2. Symptom: 
In the case of halftone or solid printing, minor uneven contrasting density may be created at a 
26.8 mm pitch in the paper printing direction. 
 
3. General: 
Eccentricity of the DMX gear has an affect on printing surface at a constant pitch. The 
investigation of causes has revealed that minor uneven contrasting density is created at a 26.8 
mm pitch by two gears swinging at different intervals. The DMX gear engagement is adjusted 
properly by attaching the two DMX gears so that the D-cut sides of both DMX rollers align and 
their swing synchronizes. Consequently, minor uneven contrasting density will be reduced. 
For the production, the DMX gear has been attached as illustrated on the next page. Please 
take the measure on the next page for all DV units (BK/C/M/Y) when the abovementioned 
symptom occurs at a customer’s site. 
 
4. Measure:   
  1. Remove two DMX gears from the front side of the DV unit. 
2. Turn the D-cut sides of the right and left DMX rollers up. (Make sure that both rollers turn up). 
3. Attach the two DMX gears that have been removed in the step 1. 
(Note: Hold the right and left DMX rollers from the rear side of the DMX gears when 
attaching the gears. Confirm that the protruding portion of the DMX gear fits in the groove 
of the DMX roller.) 
 
 
 
 
 
 
5. Action:   
From mid January 2007 production
