Chapter 6 Maintenance
6.1 OVERVIEW
This section describes the points and the procedures for maintaining the printer in its optimum condition.
6.1.1 Cleaning
This printer has no mechanical components requiring regular cleaning. Therefore, the points described below are suggested to be checked for any dirt and make an appropriate cleaning if necessary.
CAUTION
Never use the chemical solvents, such as thinner, to clean the printer. These chemicals can damage the components of the printer. Be careful not to damage the components when you attempt to clean the inside of the printer. Do not scratch surface of "ROLLER, ASSEMBLY, PF". (Use soft brush to wipe off any dusts, or use soft cloth moistened with alcohol)
Use clean soft cloth moistened with water and wipe off any dirt. If the housing stained with an ink, use a cloth moistened with a neutral detergent to wipe it off. Inside the printer: Use a vacuum cleaner to remove any paper dust. Housing:
6.1.2 Service Maintenance
If the print irregularity (missing dot, white line, etc.) has occur or the printer indicates "MAINTENANCE ERROR", perform the following operation to clear the error.
Head Cleaning 1. The printer has a built-in head cleaning function and is executable from the control panel. 2. Confirm that the printer is in stand-by state (the POWER indicator is not blinking), and hold down the cleaning button on the control panel for more than 3sec. 3. The printer perform the built-in cleaning sequence. (during cleaning operation, the POWER indicator is blinking)
Maintenance Error Clear Since the printer consumes the ink, not only for printing but also for another operation like cleaning, certain amount of ink are wasted. Therefore, the printer counts the amount of waste ink and they are collected at the waste ink pad, and once the amount of waste ink reaches the predefined limit, the printer indicates "MAINTENANCE ERROR" and the waste ink pad should be replaced as follows: 1. Replace the waste ink pad to new one. 2. After re-assemble the printer, turn the printer on while hold down the following buttons on the control panel: "LOAD/EJECT" button "CLEANING" button 3. Press "LOAD/EJECT" button again while "PAPER END" indicator is blinking. This clears the maintenance error condition and the waste ink counter value stored in EEPROM of the main board.
