6.1 Cleaning

This printer does not require regular cleaning. However, the following
areas can be cleaned of dirt or debris as needed:

Housing:
To remove dust and dirt, wipe the exterior of the printer with a soft,
clean cloth moistened with water. If the housing is stained with ink,
use a cloth moistened with a mild detergent to wipe it off.

Inside the printer:
To clean inside the printer, use a vacuum cleaner to remove any
dust or paper debris. To clean the paper feed roller, use a soft
brush to wipe off any dust, or use a soft cloth moistened with
FEDRON.

Never use chemical solvents, such as thinner, to
C A U T I O N
clean the printer. These chemicals can damage the
components of the printer.

Be careful not to scratch the surface of the paper feed
roller.

6.2 Corrective Maintenance

If you notice the print quality decreasing, or if all the LED indicators flash
simultaneously, the printer requires corrective maintenance. Take one
of the following steps:

6.2.1 Printhead Cleaning

If the print quality diminishes (for example, if you see missing dots or
white lines in the printout), you should perform the printhead cleaning
operation. You can perform this operation either from the adjustment
program or from the control panel of the printer itself. To clean the
printhead from the adjustment program, see
the printhead from the control panel, follow these steps:
1. Make sure the printer is in stand-by (the Power indicator is not
blinking). Also, check to make sure the ink cartridge indicators
are neither blinking nor on.
2. Hold down the cleaning button for at least 3 seconds.
The printer performs the cleaning sequence. During cleaning,
the Power indicator flashes. When the operation is complete, it
stops flashing and the carriage returns to the home position.

6.2.2 Maintenance Request

When all the LED indicators flash simultaneously, the printer is issuing a
maintenance request. A maintenance request occurs when the waste
ink pad is full and needs to be replaced. This is determined by an ink
counter that monitors the amount of ink expelled from the printhead
during cleaning. To remove and replace the waste ink pad, see
4.2.4.2. After replacing the waste ink pad, you must reset the ink
counter in order to clear the maintenance request. To reset the ink
counter from the control panel, see
adjustment program, see Section
