DMP-134  (260-2848)       Buffer and Ram Upgrade       Faxback Doc. # 4523

The DMP 134 can download 64 draft-quality characters with the standard
8K-byte RAM.  However, if you want to download the NLQ characters
and/or more than 64 characters in either draft or NLQ font, you will need 
the optional 32K-byte RAM (260-2851) available by special order from your
local Radio Shack store.

We strongly recommend that you have the RAM installed by the service 
technician at your Radio Shack Service Center. Doing so not only ensures 
expert installation, but also enables the technicians to quickly check to 
be sure all the functions are operating properly.

If, however, you do decide to install the RAM yourself, follow the steps 
detailed here exactly.

To install the RAM:

The RAM chip should be installed in the P3 socket.

1.  Open the printer cover and remove the ribbon cassette.

2.  Manually move the print head to the right.  

    Caution:  If you have been printing, allow the print head to cool
    down before touching it.

3.  Grasp the fin of the compartment cover on the mechanical frame and
    slide it to the left to remove it.

4.  Insert a flat-blade screwdriver into the gap between the RAM IC
    and the IC socket.  Gradually pry one side and then the other,
    alternating back and forth until the IC comes out of the socket.

5.  Unpack the expansion RAM from the box and insert it into the IC
    socket so that the mark on the RAM aligns with the mark on the IC
    socket.

    Caution:  Be careful not to bend the pins of the RAM chip.

6.  Replace the compartment cover, ribbon cassette, and printer cover.
