40K PM Summary: 
 
Process Unit: 
 
Drum Replacement-  
•  Use drum units or drum kits. If using drum kits, inspect the cleaning system for wear or damage 
when replacing the drum blade and reception seal. Clean the discharge lamps.  
(AR-C25DU, AR-C25DK) 
 
Note : The black drum for the AR-C160 has been changed - the replacement interval is 80K and the 
rear flange of the drum is “keyed” differently than the colour drums. They are NOT interchangeable.  
(AR-C16DR). However, the cleaner blade, reception seal and main charger unit for Black will require 
replacing at 40k (AR-C16MK) 
 
Warning: 
Do not loosen the red screws on the DSD holders under any circumstances! The DSD holders are 
adjusted in the factory and cannot be adjusted in the field. If the alignment is altered, the gaps between 
the drum and developer unit will not be correct.
 
 
Developer- 
•  Remove the four developer units. Inspect the DV seals, gears, and bushings for wear or damage, 
and replace if necessary. Remove the old DV material and install the new Developer. Re-install the 
developer units. (AR-C15LD9 [CMY], AR-C15LD1 [K] ) 
 
Note: The black developer for the ARC160 is different. The replacement interval is now 80K and should 
not be used in the ARC150 and ARC250 copiers. (AR-C16LD1) 
 
ENSURE ALL DEVELOPER HAS BEEN ACCLIMATISED BEFORE INSTALLATION AND CYCLING. 
 
•  Before re-installing the process unit, remember to clean the slit glass on the four LSU units. Use 
cleaning cloth (UKOG-0289FCZZ) to avoid scratching the optics. 
 
Transport Unit: 
 
•  Remove and replace the transport belt waste container. (AR-C15HB) 
 
•  For AR-C160, replace the Resist Roller Cleaner (AR-C16MK) 
 
•  Remove and clean the Image density sensor and the grey reference plate on the underside of the 
sensor shutter. Ensure the shutter and solenoid function properly before re-installing (F2 errors 
could result). Once cleaned, re-calibrate the sensor using the grey patch (UKOG-0281FCZZ). 
 
Fuser Unit: 
 
•  Remove and replace the Upper Heat Roller and cleaning roller (AR-C15UH, AR-C25UH,  
AR-C16UH). 
 
•  Remove and replace the Lower Heat Roller and separation pawls (AR-C15LH, AR-C25LH,  
AR-C16LH). 
 
•  Remove and replace the oil-applying unit. Add a small amount of oil to “prime” the applying roller 
before installation (Oil included in the oil applying roller kit.). Also, replace the main oil filter on the 
transport section. (AR-C15KH, AR-C25KH)

Fuser Unit (Cont’d): 
 
•  Drain and replace the fuser oil. Ensure the oil container has been cleaned out or replaced to avoid 
contaminating the new oil. (AR-C15SL) 
 
Note: Always clean the intake filter on the fuser oil pump on every call. Failure to do so may result in 
damage to the fuser components, and cause the fuser drive system to slow down or stall. 
 
  
Warning: 
Ensure the correct Upper Fuser Roller and Oil Applying Rollers are fitted to the corresponding machine. 
For example, the AR-C150 fuser roller diameter is 10mm smaller than AR-C250. Severe oil “splashing” or 
fuser lamp breakage may result if the incorrect items are installed.
 
 
Miscellaneous: 
 
Optical Section 
•  Ensure all mirrors including the CCD lens are clean and free from dust. Streaks on copies may be 
caused if the mirrors are “hazy” or dirty. 
•  Clean the CCD white reference plate. 
 
General- 
•  Remove and replace the “User” Waste Toner Container (AR-C15HB) 
• 
Remove and inspect all ozone & toner filters – clean if necessary 
 
 
 
80K PM Summary: 
 
 
In addition to the 40K PM procedures listed above, perform the following:- 
 
Process Unit: 
 
•  Replace all Ozone and Toner filters. (AR-C15FL) 
•  Replace 3 Developer seals -CMY. (AR-C15DS) 
 
 
 
Transport Unit: 
 
•  Replace all Transfer rollers. Clean the transfer holder unit thoroughly (AR-C15TX) 
      
(Not AR-C160) 
•  Replace the transfer belt cleaner blade. (AR-C150/250 – AR-C15TX) 
 
        
     (AR-C160 – AR-C16TK) 
 
160K PM Summary: 
 
In addition to the 40K and 80K PM procedures listed above, perform the following:- 
 
 
 
Transport Unit: 
 
•  Replace the transfer belt and separation pawls  (AR-C150/250 only) 
•  Replace the transfer belt and transfer rollers  (AR-C160 only)
