remove the image drum (See “Image drum replacement” on
page 121.), tap the toner cartridge, and slowly swing it 20 to 30
degrees vertically several times. Be careful not to let the toner
leak from the cartridge. If this does not work, the image drum
unit may need to be replaced. Contact your supplier to get a
replacement.
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 “Initial set up” on page 64.).
MFP WILL NOT POLL A REMOTE MACHINE
Call the person at the remote machine and make sure that they
have loaded documents and that their machine is set to polling
transmission mode.
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 MFP
(See “Connecting to a PBX” on page 68.).
MFP ALWAYS ANSWERS BEFORE ITS POSSIBLE TO USE THE EXTERNAL
TELEPHONE
If an external telephone is connected, change the MFP’s ring
response setting (See “Advanced set up” on page 65.).
F AXES 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 problem could also be communication related.
