Replacement Procedure

5050/5100 User's Manual
The actuators for the 500-lpm and 1000-lpm models are physically
marked to distinguish them from lower speed model actuators. The
brazed block on the 500-lpm and 1000-lpm model has a black
connector housing. See Figure 7-3.

The handle on the actuator is used to lift the print head from the
printer. During installation, press down and to the right on the
barrels of the print head to position it properly.
Do not operate the printer with a print head removed. All 33
heads must be in place with their connectors secured so that
shuttle balance is maintained.
To remove and replace a print head, complete the following steps:
1. Turn the printer power off and disconnect the power cord from
the AC source.
2. Open the top cover and set the print gap wheel to the LOAD
position.
3. Remove the ribbon cartridge.
4. Tilt the control panel up and towards the front of the printer.
5. Starting with the middle one, unscrew the three captive
thumbscrews and remove the ribbon deck.
If the printer has been printing for an extended time, allow it to
cool for five minutes before replacing print heads.
