POSTSCRIPT
Compatibility
Your QMS-PS 800+ printer uses the newest, most accu-
rate version
of the POSTSCRIPT Language, Version 46.l.
Other printers may use an older version of POSTSCRIPT.
This POSTSCRIPT version contains changes which may
not be compatible with some software packages written
for earlier versions. Although unlikely,
it is possible that
a software package developed using
an earlier version of
POSTSCRIPT may cause an error. If this should occur
it is NOT due to printer failure. It is caused by the in-
compatibility
of the software package with the newest
version
of the POSTSCRIPT Language.
QMS is committed to providing our customers with the
highest quality products. Thank you for your interest in
the
QMS POSTSCRIPT family of printers.

Laser Safety
This printer is certified as a Class 1 laser product under the U.S.
Department of Health and Human Services (DHHS) Radiation
Performance Standard according to the Radiation Control for
Health and Safety Act of 1968. This means that the printer does
not produce hazardous laser radiation.
Since radiation emitted inside the printer is completely confined
within protective housings and external covers, the laserbeam
cannot escape from the machine during any phase of user oper-
ation.
FCC Compliance
ii
This equipment generates and uses radio frequency energy. If not
installed and used properly, (in strict accordance with the man-
ufacturer's instructions) it may cause interference to radio and
television reception. It has been type tested and found to comply
with the limits for a Class B computing device in accordance with
the specifications in Subpart J of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interfer-
ence in a residential installation. However, there is no guarantee
that interference will not occur in a particular installation. If this
equipment does cause interference to radio or television recep-
tion, which can be detennined by turning the equipment off and
on, the user is encouraged to try to correct the interference by
one or more of the following measures:
(1) Reorient the receiving antenna. (2) Relocate the computer
with respect to the receiver. (3) Move the computer away from
the receiver. (4) Plug the computer into a different outlet so that
computer and receiver are on different branch circuits. (5) If

necessary, the user should consult the dealer or an experienced
radio/television technician for additional suggestions. The Fed-
eral Communications Commision has prepared a helpful booklet:
"How to Identify and Resolve Radio-TV Interference Problems".
This booklet is available from the U.S. Government Printing Of-
fice, Washington, DC 20402. Stock No. 004-000-00345-4.
A SHIELDED INTERFACE CABLE IS REQUIRED TO COM-
PLY WITH CLASS B LIMITS.

are NO user-serviceable parts inside.
Servicing should be done ONLY by qualified service per-
sonnel.
