1. GENERAL
1.01
This part provides routine maintenance
procedures for the
43 Teleprinter Buffered
KSR Terminal.
1.02 A routine maintenance should be per­
formed, at the convenience of the cus­
tomer, at least once a year.
1.03 Routine maintenance consists of visual
checks, lubrication, and cleaning. When
performed at routine intervals, the possibility
of later troubles will be reduced.
1.04 Following the routine maintenance, a
local and on-line installation checkout
should be performed. (See Page 1-43.) The routine
maintenance date should be filled out on the
bottom side of the directory card holder.
2. VISUAL CHECKS
2.01 The following areas should be checked for
mechanical condition:
(a) Frayed belts on spacing and line feed
motors
(b) Worn or frayed ribbon
(c) All cable connectors fully seated
(d) Print head cover fully seated
3. LUBRICATION
3.01 Lubrication of the printer is required
during routine maintenance. Refer to
Page 2-19 for type, location, and amounts of
lubrication.
4. CLEANING AND APPEARANCE
4.01 Examine exterior areas for smudges, dust,
etc.
4.02 Check proper fit of cover. Replace ex­
tremely damaged or discolored cover,
housing, bustle, etc.
4.03 Exterior cleaning should normally be
limited to wiping with a soft cloth moist­
ened with a mild detergent. However, in case of
ink stained plastic surfaces, a waterless (nonabra­
sive) hand cleaner or a lather from abrasive bar
soap applied with a cloth should be used.
4.04 Interior areas should be examined with
the cover opened and accumulations of
paper dust or ribbon fragments cleaned by care­
fully brushing loose material onto a cloth. Ink
stains or deposits on interior surfaces, ribbon
rollers, platen, etc, can be wiped with a cloth
dampened in mineral spirits.
WARNING: Do not allow solvents to contact
interior, exterior or any component plastic
surfaces.
