Cleaning the Encoder 5-13
Cleaning the Encoder
Maintenance interval: at Maintenance Clock Alarm.
The encoder strip allows the printer to precisely locate the print-
head carriage across the width of the platen. If the encoder
becomes dirty with paper dust or ink, the printer cannot print
accurately, and print quality will suffer.
The encoder strip
➊
is a clear plastic strip, imprinted with a pre-
cision encoding pattern, and mounted horizontally along the
rail
➋
. To clean the encoder strip, use a can of compressed air,
sold at camera or graphic supply stores, to blow dust and other
particles from it.
