally happen at the time of installation or developer replacement. To prevent the drum from being damaged, the revolver unit must be set to its home position before the drum unit is set in the upper drawer unit.

Revolver Home Position

As shown in the following illustration, the magenta development roller should be positioned at an angle of 60 degrees (from horizontal). When rotating the revolver unit, you can see the cut-out [A] in the wheel, which locks the revolver unit in the home position.

Additional Information

In addition to the above information, please note the following remarks for when the revolver unit is set in the machine:

1. Revolver unit If the gears on the mainframe and revolver unit are not engaged firmly, this may result in a

gap between the revolver unit frame and copier frame (thus the unit will not be properly set). This also may cause the gears to be damaged when the revolver starts rotating. To ensure that the gears are properly engaged, it is necessary to manually fit (i.e. lock) the gears together by manipulating the revolver unit back and forth (slightly) as shown in the illustration (arrow [A]). This should be done while holding the toner hoppers.

2. Drum unit To ensure that the gears between the drum and drum shaft properly engage, the flange [B]

of the OPC drum must be pushed toward the back of the machine. (This is explained on S/M page 6-11.)

Since the vibration generated from the image transfer belt drive section is transmitted to the drum section, this vibration may interfere with drum rotation if the gears are not properly engaged. This causes banding on the image (at 1.7 mm intervals).

SYMPTOM

Dirty or colored background appears in the area near the leading edge. A slightly pale image or normal ima ge appears in the other areas towards the trailing edge. (The width of the area with this dirty or colored background varies.)

CAUSE

The development bias terminal is pushed against the development input shaft by a spring to ensure proper terminal contact when the development unit reaches the copying position. When the terminal does not move smoothly, poor contact of the development bias terminal results at the beginning of development of the latent image (dirty background will occur under these conditions). When the contact between the terminal and the development input shaft is not as poor, the image becomes slightly pale (or normal if contact is good).

PAGE: 2/2

ACTION

Pull out the revolver/drum drawer and clean the development bias terminal.

Turn the terminal counterclockwise then clockwise (more than ten turns each). Push the terminal repeatedly more than ten times so that terminal movement is smooth.

Reassemble the machine and check the copy quality. If the above action is not successful (this is a very rare case), replace the development

bias terminal with a new one (P/N A2573298).

If the new part is not available, loosen the upper screw that secures the development bias terminal to the copier rear side frame.

- Objective Machines -

The development bias terminal was previously modified from a one-screw type to a two-screw type, effective from around May, 1999.

If the two-screw type terminal is secured too tightly, a slight deformation of the terminal casing can occur. The machines in the field that could potentially exhibit this problem were produced from May to July, 1999, because the bias terminal was not inspected in these machines.

However, the occurrence rate is expected to be very low.

Countermeasure for machines in mass-production:

The bias terminals have been inspected at the factory since August, 1999. To ensure proper contact between the bias terminal and the development input shaft without the inspection, a modification of the development bias terminal has been applied to the production line from October, 1999 (the inner diameter of the terminal casing has been slightly increased). The part number has been changed from A2573297 to A2573298.

SYMPTOM

The following only occurs in thick paper mode and OHP mode.

A horizontal line appears at 106 mm from the leading edge. The line is normally colored Black but the last one of the multiple copy run is colored Magenta (in the Full Color mode).

CAUSE

When the drum speed is slowed in thick pape r/OHP mode, loose screws that fasten the flywheel supporter to the drum shaft cause the drum to stop for a very short while.

ACTION

Remove the large and small flywheels and tighten the screws for the flywheel supporter. (Refer to the illustration on the next page.)

The flywheel supporter has four cut-outs for the screws. Two out of the four cut-outs have a flat surface (from May production: the cut-in serial numbers were not controlled). Make sure that the screws are positioned on these flat surfaces, especially after disassembling these areas.

CAUSE

The timing belt that drives the paper transfer belt disengages from the cogs of the timing pulley (jumping one cog over) when the movement of the tension roller bracket becomes a little worse. It has been found that the tension spring for the timing belt does not have enough strength to prevent this random jitter.

Notes for when removing the toner cartridge without toner end indication

If the toner cartridge (which is not empty) is removed from the toner cartridge replacement position, the cartridge lever may not turn smoothly when reinstalling the toner cartridge. If the cartridge lever is not completely turned to its lock position, toner may scatter from the toner hopper.

To prevent the above possibility, follow the following procedure:

1. Remove the revolver cover.

2. Rotate the revolver unit until the cartridge you wish to remove is in the removal position (lower left, looking from the front). See the illustration below.

Note:

If the Cyan cartridge is removed in this position, it is possible to reinstall the
