10 PCDU D135/D136/D137/D138

11 PCDU Replacement Procedures Lubricant Bar Replacement The lubricant bar has a PM replacement interval of 300k. At this time, the lubricant bar and roller should both be replaced. If the machine continues to be used without proper drum lubrication, the drum will wear prematurely. The following back-up measures are implemented in case a technician forgets to, or cannot replace the lubricant at the required time. 1.At 300k, the machine can still be used, but a drum rotation counter begins. 2.When either of the lubricant end sensors is triggered, a "Near End" alert message is displayed. The machine can still be used. 3.At 12 km of drum rotation after the 300k point, an "End" alert message is displayed. At this time, the machine stops and cannot be used until the lubricant bar is replaced. This corresponds to about 20k sheets (5P/J) for the Office version, or about 27k sheets (25P/J) for the Pro version.

12 PCDU Replacement Procedures The PCDUs are located behind the toner supply unit. To access the PCDUs, you must remove the toner supply unit assembly.

13 PCDU Replacement Procedures Accessing the PCDUs First, remove the toner supply unit assembly, as mentioned previously. 2.Then, turn the transfer belt release lever counterclockwise and remove the six screws that hold the faceplate. 3.Next, remove the two handles that are taped to the upper left corner.

14 PCDU Replacement Procedures Accessing the PCDUs Use the handles to pry loose the edges of the faceplate little by little at the four locations shown. 5.Pull out little by little uniformly. 6.Then grab the two handles built into the faceplate at the left and right, and pull the faceplate out. Do not close the drawer unit with the faceplate removed, because there is a risk of damage to the paper transfer roller unit.

15 PCDU Replacement Procedures Removing a PCDU - 1 Unlock the lever [A] and pull out the PCDU [B] from the machine.

16 PCDU Replacement Procedures Removing a PCDU - 2 Put the PCDU [A] on its cradle [B] when performing service. The cradles are included in the machines accessories.

[A]: The locking lever properly fits into the hole in the machine frame. [B]: The locking lever is not properly fit in the hole in the machine frame.

18 PCDU Replacement Procedures Installing a PCDU - 2 After installing the faceplate, check the position of the locking levers again by looking through the holes. The lever should be straight [A], and not at an angle [B]. NOTE: Sturdy force is required to attach the faceplate, and this could knock the levers out of their horizontal alignment.

19 PCDU Replacement Procedures Installing a PCDU - 3 D137/D138: (Pro version) After you removing a PCDU and replacing it, or after installing a new one, be sure to execute SP to SP (DEMS: Execute).

20 PCDU Replacement Procedures Charge Roller After removing the charge roller unit, place it on a clean, flat surface with the roller facing up. D137/D138 (Pro Version): After removing the charge roller and replacing it, or after installing a new one, be sure to execute SP to SP (DEMS: Execute).

21 PCDU Replacement Procedures Removing a Drum To remove the drum from the PCDU [A], move it toward the front side (to the left as shown above), then pull it out from the rear side (the right side as shown above).

22 PCDU Replacement Procedures Installing a Drum - 1 When replacing a drum, apply lubricant powder (D ; zinc stearate) evenly with a brush.

23 PCDU Replacement Procedures Installing a Drum - 2 Lay the black protective sheet [B] that covered a new OPC drum on the development unit [A]. Attach the new OPC drum [A] then remove the protective sheet [B] from the bottom. D137/D138 (Pro Version):After replacing the OPC drum, or installing a new one, perform SP to SP (DEMS: Execute).

24 PCDU Replacement Procedures Drum Cleaning Unit - 1 After removing the cleaning unit, lubricant and toner streaks [B] can remain on the surface of the OPC drum [A]. This will cause stains on the charge roller. To prevent this, rotate the OPC drum in the direction of the arrow [C] before installing a new drum cleaning unit.

25 PCDU Replacement Procedures Drum Cleaning Unit - 2 After replacing the cleaning unit, attach the special tools [A] to the OPC drum (these are shipped with a new cleaning unit). With the flange [C], rotate the drum 1-2 times in the direction of the arrow [D]. D137/D138 (Pro Version): After replacing the drum cleaning unit, or after installing a new one, perform SP to SP (DEMS: Execute).

26 PCDU Replacement Procedures Drum Cleaning Unit Components - 1 When installing a new lubricant bar, a new lubrication roller must also be installed at the same time. Replace the cleaning blade, lubrication blade and side seals as a set. After attaching the side seals (x 2 each) on the cleaning unit and the lubrication unit, apply lubricant powder (D ; zinc stearate) to the side seals [A] with a brush (Upper diagram) Apply lubricant powder (D ) (zinc stearate) and yellow toner (D ) to the lubrication roller [A] (Lower diagram).

27 PCDU Replacement Procedures Drum Cleaning Unit Components - 2 Do not replace the drum cleaning unit or the drum cleaning blade at the same time as the following parts. ITB ITB Cleaning Unit ITB Cleaning Blade ITB Lubricant Bar ITB Lubricant Blade After replacing the drum cleaning unit or the drum cleaning blade, cleaning initial setting is performed automatically. But, after replacing the above five parts, you need to run SP (Force Apply Lubricant Execute) manually before cleaning initial setting runs. This is because, if cleaning initial setting runs automatically before running SP manually, the ITB cleaning blade will be turned up. If you need to replace the above five parts at the same time as replacing the drum cleaning unit or the drum cleaning blade, use the following procedure. 1.Clear the counter of the drum cleaning unit or the drum cleaning blade. 2.Replace the drum cleaning unit or the drum cleaning blade. (The cleaning initial setting automatically runs) 3.Clear the counters of the above five parts 4.Replace the above five parts 5.Run SP (Force Apply Lubricant Execute) manually

28 PCDU Replacement Procedures Lubricant Bar Replacement The lubricant bar has a PM replacement interval of 300k. At this time, the lubricant bar and roller should both be replaced as a set. If the machine continues to be used without drum lubrication, the drum will begin to wear out. So, the following back-up measures are implemented in case a technician cannot replace the lubricant at the required time. At 300k, the machine can still be used, but a drum rotation counter begins. When either of the lubricant end sensors is triggered, a "Near End" alert message is displayed. The machine can still be used. At 12 km of drum rotation after the 300k point, an "End" alert message is displayed. At this time, the machine stops and cannot be used until the bar is replaced. This corresponds to about 20k sheets (5P/J) for the Office version, or about 27k sheets (25P/J) for the Pro version.

29 Removing The Drum Motor - 1 Remove the 4 screws indicated in the red circles in the upper illustration. Do not touch the four screws indicated in the lower illustration. These screws are adjusted at the factory with a special tool. If you adjust these screws, the drum drive shaft will misaligned. Do not touch these screws.

30 Removing The Drum Motor - 2 When removing or assembling the drum shaft and motor: The joint between the drum shaft [A] and the motor [B] must be kept horizontal so that excessive load is not put on the drum shaft. In order to avoid stripping the fixing screw [C], use a box-type driver [D].

31 Replacing The Drum Motor In the Pro version, there is a HP sensor and actuator mechanism on the drum motor. If you forget to install the actuator, the machine will not work SC (K), SC (C), SC (M), SC (Y) occurs. This sensor is used for the DEMS system.

32 Removing The Development Motor Do not touch these screws. Remove the 4 screws indicated in the red circles in the upper illustration. Do not touch the screws indicated in the lower illustration. These screws are adjusted at the factory with a special tool. If you adjust these screws, the development unit drive will be inaccurate.
