Error Code Error Message Solutions ERROR 20 ERROR 200 Input Paper Sensor was not triggered - Paper may be jammed at the sensor. Remove toner cartridge for better access to jammed paper.   Paper not being picked up check paper tray & pickup rollers Replace rollers if worn smooth or cracked ERROR 21 The exit sensor was not made in time after the input sensor as made.   ERROR 22 The exit sensor was not unmade in time.   ERROR 23 Jam at the duplex unit. Paper is either not leaving the duplex entry sensor in time or not making or unmaking the duplex exit sensor in time. See “Duplex” on page 2-16   Error 24 The defined paper size is too short to print data as formatted.   Error 25 Input sensor made at wrong time. May be due to the paper feeding manually while motors running and previous page in path.   Error 26 Duplex unit is installed but paper tray is not sensed.   Error 27 Envelopes/paper loaded are wrong size.  Load correct size Error 28 Input sensor not made after pick attempt. Tray is empty or not installed, paper jam in entry throat, or printer is requesting a manual feed.   Error 29 The output bin sensor has not been unmade.See “Output Bin Sensor” on page 2-22.   Error 30 30 Top Cover Open or Print Cartridge Missing Make sure the spring-mounted pin on the printhead shroud is installed properly and that it is detected by the ramp on the print cartridge as the cover closes. The pin should enter the tower on the HVPS and depress the cover switch.   Error 31 Error code 31 is displayed when the top front cover is closed and a defective print cartridge is detected. It may take the printer 10-20 seconds to determine if the print cartridge is defective. Note: This error indicates the printer was able to read the cartridge ID, but the ID did not pass the verification test. Remove and reinstall print cartridge.

Remove the duplex front cover to access the jam area. If the paper is jammed in the rear of the duplex, replace the duplex front cover and open the duplex rear door. If the paper is not jammed in the duplex unit, then it may be jammed in the rear of the printer. Open the printer rear door to access the jam. Remove jammed media Error 24X Paper Jam - Check Tray "X" Primary: Paper is jammed around Tray X (X=tray 1 thru 5). Try opening Tray X. If the tray is difficult to remove, then you may have to remove the tray above or below tray X to remove the jammed pages. Secondary: When this message is displayed, do not remove accumulated sheets during the jam clearance procedure as the printer will not reprint the removed sheets. Also, if the accumulated sheets are removed, the portion of the job printed after the jam will not be stapled. Remove jammed media Error 250 Paper Jam - Check MP Feeder Paper is jammed in the multipurpose feeder. Remove jammed media Error 90X Software Error Unrecoverable software error. If one of these errors appeared during POST, or while the printer was idle (not printing or receiving data), or while trying to print one of the internal test pages, replace the system board. If the error appeared while sending a job from the host to the printer, turn the printer off, then turn it on and try again.   Error 901 Engine Flash Indicates the Flash with the system code program is defective   Replace System Board Request Quote Error 914 DC Pick Motor - No Encoder Feedback Check the integrated paper tray, tray 1, for paper loading problems. Reload the paper and do a power on reset. Check connecting cables for continuity. If cables, connectors and connections are good replace assemblies listed. Replace the Autocompensator Assy. Replace System Board Request Quote Error 917 Check the transfer roll for toner buildup, surface damage to the roll, oil, or other contaminants on the surface of the roll. Replace the transfer roll as necessary. Transfer Roll Error Cannot start servo operation. Verify correct cable connections from the Engine board to the HVPS. Make sure there is continuity between the transfer roller and its contact on the HVPS; replace the transfer roll if the continuity is correct. If there is no continuity, make sure the HVPS contact returns to its upward limit when depressed, and make sure the left bearing of the transfer roll is making proper contact. Check the left and right transfer roll arm assembly to make sure it is fastened and locked in the down position if applicable to your machine.   Error 920 920 Fuser Error Fuser is below temperature while printing. A 920 error caused by low line voltage can sometimes be cleared by turning the machine off and then on again. Error 920.X and 922.XX may display for a cold fuser. Some 920.xx error codes may be cleared by turning the printer on and off and allowing it to complete POR. In general, fuser errors require replacement of the fuser Fuser errors can be from a cold fuser or an overheated fuser. Newer machines display a sub code to indicate which condition applies. Additional info on X and XX codes available by email. Error 921 Fuser is below standby temperature when idle. Indicates that the fuser is below standby temperature when the printer is idle.   Error 922 Fuser failed to reach standby temperature. Check the continuity of the fuser lamp at the two heavy leads. If an open circuit, replace the lamp or fuser. The fuser assembly is subject to mechanical wear and heat related degradation and is a scheduled replacement item in most machines at between 200K and 350K pages. The fuser is the main part of a printer maintenance kit. The fuser can usually be reomoved with two simple screws and the entire assembly lifted out. We can email further info if needed for your particular model.  It can also be the LVPS (low voltage power supply) or a fuse in the power supply on some models.  Use caution when measuring AC voltages.  Check LVPS cable for continuity. Thermistor Check:                                     HOT - J2-1 - J2-2 = 2.5K ohms COLD = 150K ohms to 260K ohms            Replace fuser assembly Shop For:   Lexmark       Maintenance Kits Lexmark Fusers Error 923 Fuser is too hot while printing or when idle. Lexmark Fusers Error 924 924 Fuser Error - Open circuit detected in thermistor circuit. The thermistor provides feedback on the temperature of the fuser roller and when it fails, the fuser normally does not heat up. Lexmark Fusers Error 925 A 925 service error indicates the wrong fuser lamp is installed in the printer and does not match the one stored in the printer code. Check the fuser lamp for the correct type of lamp that should be installed. • Verify the line voltage is not exceeding the maximum rating for the printer.

Check printhead, cable, motor, system board. Power printer off one to two minutes. Open doors and covers and remove the toner cartridge. Make sure there is no paper jammed in the printer. Pay close attention to the area where the toner cartridge sits. The main motor is located just to the left of the toner cartridge. If either the 936 error or the 937 error returns after you power on the printer or when you try to print, the printer will require service. The main motor assembly may need to be replaced.
