■ 4 MB Memory Upgrade Module
A single printer shared by many users often requires a 4 MB
upgrade. It expands the printer’s memory to allow for
sophisticated forms and graphics, and for many fonts.
Installing Memory Upgrade Modules
Memory modules contain electrical components which are
extremely sensitive to static electricity. If possible, wear an
anti-static wristband during the install procedure. Otherwise, before
removing the board from the anti-static bag in which it is packaged,
hold the bag while touching any base metal surface on the rear of
the printer. Avoid walking about, especially on carpet. Handle
the board carefully, and try to handle it only by the edges.
Read all the instructions carefully before beginning and make sure
you understand them. The only tool necessary is a small Phillips
screwdriver.
1. Turn the printer off and remove the power cord. Disconnect
all interface cables (parallel, serial, and LocalTalk) from the
printer.
