Faint printing issue / Drum pin hole issue (New Firmware) PAGE 3
In case of a color stability issue:
Before the machine wakes up from sleep mode the developer rotates for approx. 20sec. This is related to the toner
deterioration and color stability. We have reduced this time to approx. 5Sec.
The firmware includes two new engine version

Engine FW (250ci 300ci) 2JZ_1000.C05.001 (NEW)←
Depending on the coverage, mode 2 can be used as well.
The customized engine firmware includes these automatic settings.

TROUBLESHOOTING GUIDE
Preventing wrapped paper in transfer (Measure against J31/J4X) PAGE 4
Phenomenon :
Paper may be wrapped around the primary transfer belt after primary transfer process, and then J31 (Misfeed round the transfer belt)
or J4X (Misfeed in fuser section: X is the paper feeding source No.) may be displayed depending on the paper properties (weak stiffness/upward curl/thinness).
Therefore, the following are changed.
Contents of change:
To prevent J31/J4X and the paper wrapping around the primary transfer belt, the paper separation films (No.8, 9) are affixed in between the guide pulleys at
the machine left side of the primary transfer belt.
The paper separation film (2 each sheets of No.8, 9 or 3 sheets of No.9) and the instruction leaflet are bundled in the primary transfer belt unit for service
(No.1-7) and MK kit A.
State after affixing the paper separation film (No.8, 9)
Papr separation film: below is the state that the film is affixed in 0mm of the
vertical alignment. (Please refer to the page 3, 4 for the alignment.)

Field Measure:
When the phenomena described in the previous page occur, please affix the paper separation film (No.8, 9) after cleaning the
(When affixing the film, please remove the fuser unit and slightly pull the primary transfer belt unit leftward.)
And, when replacing the primary transfer belt unit or MK kit A, please clean the affixing position with alcohol and affix the
that is bundled.
[Note] Please check if the paper separation film does not contact the primary transfer belt after affixing the film.

When the paper is wrapping around the upper side of the primary transfer belt, if the end user does not notice the paper and only opens and
closes the cover, the paper is not removed because only the paper jam indication disappear by opening/closing the cover. If continuing drive
in that state, the paper may enter into the inner part of the primary transfer belt and then the cleaning failure at the primary transfer belt
may occur.

PAGE 6
Phenomenon:
In case that a paper jam occurs at the fuser section and the job separator (*), the next fed paper might be pleated when it hits the jammed paper or a piece of torn paper
remaining after clearing the paper jam. Then, the trailing edge of this paper may wrap around the fuser roller.
If the phenomenon described above arises, it is difficult to clear the paper jam and C6000 (Service call detecting fuser problems) may appear. Therefore, the following
changes were made.
(*: J4x/J5x is detected.)
