Canon i550 yelow light on: "operator error" . Have tried to resume and delete printing tasks and restarted printer


Had the same problem with my I550. Was going to buy a new printer (I4000) since I could get one for about $30 more than the price of a new print head. I like canon printers with the individual ink tanks and have had no problems with the I550 for about three years.

Decided to try moving the paper thickness lever back an forth a number of times since some of the error messages indicated it could not determine the setting of the paper thickness lever. I don't know how the printer determines this switch setting but I thought if some contacts are slightly oxidized that movement might break up some of the oxidation. After operating the lever about a dozen times the printer started working. Hope this will help.
