5.2 Adjustment Steps

This section describes the detailed steps for performing the adjustment procedures listed in
Table 5-2.

5.2.1 Parameter Backup

NVRAM (Flash-ROM and EEPROM) are installed on this printer's C299MAIN board and
the "Backup Parameters" are recorded in this memory.
The backup parameters consist of "Panel setting values," "C299MAIN board inherent
adjustment values (cannot be erased or changed)" and "Mechanism adjustment values."
During servicing, if operations which include replacement of the C299MAIN board are
performed, the "Panel setting values" and "Mechanism adjustment values" included in
these backup parameters on the existing C299MAIN board should be backed up, then by
writing these parameters to the new C299MAIN board, matching with the existing printer
mechanism can be maintained and it is possible to omit a number of adjustment operations.
The backup operation basically consists of uploading the backup parameters (data) recorded
in flash memory in the existing C299MAIN board to a memory card, then writing the data
transferred to that memory card to the new C299MAIN board's flash memory.
If you have backed up the parameters correctly, by downloading these
parameters to the new C299MAIN board, part of the adjustments
using the self-diagnostic function become unnecessary. In this case,
perform the operation by the following procedure.
1. Back up the parameters from the previous C299MAIN board.
2. Replace the old C299MAIN board with a new one.
3. Download the parameters to the new C299MAIN board. (
4. Write the firmware.
5. Rewrite D/A corrected values.
6. Adjust the paper sensors.
