https://community.usa.canon.com/t5/General-Discussion/Canon-K940-Copier/m-p/284156#M25541 <P>Old K940 analog copier has been a workhorse. Just replaced the cartridge with Canon original.. No other adjustments. Exposure is way off. On lightest auto setting white backgrounds still are gray. At usual mid exposure auto setting, backgrounds are very dark. Manual adjustments are no better. Is there a senor that can be replaced? Hate to throw it away.</P> Thu, 17 Oct 2019 16:50:05 GMT Selrach927 2019-10-17T16:50:05Z https://community.usa.canon.com/t5/General-Discussion/Canon-K940-Copier/m-p/284156#M25541 <P>Old K940 analog copier has been a workhorse.
