7. Inspect the carriage shafts and the attached hardware. Look for damage, binds, or incorrect
installation.
Note: Do not lubricate the shafts.
You should find the carriage shafts to be clean. If the (small) carriage support shaft is coated with a
thick, viscous film, replace the carriage support shaft bushing. If the (large) carriage shaft is coated,
replace the carriage assembly.
8. Verify that the carriage shaft retainers and the sheet metal wear surfaces are installed correctly. The
retainers are installed correctly when the shafts are pinched into location on the printer side frames.
