Cleaning the Ultrasonic Multi-feed Detector
CAUTION:
Do not use canned air to clean the ultrasonic
multi-feed detector transmitter and receiver as this
could blow debris into difficult to clean areas of the
scanner.
A dirty transmitter or receiver can result in “false
paper jam” errors. Use the following procedure to
clean the transmitter and receiver.
1.
Obtain an “ear syringe” or “nasal aspirator” from a
local drug store.
2.
Open the scanner cover as described in “Opening and
Closing the Scanner Cover” on page 87.
3.
Locate the ultrasonic multi-feed detector transmitter
and receiver. The receiver in the cover is shown
below. The transmitter is housed in the base of the
scanner directly opposite the receiver when closed.
4.
Use the ear syringe or nasal aspirator to blow (with air
only) any debris from the transmitter and receiver
areas.
