Document appears blank at the other end. | The original was placed upside down. | When the original is placed directly on the exposure glass, the side to be scanned must face down. When the original is inserted into the ADF, the side to be scanned must face up.
Printed or sent images are spotty. | The exposure glass, scanning glass, or ADF is dirty. | Clean them. See "Cleaning the Machine", About This Machine. Make sure ink or correction fluid is dry before placing originals.
Reception is possible, but transmission is impossible. | There are regions and telephone exchanges where a dial tone can not be detected. | Turn the dial tone detection off in User Parameters. For details about how to do this, see "Parameter Settings", Facsimile Reference.
Transmission failed due to "maximum e-mail size" error. | If the e-mail size specified on the machine is too large, the Internet Fax document cannot be sent. | In [Facsimile Features], under [Send Settings], set [Max. E-mail Size] to [Off], or set the maximum e-mail size to a larger value. Then, resend the document.
LAN-Fax Driver does not work. | The entered login user name, login password, or driver encryption key is incorrect. | Check your login user name, login password, or driver encryption key, and then enter them correctly. Contact your administrator.
LAN-Fax Driver does not work. | A high security level is set by the extended security function. | Contact your administrator.

The machine failed to print received fax documents. | In [Facsimile Features], under [Reception Settings], [Store] has been selected for [Reception File Setting]. | Print the fax documents using a Web browser or the Print Stored RX File function. See "Printing Received and Stored Documents" and "Viewing, Printing, and Deleting Received Fax Documents Using Web Image Monitor", Facsimile Reference.
The machine failed to print received fax documents. | The paper has run out. | Load paper into the tray. See "Changing the Paper Size", About This Machine.
While pressing [Manual E-mail RX], `"Cannot receive E-mails currently."` appears and e-mail cannot be received. | The machine is receiving an on-demand e-mail message (e-mail inquiry from the administrator). | After the e-mail is received, press [Manual E-mail RX], and then try again.

Printing
Problem | Causes | Solutions
--- | --- | ---
Print is slanted. | The paper is fed at a slant. | Load the paper correctly. See "Loading Paper", About This Machine.
Misfeeds occur frequently. | The number of feeding into the paper tray exceeds the capacity of the machine. | When loading paper into the paper tray, load paper only as high as the upper limit markings on the side fences of the paper. When loading paper on the bypass tray, load only as much paper as can be held between the guides on the bypass tray.
Misfeeds occur frequently. | The paper tray's side fences are set too tightly. | Push the side fences lightly, and then reset it.
Misfeeds occur frequently. | The paper is damp. | Use recommended paper. For details about recommended paper, see "Recommended Paper Sizes and Types", About This Machine. Use paper that has been stored in the recommended temperature and humidity conditions. For details about the proper way to store paper, see "Paper Storage", About This Machine.
Misfeeds occur frequently. | The paper is too thick or too thin. | Use recommended paper. See "Recommended Paper Sizes and Types", About This Machine.
Misfeeds occur frequently. | The paper is wrinkled or has been folded/creased. | Use recommended paper only and be sure its storage environment meets the recommended temperature and humidity conditions. For details about recommended paper and the proper way to store it, see "Recommended Paper Sizes and Types" and "Paper Storage", About This Machine.
Misfeeds occur frequently. | Printed paper is being used. | Do not load sheets that have already been copied or printed onto by another machine.
Misfeeds occur frequently. | Sheets are sticking together. | Fan the sheets thoroughly before loading them. Alternatively, feed the sheets into the machine one at a time.
Misfeeds occur frequently. | The friction pad, paper feed roller, or registration roller may be dirty. | Clean the pertinent section as necessary. See "Cleaning the Friction Pad and Paper Feed Roller" and "Cleaning the Registration Roller", About This Machine.
Sheets are feeding in together, resulting in jams. | The pages are sticking together. | Fan the sheets thoroughly before loading them. Alternatively, feed the sheets into the machine one at a time.
Copy paper becomes creased. | Printed paper is being used. | Do not load sheets that have already been copied or printed onto by another machine.
Copy paper becomes creased. | The paper is damp. | Use paper that has been stored in the recommended temperature and humidity conditions. See "Paper Storage", About This Machine.
Copy paper becomes creased. | The paper is too thin. | Use recommended paper. See "Recommended Paper Sizes and Types", About This Machine.
Edges of sheets are creased. | The paper is damp. | Use paper that has been stored in the recommended temperature and humidity conditions. See "Paper Storage", About This Machine.
Edges of sheets are creased. | You are using non-recommended paper. | Use recommended paper. See "Recommended Paper Sizes and Types", About This Machine.
Images are only partially printed. | The paper is damp. | Use paper that has been stored in the recommended temperature and humidity conditions. See "Paper Storage", About This Machine.
Black lines appear on the print produced at the destination. | The exposure glass, scanning glass, or ADF is dirty. | Clean them. See "Cleaning the Machine", About This Machine.
Images are smudged. | Smudging can occur if a printed side rubs against things such as the corner of the machine. | When removing copies from the output tray, do so carefully to avoid scuffing the printed side. If you are making many copies, remove them in small batches.
Background of received images appears dirty. Images from the back of the page appear. | Image density is too high. | Ask the sender to adjust the scan density settings. For details about how to change the density, see "Density (Contrast)", Facsimile Reference.
Received image is too light. | When using moist, rough, or processed paper, areas of print may not be fully reproduced. | Use recommended paper. See "Recommended Paper Sizes and Types", About This Machine.
Received image is too light. | The image density has been set too low. | Ask the sender to increase the scanning density. For details about how to change the density, see "Density (Contrast)", Facsimile Reference.
Received image is too light. | The original of the transmitted fax was printed on paper that is too thin. | Ask the sender to reprint the original on thicker paper, and then fax it again.
The image on the back side of duplex copies has mottled blank patches or is smudged. | Missing patches and smudges are caused by moisture leaking from the paper. | Do not install the machine in areas that are susceptible to low temperature. Use paper that has been stored where temperature and humidity conditions meet the limitations we recommend. For details about the paper storage conditions we recommend, see "Paper Storage", About This Machine.
