Faxes are transmitting or being received very slowly. Cause Solution The resolution at which the fax was sent or is being received is very high. A higher resolution typically results in better quality, but also requires a longer transmission time. If you are receiving the fax, call and ask the sender to decrease the resolution and resend the fax. If you are sending, decrease the resolution or change the Page Content mode setting. See the fax guide for information about changing the settings. A poor telephone-line connection is forcing the device fax and the sending or receiving fax machine to slow down the transmission to adjust for errors. Cancel and resend the fax. Have the telephone company check the telephone line. Faxes are not printing at the device. Cause Solution There is no media in the input trays. Load media. Any faxes received while the input trays are empty are stored and will print after the trays have been refilled. The Schedule Printing of Faxes mode is enabled. Faxes will Disable the Schedule Printing of Faxes mode. See the fax not print until it is disabled guide for information about changing the setting. The device toner level is low, or it has run out of toner. Replace the print cartridge. The device stops printing as soon as it is low on toner or runs out of toner.
