Symptom corrected:

Under the following conditions, the final page or the pages near the end of the 1st copy are stapled into the 2nd copy.

1.      The customer sets "Staple" on the printer driver and makes two or more copies.

2.      Paper end occurs on the final page or near the end of the 1st copy.

Other Changes:

1.        When the machine is in the paper end condition during limitless feed mode, the machine does not start the next job before the previous job is completed.

2.        Improve the reliability of continuous action among printing jobs while multiple continuous printing with the staple function is selected.

Symptom corrected:

SC552/SC555 occurs due to fusing heater damage (meltdown).

Note: This issue only occurs on the 220V model.

Other changes:

The amount of toner consumed by the machine in Refresh Mode was decreased.

Symptoms corrected:

1.      The firmware update process for a machine peripheral is interrupted, and the machine does not retry the update even after being rebooted.

2.      The PM counter value for the AIT unit is not updated unless the machine power is turned off before the unit is replaced.

3.      The SP numbers for the PCU counter/rotation for Magenta and Cyan are incorrect.

4.      Fan motors do not stop when the waste toner bottle is full.

Note: The related SP setting was changed to "1", so that the motors shut off in one second.

Other changes:

5.      The timing conditions for performing MUSIC were changed (MUSIC will no longer be triggered by the elapsed time since the previous performance).

Note: This is to realize the following benefits:

-          Waiting time is minimized

-          Toner consumption is reduced

-          The accuracy of the synchronization of MUSIC for the PCU and development unit is increased

6.      When thin paper is selected with 1200dpi mode, the fusing temperature for "Plain 1" (SP1105-128 to 131) is used, which can minimize paper curl.

7.      (Minor change applied for the Japanese domestic model).
