1-2-1 Consumables
( 1 ) PaperKeep paper in a cool, dry place away from direct sunlight. If the facsimile is not going tobe used for a long period, remove the paper from the paper feed tray and seal in thewrapping paper it was originally supplied in.
( 2 ) Imaging unitKeep the Imaging unit in a cool and dry place away from direct sunlight. Always store ithorizontally. Storing it upside down or on its side may result in poor printing or leakingtoner.
1-2-2 Precautions for Operation
1. Do not open the machine while printing is in progress; it will cause a jam.2. Attach the paper feed tray correctly. A jam may otherwise occur.3. Adjust the positions of the width guides according to the width of the paper to be
used. A jam may otherwise occur.4. Do not open the ADF cover while document reading is in progress; it will cause a
jam.5. Adjust the positions of the width guides according to the width of the document to be
used. A jam may otherwise occur.6. Only use documents of the same width at one time. A jam may otherwise occur.7. Replace the imaging unit when “REPLACE IU” (For inch models), “CHANGE IU” (For
metric models) appears on the message display to keep the printed image clean andclear.
8. Always keep the imaging unit horizontally.9. While checking the laser scanning unit, PROTECT yourself from the laser, which is
invisible and can harm the eyes.

1-2-3 Document
( 1 ) Types of documentThis machine can use the following types of document • Sizes: Folio, A4R - A5R/81/2" × 14" - 51/2" × 41/4"
(Width: 140 mm - 216 mm, 51/2" - 81/2", Length: 128 mm - 1000 mm, 51/16" - 391/4")(However, documents that are longer than 355 mm/14" must be assisted by handwhile they pass by. Also, the maximum length setting can be changed with memoryswitch No. 51.)
• Thickness: 50 g/m2 - 160 g/m2
• CapacityUp to 20 documents can be set on the document table at one time. (However, paperof any thickness other than 64 - 80 g/m2 or of a smaller size such as A5, 81/2" × 51/2"should be fed one at a time.)
[Precautions] • The area within 4 mm from top or bottom and 10 mm from right or left side of a
document may not be transmitted. • The size of paper printed at destination party may differ from the one which was used
for transmitting. • When an documents longer than the maximum length passes by, this is treated as a
document jam and “DOCUMENT JAM” is displayed in the message display. • Very low density characters may not be printed on the destination facsimile unit. • Do not transmit hand-written or stamped documents until they are completely dry. • Remove clips and staples from documents before transmitting. (After removing the
staples, fan the documents to ensure they do not stick together.) • Documents that do not meet size and thickness requirements may not be transmitted
successfully. • Do not feed different size documents through the ADF simultaneously or jams may
occur. • If some of the document are crinkled, bent or curled, make those flat, and be careful
to insert those documents.

( 1 ) Document feed/image reading sections (ADF)The document feed and image reading sections comprise the parts shown in Figure 1-3-10. This structure conveys the document set on the document table onto the contactimage sensor (CIS) and scans the document image.When a document is placed on the document table and the document detection switch(DDSW) comes on, the ADF motor (ADFM) comes on, the document is fed and stops atthe space between the ADF pad and the ADF paper feed roller, and the machine entersthe ready state in the transmission or the copy mode. (ADF preparatory operation). Afterthe preparatory operation completes, the ADF motor (ADFM) goes off. By pressing Startor Copy/Space key, the ADF motor (ADFM) comes on and the set document is fed inthe direction of the arrow shown in the figure 1-3-10 individually by the rotation of theADF paper feed roller, the ADF conveying roller, and the ADF eject roller. At this time,the ADF pad prevents multiple documents from feeding simultaneously.A image printed on the fed document is read when it passes on the contact imagesensor (CIS).

The horizontal scanning is provided by the polygon mirror while the vertical scanning isprovided by the rotating drum. The letter “A”, for example, is reproduced as a staticlatent image onto the drum surface as shown in Figure 1-3-17.The laser diode turns on at a position corresponding to a black dot dispelling electricalcharge from this position.The center of the laser beam spot on one scan line is separated from those on adjacentscan lines but adjacent scan lines overlap slightly.

( 4 ) Imaging unitThe imaging unit comprises the parts shown in Figure 1-3-18. The developing section,drum section, and main charger are combined in a single unit.
• Developing sectionThe developing section forms the toner image by making toner adhere to the latentstatic image formed onto the drum. The toner is agitated by the developing agitationpaddle and fed to the developing roller by the sub-roller.The toner fed onto the developing roller forms a uniform layer. The thickness of thelayer formed is held constant by the developing blade. At this time, the toner ispositively charged by the friction between the developing blade and the developingroller.Also, the developing bias voltage is applied to the developing roller and sub-roller. Thisbias voltage dominates the amount of toner developing (toner adhering) onto the drum.When the developing bias voltage is higher than the drum surface potential, the toneradheres to the drum, developing the image. Also, when the developing bias voltage islower than the drum surface potential, the toner does not adhere to the drum anddeveloping is not carried out.The developing bias voltage is set to + 400 V (image area voltage) and is applied at thesame time as the main charging starts. However, normally when the + 400 V biasvoltage is applied, the area between the main charger and the developing roller wherethe main charger does not charge (non-image area) passes the developing roller, thedeveloping bias voltage is higher than the drum surface potential of that area and tonerdeveloping (adhering) occurs. Therefore, on this machine, when printing, until the non-image area passes the developing roller, a – 200 V (non-image area section voltage)developing bias voltage is applied to prevent developing of the non-image area.
• Drum, main chargerBy applying high voltage (+ DC) to the charger wire, positive corona discharge is carriedout and the drum OPC layer is positively charged. The charger grid is installed on themain charger so that the charge discharged by the charger wire charges on the drumevenly. Also, in order to remove paper powder etc. from the drum, a cleaning brush isinstalled on the main charger.

