Sram Check; Dram Check - Muratec MFX-2500 Field Engineering Manual

3.11.5 SRAM Check

This mode is used to test the SRAM memory where user programmed parameters such as date, time,
TTI, etc are stored.
Note: When this test is executed, All RAM Clear will be performed by the machine.
The All RAM Clear erases all user settings and resets all memory switches, machine parameters and
unique switches to factory defaults.
1. Press MENU, *, B.
2. Select "E. SRAM Check" by cursor key, then press [Enter].
3. Enter the HEX code (00 ~ FF), then press [Enter].
The HEX code is written to, then read from, memory. After that, the result (OK/NG) will be shown in the
display. Then the machine will return to standby.

3.11.6 DRAM Check

This mode is used to test the DRAM memory, or document memory.
Note: When this test is performed, All DRAM Clear will be performed by the machine. The All RAM clear
erases all user settings and resets all memory switches, machine parameters and unique switches
to factory defaults.
This is a read/write test that requires a few moments to complete.
Note: Perform a DRAM test whenever a memory upgrade is added to the machine.
1. Press MENU, *, B.
2. Select "F. DRAM Check" by cursor key, then press [Enter].
3. Enter the HEX code (00 ~ FF), then press [Enter].
