Items to be Checked
OKI Data Infotech Corporation CONFIDENTIAL
Check that the ambient temperature is within the operating
temperature range.
(1) Check that the print head cable jacket is not damaged.
If damaged, replace it.
(2) If not damaged, reconnect it and restart the printer.
(3) If the problem persists, replace the cable of the faulty
print head with one of a print head operating normally.
If the error number changes, the faulty part is the print
head cable so replace it.
(4) Connect the print head cable to another print head. If
the error number changes for the newly connected
print head, check the other items to be checked below.
* The print head cable for the seventh print head is used
only for 7-color printers.
Check that the width of the V-shaped folded part on the FFC
is proper. If not, adjust it. For the adjustment procedure, see
6.8.4 PCB-ASSY-HCB1M.
Check the following to ensure that the FFC is not damaged.
- FFC's terminal is detached from its base.
- FFC's edges have not been abraded by friction.
If the FFC is damaged, replace it.
