Learning Event 4: IDENTIFY METHODS OF TROUBLESHOOTING PROJECTION PRINTERS
Troubleshooting is the most time-consuming part of organizational maintenance because it involves
finding the part causing the problem, replacing the bad part, and then adjusting the printer so that it functions
a. Troubleshooting of the equipment at the organizational level includes the operational check
contained in the daily and weekly preventive maintenance checks and services charts, and the organizational
monthly preventive maintenance checks and services chart. To troubleshoot the equipment, perform all
functions starting with the first item and proceed through the items until an abnormal condition or result is
observed. When an abnormal condition or result is observed, refer to the organizational troubleshooting
chart (fig. 1-3) and perform the corrective measures indicated.
