14. 2ND IMAGE TRANSFER SECTION
B. 2nd image transfer control during image stabilization control
• In this machine, the 2nd image transfer roller does not have a retraction mechanism, so
that the transfer belt and 2nd image transfer roller are pressed up against each other at
all times.
• During image stabilization control, a toner image for adjustment purpose is formed on
the surface of the transfer belt. A negative voltage is therefore applied to the 2nd image
transfer roller during image stabilization control. The amount of toner sticking to the 2nd
image transfer roller is thereby reduced.
14.3.2
Control of toner application to 2nd image transfer roller
• In this machine, the 2nd image transfer roller does not have a retraction mechanism, so
that the transfer belt and 2nd image transfer roller are pressed up against each other at
all times.
• If a new 2nd image transfer roller that has replaced an old one is left to stand idle for a
long period of time, a substance contained in the new roller sticks to the surface of the
transfer belt, which could result in noise in the print image.
• To prevent the substance contained in the 2nd image transfer roller from sticking to the
transfer belt, Y toner is applied to the surface of a new 2nd image transfer roller at the
time of replacement. (The Y toner image that corresponds to two complete revolutions of
the image transfer roller is formed on the surface of the transfer belt and is then trans-
ferred onto the surface of the 2nd image transfer roller.)
• The Y toner that is less noticeable is used for the toner to be applied, in consideration of
back marking.
A. Execution timing
• The control is executed when the life counter of the 2nd image transfer roller in the ser-
vice mode is reset to zero.
NOTE
• The 2nd image transfer roller is not provided with any new article detection mech-
anism. If the 2nd image transfer roller is replaced with a new one, therefore, "New
Release" must be performed of the "Image Transfer Belt Unit" in life counter of the
Service Mode.
Performing "New Release" of the "Image Transfer Belt Unit" in life counter of the
service mode will also reset the life counter of the 2nd image transfer roller to
zero.
