Nozzle Bend and Nozzle Center Measurement
Carry out nozzle bend and nozzle center measurement on each nozzle before
actually entering production. These measurements are collectively referred to
as nozzle check. If nozzle check is not executed prior to production there is a
possibility that placement deviations will occur. Always perform nozzle check
prior to production.
Caution: When performing nozzle center measurement, a nozzle of at least 0.7
mm in diameter must be mounted at position 1 on all of the heads.
Procedure
1. Select [Nozzle Check] from the [Set Up] section in the [Main]
screen.
2. Select the items for which inspection is to be carried out from the
[Inspection Item] section.
Note: For black nozzles, only [Nozzle Length] inspection is to be carried out.
3. Select the nozzles for which nozzle check is to be carried out
from the [Holder] section.
Note: It is possible for multiple nozzles to be selected. Select [ALL] to select
all nozzles.
4. Select [Wide Camera] or [Narrow Camera] from the [Change
Camera] section in order to change the camera used to display
the status of the inspection results of each nozzle during mea-
surement.
5. Once the settings are complete, press [Start] in the [Holder] sec-
tion.
This will enable the the START button.

6. The nozzle check operation commences when the START but-
ton is pressed.
Notes: 1. Refer to the CP-842E/842ME System Reference manual for details
on nozzle check measurement.
2. Even when the above operation is not carried out, if the nozzle settings
for the current program differ from the nozzle settings of the program
used in production to that point, the differences in the nozzle settings
will be displayed and the nozzle check command will be entered auto-
matically at the time that automatic or step operation is entered. This
is referred to as the compulsory nozzle check function. Note however
that compulsory nozzle check may not function depending on the
Proper data setting.
Parts Set Check
Even after parts have been set on the machine, production cannot actually be
entered until the command used to verify that all parts have been set in the cor-
rect device slots has been executed. This function is referred to as device
check.
Procedure
1. Select [Device Check] from the [Changeover] section at the
[Main] screen.
2.
Verify that the device for a part with an [Unchecked] status is
properly set in the device slot, then select that part’s display.
3. Press [Set Devices] at the [Check] item.
The “Unchecked” status changes to a “Parts Available” status.
