Page 43: Selecting Paper
General information Selecting paper Paper guidelines Use the appropriate paper to prevent jams and help ensure trouble‑free printing. • Always use new, undamaged paper. • Before loading paper, know the recommended printable side of the paper. This information is usually indicated on the paper package. • Do not use paper that has been cut or trimmed by hand. •...
Page 44: Paper Characteristics
General information Paper characteristics The following paper characteristics affect print quality and reliability. Consider these factors before printing on them. Weight Trays can feed paper of varying weights. Paper lighter than 60 g/m (16 lb) may not be stiff enough to feed properly, and may cause jams. For more information, see the “Supported paper weights” topic. Curl Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems.
Page 45 General information Fiber content Most high‑quality xerographic paper is made from 100 percent chemically treated pulped wood. This content provides the paper with a high degree of stability, resulting in fewer paper feeding problems and better print quality. Paper containing fibers such as cotton can negatively affect paper handling.
Page 46: Unacceptable Paper
General information Unacceptable paper The following paper types are not recommended for use with the printer: • Chemically treated papers that are used to make copies without carbon paper. They are also known as carbonless papers, carbonless copy paper (CCP), or no carbon required (NCR) paper.
Page 47: Storing Paper
General information Storing paper Use these paper storage guidelines to help avoid jams and uneven print quality: • Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. • Extend the time several days if the storage or transportation environment is very different from the printer environment.
Page 48: Selecting Preprinted Forms And Letterhead
General information Selecting preprinted forms and letterhead • Use grain long paper. • Use only forms and letterhead printed using an offset lithographic or engraved printing process. • Avoid paper with rough or heavily textured surfaces. • Use inks that are not affected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements; latex inks might not. •...

Page 63: Using Safe Mode
Diagnostics and troubleshooting Using Safe Mode Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue offering as much functionality as possible despite known issues. WARNING—POTENTIAL DAMAGE Safe Mode is intended as a short‑term workaround and should be used only in the case of a non‑critical error when a print job must be completed before service can be arranged to repair the printer. The printer must be returned to standard operating mode before diagnostics can be run or full‑function printing can continue.

Page 66: Non-Lexmark Supply
Use of third-party supplies or parts may affect the performance, reliability, or life of the printer and its imaging components. All life indicators are designed to function with Lexmark supplies and parts and may deliver unpredictable results if third-party supplies or parts are used. Imaging component usage beyond the intended life may damage the Lexmark printer or associated components.
Page 67: Securing The Printer
Diagnostics and troubleshooting Securing the printer Resetting the printer without admin credentials • Resetting the printer or replacing the controller board deletes all security settings. • Before changing the security settings, ask permission from your administrator.

Page 638: Theory Of Operation Por Sequence
Theory of operation 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 639: Printer Control
Theory of operation Printer control The printer uses a single processor for both RIP and engine functions. The raster image processor (RIP) code performs system responsibilities such as PC connection, LAN, ISP attachments, and bitmap generation. The engine code performs tasks related to the operation of the electrical and mechanical device systems such as motors, lasers, power supplies, and fusers.

Theory of operation EP process Charge Charge theory Charge roller Photoconductor drum The charge roller applies a uniform negative electrical charge to the surface of the photoconductor drum. The photoconductor drum, because of its photoconductive properties, holds the charge as long as it is not exposed to light. Service tips...
Page 643: Expose
Theory of operation • If the surface of the charge roller is damaged, such as having a nick or pit, then the charge on the photoconductor drum is uneven. A repeating mark may appear on the printed page. For more information, see See "Repeating defects "...
Page 644 Theory of operation The printhead laser emits the light that contacts the surface of the photoconductor drum. An invisible image, called digital latent image, is written as the light turns on or off. The light causes areas of the photoconductor drum surface to lose charge, resulting in a relative opposite polarity.
Page 645: Develop
Theory of operation Develop Develop theory Toner cartridge Developer roller Photoconductor drum The developer roller applies the toner from the toner cartridge to the photoconductor drum. The relative opposite polarity in charge causes the toner particles to attract to the photoconductor drum areas which were exposed to light.
Page 646: Service Tips
Theory of operation Service tips • Do not touch the surface of the developer roller with your bare hand. The oil from your skin may cause a charge disparity on the surface, and the toner may no longer stick properly. The result can be repeating blotches or voids on the printed page or patches of light print.
Page 647 Theory of operation Continued from page 646 Transfer roller Paper The transfer roller applies a positive charge to the paper, which is pressed between the transfer roller and the photoconductor drum. The charge on the paper received from the transfer roller is positive. The charge on the photoconductor drum received from the charge roller is negative.
Page 648: Clean
Theory of operation Clean Transfer belt clean Waste toner bottle Cleaning blade Photoconductor drum The cleaning blade removes the toner residue from the photoconductor drum. The cycle (charge, expose, develop, transfer, and clean) repeats until the whole image is transferred to the paper.
Page 649: Fuse
Theory of operation Fuse Fuse theory Fuser Paper Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. Paper is transported from the transfer roller to the fuser where heat and pressure are applied to it.
Page 650 Theory of operation • Toner rubbing off a printed page indicates a malfunctioning fuser or an incorrect paper type setting. Always check the paper type setting before replacing the fuser. A common mistake is to print on heavier paper, such as card stock, with the paper type set to plain paper. •...

Page 653: Two-Sided Print Job
Theory of operation Continued from page 652 Fuser roller 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. For MPF print jobs, the MPF pick roller picks and feeds the paper to the first input roller.
Page 654 Theory of operation Two‑sided print job Paper exit roller Duplex rear roller Duplex front roller Second input roller After the first side is printed, the paper reverses direction to get its opposite page printed. The paper travels along the duplex path until it reenters the second input roller. From there, the paper continues its path until the print job is done.

Theory of operation ADF and scanner operation Flatbed scanner drive Flatbed scanner drive Scanner glass area Motor (flatbed CIS scanner) Calibration reference strip ADF glass area Flatbed CIS scanner Sensor (flatbed CIS scanner) The flatbed scanner has a contact image sensor (CIS) scan module that illuminates the surface of the document.
Page 658 Theory of operation distance relative to the calibration reference strip. To maintain the correct shading levels if needed, the CIS scanner scans the white surface of the calibration reference strip. During ADF scan jobs, the CIS scanner stays at the ADF glass area to scan the front side of the document.
