Spec Change

1) In the scale setting screen, the interval between the icon for [scale down] / [scale up] and the

icon for [25%] / [200%] was narrow and it was difficult for each user to press it, so the interval
between two icons were changed.

2) In Italian version, the expression of Saddle Stitch was changed. [CUCITURA SELLA] 

[PINZATURA SELLA][FASCIC. RIVISTA & CUCIT.SELLA] 

 [FASCIC. RIVISTA &

Corrected Problems

1) [Media Type] is selected for all cassettes, so the machine does not find an appropriate cassette if

the print job is sent from the Controller, and then the message is indicated on LCD.  This message
was changed as follows:
Before Change: [Please insert the cassette with correct size: <paper size>]

   

After Change: [Please place the paper to the manual feeder: <paper size>]

In the area <paper size> above, the actual paper size like [A4] is indicated.

2) After rebooted, the machine is automatically placed online.
3) The limits were placed on the characters used for the scanned file name.
4) The wording [Password Change] was changed to [Password Setting].
5) The wording [Reset] was changed to [Reboot].
6) If [Saddle] and [Cover Page (Inserter)] are selected, the paper in the inserter is reversed.
7) The range of time out setting for the parallel port was changed.
8) In the serial copying operation immediately after 05-code, the developer was not correctly fused.

This was corrected.

9) The problem of the web motor signal channel (CD5) was not correctly detected.

This was corrected.

three hundred times when IH is on/off, the fuser unit is rotated for 10 seconds.

11) To prevent the guide jam from occurring when the paper for Tandem LCF is transferred, the

check control system was added.

12)*The input check control system was added for the middle transfer sensor.
13) The control system was changed so that the leading edge of the image is not shifted when the

Note) - In [08-219], it is possible to turn the LCD backlight off in power save mode in order to

efficiently save the energy consumption on 55/65 cpm model.

Originally, the LCD backlight was turned off on 55/65 cpm model but turned on for 81
cpm model, however, from now on the control system was changed so that this was
able to be set in this code. For the factory setting, [OFF] is set for the LCD backlight of
the model for local market in Japan in power save mode. (Please note that this is
disabled on the models for overseas market although it is possible to operate this code.)
 - In case that [1] is set for the code [08-502], please be sure to use the Scanner ROM

(Ver.07 or later) for combination.
