Consumable Parts & Maintenance Kits: CS820 & CX820, CX825, CX860 The CS820, CX820, CX825, and CX860 use a belt fuser. The belt fuser does not need a fuser wiper. All fusers will be Customer Replaceable Units (CRUs). No tools are needed to replace the fuser. The CS820/CX820/CX825/CX860 will post a message when the fuser rated life is reached. The customer may clear the end of life message and continue printing but to ensure best print quality, a Fuser Maintenance Kit should be installed at this time. Note: It is important to install the correct Fuser Maintenance Kit for the type of fuser that is installed in the printer. This fuser type (a two digit code) can be determined by: 1. Printing the menus page and referencing the fuser type in the Device Information section. 2. Physically checking the type two digit code on the fuser a. Viewable from the front of the fuser by removing the cartridge and IU. b. Viewable from the rear of the fuser by opening the rear door 3.

For colorless printing, the C, M, and Y first transfer rollers inside the transfer belt retract to move away from the C, M, and Y photoconductor rollers. As a result, image transfer only occurs on the K imaging unit. The motor (black only retract) controls the positions of the first transfer rollers.

Print Quality Diagnostic Tips Paper Orientation Before diagnosing print quality problems, take a moment to understand the concepts below. This will prevent confusion when diagnosing or escalating a problem. Know your paper orientation when diagnosing a print quality issue. References to direction such as horizontal and vertical must be made holding the paper in portrait orientation (long edges to the left and right) with the printed side facing you. Don t hold the paper in landscape orientation. This is a PORTRAIT Orientation This is a LANDSCAPE Orientation Know the direction of the print when diagnosing a print quality issue. References to the Process or the Scan direction refer to the direction in which the paper travels through the printer. LEF (Long Edge Fed) - Refers to paper that is fed into the printer on the long edge side. SEF (Short Edge Fed) - Refers to paper that is fed into the printer on the short edge side. Scan or Scanning is the direction in which the LED or laser writes to the Process is the paper s direction through the printer that corresponds to the rotation of the photoconductors.

General Print Quality Hot Tips and Tricks If paper jams and feed problems are encountered, follow the tips and simple rules of thumb which may solve the issue easily and quickly. Possible Cause Unsupported Media Type Action To Take Check the printer specifications if you are not sure. Unsupported Media Size Check the printer specifications. Unsupported Media Weight Check the printer specifications. Dry Media Change Input Source Paper that is left out of the package for a long period of time can dry out. Try using a fresh ream of paper. Try printing from a different input source. This will help narrow down the cause of some problems. Too Much Media Loaded Make sure the stack height does not exceed the indicated maximum height. Damaged Media Different Types of Media Loaded Too High / Too Low Relative Humidity Media Loaded Improperly Worn-Out Rollers Obstruction in the paper path Check if the media in the tray is wrinkled, creased, damp or curled. The media will not feed properly if damaged. Try a fresh ream of paper. Different types and/or weights of media loaded in the tray may cause missfeeds. Try using the same media. This can affect the media and/or printer and its ability to feed properly. Check the printer specifications to see if it is located in an ambient environment. Reposition the media in the tray or option to make sure that is loaded properly. The media guides should be flushed against the media, but not too tight. Worn-out rollers may cause feed problems. Check the page count of the printer to see if it is time for a maintenance kit to be installed. If paper, staples, paper clips or other items are left in the printer, they can prevent the media from feeding properly. Check if there are any visible obstructions.

2nd Transfer Belt This part is extremely hard to replace due to its positioning. Controller Board / Secure Element SIM Card Contains printer NVRAM and possible and possible Secure Element SIM card. A Secure Element SIM card is standard installation on the Lexmark CX860 / XC8160. When replacing this part: Follow recommended Controller Board Backup procedures for the settings contained on the Controller Board (see Restore Tool in the Knowledgebase Service Manual). Check for a Secure Element SIM Card on the existing Controller board. If present, move to the new controller. If the card is lost, customer data will be lost and the machine may have to be replaced. **Until EC1 is released, you will NOT receive an error if the Secure Element SIM card is missing. This part contains NVRAM. Use proper NVRAM preservation procedures do not replace this card with another card that contains NVRAM (Control Panel) at the same time before PORing between parts. Be careful of the cable routing through the holes in the cage. You may want to take a snapshot before removing the cage to make it easier to install correctly. Routing the cables incorrectly may cause damage to the wires from the EP Drive motors. The Scanner HDMI cables that connect to the Controller board can be switched and cause a scanner error. Lexmark Product Study Guide 58 V1.2

Control Panel This part contains NVRAM. Use proper NVRAM preservation procedures do not replace this card with another card that contains NVRAM (Controller Board) at the same time before PORing between parts. EP, Developer, Toner Add Gearbox This part is large and cumbersome to remove and replace. Fuser / Transfer Module Gearbox The part has has special settings that must be set in Diagnostics menu once the installation is complete. These settings are calibration data that will affect print quality. If not set, the images on the page could look stretched or compressed. The part should ship with a sheet with the settings to be entered. Laser (Printhead) Although this part is easy to remove, you need a short, stubby hex driver with a ball end to remove one screw. Once replaced, a mechanical and electrical calibration needs to be performed to align the 4 colors. K (black) is aligned first with the mechanical adjustment (there is a screw behind Tray 1); next align CMY (cyan, magenta, yellow) using the Alignment Menu in Diagnostics. Left Door Assembly The Left door comprises three separate parts: MPF, Duplex, and Left Door. This part is extremely hard to reassemble due to a shaft that has to pass through all pieces including 2 brackets on the MPF. If you follow the service manual instructions closely, you can reassemble this piece fairly easily. LVPS The LVPS itself is not difficult; however, if the cage it s mounted to has to be removed during another part replacement you need to be careful of the hinged connection or you will stress and break the solder joints on the board. PC Drive Motors These individual motors are not replaceable separately they have to be replaced as an assembly with the EP Drive FRU. This is because the EP Drive assembly contains a chip that holds calibration settings for the drive motors and communicates this to the Controller Card. The timing of these motors has to be very precise and would be impossible to replace one and match the settings. Replacing only one could cause print quality issues or other unforeseen issues.
