1. Model Name: MX-M850/M950/M1100 
 
2. Symptom:
 
If contact resistance between the MG roller shaft of the developing unit and the 
sintered bearing of the sleeve varies, the developing bias voltage also varies. 
Consequently, faint irregular print image may be printed on paper at irregular pitch in 
the printing direction when printing images with halftone. 
 
3. Description:
 
In order to even out the variation of the developing bias voltage owing to the variable 
contact resistance between the shaft and sintered bearing, an MG spring has been 
added to the MG roller shaft. As a result, constant contact resistance between the 
shaft and sintered bearing has been enabled and the irregular print image at an 
irregular pitch has been improved.
