TOPIC:


CONTENT OF CHANGES:

Fan control optimization. The right side fan (for PWB cooling) is not stopped at Sleep. - Therefore, this is corrected.

Corrective measures for the drum ghost image due to residing potential. Change for the main charge adjustment: The primary transfer current is adjusted in conjunction with the MC setting of 1 to 5 in the service menu.

KMKR support. The optional language of Korean is added.

KMTW support. The optional language of Traditional Chinese is added.

Corrective measures for the color shift due to cleaning failure at the calibration. The color shift may occur if cleaning failure occurs with the color adjustment reference pattern on the primary transfer belt. - Therefore, this is corrected.

Change: Cleaning bias to the cleaning fur brush at the calibration is changed from 2A to 8A.

Toner consumption optimization. The drum protection control is reviewed and its control table is changed to optimize the toner disposal at the normal operating environment. After the above change of the drum protection control table, conductive compound may adhere at the gap between the main charger roller and the drum and white streaks in the drum circle interval if the machine is left 2 hours or more at high temperature and high humidity. Therefore, preventive control for the white streaks is implemented.

TB 12 / Display message Close rear cover 1 2KT-C238/M Date: 18-02-2013

TOPIC:

In rare case, the message The cover is opened is displayed by misdetection of REAR COVER opening when slowly closing TOP COVER while REAR COVER is closed. Thus, the shape of LEVER INTERLOCK is partly changed for improving its motion for switching the detection switch of REAR COVER opening/closing.

CONTENT OF CHANGES:

Depending on the location of the rear edge of LEVER INTERLOCK against the protrusion of REAR COVER and on how to close TOP COVER, the rear edge may get under the protrusion of REAR COVER, and as a result, the front side cannot press down the detection switch of REAR COVER opening/closing due to the upward rotation failure of LEVER. Thus, the rib is added to the rear edge of LEVER for securing the margin against its inroad.

TB 13 / Change for the toner container shutter 2KT-C238/M Date: 19-02-2013

PHENOMENON:

The operation fully opening the top tray is tough. And so, HINGE LID R/L at the fulcrum parts of the top tray may be damaged in rare case if pushing up the top tray forcibly to fully open it. (HINGEs damage is applied to a part of CDC 1626, CDC 1726 / DCC 2626, DCC 2726 only. Refer to the serial number table in page 3.)

CAUSE:

The operation fully opening the top tray becomes tough due to the load that occurs when the joint X engaging with the cam Y switching the toner container's shutter is rotated and trusted by RATCHET SHUTTER (No.1) that rotates and thrusts the joint X in the main machine towards the machine right and left direction by interlocking with the top tray's opening/closing operation.

CONTENT OF CHANGES:

1.) The shape of RATCHET SHUTTER (No.1) is changed to smooth the rotation/thrust operation of the joint X in the machine side when fully opening the top tray. 2.) The material of HINGE LID R/L has been changed for improving the toughness on the way of the production of CDC 1626, CDC 1726 / DCC 2626, DCC 2726.

(Later CDC 1626, CDC 1726 / DCC 2626, DCC 2726 than the serial number in the table in page 3 has been already changed, and the other models have been changed since the 1st production.).

TB 14 / Paper feed jam at the 250-sheet cassette 2KT-D027/M Date: 06-03-2013

TOPIC:

Depending on the backlash to the cassette length direction, the 250-sheet cassette is incompletely inserted into the machine but the cassette feed drive can be driven (The bottom plate is lifted up when feeding the paper from the cassette). STOPPER HOOOK at the cassette rear side may hook the lever holding the paper (X in the figure below) at the machine inside at their contact faces in the above state, and STOPPER HOOK does not rotate under its own weight while the bottom plate is lifted up to feed the paper, and the lever (X) cannot return and continues to hold the paper, and so, the no paper feed jam (JAM0501) may occur.

CONTENT OF CHANGES:

The shape of STOPPER HOOK (No.1) is changed and SPRING STOPPER HOOK (N) is added to improve the operability of STOPPER HOOK when feeding the paper from the cassette with the bottom plate lifted up.

Normal state State when the phenomenon occurs

250-sheet cassette

Insert

Bottom plate

When the bottom plate is lifted up by the cassette feed drive, the lever (X) returns for distancing from the cassette after STOPPER rotates under its own weight, and then the cassette paper feed starts.

STOPPER doesnt rotate since it is hooked at the contact faces after the bottom plate is lifted up, and the lever (X) cannot return. As a result, no paper feed jam (JAM0501) occurs.

TB 15 / Toner supply failure 2KT-D022/M Date: 07-03-2013

TOPIC:

When the joint (X) at the machine left side insufficiently engages the joint (Y) at the toner container due to dimensional variation of the parts or the assembly, the machine drive may not be transmitted to the toner container and the toner supply may fail. And, the toner replacement message may frequently appear even if the toner container is replaced with the new one. Thus, the following is changed.

CONTENT OF CHANGES:

The shape of CAM TONNER SUPPLY (No.1), that thrusts the joint at the main machine in the engaging and disengaging directions, is changed to facilitate the joints engagement of the main machine and the toner container.

TB 18 / The color registration drift due to coming off 2KW-D096/M Date: 28-05-2013

TOPIC:

Please note the following when detaching the Bk drum unit because the ID sensor shutter may come off depending on the way to detach the Bk drum unit (Note 1). In a rare case, it causes the color registration drift if the main machine continues drive while the ID sensor shutter comes off.

