Documents received are light or have vertical streaks on
them, and machine is not out of toner:
Lift the top cover and gently wipe the lens surface of the
machine's LED array. Then check to see if the toner or image
drum need replacing (see "Replacing consumables and Spare
Parts" on page 81).
Machine is set for delayed transmission but it did not send:
Check the display to make sure that the machine's clock is set to
the correct time (see Clock Adjustment).
Machine 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.
Machine 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).
Machine always answers before it's possible to use the
external telephone:
If an external telephone is connected, increase the machine'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 problem could also be communication related.
The display shows a invalid toner cartridge:
A toner cartridge that is not specified for use in this machine has
been installed. Contact the nearest supplier for service.
The display shows a invalid image drum:
An image drum that is not specified for use in this machine has
been installed. Contact the nearest supplier for service.
