Abstract
The fuser roller in a fixing unit of a (duplex) electrographic copying or printing apparatus is provided with an oil application system having an oil sump, two metallic rollers for delivery of fusing oil to a applicator roller contacting the fuser roller. The system is characterized by an oil transfer coefficient C which is not higher than 0.5 in order to avoid visible stepwise variation of fuser oil offset on the final copy. The system can further be provided with an oil compensation roller for further improvement of oil distribution on the copy and can be equipped with a cleaning system to remove picked-up impurities.
