1.1 Overview

This section covers the features and specifications of the plain paper facsimile transceiver "Panasonic UF-885/895". This fax
machine can transmit and rec eive on the Publ ic Switched Telephone Network (PSTN) in modes conf orming to ITU-T / CCITT Group
3 recommendations.

1.2 General Features and Functions

1. Laser Printing
Clear picture quality is obtained by employing a Laser p rinting method on plain paper. The machine can print onto A4, Letter
or Legal size paper.

2. Quick Scan
Quick Scan speeds the fax proce ss by scan ning a nd stori ng doc umen ts i nto me mory a t a rate of appro xi matel y 1 se cond* p er
page. This means that you no longer have to wait around until a transmission is completed before retrieving your originals.
(* UF-885 : 2.8 seconds, based on ITU-T Image No.1 Test Chart at Standard Resolution. The Scanning speed applies only
to the feeding process from the leading to the lagging edge of a single page test chart. The time it takes to store the
document into memory is not applied for this definition)

3. Easy Maintenance
This laser printing mechanism only requires changing the toner cartridge, housing the drum, developer and toner.
Unlike other machines with removable EPROM (Erasable Programmable ROM), this machine is equipped with an F-ROM
(Flash ROM). F-ROM offers the flexibility of quick and easy firmware updates, creation of a master firmware card, backup
and restore of firmware and machine parameters.

images by smoothing the curved edges of the character.

6. B4 size Scanning
B4 size is the maximum document width that can be scanned and transmitted.

7. Automatic Document Feeder
An Automatic Document Feeder feeds originals from the document tray automatically, starting with the bottom page.
Capacity: 50 documents of average thickness and of the same size.

8. Speedy Transmission
The use of JBIG Coding with ECM achieves faster transmissions. Short Protocol reduces hand-shake time by shortening
Phase B and D.

9. Error Correction Mode (ECM)
An Error Correction M ode, which confor ms to ITU-T/CCITT Recomm endatio ns, all ows erro r-free d ata trans mission . ECM with
MMR or JBIG Coding also conforms to ITU-T/CCITT Recommendations.

10. Automatic Dialing Function
Up to 200 stations can be easily dialed by One-Touch Dialing or Abbreviated Dialing Function. Any other stations can be
dialed directly from the keypad by entering the full telephone number (UF-895: up to 70 stations, UF-885: up to 32 stations).

11. Memory Transmission
The contents of a document can be stored into the document memory first, then transmitted from memory. Operator
attendance until transmission ends is not necessary.

12. Multi-station T rans m iss io n
Using the document memory, the document can be transmitted to multiple destinations.

5

General Description

13. Multi-file Transmission
It is possible to store multiple documents, each of which could be transmitted to different destinati ons, into the document
memory. Then the unit will transmit them sequentially (max. number of files: 30 files [UF-885], 70 files [UF-895]).

14. Deferred Communication
The built-in 24-hour timers allow the operator to set deferred transmissions or deferred polling. Using the document memory,
documents can also be transmitted to multiple stations.

15. Substitute Reception
The contents of a documen t will be receiv ed into the docum ent memory if the re cording p aper or toner runs out, or a recording
paper jam occurs d uring recep tion. The s tored docu ments c an be printe d after repl acing the recording p aper or toner cartri dge
or correcting a paper jam.

16. Multiple Operation
Multiple Access operations can store documents and their destina tion s even during reception or mem ory tran sm is si on. I t can
also receive during document storage.

17. Halftone (Photo)
For transmission or copying, this function ensures high quality reproduction of gray-shaded or photographic documents. This
machine uses 64 levels of error diffusion to create halftones with Quality mode.

18. Copy Function
The Copy function al lows the mach in e to be used a s a co pier. Using the document memory, up to 99 copies can be made of a
single original.

19. 100 Transaction Journal
The 100 Transaction Journal provides transaction information - number of pages transmitted or received, start date and time,
communication res ult s , identification, etc. It is automatically prin ted af ter ev ery 10 0 transactions, or i t c an be printed manually
at anytime.

20. Latest Individual Transmission Journal
The latest Individual Transmission Journal provides information on the last transmission - number of pages transmitted, start
date and time, communication results, identification, etc. It can be printed manually at anytime after communications.

21. Communication Journal
A communication journal is a result report of a communication which can be printed automatically after communication is
completed. Printout conditions can be selected for each communication to 1) not print, 2) always print, or 3) print when
communication has failed.

22. Multi-purpose LCD Display
The 20 x 2 Alphanumeric LCD displ ay shows the operation mo de, date and tim e, remote ID numbe r , and p ages tran smitted or
received. In case of an error, the LCD display shows an information code and error message indicating the exact cause of
trouble.

23. Verification Stamp
The Verification Stamp is automatically stamped on the original document when the document is transmitted or stored in
memory successfully. The "X" mark appears at the bottom of each page.

24. Password Transmission
A password transmitted from the other party is checked to prevent the transmission of documents to an unauthorized station.

25. Password Reception
A password transmitted from the other party is checked to prevent the reception of documents by an unauthorized station.
The reception of junk mail, etc., is preventable.

26. Access Code
The Access Code can be registered into the machine to prevent operation by an unauthorized user.

27. S elective Reception
To prevent unwanted faxes from being received, the machine compares the ID Number of the transmitting machine with the
telephone number stored in the built-in automatic telephone dialer.

28. Receive to Memory
Users can set the unit to store incoming documents into its available memory. Later, using a 4-digit password, stored
documents can be pri nte d w hen the u se r is pre se nt. This function helps ens ure that imp ort ant documents are no t read or lo st
while they are sitting unattended in the fax tray.

29. Relay Transmission Request
By setting the machine as an initial sending station, the unit is capable of setting up a relay request to a central hub machine
with a network password. Documents can then be automatically transmitted to the end receiving stations. This model is
designed to operate as an initial sending station.

30. Confidential Transmission and Polling
The documents can be transmitted to a predetermined destination with a 4-digit confidential code utilizing the Confidential
Mailbox function. Stored messages in the Confidential Mailbox can be polled by the receiver at the destination terminal.

31. Confidential Mailbox (Proprietary)
When the received message is stored into the memory with a 4-digit confidential code, the message can be printed on
recording paper or polled by a remote station. A maximum of 20 mailboxes* can be used. A remote confirmation report such
as Confidential Memory Report and/or Confidential XMT Report is not transmitted to the source station and/or the remote
station after Confidential Mailbox reception or polling transmission. (*UF-885: 10 mailboxes)

32. Remote Diagnostic Function
The remote Diagnostic Function can be used to diagnose the unit remotely over the PSTN or equivalent. A new host system
is required for high speed remote diagnostics to be available.

33. Check and Call Function
