Lubrication Procedure 

General 

The 676 series printers are factory equipped with either composition bearings not 
requiring lubrication, pre-lubricated bronze bearings, or pre-lubricated needle 
bearings.  Periodic cleaning of the printer and removal of dust will greatly enhance 
the length of the time the printer will function. 

Composition (Iglide) Bearings 

1) If field replacement of an assembly fitted with a plastic bearing is performed, a 

single drop of spindle oil should be applied to assist in bearing break-in. 

2) If, after long use, a plastic bearing starts to "squeak", disassemble the component 

containing the bearing and lightly abrade the shaft surface.  Clean the bearing 
(dust or old oil) with alcohol, re-lubricate with 1 drop of light oil and reassemble. 

No other printer lubrication should be required in normal use.
