7.3 HOW TO CLEAR HISTORY DATA
Clearance of various logs after the Assys are replaced
(1) Clearance of logs, using the RS-232C commands
Besides adjustment data, data on accumulated power-on time and logs on defective parts of the product are backed up. Some
of those data must be cleared after the Assys are replaced for service.
Notes: •
As the pulse-meter count is used for each correction function, it must be cleared when an Assy relevant to
correction functions is replaced.
•
When clearing logs, using the RS-232C commands, first enter Factory mode (by issuing FAY or PFY), then issue
the corresponding command.
