Model: TASKalfa552ci

Content of changes

1 PanelPlus and FMU are now supported.

2 Error code CF245 may occur.

3 The Operation panel may become locked (No response from the hardware key and touch panel)

4 After errror code C0630 occurs, the error code may not appear in the Event log.

5 The memory LED may continuously blink, after printing les from the optional NIC from SEH.

6 The Command Center contents may be over-written.

7 The PJL status may not be completely returned, when sending print data by the KWOM (OM macro4 spool

10 The machine may become locked, when printing PDF les directly from USB memory.

11 Data may not be converted and error code CF2A4 may occur, when the received i-fax contains

unconvertible data.

12 Phenomenon

Failure to send the Fax may occur.

Cause

The Fax memory may fail to initialize, due to the internal control version le error at start-up.

Solution

To initialize the Fax memory properly, the version le is rebuilt if it contains errors.

13 A communication error may occur, when trying to read SNMP OID 1.3.6.1.2.1.43.7.1.1.2.1.7

14 The printer output tray may not be selected, when setting this at the System menu as follows.

System Menu > Common settings>Function Default > Collate/Offset

Collate: On,
Offset: Offset Each Set (Offset Each Page)

15 The page order may be incorrect, when outputting booklet copy jobs.

16 An incorrect folder may be opened, when attempting to open another folder at the Document Box.

17 Umlaut characters may appear garbled on the print-out, or an incorrect font may appear.

18 Barcodes in PCL prescribe commands, may appear as compressed images aligned to the left on the

print-out.

19 Error code CF248 may occur.

20 Only 1 set of the print-out may contain the Watermark, when the data contains the SCG/RPG Prescribe

command.

21 The characters may appear garbled on the print-out.

25 Character spacing may be incorrect, when printing Macro data.

26 Parts of the font may appear rotated in a 90 degree angle, on the print-out.

27 The “0” character may be skipped, when printing PDF data.

28 Phenomenon

Colour images may be partly skipped on the print-out.

The colour image may be
skipped toward the main scan

Main scan direction

direction, as a curved shape.

Cause

The one-way clutch is partly caught by the Mylar lm, and stops where the laser beam path is interrupted by the

cleaning blade.

Main scan direction

Single colours may be skipped .

Solution

Therefore the following changes has been made:

1. The feed motor will rotated in reverse at half speed. Then it is rotated at full speed, after nishing the LSU

cleaning process, so that the cleaning blade return to the home position.

2. To implement the above mentioned changed, the following function has been added to

Maintenance mode U474 (Checking LSU cleaning operation): Reverse rotation: 0=OFF (Default) / 1=ON

Notes

Please note that the warm-up timing will be delayed by 4 to 6 seconds, after turning ON the Reverse rotation.
The value will be set to 0 (Default) after upgrading the Firmware.

29 To improve the print speed, the threshold for shifting the paper interval control mode has been changed at

Mode5 of Maintenance mode U325. (Shifted to Mode5 depending on the drive time at Mode1)

30 Phenomenon

A faint black image may appear on the print-out.

Solution

The Firmware has been changed as follows:

The target value, for the toner thick layer calibration (Black) at maintenance mode U464, has been made

variable.

Procedure

1. Execute Developer refresh and manual calibration.

2. Increase the black target value at maintenance mode U464, if the phenomenon occurs, after performing
Developer refresh and manual calibration. (Thick Calib Add Bias (K)) Please note the image may appear

faint or background may occur after increasing the above mentioned value.

3. Perform the Manual calibration (This xes the changed value).

4. Check the image level. Change the value depending on the level.
The default value changes from +10 to 0, after this change.
