Real-Time Clock Installation Guide
Figure 1. Removing the Left-Side Cover of the printer
GL4xxe Real-Time Clock Installation
Before installing the Real-Time Clock chip, make sure the printer is OFF and
disconnected from the power supply. Make sure you have discharged any static
electricity (by touching a grounded component on the printer). Remove all interface
cards prior to removing the rear side cover.
1. Use a Phillips head screwdriver to remove the three screws (1) that secure
the left-hand side cover [labelled (2) in the illustration below] that protects
the electronics of the printer.
2. Slide the side cover leftward and upward, as shown by the line marked (a).
3. Once the cover has been removed, locate the area circled in RED. There is
an empty socket for mounting the Real-Time-Clock chip.
