Nouvelle mise à niveau - Unité de fusion HP M552

CET has carried out a series of technical upgrades for the HP M552 fuser to solve the phenomenon of blackening and drying of grease after continuous printing, and greatly improve the service life of the fuser.

1. Optimiser le design

Améliorations de la conception de la thermistance

CET optimized the thermistor design, and adjusted the thickness of the polyimide tape wrapping the crystal from 0.04mm to 0.02mm, so as to cool down and protect the grease.


Chauffage de mise à niveau

CET improves the lubricity of the coating on the working surface of the heating plate by 200%, the surface roughness is


2. Détection de mise à niveau - test de haute et basse température

CET uses 70g/80g/100g/120g paper respectively to conduct continuous printing tests for OEM and CET fusers. Under different humidity and temperature environments, the CET fuser performs well, and the fixation firmness is close to or even surpasses that of OEM.
