Operator panel removal (all models)
Warning: Do not replace the operator panel and controller card at the same time. Each card contains the
printer settings. When either of these cards is new, it obtains some of the settings from the other
card. Settings are lost when both are new and replaced at the same time.
1. Remove the left cover. See “Left cover removal” on page 4-5.
2. Disconnect the cable from the controller card at J16.
3. Remove the two screws (A).
4. Remove the card assembly.
Warning: Do not change the operator panel at the same time as you change a controller card. Special settings
will be lost.
