Tractor Assembly Service Check
If there is a second tractor, it may be swapped for diagnostics.
The tractor assembly can be used for front push, or for rear push and rear pull configurations. To do this a drive
gear in the tractor assembly is placed in one of two positions by a motor. It is not necessary to remove the tractor
end cover.
The next figure shows a tractor assembly installed in the front push position with the gear in the drive position.
The tractor assembly idler gear is not used in the front push position. The printer front tractor drive gear is driven
by the paper feed motor through a drive belt.
