HIGH QUALITY, HIGH SPEED

SUPERIOR IMAGE QUALITY
Both the PC-D320 and PC-D340 guarantee excellent image quality for all your work whether fine text, detailed diagrams or even photos. 256 greyscale reproduction provides perfect halftones, and auto exposure ensures you always get the best results. Apart from consistently high copy quality, there's an economical toner-saving mode to cut costs.
FLEXIBLE DIGITAL FUNCTIONS

PERFECT LASER PRINTING

Both copiers feature a USB port, allowing you to transform your unit into a productive 14 pages per minute laser printer. With a 1200dpi (enhanced) print resolution you can take advantage of both high quality and high speed

SPEED ALWAYS AT 14 CPM

Speed is a constant 14 copies per minute for both models - even when you are using the 50-sheet Automatic Document Feeder on the PC-D340. There is no slowdown in speed as documents are fed to match the printing speed. There's virtually no warm-up time and also a fast first copy out time - in only 11.2 seconds. So you get through all your work faster.
printing. Thus giving you both superior printing and copying, all in one compact and costefficient machine.
EXTENSIVE DIGITAL EFFICIENCY
Thanks to the flexible digital functions of the PC-D320 and PC-D340, you can easily increase efficiency. Use the convenient 2-on-1 copying function to copy two originals on a single sheet of paper, thus saving on paper and filing space. A 'scan once print many' feature prints multiple

All-in-One cartridge

Convenient 2-on-1 copying copies from memory. And save time with electronic sorting, as multiple sets are printed out with pages collated. No mechanical sorter is needed.

Figure 1-4 USB Data Transfer
Encoding/Decoding the Data In USB, data transfer lines are ultimately encoded with NRZI (Non Return to Zero Invert) method. When the original data bit is 0, sent data bits are inverted; when the original data bit is 1, the value is retained. However, if the level of the transferred data remain unchanged for a certain period of time, the receiving side may not be able to synchronize with the data sample position, which will result in data bits being out of phase. This is prevented by a method called bit stuffing; when data bit 1 is repeated 6 times, one 0 bit is added to the original data before encoded with NRZI.

1. Paper Guide for PC-D340/FAX-L400 only This guide is used to hold the document in horizontal direction to prevent it from moving askew. 2. Pick-up Roller for PC-D340/FAX-L400 only This roller is used to pick-up a document and feed it to the separation roller. 3. Separation Roller for PC-D340/FAX-L400 only This roller uses differences in the coefficients of function of the separation guide, document and separation roller to separate each of the sheets in a multiple-page document. 4. Document Feed Roller for PC-D340/FAX-L400 only This roller feeds documents to the contact sensor after they are separated by the separation roller. 5. Contact Sensor The contact sensor scans the image information from the document, converts it to serial data, and transmits it to the SCNT board as an electrical signal. The contact sensor has a scanning resolution of 600 dpi. 6. Document Eject Roller for PC-D340/FAX-L400 only This roller ejects documents fed from the document feed roller. 7. Document Feed Motor for PC-D340/FAX-L400 only This motor drives all the rollers in the scanner section. 8. CS Drive Motor This motor drives the contact sensor.

3.2.1 Pick-up delay jam

This machine performs retry control to redress the pick-up delay jam caused by pick-up error. In this control, a pick-up operation is conducted a maximum of twice. If the page top sensor cannot detect the leading edge of the paper within 1.4 seconds after the pick-up solenoid is turned ON in the first pick-up operation, the CPU tries another pick-up operation, the CPU determines a pick-up delay jam.
3.2.2 Pick-up stationary jam
If the page top sensor cannot detect the trailing edge of the paper within 4.6 seconds after detecting the leading edge, the CPU determines a pick-up stationary jam.

3.2.3 Delivery delay jam

If the leading edge of the paper cannot reach the paper eject sensor within 2.1 seconds after the page top sensor detects the edge, the CPU determines a delivery delay jam.

3.2.4 Wrapping jam

The CPU determines a wrapping jam under both the following two conditions: 10 seconds passed after the paper eject sensor detected the leading edge of the paper The paper eject sensor cannot detect the trailing edge within 1.5 seconds after the page top sensor detected the leading edge. In case of judging a wrapping jam, the CPU notifies the jam as a delivery stationary jam.
3.2.5 Delivery stationary jam
If the paper eject sensor cannot detect the leading edge of the paper within 2.2 seconds after the page top sensor detected the trailing edge, the CPU determines a delivery stationary jam.

3.2.6 Residual paper jam

During the initial rotation period, if the page top sensor or paper eject sensor detects the paper, the CPU determines a residual jam.

4. PRINTER SECTION

The LASER beam printer engine comprises the following sections.

Laser/Scanner section

Toner cartridge

Fixing section

Toner transfer section
Figure 2-6 Printer section
4.1 Laser/Scanner Section
This section comprises a Laser unit, cylindrical lens, 4-faced polygon mirror, scanner motor, imaging lens, reflection mirror and BD sensor. The Laser is driven in accordance with the Laser drive signals that are sent from the SCNT board. This Laser light passes through the cylindrical lens to fall on the 4-faced polygon mirror that is rotating at a fixed speed. The Laser light is reflected from the 4-faced polygon mirror and passes through the imaging lens, and reflects from the reflection mirror to scan the photosensitive drum in the toner cartridge. BD Malfunction The CPU on the ECNT board determines a BD malfunction if the /BDI signal is not detected within 0.1 second after the scanner motor is forcibly driven. Or, if the detected cycle of the /BDI signal has not reached the specified value within 2 seconds after the scanner motor reached its specified rotation number. Laser/scanner unit Malfunction If the /BDI signal is not detected within 1.5 seconds after the scanner motor is forcibly driven, the CPU on the ECNT board extends the time to 120 seconds, the CPU determines a scanner malfunction. The Laser/scanner unit contains parts that require adjustment that cannot adjust in the field. Never disassemble the Laser/scanner unit.

6.6 Modem and NCU Tests

The Modem and NCU Test menu is selected by pressing the numeric button 4 from the test mode menu. These tests test modem and NCU transmission and reception. The modem tests check whether signals are sent correctly from the modem by comparing the sound of the signals from the speaker with the sounds from a normal modem. Also, you check on the display whether or not the modem correctly detected received tone signals and DTMF signals. End this test by pressing the Stop button. Modem test type Frequency test G3 signal transmission test Tonal signal/DTMF signal reception tests V.34 G3 signal transmission test Overview The modem sends tonal signals from the modular jack and the speaker. The modem sends G3 signals from the modular jack and the speaker. The modem detects specific frequencies and DTMF signals received from the modular jack. The modem sends V.34 G3 signals from the modular jack and the speaker.
