1.7. Memory Expansion Installation
In this section is explained how to expand the printer's memory. Expanded printer memory enables you to
print more complex pages, download more fonts, and define more macros.
It begins by explaining how to remove the main circuit board from the printer, and explains how to install a
SIMM (single in-line memory module) on the main circuit board.
The DP-1400 comes supplied with 8 MB of memory installed, and likewise the DP-1800 comes with 16 MB
of memory supplied. Two slots are provided for expanding the memory in your printer so that more complex
printing can be done, as well as increasing the printing speed. By installing optional memory cards into your
printer, the memory in the DP-1400 can be increased to a maximum of 72 MB, and the DP-1800 can be
increased to a maximum of 64 MB.
☛
!
A 16 MB SIMM is installed in one of the SIMM sockets in the DP-1800, so in order to increase the
memory to the maximum 64 MB this SIMM must be changed.
!
The expansion memory should be installed only by an authorized dealer or an certified techni-
cian. We shall not be liable for damage due to improper installation of the expansion memory.
The minimum memory requirements for the printer with various options installed are listed in the table
below. Please refer to this table when expanding the printer's memory.
Removing the Main Circuit Board
The main circuit board of the printer is equipped with two sockets for memory expansion. Expansion mem-
ory is available in the form of a SIMM.
☛ The following instructions are intended for the technician only.
Notes on Handling the Main Circuit Board and SIMM
Protect the electronics by taking these precautions:
❒
Before touching the main circuit board, touch a water pipe or other large metal object to discharge
yourself of static electricity. While doing the work, it is recommended that you wear an antistatic
wrist strap.
❒
Touch the main circuit board and SIMM only by the edges.
WARNING
When adding memory, ALWAYS remove the power plug from the outlet. If this operation is performed with the power still
attached, there is a danger of electrical shock.
