This training course covers operation and maintenance
of the Model 8000 Medium Speed Printer.
The Self Study Course is designed to be used for self
paced instructions and makes maximum use of the information
contained in the MSP User/Maintenance Manual.
The Model 8000 Medium Speed Printer can serve you no
better than your ability to use and maintain it properly;
so study the course thoroughly, then keep it for periodic
review.
This course consists of four units of study including
both written and practical assignments designed to
first, have the student become familiar with the Model
8000 MSP controls and equipment locations, then perform
practical exercises to gain operational efficiency.
The units of study are structured to be used with the
four sections of the MSP User/Maintenance Manual.

to include Preventive Maintenance, fault isolation
(using Self Test), and repair of the MSP by replacing
the defective LRU.
Each unit of the course consists of a statement of
objectives, frames of instruction, and a quiz or performance
task. The objectives will tell you what you will be
able to do when you complete the unit.The frames of
study contain the information you must learn. The quizzes
and task performance exercises will help you and your
supervisor to assess your progress, and guide you to
those frames that you must review if you did not select
all of the correct answers or perform all elements
of the tast.

Verify that the MSP is operating properly be performing
a self test, checking the paint quality, internal and
external LEDs and lamps, and that the MSP receives
data (from "line" or a generator source). Once you
have established that there are no faults in the MSP,
insert one fault (from the list provided) into the
MSP and verify the symptoms. Describe symptoms to student
(written or orally.)
Monitor student performance throughout this exercise
to ensure compliance to accepted safety practices and
to the procedures listed in this section and in the
manual.
Once the student has successfully located the faulty
LRU, remove the fault.
S̲t̲u̲d̲e̲n̲t̲.̲ Locate the faulty LRU and replace it using
procedures in the MSP User/Maintenance Manual and in
this section.
This exercise should be used repeatedly, inserting
a different fault for each repetition.
5.2.4 F̲A̲U̲L̲T̲ ̲I̲S̲O̲L̲A̲T̲I̲O̲N̲
S̲e̲l̲f̲ ̲T̲e̲s̲t̲.
Although the self test does not check all the circuitry
in the MSP, it does test the more complex circuits
such as RAM, ROM, and clock/timer circuits. Therefore,
whenever possible, a self test should be accomplished
as the first step of any MSP troubleshooting procedure.
The following is a list of circuits checked by the
self test programs:
Read Only Memory (ROM) on CPU CCA
Random Access Memory (RAM) on CPU CCA
Clock Timing Circuit (CTC) on CPU CCA
Parallel Input/Output (PIO) on CPU CCA
Universal Peripheral Interface (UPI) & Decoders on
Printer Interface
Transmit and Receive Data Lines & Baud Rate Generator
on Signal Interface
S̲e̲l̲f̲ ̲T̲e̲s̲t̲ ̲E̲r̲r̲o̲r̲ ̲C̲o̲d̲e̲s̲.
When a failure is detected by the self test program,
the printer will print the error number for that failure,
the circuit card location of the failure, and the subassembly
reference designator that should be replaced to correct
the problem;

Other Procedures
Certain failures within the Medium Speed Printer will
inhibit the self test function, for instance a loss
of + 21 VDC will inhibit printer operation. Thus, the
self test pattern would not be printed nor would the
fault be identified by self test. However, most faults
of this nature can be isolated to the subassembly level
by a visual inspection and by using the fault isoslation
flow chart. A visual check of the five light emmitting
diodes (2) on the Printhead Driver (A1) and (3) on
the Signal Interface (A10) provice an excellent starting
place for isolation of power supply related faults.
After having accomplished the directions provided by
self test and the problem still exists, perform the
actions listed in the fault isolation flow chart located
in this section.
Upon locating and replacing the faulty LRU MSP checkout
may be accomplished using MSP Checkout Procedures contained
on next page.

The following steps should be performed after completing
maintenance on a unit, upon receipt of a unit from
supply system, and may be used to gather the information
to assist in an effective fault isolation procedure.
a. Ensure printer paper and ribbon is installed and
ready for printer operation.
b. Open TCM cover.
c. Make sure all cables are connected.
d. Set TCM power switch to "ON" position.
e. Listen for fan operation.
f. Ensure the following LED's (5) are illuminated.
1) DS1 on Signal Interface (A10) - + VDC Indicator
2) DS2 on Signal Interface (A10) - + VDC Indicator
3) DS3 on Signal Interface (A10) - - 21 DC Indicator
4) DS1 on Printhead Driver (A1) - - 21 DC Indicator
5) DS2 on Printhead Driver (A1) - + VDC Indicator
g. Close TCM cover.
h. Check for proper line feed operation. Depress "Line
Feed" button for longer than 2 seconds: One Line
Feed; pause, continuous Line Feed.
i. Check for proper Form Feed Operation. Depress "Form
Feed" button: Printer paper moves to same line
on next form.
j. Depress "Test" button and TCM front panel. Make
sure all front panel indicators illuminate.
k. Continued holding "Test" button depressed until
SELF TEST feature is initiated, approximately five
seconds. A self test (barber pole) pattern is printed.
Ensure print quality is good.
l. Set TCM Power Switch to "Off" position. If a fault
is noted during checkout procedure, locate and
repair the defective LRU by using Self Test directions
or the fault isolation flow chart.
