Chapter 9 Label-Taken Sensor

Description

The LTS circuit board is fitted inside a plastic casing attached to the
centre-line wall by means of two snap-locks. The cable running
from the LTS circuit board goes through a shallow gap in the centre-
line wall into the electronics compartment, where it is connected to
J4 on the CPU board.

Replacement

In case of a defect LTS module, do not try to repair it but replace the
entire module.
• Turn off the power to the printer and remove the power cord.
• Open the front cover.
• Remove the electrics cover (see chapter 2.3).
• Disconnect the connector from J4.
• Jerk the LTS casing up and down to disengage the snap locks.
• Fit the replacement LTS module in reverse order.
