165 • Troubleshooting Fax problem checklist (MB470 MFP & MB480 MFP) If a problem occurs, read through the list of problems and solutions before calling for service. The MFP will not dial a telephone number. Check the power cable and wall outlet. Make sure that the telephone line (not external telephone or handset) is connected to the LINE socket on the back of the machine. If an external telephone is installed, lift the handset and check for a dial tone. If there is no dial tone, there may be a problem with the telephone line. If there is a dial tone, the MFP may be using the wrong dialling method (pulse or tone) for the region. If alternating tones are heard instead of dialling pulses and the region uses pulse dialling, change the call parameters. The display shows a communications error. This indicates any of a number of problems: • The MFP may be incompatible with the remote machine, or the remote machine may not be able to perform the function requested of it such as polling or confidential faxing. • The remote machine may also be out of paper or experiencing a paper jam. • Bad telephone line conditions can also cause communication errors. Try sending the fax again and check to make sure that the correct telephone number is being dialled. • If a prefix number must be dialled to get an outside line, or if the call is to an international destination, a pause may need to be entered after the dial prefix or international dialling code to tell the machine to wait for a dial tone. If there are frequent problems communicating with a particular remote machine, try programming the telephone number into a speed dial key, and then change the parameters for that key. • Lastly, either the local or remote machine may require servicing. Try sending a fax to another location to check the local MFP. Faxing is possible but the image of the document printed by the remote machine is very poor. If the faxed document has small type, complex illustrations, photos, or is very light or very dark, try changing the fax qualit y and density settings. Copy the document on the machine to determine how it will transmit. The problem may be caused by telephone line interference. Try sending the document again later. Fax sent but received message was completely blank. Make sure that the document is loaded correctly before faxing; with text face UP in the ADF or face DOWN on the glass.

166 • Troubleshooting Image of received fax is very poor. Try making a copy of a document on the local machine to make sure it is working properly. If there is still a problem, contact the person sending the fax and ask them to change their fax quality and density setting s. Ask the person to make a copy of the document on their machine to ensure that it is working properly. Then ask them to send the fax again. Dialling was tried with a Speed Dial/ Group Dial number but nothing happened. Make sure that the Speed Dial/ Group Dial number being used is programmed correctly.When dialling a two or three di git number, be sure press # or * before entering the number. Documents received are light or have vertical streaks on them, and MFP is not out of toner. Lift the top cover and gently wipe the lens su rface of the MFP’s LED array. Then check to see if the toner or image drum need r eplacing (see “Replacing consumable items” on page 137). MFP is set for delayed transmission but it did not send. Check the display to make sure that the MFP is set to the correct time and date (see “Clock Adjustment” on page 57). MFP is connected to a PBX but it is not possible to dial out. Be certain that the dial prefix is entered before the telephone number for each number dialled or programmed into the machine. Additionally, the machine must be programmed for PBX operation before it will work with a PBX (see “Connecting to a PBX” on page 67 ). MFP always answers before it is possible to use the external telephone. If an external telephone is connected, change the MFP’s ring response setting. Faxes received sometimes look distorted. If the document received is wider or longer than the paper loaded in the paper tray, the machine automatically reduces the width or length of the document so that it will fit on the paper. This type of proble m could also be communication related. Downloaded From ManualsPrinter.com Manuals
