Recorder and Control
Block Checks
This check program checks the thermal array recorder and recorder control block
on the MAIN board without communication with the host CPU. Therefore, this
check is independent from the manual check menu.
This check allows you to inspect the quality of print, paper speed and feed, etc.
Procedure to start the Recorder and Control Block Check Program
1. To start the check program, press and hold the record key and NIBP
INTERVAL key until the monitoring screen appears when you turn on the
power. The SELF-TEST-PRO No.1 check program is ready for the execution.
2. To select one of the three check programs for the recorder and control block
checks, press the record key. Each time the record key is pressed, the check
program changes as follows:
SELF-TEST-PRO No. 1 → SELF-TEST-PRO No. 2 → SELF-TEST-PRO No. 3 →
SELF-TEST-PRO No. 1
3. To start the selected check program, press the NIBP INTERVAL key.
4. To finish these checks, turn off the instrument.
SELF-TEST-PRO No.1
This check program checks the peripheral circuits of the CPU for the recorder
control block on the MAIN board, e.g. ROM, RAM and DIP switch setting status.
The check result and recorder software version number are recorded on the paper as
shown below approx. 30 seconds after the NIBP INTERVAL key is pressed. The
recording starts soon after the black square on the paper is detected.
