Appendix F: Transferring

Power to Pin 18

To transfer power to pin 18 of the parallel input connector of the PQ-8P, you must move a jumper on the PQ-8P board. To move this jumper do the following:

1.Power off the printer, the PQ-8P, and the attached PC or LAN print server.

2.Disconnect all cables from the PQ-8P.

3.Remove the two black screws from the outside of the back panel.

4.Pull out the PQ-8P’s back panel, together with the attached board.

5.Locate the jumper in the lower left corner, right above the parallel connector labeled “Parallel In From PC/LAN” (see Figure F-1).

6.Remove the black jumper from the pin, then reinsert it covering both pins (see Figures F-1aand F1-b).

7.Slide the PQ-8 board back into the bottom groove of the chassis.

8.Tighten the black screws on the back panel.

9.Connect the printer and the PC/LAN to the PQ-8, then connect the power cord.

10.Power on the printer, then the PQ-8.
