6.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the Status monitor
indicates Maintenance Request Error (This error is displayed as “unknown error” in the
STM3), take the following actions to clear the error.
o
Head Cleaning
When dot missing or banding phenomenon has occurred, printhead cleaning
operation is required by using the built-in head cleaning function. This function
can be executed only from the Printer driver utility and Service Adjustment
program because this printer dose not have any control panel.
Stylus COLOR 580 has 3 modes for manual cleaning and even during printing,
appropriate cleaning mode is automatically selected and executed according to
various conditions. When you select and execute manual cleaning in the Printer,
driver utility, the most appropriate cleaning mode is selected and therefore the
cleaning completion period varies depending on the mode. (Refer to “Ink
Sequence” on page 40.)
The following is the process to perform the head cleaning from the Printer driver
utility. As for the operation of the Adjustment program, refer to Chapter 5
Adjustment.
1. Make sure that the printer is in stand-by state by using the Status monitor 3.
If the printer is in standby mode, following figure is indicated on the monitor.

2. Select the Head Cleaning in the Printer driver utility and perform the Head
cleaning. After performing the head cleaning sequence, perform the print check. If
you repeat cleaning without print check, the weakest cleaning, CL1 will be
repeated.
