ProblemCauseSolution Received faxes are too light or are printing only on half of the page.The device ran out of toner while printing a fax.The device stores the most recently printed faxes. (The amount of memory that is available determines the actual number of faxes stored for reprinting.) As soon as possible, replace the print cartridge, and then reprint the fax. See Reprinting a fax. The fax that was sent was too light.Contact the sender and have the sender resend the fax after altering the settings. Problems sending faxes Use the information in this table to solve problems that might occur when sending faxes. ProblemCauseSolution The document stops feeding in the middle of faxing.The maximum length of a page that you can load is 381 mm (15 inches).

Performance problems ProblemCauseSolution Faxes are transmitting or being received very slowly.The fax might be very complex, such as one with many graphics.Complex faxes take longer to be sent or received. Breaking longer faxes into multiple jobs and decreasing the resolution can increase the transmission speed. The receiving fax machine might have a slow modem speed.The device only sends the fax at the fastest modem speed that the receiving fax machine can accept. The resolution at which the fax was sent or is being received might be very high.If you are receiving the fax, call and ask the sender to lower the resolution and resend the fax. If you are sending the fax, lower the resolution and resend the fax. See Changing the default light/dark (contrast) setting to change the default setting. Your telephone line might not be working.Hang up and resend the fax. Have the telephone company check the telephone line. You are sending a fax via an international call.You must allow more time to transmit fax jobs internationally. The fax activity logs or fax call reports are printing at inappropriate times.The fax activity log or fax call reports settings are not correct.Print a Configuration page and check when the reports print.
