FAX-L1000 Chapter 1: Safety and Precautions
2.3.2 Lubrication points
Do not touch the greased parts. If you do, the grease (applied for smooth operation of the
printer mechanism and to increase electrical conductivity) will come off.
Use only specified grease.
If you use other grease, the grease may oxidize, and weaken plastic parts.
REFERENCE
If you accidentally touch a greased part and grease comes off, reapply the
grease, see the
PARTS CATALOG (supplied separately) .
2.3.3 Scanner section
a) Contact sensor
Handle the contact sensor carefully to avoid scratching or dirtying its scanning surface.
Scratches or dirt on the scanning surface can cause vertical stripes or other defects to appear
in the scanned image.
Also, if the contact sensor scanning section is exposed to external light for prolonged
periods, its characteristics deteriorate, resulting in blackish scanned images. During
servicing, do not expose the contact sensor scanning section to external light for prolonged
periods.
b) Auto document feeder (ADF) rollers
Handle the ADF section rollers to avoid scratching or dirtying them. If they are scratched or
dirtied, vertical stripes or other defects may occur in the scanned image and the document
may jam.
If the roller is dirtied, clean it with a soft, dry cloth.
c) Plastic film
Do not modify the plastic film (white sheet unit) which presses down the document in the
middle frame unit of the reader assembly.
Document jams may occur if it is modified.
d) Stamp Ink supply
Fill with one drop of stamp ink so that it does not overflow the edge of the stamp. The
operation of the stamp may be degraded if the ink overflows and drips down.
e) Middle reader frame unit stopper
Do not force the middle reader frame unit open with the stopper removed. If unnecessary
strength is used, the hinge of middle reader frame unit will be damaged.
