Two  retaining  pins  are provided  with  the printer  kit.  Operators  must  install the  retaining  pins when  the  printer  hood  is
open and the operator is performing printer maintenance tasks. Pin installation locations are at the left (LH) and right (RH)
sides of the printer and are installed to prevent the printer hood pistons from closing. 

How-to Video:

         

1.

The LH pin installation location is shown in 

Figure 1-1

.

2.

Open the printer hood and insert the retaining pins into the LH and RH pin sockets.

3.

Ensure the retaining pins are inserted fully into the sockets, and proceed with any required maintenance tasks.

4.

Remove the retaining pins after completing tasks.

1.4

Using Retaining Pins

Warning:  The Printer Hood represents a CRUSHING hazard when open. To prevent Operator injury, always 

install the Retaining Pins when the Printer Hood is open while performing printer maintenance 

tasks. The Retaining Pins are intended for the personal safety of the printer operator to prevent 

the Printer Hood from lowering due to operator error or system failure.
