2.2.4 Selftest
The selftest is performed in the STOP condition.
Test the following items.
Testing Procedure
1.
Perform the following test items while referring to “Performing a Self-Test” in the
DL1720E/DL1740E/DL1740EL user’s manual (IM701730-01E).
• Memory Test
• Keyboard Test
• Printer Test (only when the /B5 option is installed)
• Floppy Disk Test (only when the -J1 option is installed)
• PC Card IF Test (only when the -J3 option is installed)
2.
Confirm that all tests were completed normally and that no errors occurred.
3.
Perform the self-calibration, referring to “Performing Calibration” in the
DL1720E/DL1740E/DL1740EL user’s manual (IM 701730-01E).
4.
Confirm that “CAL” in the upper left part of the screen disappears, and that
calibration completed without errors.
