Power Plug and Power Cord. 2. 3. 4. 5. 6. 7. 8. Always make sure that the power plug is fully completely into the wall outlet. A partially inserted plug could lead to heat generation (due to a power surge caused by high resistance) that can result in fire and other problems. Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A dirty plug can generate heat that can result in fire. Inspect the length of the power cord for cuts or other damage. A frayed or otherwise damaged power cord can cause a short circuit which could lead to a fire or injury from electrical shock. If the power cord is damaged in any way, call for service. Check the length of the power cord between the machine and power supply. Make sure the power cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can cause excessive heat to build up and this could result in fire. Make sure that the area around the wall outlet is free of obstacles so the power cord can be removed quickly in case of an emergency. Make sure that the power cord is grounded (earthed) at the wall outlet using the ground wire on the plug. Insert the power cord into the wall outlet directly. Never use an extension cord. When disconnecting the power plug from the wall outlet, always pull on the plug, not the cable. 3

RWARNING Protect the machine from dampness or wet weather, such as rain and snow. Unplug the power cord from the wall outlet before moving the machine. While moving the machine, take care that the power cord is not damaged under the machine. When disconnecting the power plug from the wall outlet, always pull the plug (not the cable). Do not allow paper clips, staples, or other small metallic objects to fall inside the machine. Keep toner (used or unused) and toner containers out of reach of children. For environmental reasons, do not dispose of the machine or expended supply waste at household waste collection points. Disposal can take place at an authorized dealer. The inside of this machine gets very hot. Do not touch the parts with a label indicating the hot surface. Otherwise, an injury might occur. The fusing section of this machine gets very hot. Caution should be taken when removing misfed paper. Keep the machine away from humidity and dust. Otherwise a fire or an electric shock might occur. Do not place the machine on an unstable or tilted surface. If it topples over, an injury might occur. Do not use aluminum foil, carbon paper, or similar conductive paper to avoid a fire or machine failure. If you use the machine in a confined space, make sure there is a continuous air turnover. If toner or used toner is inhaled, gargle with plenty of water and move into a fresh air environment. Consult a doctor if necessary. If toner or used toner gets into eyes, wash eyes immediately using lots of water. Consult a doctor if necessary. If toner or used toner is swallowed, dilute it by drinking lots of water. Consult a doctor if necessary. Avoid getting toner on your clothes or skin when removing a paper jam or replacing toner. If your skin comes into contact with toner, wash the affected area thoroughly with soap and water. If toner gets on your clothing, wash it using cold water. Hot water will set the toner into the fabric and might make removing the stain impossible. SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame. 2. Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.) 3.

4. TROUBLESHOOTING PAPER DELIVERY PROBLEMS Important: For details about the items displayed in [Adjustment] menu, see the Adjustment Item Menu Guide. Problem Cause Solution The ends of the sheets are slightly curled. Sheets cannot be delivered. Sheets are delivered skewed. The side-to-side registration is wrong. The tray's paper setting does not match the size of the paper loaded in the tray. Sheets of an undetectable type, such as color or preprinted sheets, are being used. The paper size cannot be detected because sheets no wider than 47 mm (approx. 5.787") are being used. The ends of the sheets are slightly curled. The tray s paper guides are not adjusted correctly. Paper or a paper fragment is jammed inside the machine. Sheets of an undetectable type, such as color or preprinted sheets, are being used. The paper size cannot be detected because sheets no wider than 47 mm (approx. 5.787") are being used. Remove the sheets from the paper tray, flatten and fan them thoroughly, and then put them back into the paper tray. Change the tray's paper setting so it matches the size of the loaded paper. In [Adjustment] menu, select [Detect Side Regist] and [Detect Skew] to disable side-to-side registration and skew detection, and then adjust the image position in [Side-to-Side Registration]. Do this for each affected tray. To print on narrow sheets (39.7-47 mm [approx. 5.5-5.787 in.]), in [Adjustment] menu, select [Detect Side Regist] and [Detect Skew] to disable side-to-side registration and skew detection, and then adjust the image position in [Side-to-Side Registration]. Do this for each affected tray. Remove the sheets from the paper tray, flatten and fan them thoroughly, and then put them back into the paper tray. Adjust the tray's side paper guides and end paper guide according to the paper size. Remove the jammed paper. In [Adjustment] menu, select [Detect Side Regist] and [Detect Skew] to disable side-to-side registration and skew detection, and then adjust the image position in [Side-to-Side Registration]. Do this for each affected tray. When printing on narrow sheets (39.7-47 mm [approx. 5.5-5.787 in.]), in [Adjustment] menu, select [Detect Side Regist] and [Detect Skew] to disable side-to-side registration and skew detection, and then adjust the image position in [Side-to-Side Registration]. Do this for each affected tray. 29

Problem Cause Solution The ends of the sheets are slightly curled. Multiple sheets feed in at once. Double feeding occurs when using the LCT. Sheets are delivered with bent corners. Sheets are delivered curled. Sheets of differing paper types or thickness are loaded in the same paper tray. Sheets of an undetectable type, such as color or preprinted sheets, are being used. Paper fed from the LCT sticks together. Sheets are not loaded correctly in the tray. Excessively curled sheets are being used. Excessively curled sheets are being used. Remove the sheets from the paper tray, flatten and fan them thoroughly, and then put them back into the paper tray. Removed mixed sheets from the paper tray, and then reload the paper tray with sheets of one type and thickness only. In [Adjustment] menu, select [Detect Multi Feed] to disable multi-feed detection. Change the [Blow Fan Duty Adj.] settings. Specify the same value for both the front and rear fans. Increase the value in increments of 0 starting from 70.
