Modified Points or Symptom Corrected
just after a network printing time-out error has occurred on the previous job.
SP1-155-013 can be set to a value of "2" (this setting can now be used) to switch
from half-wave control to phase control.
Note: This is effective in reducing flickering of the fluorescent lamp when printing.
The image may be printed incorrectly on one page if the paper runs out during a
full-color duplex job.
Color misalignment may occur if the user performs Auto Color Registration.
A reduction in printing speed (CPM), hot offset, other fusing issue, or a fusing SC
may occur if SC620 is triggered 50 or more times.
The paper size display does not appear for a tray after it is loaded with paper, and it
is not possible to print using this tray.
SC552-02 occurs if SP1-135-001 is changed to "1" and the fusing lamp is not at
100% output.
The developer clutch moves and makes noise during machine shutdown.
Firmware modified so that even if a PCDU from one machine is removed,
temporarily installed on another, and then returned to the original machine, the
machine remembers the counter and replacement date information for the unit.
SP1-155-013 was changed (control is different when set to "1 ") to minimize
flickering of the fluorescent lamp.
SP1-155-013: Select the fusing heater control
0: Normal (default)
1: Use other heater control table
Toner control was modified to minimize fluctuations in toner concentration, in order
to minimize toner scattering inside the machine.
Jam 67 occurs if a continuos print or copy job is performed with A3 SEF (over 3
sheets) and A4 LEF mixed together.
SC549-04 could occur, if the fusing shield gets stuck while it attempts to reach home
position.
JAM24 occurs, if the leading edge of the paper contacts with the paper exit pawl.
The SP values listed below were changed for the following reasons:
-
To improve the print speed when using SRA3 paper
-
To optimize the TEC value
Note: The values vary depending on the model and destination.
SP1-102-024, 025
SP1-102-031, 032
SP1-107-001, 005
SP1-117-134, 144
SP1-121-010～020
SP1-127-004
SP1-127-006
SC370 could occur during Process Control.
