not need electricity. Refer to GP 14. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION

the ink reservoir located at the back of the unit if opened with too much force. Cross-colour ink
contamination could also occur.
CAUTION
Do not touch the exposed face of the printheads. Surface contamination or minor damage can
easily make the printhead unusable.

• Faded lines in the process direction with indistinct edges, Figure 4. The defect is notice-
able in all colours but may be more apparent in some, Figure 5. If observed, go to Unifor-
