Reason for

Modification

P arts catalog co rrection To meet standards ( ) To fa cilitate a s sembly Vender change Part standardization To improve reliability

Other The PCB - Op-port is no longer available to be supplied as a service part. Please order the Op-port unit instead of the PCB - Op-port.

< Reason>

1.W e can not assure qua lity w hen t r ansporti ng or replacing the PCB. *The PCB-op-port contains five PCBs and each PCB is connected by a flat cable. The flat cable may be damaged by transporting or replacing. *If the edges of the push switches for each key are pushed when transporting or replacing, the part may be broken.

2.The price of the PCB -OP-Port is almost the same a s the OP-Port unit.

The above problem is solved by the following modification.

Page 2/2

H081 2032R → H081 2032S H082 2400A → H082 2400B

However it is difficult to control the parts by suffix in the field, so we requested our designer to use new part numbers for the above parts. As the result, the above new part numbers are used. However,for the May production, H081 2032S and H082 2400B was used.

DETAILS OF MODIFICATION

Software change ( H5137108C → D, H5137109C → D )

1. Bit 5 of Service Switch 13 has been assigned. Service Switch 13, Bit 5 : Port used for G3 communication after switching to G3 mode from G4 mode.

0 : Follow Bit 3 of Service Switch 13.

1 : ISDN This bit is for machines which have PSTN connected to an internal telephone system and ISDN to an outside line directly. If ISDN-G4 is not connected for some reason, the machine automatically switches from G4 mode to G3 mode. In this case, G3 communication should not go through PSTN port because it goes through the internal telephone system which requires an access code for outside line.

2. Countermeasure for the following problem.

• Incorrect dialing caused by taking the handset off-hook while in the on-hook mode.

The amount of remaining memory below which ringing detection (and therefore substitute reception) is disabled if the printer is out of action (hex code, from 00 to FF, unit = kbytes) One page is about 24 kbytes. If this setting is kept at 0, the machine will detect ringing signals and go into receive mode even if there is no memory space left. This will result in communication failure.

080057 (Service Switch 17)

Image/Text detection threshold in halftone mode (Hex: 00 - 1F) 01: Almost all the data will be processed without halftone, even if the fax message contains photographs.
