The following table lists problems that may occur on the unit (operations and functions) with description of the symptoms,
their possible causes and remedies.
Never replace parts to repair or modify the unit. Not only does it fail to repair or modify, but
it also may cause electric shock or damage to the unit.
Symptom
Cause/Remedy
(1) Unit does not function even the
power switch is turned ON
(1) Check the wiring to the power terminal.
(See “4-3.3. Power/protective conductor terminals wiring”.)
(2) Make sure that the power voltage is AC100 to 240V.
(2) Noise produced as printer
moves
(1) Check if the cartridge pen is attached properly.
(See “6-1.2. How to set plotter pen and cartridge pen”.)
(2) Open the unit door and check the printer moving area for foreign
matter. Remove it if exists.
(3) Data displayed but not
recorded
(1) Make sure that the recording is ON (“REC” status LED lights up).
(See “6-2.4. Chart recording operation”.)
(2) Check if the ribbon cassette is attached properly.
(See “6-1.2. How to set plotter pen and cartridge pen”.)
(3) Check if the chart is attached properly or if it has run out (“REC”
status LED flashes).
(See “6-1.1. How to set chart paper”.)
(4) Chart does not move as printer
moves

When a setting is changed while the chart recording is ON, a setting
change mark is printed on a chart. Check the chart to see if it is
printed.
If not, the following situation is a possible cause.
You have not pressed the
key after moving the cursor to

(2) Parameters are not set correctly.
(See “8-10 and 8-11. Periodic Data Printing Settings”.)
* When you specify a start time which is earlier than the time of
setting, periodic data printing will be executed from the next day at
the specified time.

unpredictably without warning
Initialize setting parameters.
(See “8-26. System Settings”.)
When the unit is recovered, set parameters again and see how it