Timing chart 1-3-2 Imaging unit operation
• Imaging unit operationsA When the image writing is ready and the M.SYNC signal comes on, the main motor
(MM) comes on and the machine drive starts. At the same time, the main chargerand the developing bias (DB1 REM) come on. At this time, the non-image areavoltage 1 (– 200 V) is output as the developing bias voltage.
B 1.5 s after the main motor (MM) comes on, the developing bias change signal 1 (DBCHG1) comes on and in order to carry out the non-image/image area changecorrectly, the developing bias voltage is changed to the non-image area voltage 2 (0V).
C 0.2 s after the developing bias change signal 1 (DB CHG1) comes on, thedeveloping bias change signal 2 (DB CHG2) comes on and the developing biasvoltage is changed to the image area voltage (+ 400 V).
D When the printing is complete, the paper is ejected, and the eject switch (ESW)goes off, then the main motor (MM), main charger, and developing bias go off.

( 5 ) Transfer/charge erasing sectionsThe transfer/charge erasing sections comprise the parts shown in Figure 1-3-20.
• Transfer rollerThe transfer roller is installed above the drum and electrically transfers the toner imageonto the drum surface to the paper. High voltage (– DC) is applied to the transfer roller(inductive urethane foam roller), charging a negative charge larger than the positivetoner charge charged on the drum surface, attracting the toner on the drum surface tothe paper, and thus transferring the toner image to the paper.1 s after the paper feed switch (FSW) comes on, the transfer roller (transfer charge)comes on and 1 s after the paper feed switch (FSW) goes off, the transfer roller(transfer charge) goes off.
• Cleaning lampThe cleaning lamp (CL) removes the residual charge on the drum surface by lighting tothe drum so that the toner remaining on the drum surface after transfer is correctlyrecovered to the imaging unit (developing section).The cleaning lamp (CL) comes on at the same time as the main motor (MM) and goesoff when the main motor (MM) stops for reverse processing.

( 6 ) Fixing sectionThe fixing section comprises the parts shown in Figure 1-3-22. The fixing section usesheat and pressure to fuse the toner image transferred to the paper. The heat roller isheated by the fixing heater (H). During printing, the heat roller temperature is controlledto be a constant 160°C/320°F by switching the fixing heater on/off according to the heatroller surface temperature detected by the fixing thermistor (TH). When printing ends,the fixing heater (H) goes off.If the temperature becomes abnormally high, the fixing thermistor (TH) detects the hightemperature abnormality, fixing thermostats 1 and 2 (FTH1, 2) go off, and the powersupply to the fixing heater (H) is cut off.The press roller is pressed against the heat roller by the press springs at both ends. Thepressure between the press roller and heat roller is approx. 39.2 N (19.6 N one side).
• Separating the paper from the heat rollerThere are two separation claws on the fixing unit lower housing. When the paperpasses the fixing section, they prevent the paper from sticking to the heat roller andwrapping around it. The separation claws are constantly pressed in the direction ofcontact with the heat roller by the separation claw spring.

2-2-1 Paper jam detection
Paper jams are detected by the on and off timing of the switch equipped with the paperor document conveying path.
When a paper jam occurs, the error indicator lights up and a message of the paper jamis displayed on the message display. Also, for printing a PC, the status monitorindicating the paper jam is displayed on the computer screen too.
When a paper jam occurs, open the machine main body, then remove the jammedpaper. Also, if a document jam occurs, open the ADF cover and remove the jammeddocument or press the Stop/Reset key to eject the jammed document.
In order to reset for the paper jam, opening and closing the machine main body (turn offand on the safety switch).
A document jam is reset by turning on and off the document detection switch (DDSW) orADF timing switch (ADFTIMSW).In order to reset for the document paper jam, open the ADF cover and then remove thejammed document or press the Stop/Reset key and then eject the jammed document.
When the paper jam detected state is reset, the error indicator goes out and themessage in the message display goes out.

2-3-6 Communication Procedures
( 1 ) Outline
There are two different procedures available for facsimile transmission, one being usedfor communicating between our facsimiles and those of other manufacturers and theother being used for communication between our facsimiles.The facsimile machine has two standard modes, the internationally used and recog-nized G3 standard and our own standard.In the G3 mode, the facsimile machine automatically responds in the mode the othermachine is using.Our own standard can be selected and used only if the user selects it. If the othermachine does not use our standard, the facsimile automatically goes into the normal(G3) mode.

4. Fallback procedure
This facsimile uses two types of fallback procedures, TCF and image signal. The actualtraining is a task performed by the modem and the fallback procedure is based on thattask.
1) TCF (Training check) fallbackWhen the FTT response is received by the same speed TCF, the communication speedis lowered and the TCF is transmitted. However, receiving FTT at a 2400 bps TCF willresult in a communication error and the facsimile transaction will abort.
