Base Printer Sensor Tests
The base sensor test is used to determine whether or not the
sensors located inside the printer are working correctly. All sensor
tests are contained under the same menu and they are separated
into the following groups:
• Engine/Printer
• LCC/2500-Sheet Optional Paper Drawer
• Finisher
• Mailbox
Each of these categories can be selected as a sub-menu of the
BASE SENSOR TEST menu in diagnostics. When selected, a
binary value displays on the panel. Each bit of that binary value
represents a sensor. A zero-valued bit indicates that particular
sensor is closed, while a one-valued bit indicates that particular
sensor is open. When checking to see if a sensor is working
correctly, look for a digit change on the display as each sensor is
individually activated.
