Chapter 2 Principles of Operation
2.2 MECHANICAL OPERATION
2.2.01 Paper Feed
Paper feeding is performed by the large and small feed roll assemblies, which are driven by the paper
feed motor assembly and the pick roll assembly.
At the beginning of the paper feed operation, the paper feed motor reverses momentarily to allow the feed
arm pawl to drop off the home position notch in the left side frame.
If the pawl fails to drop off the notch, check the feed arm assembly for binds, worn parts, and or broken
parts.
After the paper exits from the feed rollers, the paper feed motor reverses.
This causes the paper ejectors to move the last sheet of paper into the exit tray.
If the ejectors do not move or restore, check them for worn, loose, or broken parts.
Be sure that the ejectors are connected to the large feed roller shaft.
The pick roll assembly performs the manual feed process.
The large and small feed roll assemblies perform the auto feed process.
