Epson M X - 8 5 Printer User Manual


 
2. Self -Test
The MX-85 has a self-test routine programmed into the Controller. It is useful to
check the operation of the print head and the print mechanism (ribbon, motors, belt,
etc.). The input connector is not checked with this test.
1.
Be sure there is an adequate supply of paper in the Printer. The test requires about
22 inches.
2. Turn’off power.
3. Turn on power while holding the LF button depressed.
4. The MX-85 will begin printing its test pattern. The LF button can be released after
printing commences.
NOTE:
See Appendix C for Character Fonts.
If any problems are encountered at this point, contact your vendor for correction
before proceeding.

3. On-Line Operation
Connection to your host system is through the 25-pin EIA connector located on the
left rear of the MX-85. The pin assignments are noted in Table 8. It is recommended
that all interface cables be as short as possible to minimize noise injection.
