Feed roller traction loss
Glazed rubber tires lose mechanical friction against paper reams, causing continuous misfeed warnings at the entry tray. Wipe roller surfaces with concentrated isopropyl alcohol to restore traction.
Fuser assembly wrap
Media binds around the heated pressure sleeve when thermal switches fail or toner adhesion collapses. Never use metallic probes on delicate Teflon sleeves; allow cooling before clearing jams.
Thermal and electrical isolation
Disconnect main power and wait thirty seconds for internal power capacitors to discharge completely. Fuser assemblies maintain hazardous surface temperatures above two hundred degrees Celsius following operational shutdown.

Clean rubber pick-up tires, inspect cassette separation pads, and extract loose toner particles from the staging feed bay using an antistatic vacuum.
Replace worn feed tires, calibrate optical registration sensors, and inspect lateral carriage drive belts for slack or tooth wear along the chassis axis.
Overhaul heated fuser rollers, refresh transfer belt assemblies, and apply synthetic grease to high-torque gear trains inside the central transmission casing.
