Which statement is true about the use of fusing oil in HP Color LaserJets?

Question

Options

• AFusing oil is used in the HP Color LaserJets to improve the print quality on glossy print media
• BThe HP Color LaserJet toner particles have a wax core, so they do not need any oil system
• COil systems are necessary for HP Mono LaserJets only
• DThe HP Color LaserJets toner particles are mixed with waxed paricles in the toner cartridge, so

• A
  5% (3)
• B
  89% (57)
• C
  5% (3)
• D
  2% (1)

Explanation

HP Color LaserJet toner is engineered with a wax core embedded inside each toner particle, which melts during the fusing process to bond the toner to the paper - eliminating any need for an external oil system. Option A is wrong because fusing oil is not used in HP Color LaserJets at all, regardless of media type; the wax core handles what oil would otherwise do. Option C is wrong because it misattributes oil systems to Mono LaserJets exclusively - this is a false distinction; the wax-core design is the key differentiator for Color LaserJets specifically. Option D is incomplete as written, but the wax is not a separate particle mixed in - it is the core of each individual toner particle, which is an important design detail.

Memory tip: Think "color toner = wax inside, no oil outside" - the wax core is self-contained, making an external oil delivery system unnecessary.
