(16) Hold the Encoder Cover F with both hands, avoid the Tubes and insert it to the notch holes on the printer,
align the screw positions to the U flutes on the Encoder Cover F and slide it to the back end horizontally.

6-1-8. Replacing the CMYK Filter
GT-3 has four filters on the CMYK Print Heads, and the M/Y Filter for Magenta and Yellow needs to be replaced
regularly to keep the printer working in good conditions. (You do not have to change regularly the K/C Filters for
Black and Cyan.) When the warning appears on the Display [Exchange Filter (M or Y)], follow the instructions
packed in the spare parts “M/Y Filter” and replace to the new one and reset the warning message.
<Note>
Be sure to wear the gloves in operation to keep pretreatment from the skin, as well as to prevent the ink
contamination with dust and oil in the Tubes.
