LEANING AND
UBRICATION
A certain amount of dust from the metallized coating of the paper will accumulate within the printer as
printing proceeds. Whenever the printer is dismantled for any reason, the dust should be removed, using
a gentle airblast and/or a soft brush.
Never use solvents or other fluids as they may attack the plastic or rubber components.
Before re-assembly of the printer, bushes should be lightly lubricated with Molycote 44, but gears,
wormshafts etc., must not be lubricated; a thin coating of electrolube should be applied to the conductor
strip in the top cover assembly.

on the conductor strip in the underside of the cover.
d) Withdraw the cover, and lift off the operating button for the button feed switch.
e) If the serrated tear-strip is worn or damaged, this can be removed by pushing out the centre lug
