Heil. Why is green light flashing 4 times?

Hi there SWCopiers,

Four flashes indicates 'Ink tanks installed incorrectly' or 'Printer needs repair'.

Click here for iP90 ink tank install procedure.

Click here for reset procedure.

Click here for instruction on contacting Canon Support. They have been very helpful. If it turns out that one of your ink tanks is faulty, they have replaced them at no cost in the past.

Hope this helps.

Yes, inspect the air intake, exhaust pipe, filter and condensate piping for blockage or moisture. Also check for a hole in the hose that goes from the small exhaust blower to the pressure switch or a bad connection on the switch or control board. You may be able to temporalily jump the switch for diagnostic purposes only.

if it has a pilot, you can follow the pilot tube from the gas valve back to the burner assembly and find it. It may not have one and if this is the case, the air flow switch is supposed to close when the inducer fan comes on . If the flue is clogged, condensation in the bottom of inducer fan(would hear cracking). then after the draft safety switch is closed,the gas vavle will get 24 volts and allow the gas valve to open
