Tractor 2 Service Check - Lexmark 4227 - Forms Printer B/W Dot-matrix Service Manual

Tractor 2 service check

The Tractor 2 sensor opens during installation, when its actuator
touches the printer cover. The home sensor detects the position of
the slider.
•
When Tractor 2 is selected, the motor-driven Tractor 2 slider
pushes the printer sub slider cam lever to engage the printer
gear train, which drives the Tractor 2 tractors.
•
When the Tractor 2 is deselected, the motor retracts the slider,
disengaging the Tractor 2 gear drive and reengaging the printer
tractors.
63D Tractor 2 HP error
The Tractor 2 Home sensor was never initialized after turning the printer off
and then on, or made at the wrong time.
(The same error indication is used for carrier home failure.)
