Precautions When Installing Printer Accessories
Disconnecting the Power Cord:
Never remove the control board while the printer is plugged in.
To avoid the possibility of an electrical shock, always disconnect the power cord when installing or removing ANY internal or external printer option.
Discharge of Static Electricity:
The control board and internal printer memory are sensitive to static electricity. Before installing or removing an internal printer memory, discharge static
electricity from your body by touching something metal on any device plugged into a grounded power source. If you walk around before finishing installation,
discharge any static electricity once again.
Installing Printer Memory
Additional printer memory is provided on a Dual In-line Memory Module (DIMM).
Your printer has 92 MB of memory. It can be expanded to 192 MB. Remove the preinstalled memory DIMM before upgrading the memory.
1.
Power the printer off and unplug all cables from the printer.
2.
Grab the control board cover and open it.
3.
Completely open the latches on each side of the DIMM slot and remove the preinstalled memory DIMM.
