Troubleshooting
CADJET 2 4-37
11.5.4 Loaded Media Not Detected, Media Size Not
Detected, or Plotter Has Incorrect Plot Area
If the plotter doesn’t detect that media is loaded, doesn’t sense the
media size, or has an incorrect plot area, there are five possible
causes:
a. In some cases, the CADJET 2 will not sense or correctly size
certain media, whether roll-feed or sheet media. If this happens,
use the Manual Media Loading feature in the Advanced menus.
Refer to Chapter 2 of the CADJET 2 User’s Guide for the
procedure.
b. The optical sensor circuit (Paper Sensor) may be defective, or a
connector may be loose.
Go to the SERVICE DIAGNOSTICS
Menu and run DIAGNOSTICS PAPER SENSOR. You will need to
replace the Carriage Assembly if the Paper Sensor is not working
properly.
Refer to the Disassembly/Assembly procedures in
Chapter 5, Section 8.0.
c. The Slide Shaft may be set incorrectly. Check the alignment of
the Carriage. Refer to Chapter 6, Sections 6.0, 6.1, and 6.2 of
this manual for the Cartridge Head Height.
d. The Paper Sensor voltage may be set incorrectly. See Chapter 6,
Section 6.5 “Adjustment of the Potentiometer” for the testing and
correction procedures.
e. The Trailing Cable may be defective. See Chapter 5, Sections 8.5
and 8.6 for the removal and installation procedures.
