Replacing the Printer Drive Assembly
To replace the printer drive assembly:
• If necessary, reinstall the gears. The gears are arranged on the shafts in the gear housing
as shown in Figure 5-6. Each gear has a number molded into it. That number corre-
sponds to a number molded into the gear housing next to the appropriate shaft. Insert
gears with molded numbers facing up.
• Pay special attention to gear #1. The top of the gear has a short lip molded close to the
teeth. The bottom of the gear has a taller lip molded next to the hole for the shaft. Make
sure the short lip and molded number face up.

the top cover.
