Linx 8900
Shaft encoder connection
You must use a 9-pin, D-type connector to connect the shaft encoder to the printer. The
following table describes the function of each pin.
Connect the screen of the shaft encoder cable to the shell of the connector. The connector
shell must connect to the printer chassis. Do not connect the screen to 0 volts.
To maintain the IP55 rating of the printer, the connector of the shaft encoder must have at
the minimum an IP55 rating. Linx shaft encoders have a D-type connector that has an IP65
rating.
CAUTION: Use only Linx-approved accessories. The EMC performance of the printer
can change if you use other shaft encoders and cables.
Calculate the encoder pitch
If you use a shaft encoder, the printer can calculate the encoder pitch for you. Refer to
‘Calculate Line Speed/Calculate Encoder Pitch’ on page 58 for more information about how
to calculate the encoder pitch.
Check the print samples for performance. If necessary, you can use the Print Width option
to make small adjustments to the horizontal distance between ink drops in a message
character. Refer to ‘Print Width’ on page 80 for more information.
If you do not follow the calculation, your messages are not printed at the required size. The
spaces between the ink drops in a message are too small or too large.
