“2-4-2. Cleaning the paper feed inlet sensor”
“2-5-6. Cleaning the paper ejection outlet
sensor”
Check that the fixing screw of the Z collar of the slide
stopper is not loose.
Remove paper dust near the female screw groove on
the screw shaft and the home sensor, and apply a small
amount of oil to the bearing.
The area where the screw shaft and the full nut are
connected cannot be applied with oil or grease.
3-2. Other General Precautions
3-2-1. Oiling
Apply the specified oil to the following locations.
Area where shaft and bearing are connected (sintered bearing)
Specified oil: Orelube G90-140 (Equivalent to ISO #460)
Make sure no oil adhered to the contact surfaces of the armature and rotor of the electromagnetic clutch,
and area where the screw shaft and full nut are connected.
NoteNote
3-2-2. Greasing
Apply the specified grease to the following parts.
Gear teeth, paper feed tray automatic up/down drive rack related parts, etc.
Specified grease: Orelube G1650 (Equivalent to NLGI #1)
Plate spring for grounding conduction of folding roller
Specified grease: Dow Corning MOLY KOTE 41 (Conductive grease)
Make sure no grease adhered to the contact surfaces of the armature and rotor of the electromagnetic
