1 General Description
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 receive on the Public Switched Telephone Network (PSTN) in modes conforming to ITU-T / CCITT Group
3 recommendations.

General Features and Functions
1. Laser Printing
Clear picture quality is obtained by employing a Laser printing method on plain paper. The machine can print onto A4, Letter
or Legal size paper.
or Legal size paper.
2. Quick Scan
Quick Scan speeds the fax process by scanning and storing documents into memory at a rate of approximately 1 second* per
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.

4. Batch Transmission
The UF-885/895 permits accumulation of different documents for the same destination(s) to be transmitted in a single phone
call.

5. Panasonic Super Smoothing
The machine incorporates a new sophisticated image processing technology to enhance print quality of ordinary received fax
images by smoothing the curved edges of the character.
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 Mode, which conforms to ITU-T/CCITT Recommendations, allows error-free data transmission. 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 Transmission
Using the document memory, the document can be transmitted to multiple destinations.
