Page 210: Ribbon Cable Connectors
7018 Ribbon cable connectors Zero Insertion Force (ZIF) connectors Zero Insertion Force (ZIF) connectors are used on the boards and cards used in this printer. Before inserting or removing a cable from these connectors, read this entire section. Great care must be taken to avoid damaging the connector or cable when inserting or removing the cable.
Page 211: Horizontal Top Contact Connector
7018 Horizontal top contact connector This FRU contains a horizontal top contact cable connector. Read the instructions before proceeding. The horizontal top contact connector uses a back ﬂip locking actuator to lock the ribbon cable into the Zero Insertion Force (ZIF) connector. The cable is inserted horizontally into the connector. Warning—Potential Damage: When opening or closing this type of actuator, gently lift or close the two tabs located on each end of the actuator.
Page 212 7018 Inserting a cable into the horizontal top contact connector When installing the cable, check the locking actuator to ensure it is in the unlocked position. The tabs on the ends of the actuator are vertical when the actuator is unlocked. Insert the cable with the contacts on the cable facing up.
Page 213 7018 Rotate the locking actuator to the locked position. The cable should not move while this step is performed. If the cable moves, open the actuator, reposition the cable, and then close the actuator to the down position. Parts removal...
Page 214: Horizontal Bottom Contact Connector

Warning—Potential Damage: When opening or closing this type of actuator, gently push or pull the two tabs located on each end of the actuator.
Page 221 7018 Inserting a cable into the horizontal sliding contact connector When installing the cable, check the locking actuator to verify it is in the open position. If you are opening the connector, pull back on both end tabs using equal force to avoid breaking the connector. Insert the cable with the contacts on the cable facing away from the locking actuator.
Page 222 7018 Slide the locking actuator towards the connector, locking the cable into place. The cable should not move when this step is performed. If the cable moves, open the actuator, reposition the cable, and then close the actuator to the down position. Parts removal...
Page 223: Low Insertion Force (Lif) Connector
7018 Low Insertion Force (LIF) connector This FRU contains a Low Insertion Force (LIF) connector. Read the instructions before proceeding. Warning—Potential Damage: When installing a cable into an LIF connector, care must be taken to avoid bending the edges of the cables and damaging the contacts on the cables. Inserting a cable into the LIF connector Looking at the connector, take note on which side the contacts are located.
Page 224: Printhead Assembly Adjustment
7018 Printhead assembly adjustment A printhead must be correctly positioned after it has been removed. Use a sharp pencil or a small, ﬂat-blade screwdriver to mark the location of the old printhead on the printer frame. Align the new printhead relative to the location of the old printhead.
Page 225 7018 Make a second vertical fold near the center so that the left side top edge aligns with the right side top edge. If the grid lines of the right ﬂap align below the corresponding lines on the left side, then adjust the printhead clockwise relative to the printer, and recheck.

The power consumption levels listed in the previous table represent time-averaged measurements. Instantaneous power draws may be substantially higher than the average. Values are subject to change. See www.lexmark.com for current values. Sleep Mode This product is designed with an energy-saving mode called Sleep Mode. The Sleep Mode saves energy by lowering power consumption during extended periods of inactivity.

Page 437: Theory Of Operation
7018 Theory of operation POR sequence As the printer is turned on, the engine code goes through a series of tests to verify hardware integrity. If a hardware failure is detected, then it is reported to the printer. If the POR sequence cannot be completed successfully, then the printer may post an error message.

Page 440 7018 Charge Charge roller Photoconductor drum A uniform negative electrical charge is applied by the charge roller to the surface of the photoconductor drum. The photoconductive properties of the surface material allow it to hold the charge as long as it is not exposed to light.
Page 441 7018 Expose Photoconductor drum Printhead The printhead emits the light that contacts the surface of the photoconductor drum. The light turns on or off coinciding with the digital latent image. The light causes areas of the photoconductor drum surface to lose charge, resulting in a relative opposite polarity.
Page 442 7018 Develop Developer roller Toner cartridge Photoconductor drum The developer unit applies the toner from the toner cartridge to the photoconductor drum. The difference in charge causes the toner particles to attract to the photoconductor drum areas which are exposed to light. Theory of operation...
Page 443 7018 Transfer Charge roller Transfer roller Paper The transfer roller applies a positive charge to the paper, which is pressed between the transfer roller and the photoconductor drum. Due to relative opposite polarities between the paper, from the transfer roller, and the photoconductor drum, from the charge roller, the charge attracts the toner onto the paper.
Page 444 7018 Fuse Fuser Paper Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. For the ﬁnal part of printing, the paper is transported to the fuser where heat and pressure are applied to it.

7018 Printer paper path One‑sided print job Photoconductor drum First input roller MPF pick roller Second input roller Pick roller Separator roller Transfer roller Fuser Fuser exit roller Paper exit roller The pick roller picks and feeds the paper to the separator roller. The separator roller feeds the paper to the second input roller, which feeds it to the ﬁrst input roller.
Page 447 7018 The deskew shutter along the ﬁrst input roller corrects the skew on the paper. The ﬁrst input roller feeds the paper to the transfer roller. At the transfer roller, the photoconductor drum transfers the developed image to the paper to create the printed image. As the paper passes the fuser, heat and pressure are applied to permanently bond the toner to the paper.

Page 450: Tray Drive
7018 Tray drive Pick roller Separator roller To prepare for feeding, the lift plate raises to push the paper against the pick roller. The lift plate stops pushing at the point where the pick roller is at the proper height for picking. After the pick roller is in position, it feeds the topmost paper to the separator roller.
Page 451: Adf And Scanner Operation
7018 ADF and scanner operation Flatbed scanner drive Scanner glass Motor (FB scanner) Sensor (FB CIS home) The ﬂatbed scanner has a scanner lamp that is used to illuminate the surface of the document. The reﬂections produced are processed to create the scan image. For ﬂatbed scan jobs, the ﬂatbed scanner moves across the scanner glass area to scan the front side of the document (facedown).

Page 453: Adf Paper Path Sensors
7018 After the sensor (ADF paper present) detects paper in the ADF tray, the pick roller drops and advances the paper into the ADF. The paper passes through the feed roller and separator roller. The separator roller minimizes the possibility of feeding multiple sheets.
