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.
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.
Using the Service-Adjustment Program
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.
The CL2 cleaning operation takes 60 seconds to complete.
