[Misc] Canon Imagerunner 5050

[Tfly]

Just replaced the lower fuser roller again after only 105,000 impressions.
Service tech gyu suggested that premature failure was due to running carbonless paper.
Anyone else have this problem?
Could there be another reason for the failure?

--------

105,000 impressions on carbonless (CCP) paper

chronic exposure to carbonless copy paper can be hazardous

Re: Canon Imagerunner 5050

These machines eat pressure roll bearings and the shaft ends disintegrate. Why did you change pressure roll? Creasing? Always replace the bearings with the roller(it actually comes with the bearings...depends what part number you use)

What causes problems are the dyes and chemicals used on those NCR/carbonless papers. The first dye used commercially in this application was crystal violet lactone, which is widely used today. Other dyes and supporting chemicals used are PTSMH (p-toluene sulfinate of Michler's hydrol), TMA (trimellitic anhydride), phenol-formaldehyde resins, azo dyes, DIPN (diisopropyl naphthalenes), formaldehyde isocyanates, hydrocarbon-based solvents, polycyclic aromatic hydrocarbons, polyoxypropylene diamine, epoxy resins, aliphatic isocyanates, Bisphenol A, diethylene triamine, and others. The dyes in carbonless copy papers may cause contact dermatitis in sensitive persons.

Hard on lower fuser rollers and bad for customers health due to compounds released when heated. Canon actually has some carboness paper they recommend which may run cleaner and cause less problems. Here's a link: Canon Introduces Three New Specialty Media to Aftermarket Portfolio | Business Wire
