This trainer is part of Labtech's Computer Information Technology (IT) training system. Each trainer
is designed to instruct service technicians in the operation, theory, servicing, problem diagnosis and
repair of the key technologies as found in IT today. All of the trainers are based upon real computers
and peripheral devices which have been modified to facilitate training and have a special electronic
fault insertion system.
This trainer is based upon a popular brand printer which has been specially modified to allow easy
access to the internal parts and components. Circuit boards feature plexiglass covers which have
opening for access to all test points for instrument readings. The trainer allows access to all the
factory recommended key points for the taking of measurements for analysis and adjustment.
Trainer includes standard power cord and standard parallel cable for connection to an IBM
compatible computer.
The teaching program is designed to follow the service procedures as recommended by the
manufacturer and uses the factory service manual in conjunction with student job sheets. The
course emphasizes operational components of the system and troubleshooting and Diagnostics. Each
trainer comes with complete courseware as follows :
a) Factory service manual with detailed circuit board schematic diagram.
b) Student job sheets with fault guide and wiring diagram.
A unique fault insertion system is built into the trainer for student instruction purposes and includes
10 faults. The system features a Schematic Block Diagram silkscreened onto an integral fault board
that utilized LEDs to indicate the nature and location of the fault. The fault is activated by touching
an electronic switch with a special teaching probe. Single or multiple faults may be introduced at any
time. Activated faults are visible as the corresponding LED illuminates on the fault board. The LEDs
can also be switched off thereby not allowing the student to know where the fault is, this feature is
ideal for testing the student's trouble shooting ability.
