About fax machines
Custom features
Do you have Voice Mail on the phone 
line?
If you have Voice Mail on the phone line 
where you will install your new machine, 
there is a strong possibility that Voice Mail 
and the machine may conflict with each other 
while receiving incoming calls.
Why should there be problems?
Since both the machine and Voice Mail will 
pick up the call, after the number of rings you 
have set, each of them has the ability to keep 
the other from receiving calls.

Fax tones and handshake
When someone is sending a fax, the fax 
machine sends fax calling tones (CNG 
tones). These are quiet, intermittent beeps 
every 4-seconds. You’ll hear them after you 
dial and press Black Start or Color Start and 
they will continue for about 60 seconds after 
dialing. During that time, the sending 
machine must begin the “handshake” or 
connection with the receiving machine.
Each time you use automatic procedures to 
send a fax, you are sending CNG...

Handling and using special 
paper
The machine is designed to work well with 
most types of xerographic and bond paper. 
However, some paper variables may have an 
effect on print quality or handling reliability. 
Always test samples of paper before 
purchasing to ensure desirable performance. 
Some important guidelines when selecting 
paper are:
■Supplier should be informed that the 
paper or envelopes will be used in a color 
laser machine.
■Preprinted paper must use inks that can...

Envelopes
Most envelopes will be suitable for your 
machine. However, some envelopes will 
have feed and print-quality problems 
because of the way they have been made. A 
suitable envelope should have edges with 
straight, well-creased folds and the leading 
edge should not be thicker than two pieces of 
paper. The envelope should lie flat and not be 
of baggy or flimsy construction. You should 
buy quality envelopes from a supplier who 
understands that you will be...

Labels and transparencies
The machine will print on most types of labels 
and transparencies designed for use with a 
laser machine. Labels should have an 
adhesive that is acrylic-based since such 
material is more stable at the high 
temperatures in the fusing unit. Adhesives 
should not come in contact with any part of 
the machine, because the label stock may 
stick to the OPC belt or rollers and cause 
jams and print quality problems. No adhesive 
should be...
