This may be due to air bubbles inside your cartridge and we recommend that you stop printing immediately. Run the self-cleaning programme (according to the printer instructions) at least three times to clear any bubbles. The frequency and effect of cleaning may vary with the type of printer. If you do not stop printing, irrecoverable damage may be made to your printer.
