THE INTERLOCK CIRCUIT

INITIALIZING THE PRINTER

When to Initialize

5050/5100 User's Manual
This printer has an interlock circuit to meet safety and international
requirements.
The interlock switch circuit disables the power supply voltage when
the ribbon deck is lifted. This eliminates any potential shock hazard
or inadvertant printer start-up while moving parts in the print area
are accessible. The ribbon deck must be in place and all three
thumbscrews must be tightened securely for printer operation. See
Figure 2-27.
Removing the ribbon deck with the power applied will energize
the interlock circuit. If this happens, the deck must be replaced,
power must be turned off for a period of 5 minutes before
attempting to reapply power.
THUMBSCREWS ON RIBBON DECK
Initializing resets the printer electronics and sets the printer
parameters to factory defaults. Parameters include margins, tabs,
forms control, characters per inch, lines per inch, etc.
Initialize the printer when:
▪ It is desirable to reset the printer to the factory default settings.
▪ After new software has been installed.
▪ Repair actions involving the logic circuit boards have been made.
