210 Troubleshooting at Organizational Maintenance Level
a. General. Organizational troubleshooting is performed by the
operator or unit repairman. Familiarity with the equipment will help in the
locating of some troubles and in making minor repairs. Any abnormal
performance must be checked, its cause discovered, and repairs made.
Repairs beyond the ability of the operator or unit repairman must be
referred to higher repair authority. When troubles occur, refer to the
equipment performance checklist (para 213) and to the general procedures as
outlined in paragraph 211.
211 Visual Inspection (figures 21 and 22)
Most defects that may occur in the printer may be detected by visual
inspection.
a. Examine the power cable to see that the connecting plug and
conductors have not been damaged.
b. Connect the equipment to a power source and move the power switch to
the ON position; the ruby safe lamp should light automatically.
c. Light the printing lamps by manually pressing down on the MOMENTARY
switch. If any of the printing lamps fail to light, try a replacement lamp.
d. Examine the masking blades, platen (front and rear) and platen
springs to see that they are not physically damaged.
