Troubleshooting 54

2Check to see if error correction is set to On.

If it is not set to On, then press the arrow buttons to select On, and then press OK .

ENABLE AUTOMATIC FAX CONVERSION

If the receiving fax machine does not support color fax, then this option automatically converts the outgoing color fax to black and white. It also automatically reduces the resolution of the fax to a resolution that the receiving machine can support.

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Dialing and Sending > OK > Auto Fax Convert > OK

2Check to see if automatic fax conversion is set to On.

If it is not set to On, then press the arrow buttons to select On, and then press OK .

MAKE SURE THAT THE DIAL PREFIX SETTING IS CORRECT

The dialing prefix is the number or series of numbers that you press before you can dial the actual fax number or telephone number. If the printer is in an office setting or in a private branch exchange, this can be a specific number that you need to press so you can make a call outside the office.

Make sure that the dial prefix entered in the printer is correct for your network.

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Dialing and Sending > OK > Dial Prefix > OK

2Press the arrow buttons to create or modify the prefix.

3If the prefix is not correct, enter the correct prefix, and then press OK .

Cannot receive faxes

If the “Fax troubleshooting checklist” does not solve the problem, then try one or more of the following:

MAKE SURE THAT YOU HAVE CONFIGURED THE CORRECT SETTINGS FOR YOUR SETUP

The fax settings depend on whether the printer is connected to its own fax line or shares the line with other devices.

If the printer is sharing the telephone line with an answering machine, then make sure that the following are set:

•Auto Answer is On.

•The printer picks up on a greater number of rings than the answering machine.

•The printer picks up on the correct distinctive ring (if you subscribe to a distinctive ring service).

If the printer is sharing the telephone line with a telephone subscribed to voice mail, then make sure that the following are set:

•Auto Answer is Off (if you have only one number on the telephone line).

•The printer picks up on the correct distinctive ring (if you subscribe to a distinctive ring service).

MAKE SURE THAT THE PRINTER IS CONNECTED TO AN ANALOG PORT

The printer is an analog device. If you are using a PBX system, then make sure that the printer is connected to an analog port on the PBX. You may need a digital line converter that converts digital signals into analog signals.

MAKE SURE THAT THE PRINTER MEMORY IS NOT FULL

The printer saves an incoming fax to the printer memory before it prints the fax. If the printer runs out of ink or runs out of paper while receiving the fax, then the printer saves the fax so you can print it later. However, if the printer memory is full, then the printer may not be able to receive more incoming faxes. An error message appears on the display when the printer memory is full. Resolve the error to free up space in the printer memory.

MAKE SURE THAT FAX FORWARDING IS DISABLED

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Ringing and Answering > OK > Fax Forward > OK

2Press the arrow buttons to scroll to Off, and then press OK .

INCREASE THE RINGER VOLUME

If you set the printer to receive faxes manually (Auto Answer Off), then increase the ringer volume.

MAKE SURE THAT YOU HAVE THE CORRECT MANUAL ANSWER CODE

If you set the printer to receive faxes manually (Auto Answer Off), then you need to press the correct code when a fax comes in so that the printer can receive it.

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Ringing and Answering > OK > Manual Pickup Code > OK

2Copy the manual answer code that appears on the display.

Note: To increase the security, you can change your manual pickup code to a number that only you know. You can enter up to 7 characters for your code. The valid characters are the digits 0–9 and the characters # and *.
