BJ30 Print Head Cleaning
The print head contains nozzles through which ink is propelled onto the paper. The print head nozzles must be
free from paper particles and dust in order to maintain a high level of print quality.
The printer has an automatic cleaning function that clears away paper particles and dust. The printer initiates
this automatic cleaning function when you turn it on after it has been off for a certain period of time.
You need to activate the print head cleaning procedure whenever your print quality is poor. There are two
types of print head cleaning:
• Quick cleaning to improve print quality problems. This procedure takes about 30 seconds.
• Extensive cleaning for severe print quality problems. This procedure takes about one minute, and uses
more ink than quick cleaning. Therefore, use this product only when the quick cleaning procedure does
not improve your print quality.
To start print head cleaning follow these steps:
1. Make sure the printer is turned on and on-line.
2. To start the quick cleaning procedure:
• Press and hold the CLEANING button for approximately one second, until the printer beeps.
3. To start the extensive cleaning procedure:
• Press and hold the CLEANING button for about six seconds. The printer beeps followed by a second
beep several seconds later.
While the print head is being cleaned, the ON LINE light will blink.
