iR2270 / iR2870 / iR3570 / iR4570
At time of shipment from the factory, all machines are adjusted individually, and adjustment values are recorded in
their respective service labels.
If you have replaced the reader controller PCB or the DC controller PCB, or if you have initialized the RAM, the
adjustment values (for ADJUST and OPTION) will return to their default settings. If there has been any change in a
service mode item, be sure to update its setting indicated on the service label. As necessary, make use of the space
in the service label (as when recording an item not found on the label).
- Service Label for the Reader Controller PCB (behind the left cover [1] of the reader unit)
- Service Label [2] for the Main Controller PCB/DC controller PCB (behind the front cover unit of the printer unit)