NOTE:

When detaching the Bk drum unit, please hold the both sides of that unit, and pull it frontward along the guide rails inside the machine.

If the ID sensor shutter comes off and cannot slide, it covers the ID sensor even if the top tray is closed. Then, acquiring the correction fails because the ID sensor covered cannot scan patch patterns drawn on the transfer belt at the color registration executed when turning on the main power, etc. (Note 2) As a result, the color registration is executed based on the correction that was normally acquired last time, the difference with the actual state of the machine is widened per the execution of the color registration and the color registration drift gradually appears.

Note 1: The ID sensor shutter may come off due to contact of the Bk drum unit if detaching the Bk drum unit in the order of right and left side. (Normally, it is recovered by pressure of the transfer belt unit from upside when reattaching the transfer belt unit. If detaching the Bk drum unit in the order of right and left side, to make sure, please confirm the ID sensor shutter's sliding motion by opening and closing of the top tray after closing the RFID holder, and recover it if necessary.)

Note 2: If acquiring the correction fails when executing the color registration, the error message does not appear. While the failure or success of the acquirement can be checked by referring to the numeric (Refer to the figures in the next page) of the calibration result on the 2nd page of the maintenance report (for MFP) or the service status page (for Printer). ("00" means the success and other numeric means the failure.)

Press down the ID sensor shutter (X in the figure below) inside the BK drum unit by hand, and correct the ID sensor shutter dislocation or come-off. After that, close and open the top tray at the state of closing the RFID holder to check if the ID sensor shutter can be slide horizontally.

If the ID sensor shutter comes off and cannot slide, it covers the ID sensor even if the top tray is closed. Then, acquiring the correction fails because the ID sensor covered cannot scan patch patterns drawn on the transfer belt at the color registration executed when turning on the main power, etc. (Note 2) As a result, the color registration is executed based on the correction that was normally acquired last time, the difference with the actual state of the machine is widened per the execution of the color registration and the color registration drift gradually appears.

Step 4 - Check of the auto color registration, Replacement of the intermediate transfer unit- ( Rev.: 1)

When the color registration shift appears again after passing several days since executing Step 1, 2 and 3, check whether the auto color registration is normally executed or not with the following procedures. Refer to Check of the auto color registration below. If it failed as a result, replace the intermediate transfer unit with the new one because it may cause degradation over time of the transfer belt. Refer to Intermediate transfer unit for replacement below.

Check of the auto color registration 1.) Start up the main machine to switch its READY mode. 2.) Turn the main power off, and open the rear cover. 3.) Press the inter-lock switch at the rear left side of the machine by using a flat-blade screwdriver. (Fig.25) 4.) Turn the main power on. (The machine drive is started.) 5.) Judge whether the auto color registration is normally executed or not. (Fig.26, 27)

Normal: The color registration patches appear at the horizontal both sides of the transfer belt one time, and then the machine drive stops.

Failure: The color registration patches appear at the horizontal both sides of the transfer belt two times, and then the machine drive stops. The intermediate transfer unit should be replaced with the new one.

Corrective measures for the MP feed clutch motion error (J0509)

TOPIC:

Depending on variation of the MP feed clutch, in rare case, the inner parts of the MP feed clutch might be unevenly worn out in a long period use and the MP feed clutch might idle. When idling, the MP feed roller does not rotate and it causes no paper feed from the MP tray (JAM0509). Thus, the inner structure of the MP feed clutch is changed.

(Machine left side without the outer covers)

PROCEDURES:

1) Detach the paper feed drive unit (No.1) from the main unit. Refer to Disassembly and refit in Service Manual for details.2) Put the paper feed drive unit on the work space

such as Fig.1 (motor is located at left side of the service person), and release four hooks. (Fig.1) Divide the unit up and down like being opened, and replace the MP feed clutch (No.2). (Fig.2) Note: Don't move the lower divided unit facing the work space to prevent the parts from falling after divided. Reattach the bushing at 4 parts inside the upper divided unit if they fall.

Distinction between the old and new MP feed clutch

The color of the rating label affixed on the field core of the MP feed clutch is changed from blue to light green.

3) Cover the upper divided unit onto the lower divided unit and secure them by four hooks. At that time, adjust the clutch's direction so that the terminals of each clutch fit into the hole of the upper divided unit. (Fig.3)

4) Check the operation of the following parts after

reassembling the paper feed drive unit. If not correctly operating, reassemble the unit again. Gear B is rotated according to rotating Gear A. Gear group D is rotated according to Gear C. Shaft E is relocated after pressed.

5) Reattach the paper feed drive unit in the main unit by reverse procedures.

Firmware Upgrade (Upgrade Pack V 8.00N)

TOPIC:

The firmware is upgraded as follows. CONTENT OF CHANGES:

Corrective measures for the confirmation display of wrong detection of the waste toner box. The state of the waste toner box might not be recognized due to misalignment in software during the interrupting procession when the machine recovers from the sleep mode, and the improper display instructing to check the state might appear even if the waste toner box is not full. Thus, this is corrected. The above wrong state is also cleared only by turning the main switch off and on, but not cleared by detaching and reinstalling the waste toner box or replacing with the new one.
