7. Troubleshooting

The printer does not operate properly

The M252A is not connected to a power source.

Check that the power cord is fixed properly.

If the power LED does not light even though the M252A is connected to a power source,

the fuse may have blown.

Since the fuse has been installed inside the M252A, disassembly is necessary for

replacement. Therefore, it should be replaced by UNIPULSE. Consult your dealer
representative or UNIPULSE.

Printing is not generated until the data input terminals (SI/F, BCD input, RS-232C) are

connected properly and print data is sent.

Check to see if the connectors are inserted properly, and check for broken wires and

miswiring.

Check that the equipment sending data to the M252A (indicator sending SI/F signals, PC

sending RS-232C signals, etc.) operates normally.

In the case of a connection through the BCD input, check that the M252A and target

equipment are consistent in logic.

In the case of a connection through the RS-232C, check that the M252A and target

equipment are consistent in communication conditions. Settings that must be consistent
include transmission rate, character length, start bit, stop bit and parity bit.

Printing is not generated if the Print Every ON/OFF setting is OFF.

Make the Print Every ON/OFF setting at ON.

The M252A does not start.
