1) No printing is executed. • Check if the printer is turned off. See Section 6.2.

• Check if the cassette ribbon is mounted normally.

2) Digital printing is not executed. All digital printings are not executed if the chart speed is programmed

to be faster than 150mm/h. See Section 10.2.

3) Printing color is pale. Replace the cartridge pen or the plotter pen.

4) Chart paper feed is abnormal.

• Check if the chart paper is unlatched from the sprocket.

• Check if the chart paper cassette is securely inserted into the

internal unit.

• Check if the chart paper has been shuffled before loading it.

5 Other Troubles

Symptoms Causes and remedial measures

1) Keys are not acceptable.

2) Parameters cannot be changed. Keys are locked. Unlock them. See Section 11.12.

3) Prarameters remain unchanged

after changing them.

To store parameters to be programmed for each channel, press

and simultaneously. If not, parameters are not

stored into memory. See Section 8.2 and other sections for

programming.
