Comment
1.1 Device Info: Serial
number and
Installation date
Compare device serial number to section 11
“Technical Standard Modifications” and
section 13 “Field Service Bulletins” to determine
whether the device is modified or requires a
modification.
1.4 Software Info It is recommended to have the latest software
installed. Before you upgrade to a new software,
make sure that your hardware is up to date.
2.2 Throughput For throughput most important are the cycles per
day. They usually count between 50 and 200.

DD+DIS013.02E Maintenance
Edition 1, Revision 10 ADC Solo Section 12 / 5
(Type 5155 / 100/200)
3.3 Hardware
Modification History
By comparing the status of the device with the
available “Modifications”, section 10, the exact
hardware status can be determined.
3.4 Software modification
history
By checking the software modification history it
can be determined, whether a recent software
upgrade solved a problem, that occurred quite
often in the error list.
4.6 Laser power Check that laser power is constant: no more than
1mW difference in between two entries. If the
value is higher, run diagnostic software and
scan&signals and check laser diode module.
4.7 Galvanometer
Monitoring
Check the entries. If the limits of offset (30) or
amplitude (60) are exceeded, check the last
images on the workstation thoroughly for jitter.
Change galvo only if necessary.
5.3 Retries Many retries (> 1%) have to be investigated:
They usually lead to less throughput of the
device. Compare it with frequent error codes.
5.7 Error History Check the last occurred errors (in between two
maintenance), how often they appeared as well
as the CBF (cycles between failures) of these
errors. This gives an overview of the current
status of the machine.
Compare frequently occurring errors to the error
hit list, section 6.3, and take actions.
5.8 Error List Relatives
and
5.9 Error List Total
Troubleshoot these errors with the help of the
technical documentation, section 6.3,
“Troubleshooting”.
3.1.4 Clear Infocounter
(1) Clear the infocounter to refresh relative counters.

4.3 Evaluation of a Flatfield
(1) Inspect the developed image for homogeneity:
Compare the prints of the flat field sample with your exposed flat field at a
light box.
•If there are no lines visible or the effects are less than on the example,
the image quality is all right.
•If there are unacceptable effects, compare with the following sketches.
Calibration lines
Blurred dark lines in slow scan
direction on the flat field (see
beside).
•Expose another flat field and
compare it again with the
sample.
If there are still unacceptable
effects, you have to redo shading
calibration as described in section
6.6.
Expose another flat field and
compare it again with the sample.
If there are still unacceptable
effects, please contact the Support
Center.
