Initial Actions Procedure
Purpose
The purpose of the Initial Actions section of the Service Call Procedures is to determine the
reason for the service call and to identify and organize the actions which must be performed.
Procedure
1. Gather the information about the service call and the condition of the copier/printer.
a. Question the operator(s). Ask about the location of the most recent paper jams. Ask
about the image quality and the general performance of the copier/printer, including
any unusual sounds or other indications (if applicable).
b. Check that the power cords are in good condition, correctly plugged into the power
source, and free from any defects that would be a safety hazard. Repair or replace
the power cords as required. Check that the circuit breakers are not tripped.
c. Ensure that all paper trays are loaded with paper.
d. Inspect any rejected copies. Inquire as to, or otherwise determine, the paper quality
and weight. The specified paper for optimum image quality for the Phaser 790
Printer is Hammermill Laser Print 24. The specified paper for optimum image quality
for the DC 2006 Copier/Printer is 24# Xerox COLOR Xpressions or Colotech + 90
gms. Look for any damage to the copies, oil marks, image quality defects, or other
indications of a problem.
e. Record the billing meter readings.
f. Check the Service Log for any recent activities that are related to the problem that
caused the service call or any secondary problem.
2. Check the Image Quality by performing the Visual Calibration (GP 16).
a. Run four copies of the 82E13030 Test Pattern.
b. Check the image quality. If the customer has identified any Image Quality Defects or
problems, go to the IQ1 Image Quality Entry RAP.
3. If there is a problem in the Basic Printer Mode, go to the Call Flow Procedure.
4. If there are no problems in the Basic Printer Mode, go to the Final Actions.
