5.3.5 Head Cleaning Operation

Unlike many previous models, the Stylus Scan does not have a dummy cleaning sequence called CL3, which was performed to prevent ink from being unnecessarily consumed when cleaning was repeated without any printout. However, Stylus Scan is alternatively equipped with the strongest cleaning sequence CL2 contained in this adjustment program. With this sequence, you can forcibly solve the clogged-nozzle problems that were caused by viscous ink.

C A U If you cannot recover the clogged nozzles even after performing the CL2 operation, enter the Initial ink charge sequence by referring to “Initial Ink Charge Operation” on page 122.

1.Enter the Production menu as described in “Using the Service- Adjustment Program” on page 116.

2.On the Production menu (Figure 5-6),select Cleaning. Then click OK in the dialog box that appears.

3.The printer enters the CL2 sequence.

The CL2 cleaning operation takes 60 seconds to complete.
